Safety Instructions

Read all instructions in this manual before operating the lift unit to avoid severe injury or death. All of the steps and procedures in this manual relate to the safe use of the lift system. Contact the manufacturer using the contact information on the back cover of this manual if you have any questions about this unit or its instructions and warnings. DO NOT use this product unless you know exactly what you are doing and are sufficiently trained and capable of using the lift system safely (see the Warnings on page 4). When using the lift system, always adhere to basic safety precautions, including the following:

IMPORTANT SAFETY INSTRUCTIONS

WARNING

Failure to know, understand, and obey the procedures, instructions and warnings contained in this manual could result in severe injury or death.

• DO NOT use the lift system to raise a vehicle by the frame or structural member. Lift vehicles with the lift system only by the vehicle’s wheels (except when using manufacturer supplied special-purpose adapters for their intended application).

• The lift system is to be used only in sets of 2, 4, 6, or 8 lift units –NEVER as a single lift unit. The only exception to this requirement is when using a single unit in Tire Mode as described in Section 2.14. Lift only on the same axle.

• DO NOT raise or lower one side of a vehicle (except when using Tire Mode). Lift units should ALWAYS be used in pairs to lift wheels on opposite ends of the same axle.

• DO NOT raise one end of a vehicle if the opposite end is supported by stands or another lifting device. When using two lift units to raise one end of a vehicle, the opposite end of the vehicle must be in contact with the ground, transmission in neutral and parking brake released. The only exception to this requirement is when using the lift system in single or paired mode as described in Section 2.11 of this manual.

• DO NOT use the lift system in conjunction with any other equipment used to raise a vehicle (e.g., any other jacks or lifts that are not part of the lift system).

• DO NOT use blocks, non-factory supplied adapters or cribbing devices with the lift system.

• No alterations shall be made to this product except those explicitly discussed in this manual (e.g., use of optional adapters).

• DO NOT place hands, feet, other body parts, or clothing between the lift carriage and the column. There are potential pinch points that can injure hands and fingers or possibly grab clothing and pull body parts into pinch points.

• NEVER stand under the load or vehicle when it is being raised or lowered.

• To reduce the risk of fire, do not operate equipment in the vicinity of open containers of flammable liquids (gasoline).

• To reduce the risk of electric shock, do not use on wet surfaces or expose to rain.

• Do NOT remove the lifting forks for use on any different model of lift. Doing so could result in instability of the lift where the forks are installed.

• Do NOT remove base extensions from the lift. Both base extensions must remain in place at all times. Removal of base extensions could result in instability of the lift.

CAUTION

• DO NOT use the lift system as a wheel dolly or for any other purpose than raising vehicles by the wheels (except when using manufacturer supplied special-purpose adapters for their intended application).
• Always keep the covers closed on the lift units.
• Care must be taken as burns can occur from touching hot parts.
• Do not operate equipment with a damaged cord or if the equipment has been dropped or damaged – until it has been examined by a qualified serviceman.
• If an extension cord is necessary, a cord with a current rating equal to or more than that of the equipment should be used. Cords rated for less current than the equipment may overheat. Care should be taken to arrange the cord so that it will not be tripped over or pulled.
• Adequate ventilation should be provided in the work area.
• Keep hair, loose clothing, fingers, and all parts of body away from moving parts.
• Use only as described in this manual. Use only manufacturer’s recommended attachments.
• ALWAYS WEAR SAFETY GLASSES. Everyday eyeglasses only have impact resistant lenses, they are NOT safety glasses.
• To reduce the risk of electric shock or fire, never overload receptacles. Refer to markings for the maximum load on receptacles.

NOTICE

• Maximum capacity for an individual lift unit is listed on the lift unit’s ID decal. DO NOT overload any individual lift unit in the lift system.
• Do not let cord hang over edge of table, bench, or counter or come in contact with hot manifolds or moving fan blades.
• Never use the cord to pull the plug from the outlet. Grasp plug and pull to disconnect.
• Let equipment cool completely before putting away.
• The optimal operating ambient temperature range is 41-104°F (5-40°C). Use of lift units outside this temperature range may result in degraded performance and reduced service life.
• A qualified person should be consulted to address seismic loads as well as other state and local requirements.

Installation, Operation and Maintenance

Operating Instructions

Prepare the Work Area

It is important that the surrounding area be properly chosen and prepared before raising a load. Refer to ANSI/ALI ALIS for additional information.

• Use the lift system only on hard surfaces capable of safely supporting the load. The surface must be strong enough to support the weight of the lift units and the vehicle being raised. The ground pressure for each lift unit is listed in the Specifications section. The ground pressure listed assumes the entire footprint of the lift unit is in full contact with the floor.

• Use the lift system only on level, even surfaces. A level surface is considered to be 3° slope or less. A surface with 3° slope is equivalent to a 5% grade or 5/8 in. (15.9 mm) rise or drop per horizontal foot (304.8 mm) as shown below. The surface must also be free of ripples, ridges, depressions, holes, or any undulation (e.g., a seam in a concrete floor) that would cause only part of the lift unit’s footprint to be in contact with the floor.

• Make sure there is adequate clearance above the highest point of the vehicle (including things like vehicle exhaust pipes, air dams, etc.) so the vehicle does not contact any overhead objects when raised (e.g.
  ceiling/roof structural components, duct work, hanging lights, heating/AC units, etc.). The lift system can raise a vehicle as much as 69” (1,753 mm) (when four or more units are used together), but the vehicle will extend vertically above this. The height of the lift unit alone when raised to 69” (1,753 mm) is 157.13” (3,991 mm).

• Clear the work area (especially the area underneath the lift unit) of any unnecessary personnel, tools, equipment, and other materials. No unauthorized personnel should be allowed in the work area where the lift system is being used. A horizontal area 36” (914 mm) deep and 30” (762 mm) wide in front of the operation panel must be kept clear while the lift is in operation.

•  The lift system must only be used in the environmental conditions listed below.  WARNING! The lift system is NOT approved for outdoor installation or use.

  • Do NOT use lift units when air speeds exceed 20 mph to avoid tipping or loss of load.
  • Do NOT leave lift units unattended. This will help to avoid inadvertent operation by untrained operators and unforeseen changes in environmental conditions.
  • Do NOT use lift units in an area where moisture is present. There is a risk of electric shock if lift units are used in a wet environment.
  • Do NOT charge lift units in a wet environment. Only charge lift units in a dry area to avoid risk of electric shock.

If these conditions cannot be met, move the vehicle and lift units (separately) to an area where the lifting operation can be performed safely. WARNING! NEVER attempt to move or reposition a lift unit when a vehicle is raised on the lift unit.

Prepare the Vehicle
It is important that the vehicle be in proper condition before raising it off the floor.

• The vehicle’s wheels (or rims; not the tires) must meet the minimum wheel diameter requirement shown in the Specifications section on page 5 or else they could fall through the cradle of the lift carriage (for example, if the tires deflate). See Section 2.3 for information about how to properly engage a tire.
• Check that the tires on the vehicle are properly inflated and are in road-worthy condition. Make sure the weight on any single tire does not exceed the rated capacity of its lift unit, as the total weight of the vehicle may not be evenly distributed across all lifted tires. Also, be sure to consider the weight carried by unsupported axles (i.e. a set of 4 lift units used to raise a vehicle with three axles).

Prepare the Lift Units
It is important to prepare the lift units so they can be used safely together.

• Make sure to use an appropriate number of lift units for the type and weight of the vehicle to be lifted. Determine how many lift units will be needed to raise the vehicle by calculating the weight of the vehicle and the load applied to each lift unit when the vehicle is raised. NEVER exceed the rated capacity of an individual lift unit. Also, the lift system is to be only used in sets where lift units are positioned on opposite ends of the same axle– NEVER as a single lift unit or on only one side of a vehicle unless using Tire Mode as described in Section 2.14.
• Before each use, you should inspect each lift unit for any visible signs of wear or damage. See the Section 10 on page 34 for details about how to inspect the lift unit. WARNING! If you see any signs of wear or damage, or if there is any indication that the lift unit is not performing normally, immediately take it out of service and contact the manufacturer. NEVER use a lift unit that appears damaged in any way.
• Before each use, plug in each lift unit and make sure the battery charger indicator light is green for both batteries on each lift unit (see Section 5.2 on page 22 of this manual). If the light is not green, charge the battery until the battery charger indicator light is green. Failure to fully charge the battery before use can reduce the life of the battery.
• Transport the lift units to the work area by either wheeling them manually or lifting and transporting them with a forklift (see Section 4 on page 21). A lift unit can be wheeled to the work area over smooth, level surfaces for short distances. Transport the lift units by forklift if traveling over longer distances and/or rough or uneven surfaces.
• Position the lift units at opposite ends of the same axle. If necessary, adjust the carriage lift arms (See Section

8. until they are wide enough to allow the lift pads to clear the tire tread. Make sure the lift pads cradle the tires evenly and are aligned with the tire. Position the lift pads under the tire so the entire lift pad is under the tire (see Figure 1). Lower the base to the ground using the handle once the lift unit is properly positioned (see Section 4 for more information). WARNING! The carriage lift arms must be positioned so they are centered on the lift carriage. NEVER use the lift unit with the lift arms positioned in an off- center position since this can cause dangerous side loading of the lift unit.

• Place the vehicle transmission in neutral and release the parking brake.

Control Box Initialization

• Make sure the master on/off switch (see the “Component Identification” section on page 6) on all lift units is turned to the OFF position.

• Turn the master on/off switch of the first lift unit to the ON position. The green colored touch screen power indicator light located just below the screen should turn on once the master on/off switch is turned ON. It will take 15-20 seconds for the touch screen to completely start up and be ready to use. The Main Menu screen (see Section 2.15 for more information) will be shown with a series of icons on the screen. Select the Lift Program button to start the program used to lift a vehicle. NOTE: After completing startup, the screen may automatically change to the Lift Program screen. If this occurs, then the step of selecting the Lift Program button can be skipped.

• The control box will initialize and then the screen shown below will appear on the touch screen. (NOTE: All screens shown in this manual are simplified versions of what is actually shown on the display to help clarify button locations and functions.)
  

• Select the desired radio settings. The default radio settings will be the settings selected the last time the unit was used. Touch the screen on top of the Settings on the right side of the screen and then slide up or down to scroll through the settings. Then, touch to select the desired radio setting. All units that will be used together as a lift system to lift a vehicle must be set to the same radio setting. There are 12 radio frequencies available for use and 20 different channels that can be used for each frequency. Refer to Section 7 for more information on selecting the radio settings. When the desired radio settings are shown, push the Confirm button to advance to the next screen. NOTE: Do not rush and push the Confirm button before the control box has completely initialized. Wait until the radio settings update to show the previously used settings before pushing the Confirm button.

•  Read through the Notice that is displayed on the next screen. If the operator agrees with and acknowledges the statements made on the screen, push the Accept button to continue setting up the lift system.

•  The display then changes to ask how many lift units will be used in the lift system. Push the button that matches the total number of lift units that will be used in the current lifting system.

•  A screen will now appear asking which operating mode will be used. Select the desired operating mode from the list of modes displayed. If the vehicle is being lifted by the tires using the standard lift arms select Normal Mode. Only select one of the adapter modes if using a manufacturer supplied adapter. See the Owner’s Manual supplied with the adapter for complete operating instructions. WARNING! Use of the wrong operating mode can result in serious injury, death, and/or property damage due to a vehicle tipping or falling from the lift system. ONLY use one of the adapter modes when the correct manufacturer supplied adapter is properly installed on the lift unit.

• The display will now appear as shown below with a picture of a vehicle asking for the current lift unit’s position relative to the vehicle. Select the round button with a number inside it that matches the current lift unit’s position. Once the position is selected the position button will turn green to indicate the selection.
  

• Now move to the second lift unit (the units can be turned on in any order) and turn the master on/off switch to the ON position. The same screen shown in Step (c) above will appear after the screen has completed its startup.

• Select the same radio setting as was chosen in Step (d) by sliding the settings buttons up and down on the right side of the screen. When the correct radio setting is highlighted, push the Confirm button.

• The display will now show the same screen as shown in Step (h) above. Select the round button that matches the position of the current lift unit relative to the vehicle. Positions that have already been selected will be shown by a yellow-colored button.

• Repeat Steps (i) through (k) on all remaining units that will be used in the current lifting system.

• If operating in Normal Mode, once all the units in the lifting system are initialized (radio settings and position relative to the vehicle selected) the screen on all units will appear as shown below. Some of the adapter modes will show a different screen that requires additional setup before lifting the vehicle. If any error messages are shown during initialization consult Section 12 on page 36.
  NOTE: If at any time the screen is not touched for more than 5 minutes the screen saver will be activated. The screen saver will display the battery voltage of all the lifts in the system to help identify any lifts that may need to be charged. To exit from screen saver mode simply touch anywhere on the screen.

Information Panels

• There are three information panels available on the Main Operation screen. Each panel can be directly accessed by pushing on the corresponding button located near the top of the screen (see Section 2.5). The panels can also be opened by swiping left and right in the middle of the screen. To return to the Main Operation screen either swipe left until the panels are no longer shown or push the Truck Indicator button to return directly.
• The first panel is the Battery Voltage panel and it can be accessed by pushing the Battery Charge Level button. The Battery Voltage panel shows the real-time battery voltage of all the lifts in the lifting system. The voltages will update even while the lift is raising or
• lowering. The Battery Voltage panel can be used to help identify and troubleshoot battery issues. For example, if two lifts are lifting close to the same amount of weight the battery voltage while raising should be similar on both lifts. If the battery voltage on one lift is significantly lower it may need to be charged or the batteries may need to be replaced.
• The second panel on the Main Operation screen is the Weight panel which can be opened by pushing the Weight button. This panel will show the current weight being lifted by each of the lifts in the lifting system. It also shows the total vehicle weight calculated by adding up the weight on each individual lift. The weight readings are most accurate if all the lifts are stationary. All the weights shown are only estimates and should not be used in place of properly calibrated and certified vehicle scales.
• The third panel is the Radio Signal Strength panel and it is displayed when the Radio Setting button is pushed. This panel shows the strength of the radio signal used to communicate among the lifts in the lift system. This information can be helpful when determining the best radio settings for a given environment.

Raising/Lowering the Vehicle
Once the work area, vehicle, and lift units are prepared perform the following steps:

• Position yourself at any one of the lift units.
• Push and release the Enable button. The button color will change from red to green indicating the button is ON. The button will stay ON (green) for 5 seconds after it is released. If no other buttons are pushed during the 5 seconds the button will automatically turn OFF (red) at the end of the 5 seconds.
• During the 5 seconds that the Enable button is ON (green), push and hold the Raise or Lower button to raise or lower the vehicle. NOTE: The down stop catch pawls will automatically pull back and release when the Lower button is pushed. During lowering the vehicle will automatically lower at a slower speed for the first 6 inches of travel. This slow start feature allows the vehicle to be gently placed on stands. After the first 6 inches of travel the vehicle will lower at normal speed for the remainder of time the Lower button is pushed.
• As the vehicle raises or lowers the height indicator on the screen will update to show the current height.
• When the vehicle is at the desired height release the Raise or Lower button.
• If desired, Park mode can be activated on the lift unit to mechanically support the load on the down stop system and relieve the hydraulic system pressure. Follow the steps in Section 2.12 to activate Park mode. NOTE: Even if Park mode is not activated the down stop system will automatically stop the load from lowering should the hydraulic system lose pressure.
• Depending on the amount of time the vehicle will remain in the current position the lift system should be either locked or turned off. If the vehicle will be raised or lowered before the end of the shift, the lift system should be locked by following the steps in Section 2.9. If the vehicle will be left in the raised position longer than 8 hours, turn the master on/off switch on all lift units in the system to the OFF position to conserve the batteries.

WARNING! There are several important safety issues to consider when raising a vehicle or whenever a vehicle is in a raised position, including:

• All personnel should be instructed that the system should not be unlocked or restarted unless all objects and personnel are out from underneath the vehicle and the vehicle, work area, and lift units are prepared for lifting or lowering.
• If the lift units are to be removed from a raised vehicle, use only stands intended for this purpose. Use appropriate vehicle support stands when a raised vehicle is to be left elevated for an extended amount of time. Appropriate stands must be capable of supporting the load and they must be made specifically for high-rise supporting.
• NEVER attempt to climb up, climb on, or get in a raised vehicle. Do not open the vehicle’s doors or make adjustments to the exterior when raised, as it could interfere with safe lowering of the vehicle.
• NEVER start the vehicle’s motor when it is supported by the lift units or stands. Only start the engine when the vehicle is firmly in contact with the ground and the lift units have been removed from the wheels.
• NEVER attempt to move a vehicle horizontally by any means when it is raised on the lift system. Once the vehicle is raised, it should only be moved up or down. Also, NEVER attempt to move or reposition a lift unit when a vehicle is raised on the lift unit.
• NEVER subject a lift unit to dynamic loading (i.e. “shock loading”). NEVER add objects or other weight to the vehicle once it has been raised on the lift units.

If you experience any problems while raising the vehicle or while it is raised, consult Section 6 on page 25 and/or Section 12 on page 36 of this manual.

Changing the Maximum Lift Height

The maximum lift height can be adjusted by pushing the Supervisor Settings button (see Section 2.15). A prompt will appear asking for the password. The password is “1234” without the quotes. After entering the password and pressing OK the Supervisor Settings screen will appear. Push on the box that shows the current max height. A window will appear where a new maximum height can be entered. The allowed range for the maximum height is between 1.0 and 69.0 inches (2.5 – 175.2 cm). If a height outside this range is entered it will be ignored and the previous maximum height will continue to be used. Confirm the box showing the current maximum height is correct before exiting from this screen.

NOTE: The maximum height is adjustable on each individual lift unit. When multiple lift units are used together in a system all lifts in the system will stop at the lowest maximum height setting of any individual lift. For example, consider a system with four lifts. The maximum height is set at 48 inches (121.9 cm) on the first lift and 62 inches (157.5 cm) on each of the second, third, and fourth lifts. When the lifts are operated all four of the lifts will stop at 48 inches (121.9 cm) since this is the lowest maximum height setting on any of the lifts in the system.

Locking the Lift System

•  Push the Options button (gear shaped button in the top left corner of the screen).
• After the menu appears on the left side of the screen select the padlock button in the middle.
• A message will appear asking whether Password Lock will be used. If No is selected then the system will display a message showing it is now locked. If Yes is selected then a prompt will appear to create a password that will be required to unlock the system. Enter a ssword and push OK. The system should now display a message showing the system is locked.
• When ready to unlock the system, return to the unit where the lock button was pushed (shown by the flashing yellow position indicator) and push the Reset button. If Password Lock was not used the system will now be unlocked. If Password Lock was used, enter the same password created in step c to unlock the system.

Lowering the Vehicle to the Ground

WARNING! To avoid serious injury or death, NEVER drive the vehicle off the lift units or attempt to move a vehicle that is elevated by the lift system. a. Clear the work area under the vehicle of all personnel, tools, and equipment. Make sure there are no obstruc-tions under the vehicle or under the lift carriages of the lift system prior to lowering the vehicle to the ground.

• If the lift system was locked, unlock the system by following the steps in Section 2.9. If the lift system was turned off, follow the steps in Section 2.4 to reinitialize the system. If Park mode was activated, refer to Section 2.12 prior to lowering the vehicle.
• Position yourself at any one of the synchronized lift units.
•  Push and release the Enable button. The button color will change from red to green indicating the button is ON. The button will stay ON (green) for 5 seconds after it is released. If no other buttons are pushed during the 5 seconds the button will automatically turn OFF (red) at the end of the 5 seconds.
• During the 5 seconds that the Enable button is ON (green), push and hold the Lower button to lower the vehicle.
• Release the Lower button when the vehicle is lowered to the floor and the lift carriages no longer contact the tires. This condition will be indicated when the Stowed indicator turns blue.
• Place the vehicle’s transmission in gear (or park) and engage the vehicle’s parking or air brake.
• Move the lift units away from the work area and turn the master on/off switch to the OFF position. About 10 seconds after the master on/off switch is turned OFF the screen will display a message and power down. This will ensure the lift units are ready to be synchronized for lifting in the future and conserve the batteries while the lift system is not in use.
• Completely recharge each lift unit after use.

Single/Paired Operation

In some situations it may be desirable to place only one wheel or one axle on stands instead of placing the entire vehicle on stands. The lift system features a special mode of operation called single/paired mode to allow this. The system can be placed in single/paired mode at any height.

•  If only one wheel of the vehicle will be placed on a stand, position yourself at the lift unit that is positioned on that wheel of the vehicle. If one axle will be placed on stands, position yourself at one of the lift units on the ends of the axle to be supported.

• Push the Single/Paired button on the main operation screen shown in Section 2.5.

•  A screen will appear asking whether the system will be operated in single mode or paired mode. If only one wheel will be supported on stands push the Single button. If one axle will be supported on stands push the Paired button. Pushing the Exit button will return to the main operation screen.

• The screen shown below (paired mode is shown in this example, single mode would be similar) will be displayed on the lift unit where single or paired mode was initialized. All other lift units will be locked out from operation and show a screen indicating this condition.

•  All the buttons shown function in the same way as described in Sections 2.5 and 2.6. The vehicle can be raised or lowered as needed to place stands and support the vehicle. The distance the vehicle can be raised or lowered is limited while in single or paired mode.

• When all work that required the wheel/axle to be supported on a stand(s) has been completed, move the lift unit(s) back into position under the wheel(s). The lift unit(s) can be raised or lowered to help with properly positioning the lift carriage under the wheel(s). Push and release the Enable button and then within 5 seconds push and release the Auto Return button. The lift unit(s) that was raised or lowered in single or paired mode will automatically adjust its height to match the other units in the system and support the vehicle.

• Once the lift unit(s) has adjusted its height to match the rest of the system, all the screens will return to the screen shown in Section 2.5. The system will now operate as a whole with all lift units raising or lowering together.

Park Mode

If desired, the load on the lift carriage can be transferred from the hydraulic cylinder to the mechanical down stop system by activating Park mode. The following steps explain how to activate Park mode.

•  Follow the steps in Section 2.6 to position the vehicle at the desired working height.
• Push and release the Enable button and within 5 seconds push and release the Park button. The lift system will now lower until the down stop catch pawl engages the down stop slots on all lift units in the system.
• Once all the units in the system have Parked, the Parked indicator will turn blue. The Lower button and Park button will also disappear since the vehicle will need to be raised off the down stop catch pawl before it can be lowered.
• To exit Park mode, simply push and release the Enable button and then within 5 seconds push and hold the Raise button until the Parked indicator light turns off. The vehicle can now be raised or lowered normally.

Options
The Options button displays additional buttons that are normally hidden from view on the screen. Pushing the Options button displays a panel on the left side of the screen that includes the Lock button and the About button. To hide the panel that is displayed when the Options button is pushed, push the Back button.
The Lock button is used as described in Section 2.9 to lock the system from operating. Pushing the About button brings up a screen showing the contact information for the lift system manufacturer, the software versions currently installed, and the battery voltage. To exit the About screen push the Back button.

Tire Mode

Tire mode is a special operating mode that must only be used to change a tire on a vehicle with dual axles. Tire mode allows a single lift unit to raise to a limited maximum height. To use Tire Mode properly the following steps must be followed:

• The vehicle to be lifted must have dual axles.

• The tire to be changed must be on one of the dual axles.

• The lift unit must engage the wheel in front or behind of the tire to be changed on the same side of the vehicle as the tire being changed. Chock the front and rear of the tire on the opposite end of the axle from the tire being changed.

•  Follow the guidelines in Sections 2.1-2.3 to setup the work area, vehicle, and lift unit.

• Activate Tire Mode by pushing the tire icon shown below.

•  The lift unit can now be operated as described in earlier sections. The lift can be raised, lowered, parked, and  locked. The maximum lifting height is limited to prevent lifting the vehicle too high causing it to become unstable.

WARNING! Using Tire Mode for any other purpose than what is described in this section may cause a vehicle to be lifted in an unstable manner resulting in tipping or loss of load. Tire mode must ONLY be used exactly as described in this section. Failure to heed this warning could cause serious personal injury and/or property damage.

Main Menu Screen

Control Box Shutdown and Restart Procedure

The control box consists of two main parts- the control board and the touch screen which is an Android tablet computer. Just like any computer the touch screen will need to be restarted (rebooted) if it operates abnormally. Additionally, the control box should be shut down when the lift is not in use to conserve the batteries. Follow the steps below to shutdown and restart the control box.

• To shut down the control box turn the master on/off switch on the side of the lift unit to the OFF position. After about 10 seconds a message will be displayed and the screen will power down. The green touch screen power indicator light will also turn off once the control box has fully powered down. NOTE: Do not restart the control box until the green touch screen power indicator light has turned off or else problems may be experienced when the control box restarts. If the control box does not power down after waiting at least 10 seconds then the screen reset button shown in Figure 2 can be pushed and released to turn off the control box.
• To restart the control box turn the master on/off switch to the ON position. The touch screen will automatically turn on and the green touch screen power indicator light will turn on to indicate the control box is on even though nothing may be shown on the screen. After 15-20 seconds the control box will be completely restarted and ready for use.

Moving the Lift Unit in the Work Area

If a lift unit needs to be moved in the work area, either move it manually (with the handle and wheels) or with a forklift. A lift unit can be manually wheeled to the work area over smooth, level surfaces for short distances. WARNING! Jolting caused by the lift unit’s wheels catching on uneven surfaces can cause physical strain and personal injury. A lift unit should be transported by forklift if traveling over longer distances and/or rough or uneven surfaces. A forklift must also be used if the lift unit is being removed from a pallet (e.g., when the lift unit is shipped to the customer).

Moving the Lift Unit with the Handle

To move the lift unit for positioning, push down on the actuating lever (see Figure 3) to move it into the Raise position. Then, pump the handle by pulling it toward you until the base of the lift unit is raised the desired amount above the floor. The base can be raised a maximum of about 1 inch. Once the base is at the desired height, move the lever up to the Neutral position. The lift unit can now be maneuvered to the desired location. Once the lift unit has been positioned, the base should be lowered to the floor. The base is lowered by gently pulling up on the actuating lever to move it into the Lower position. The farther the actuating lever is pulled up the faster the base will lower to the floor. Remember, the base of the lift unit should always be lowered to the floor prior to lifting a vehicle.

Moving the Lift Unit with a Forklift

You can move the lift unit by forklift, using the two forklift pockets (see Figure 4) provided on each lift unit. Be sure the forklift forks are fully inserted into the forklift pockets and the lift carriage is fully lowered before lifting. Use only these pockets to move the lift units with a forklift.

 Battery Information

Battery Type

Each lift unit is equipped at the factory with two deep cycle batteries. These batteries have been selected to match the usage conditions found on the lift unit. If replacement batteries are needed, it is recommended to use only the same brand and model of batteries originally supplied with the lift unit. Do NOT mix old and new batteries or use different types/brands of batteries on the same lift unit.

Charging the Battery

The battery should be charged after each use to ensure the longest possible battery life and to avoid service interruptions. The batteries used on all lift system models can be charged before they are completely discharged and not develop a “memory”. The battery life and level of charge will be greatly improved if the batteries are charged before they are deeply discharged. NOTICE: Only use the supplied battery charger to charge the batteries. The supplied battery charger is designed for the type of batteries used on the lift units. Use of a charger not designed for the type of batteries on the lift units may cause under or overcharging that will reduce the life and capacity of the batteries.

The on-board battery charger is mounted inside the sheet metal cabinet above the door as shown in Figure 5. A cord reel is provided with every lift to assist in connecting the battery charger to AC power. If not already installed, follow the instructions provided with the cord reel to mount it on the left side of the lift unit. To charge the batteries extend the cord from the cord reel and plug it into an appropriate wall outlet. The cord is approximately 25 feet long when fully extended. If needed, an extension cord (see Table 1 below for proper cord selection) can be used to extend the reach of the cord reel. Always use a grounded extension cord with a plug style that matches the plug from the cord reel. Inspect the condition of every cord and plug and only use if they are free of defects. The amperage drawn by the battery charger is shown in Table 1. Four lift units (in any combination of models) should be able to charge simultaneously on the same circuit powered by a 20 Amp circuit breaker.

Table 1. Extension Cords

The battery charger provided on each lift unit is a “smart” charger. There are two sets of battery charger indicator lights (one for each battery) located above the door that indicate the status of the battery charger when it is plugged in (See Figure 5). The battery charger automatically goes through several different stages of charging to properly charge the batteries and can be left plugged in at all times without harming the batteries. A series of red, orange, and green lights will illuminate to indicate the charger is charging the battery. As the battery becomes more charged additional lights will illuminate to indicate the status. A pulsing green light means the battery is 100% charged and being optimized. A solid green light indicates the battery is fully charged and the charger has switched to its maintenance mode. The charger also includes a series of diagnostic lights that can be used to troubleshoot charging issues. See Table 2 for information about the charging and diagnostic lights.

Table 2. Battery Charger Indicator Lights

Diagnostic Lights

Operating Mode Lights

The charger has an auto-memory feature and will always use the previously selected operating mode when plugged in. The charger has two independent charging banks (one for each battery), and the operating mode must be selected for both banks. In normal operation there should never be a need to change the operating mode. If needed, the operating mode can be changed by inserting a blunt ended object (the flat end of a 1/8” drill bit or hex key is recommended) in the holes shown in Figure 5 to depress the mode button and change the operating mode.

Model CLHM-125EX

Installation, Operation and Maintenance

WARNING! The following warning statements are important for safe use of the batteries and the battery charger:

• Charge only batteries of the same type, voltage, cell number, and amp-hour capacities as shown on the label. Other types of batteries may burst causing personal injury and damage.
• To prevent electrical shock, do not touch either AC or DC uninsulated parts. Make sure all electrical connectors are in good working condition. Do not use connectors that are cracked, corroded, or do not make adequate electrical contact. Use of a damaged or defective
• may result in a risk of overheating or electric shock.
• Lead-acid batteries generate explosive gases. To prevent arcing or burning near batteries, do not disconnect DC charging cord from batteries when the charger is operating. Keep sparks, flame, and smoking materials away from batteries.
• Always shield eyes when working near batteries. Do not put wrenches or other metal objects across battery terminal or battery top. Arcing or explosion of the battery can result.
• Batteries produce hydrogen gas, which can explode if ignited. Never smoke, use an open flame, or create sparks near the battery. Ventilate the area when the battery is charging in an enclosed place.
• Lead-acid batteries contain sulfuric acid, which may cause burns. Do not get acid in eyes, on skin, or clothing. If contact with the eyes occurs, flush immediately with clean water for 15 minutes and obtain medical attention.
• Only a qualified service technician should program or service this equipment.
• Do not operate the charger if it has received a sharp blow, been dropped, or otherwise damaged. Have a qualified service technician examine and repair as needed.
• Do not disassemble the charger. Have the charger examined by a qualified service technician. Incorrect re-assembly of the charger may result in an explosion, electric shock, or fire.
• Use this battery and battery charger with the lift system only—NEVER use the battery and the battery charger for any other purpose. NEVER use an unapproved power source other than the battery to power the lift.
• DO NOT expose the battery charger to rain or snow. Extended exposure to humidity or liquids may damage the charger.
• To reduce risk of damage to electric plug and cord, pull by the plug rather than the cord when disconnecting the cord reel cord from the wall outlet.
• Make sure cord is located so that it cannot be stepped on, tripped over, or otherwise subjected to damage or stress.
• NEVER charge a frozen battery.

Battery Life

Keeping the batteries properly charged will extend the service life of the batteries. Repeated deep discharging of the batteries will damage the batteries, reduce service life, and reduce the performance of the lift unit. It is recommended to charge the batteries as often as possible, especially over a weekend, to maintain the uptime of the lift system and ensure the longest service life possible from the batteries.

Battery Maintenance

If the lift unit is equipped with AGM type batteries no periodic battery maintenance is required. If the lift unit is equipped with wet cell type batteries the electrolyte level inside the batteries should be checked monthly. Prior to checking the electrolyte level, the batteries should be fully charged (indicated by a solid green light on the battery charger). After opening each filler cap check that the electrolyte level is just below the filler tube in each cell. If any cell is found to have a low electrolyte level add distilled water to raise the electrolyte level until it is just below the filler tube.

Critical Battery Level Detected Message

Each lift unit is equipped with a circuit that automatically locks out the lift unit if the battery level gets too low to help prevent permanent damage to the batteries. When this lock out occurs a message of “Critical Battery Level Detected” will be displayed on the screen. If this message is shown the battery charger needs to be plugged in to recharge the batteries. Once the batteries have charged enough to allow the lift unit to operate again the “Critical Battery Level Detected” message will automatically disappear. At this point the lift unit will need to be reinitialized as described in Section 2.4. It may take over 30 minutes of charging before the message disappears and the lift unit is ready for use.
The same circuit that locks out the lift unit will also completely shut down the lift unit if the battery level remains low for a longer period of time. If a lift unit is ever found to be non-responsive and not able to start up normally it likely shut down due to a low battery level. Follow the steps in Section 2.16 to restart the control box.

Emergency Procedures

Emergency Stop

In the event that the system must be stopped immediately, the lift system has an emergency stop button located on the door just below the touch screen (see Component Identification on page 6). It is red in color and simply needs to be pushed in on any lift unit to halt a vehicle lift or lowering that may be in progress. The normal emergency stop condition will communicate with all lift units synchronized in the system to halt all lift units at once. After the situation is assessed, and it is determined that it is safe to continue lifting or lowering, the emergency stop button originally pushed in can be pulled back out and the Reset button pushed to reset the system. The Reset button must be pushed on the lift unit where the emergency stop button was activated.
In the unlikely event that the system would lose communication at the same time an emergency stop button is pressed and a lift unit is still moving, simply press the emergency stop button on the lift unit that is still moving. If this fails to stop the lift unit, turn the master on/off switch, located on the left side of the control enclosure (see Component Identification on page 6), to the OFF position. If this is the case, then the motor starter solenoid has likely welded shut and will have to be replaced before manual lowering can occur. Contact the manufacturer for instructions on replacing the motor starter solenoid.

Manual Lowering

Any time the controls are found to not be functioning while a vehicle is already raised, the vehicle may be lowered to the ground using the following steps:

• Open the door on each lift unit. The door is held in place by a latch on the right side.
•  Station a person at each lift unit.
• Each person must one at a time hold the manual raise/lower toggle switch down (see Figure 6). No motion should occur yet. If a lift unit lowers, release all manual raise/lower toggle switches, then verify all needle valves are closed (i.e., turned completely clockwise).
• Each person should slowly open the needle valve located on the power unit to begin descent while holding the manual raise/lower toggle switch down (see Figure 6).
•  Coordinate the rate of lowering by adjusting the needle valve—counterclockwise is FASTER and clockwise is SLOWER. Be sure to close all needle valves prior to the next use.

If one or more lift unit(s) does not move down initially, it may be resting on the down stop catch pawl. Fully close the needle valve and slightly raise the carriage to clear the down stop catch pawl. The carriage is manually raised by pushing and holding the manual raise push button while also pushing up on the manual raise/lower toggle switch. Once the carriage is clear of the down stop catch pawl, lowering can resume.

Lifting Multiple Vehicles in the Same Work Area

If you have 4 or more lift units in the same work area, it is possible to use them for separate lifting applications (e.g., lifting two different vehicles at the same time). Each set of lift units designated to work together to lift a particular vehicle is considered a lift system. Different lift units could be used in different lift systems at different times. For example, two units may be used as a lift system to raise the front end of a vehicle one day and those same two lift units might be used as part of a 4-unit lift system on another day. When using multiple lift systems in the same work area’

• Identify the lift units to be used together in the lift system.
• Before raising the vehicle, make sure each lift unit in the lift system is fully lowered and the master on/off switch is turned to the OFF position. This will ensure that the lift system will know exactly how many lift units are part of the lift system and they will all be prepared to work together. WARNING! Failure to turn the master on/off switch to the OFF position could cause individual lift units to retain incorrect settings from previous lifts or to retain incorrect information from their use in previous lift systems.
• During the control box initialization (see Section 2.4) make sure to select the same radio setting for all lift units in the system. Also, check the radio settings of all other lift units in the work area that are not part of the current lift system to make sure that no other lift systems (or any other individual lift units) are using the same setting.
• More than one lift system can operate on the same frequency as long as each system uses a different channel. Once a frequency is found that allows for operation with minimal signal loss faults, it is recommended to use the same frequency but different channels for all systems.

NOTE: The lift system’s wireless feature complies with Part 90 of the FCC Rules. Lift system operation is registration-free and there are no licensing requirements for the end user.

Adjusting Carriage Width

The width of the carriage lift arms on the standard width models can be adjusted to fit a wide range of vehicles and tires. The width of the carriage lift arms is adjusted by positioning the lift arms in the series of notches on the front of the lift carriage. The width of the carriage lift arms must be adjusted as close as possible to the tread on the tire while remaining centered on the lift carriage. WARNING! The lift arms must always be positioned so they are centered on the lift carriage. Positioning the lift arms in an off-center position can cause dangerous side loading of the lift unit.

Maintenance Instructions

WARNING
All inspection and maintenance procedures must be performed after the equipment has been removed from service. Failure to heed this warning may result in personal injury and / or property damage.

Lift Lockout, Tagout Procedure

If maintenance is required, the following procedure should be used to remove all hydraulic, mechanical, and electrical energy from the lift.

• Notify all lift users the lift will be taken out of service.
• Fully lower the lift to the stowed position.
• Remove the lift from service.
•  Turn the master on/off switch to OFF (see Component Identification on page 6).
•  Remove the lower cover of the lift.
• Remove the three ring terminals from the negative terminal on the top battery.
• Install desired lockout, tagout device on the three ring terminals.
•  Check for stored energy by attempting to raise the lift by using the manual controls found in section 6.2 on page 26.
• When all maintenance or repairs are completed; remove the lockout, tagout device, reconnect ring terminals to negative battery terminal, and install the lower cover on the lift.
• Notify all lift users the lift has been returned to service.

Monthly Maintenance Requirements

• Check oil level in the oil reservoir. Refer to Section 9.3 below.
• All warning and capacity labels should be readable and complete. Wash external surfaces of lift unit, labels, and decals with a mild soap solution. DO NOT use a pressure washer to clean the control box. Contact the manufacturer for replacement labels as needed.
• nspect battery terminal connections to make sure they are clean and residue free.
•  Apply grease to the grease fittings for the down stop catch pawl (see Section 9.5) and check that it rotates forward and backward freely.
•  Inspect structure for damage to contact surfaces, excessive wear, damaged or cracked welds and/or any abnormal conditions that could affect the performance of the lift units (see Section 10).

Adding Hydraulic Fluid

The hydraulic reservoir is mounted inside the lower cover (See Figure 6 on page 26).

• The lift carriage must be in the fully lowered position and the lift unit must be on a level surface.

• Remove the lift unit from service and turn the master on/off switch to OFF.

•  Open the door by releasing the latch on the right side.

• Clean around the surface of the oil fill plug to prevent contamination of the hydraulic oil system.
  Visually check the hydraulic oil level. The fluid level should be within a range from the bottom of the word “MONARCH” to 1” below the bottom of “MONARCH”. If the fluid level is low, remove the oil fill plug (see Figure 6) and add a high-grade hydraulic fluid equivalent to Phillips 66 Megaflow AW22 HVI. Do not overfill the reservoir. An air gap is required at the top for fluid expansion and to prevent spilling when  moving the lift unit. CAUTION! Do not use brake or transmission fluid. Use of the wrong fluid can deteriorate the seals and corrosion problems will occur.

• Re-install the oil fill plug. Clean up any spilled oil and close the door. Test the lift unit for normal operation.
  If the lift carriage does not rise to full height before the pump cavitates, check for air in the system. See Section 9.4 for instructions on how to bleed air from the hydraulic system. If this does not solve the problem, contact the manufacturer using the information on the back of this manual.

Bleeding Air from Hydraulic Cylinder

If the lift carriage is spongy or jumpy when either raising or lowering with no load, there is most likely air trapped in the cylinder. To remove the trapped air, perform the following steps:

•  Make sure there is no load applied to the lift unit.

• Open the door by releasing the latch on the right side.

• Raise the carriage by pushing up on the manual raise/lower toggle switch and pushing in on the manual raise push button (see Figure 6). Raise the carriage approximately two feet off the ground.

• Position a ladder behind the lift unit so you can reach the top of the cylinder. Use a 6 mm hex key to slightly loosen the vent screw (do not fully remove the vent screw) in the top on the cylinder, see Figure 8, while surrounding the port with a clean rag. You will hear the air escaping.

•  When oil starts to escape past the vent screw, retighten the vent screw. It may take some time to purge all the air depending on the amount of air trapped in the cylinder.

• he air will now be purged from the system. Clean up any oil residue that escapes from the cylinder.

• When you get down from the ladder, lower the carriage by pushing down on the manual raise/lower toggle switch and opening the needle valve on the power unit (see Figure 6).

•  To make sure no additional air gets into the system, the oil level in the hydraulic reservoir should be checked to ensure the reservoir has the proper oil level. Refer to Section 9.3 for more information.

Down Stop Catch Pawl Lubrication

If the down stop catch pawl is not rotating forward and backward freely it may be in need of lubrication as described in the steps below. WARNING! If after lubricating the down stop catch pawl the pawl still does not rotate freely forward and backward DO NOT use the lift unit. Contact the manufacturer using the contact information on the back of this manual.

• Open the door and locate the two grease fittings shown in Figure 9.
• Wipe the top of the grease fittings with a clean rag and apply good quality lithium grease to the grease fittings. Only apply 1-2 shots of grease to each fitting. Excessive greasing can cause the down stop catch pawl to operate slowly and is not recommended.
• Clean up any excess grease that is present.

Parts List

Structural Inspection

WARNING
Equipment must be removed from service and inspected for damage immediately if subjected to an abnormal shock or load. Failure to heed this warning may result in personal injury and / or property damage.

WARNING
It is critical that each lift unit be inspected regularly for any signs of wear or damage that might affect its ability to operate safely. Any lift unit that appears to be damaged in any way, is found to be badly worn, or operates abnormally must be removed from service until necessary repairs are made. Contact the manufacturer (using the information on the back cover of this manual) if you need to have a lift unit serviced or if you have any questions about how to address any wear or damage observed on a lift unit.

The employer, owner, and/or manager are responsible for maintaining the lift units in good, serviceable condition. Any parts found to be worn, damaged, or broken must be replaced with parts approved by the original lift manufacturer. Employees must be trained on how to inspect lift units. Before each use of a lift unit, the operator must visually inspect the lift unit for any abnormal conditions. Any lift unit subjected to an abnormal load or shock must be immediately removed from service and given a thorough inspection. The employer, owner, and/or manager must inspect (or appoint a knowledgeable person to inspect) each lift unit regularly. Regular inspections should be made weekly (if the lift unit is used daily) or monthly (if the lift unit is used only intermittently). Regular inspections should include the following:

• Check for any visual cracks, chips, or other signs of excessive wear.
• Raise and lower the lift carriage through its full range (up and down)—it should move smoothly.
• Inspect the slide pad and roller contact surfaces for damage, such as gouging, warping, etc.
• All controls should operate smoothly and freely.
• Inspect the lift unit for oil leaks. If oil leaks occur, investigate and correct the source of the leakage (refer to Section 9.3 of this manual). WARNING! Clean up any oil leakage immediately. Oil left on the floor can create a slipping hazard.
• Inspect the down stop catch pawl to make certain it rotates forward and backward freely. If the catch pawl does not move freely it may need to be greased. Refer to Section 9 of this manual.
• Check the positioning of the down stop catch pawl. Refer to Section 9 of this manual.

If you are not sure whether any identified wear or damage is “serious”, DO NOT use the lift unit. The time it takes to determine whether or not the problem is “serious” or to repair the problem is small compared to the time it will take to deal with the consequences of a lost load (which could include severe injury or death to personnel).

Troubleshooting

The following pages are a list of fault messages that may be shown on the control box and possible solutions. If the solution listed fails to correct the problem, contact the manufacturer using the contact information on the back cover of this manual. Please have the model number and serial number of your lift unit and control box available. The lift unit serial number is on a permanently attached plate attached to the left side of the lift unit (Figure 14). The serial number of the control box is on the back of the control box. The door must be opened to see the control box serial number (See Figure 14).

Possible Solutions

---|---|---
Recharge Needed|

• Energy level on one or more lift unit(s) has dropped below desired minimum – recharge before next lift.
• Further use without recharge could shorten battery life.

|

1. Plug cord from cord reel into wall outlet to charge batteries.

Low Battery

|

• Energy Level on one or more lift unit(s) has dropped to a point where further lifting will damage battery. However, vehicle can be lowered.
• Identified lift unit(s) must be recharged before further

lifting can take place.

|

1. Plug cord from cord reel into wall outlet to charge batteries.

Max.

Allowed Lift Height

|

• Lift system has reached the maximum height allowed for the present configuration of lift units.
• Using only two lift units will raise 32” maximum.

|

1.  Lift system may be lowered from this height.

Signal Loss|

• Communication from one or more lift units was lost.
• Can be caused by outside RF interference and is considered normal.
• Communication link needs to be reestablished.

|

1.   Check that the master on/off switch on all lift units in the lift system is still turned ON.
2.  Wait a few minutes to see if interference clears and lift system is able to automatically recover.
3.   If “Signal Loss” continues to reoccur, turn all lift units OFF , select another radio frequency several frequencies away, and re-synchronize the system. More than one lift system can operate on the same frequency as long as eachsystem uses a different channel.

Feedback Loop

|

·         Carriage position on one or more lift units is not responding properly to control box commands.

·         Carriage speed does not match control box output.

| 1.        Press Reset button to continue.

2.        If reoccurs, verify no obstructions with lift carriage.

3.        If no obstructions, check operation of linear position sensor by observing the height readout on the display.

Out-of-Sync| ·         Lift units heights are not within acceptable synchronization range.| 1.        Press Reset button to clear fault.

2.        Operate lift system in the opposite direction

|

• All lift units must be within 3” of each other to operate.

| temporarily to re-synchronize.

3.     If unable to re-synchronize, use manual lowering procedure and re-sync at ground level.

---|---|---

E-Stop

|

•  Red emergency stop button has been pushed IN on one or more lift units.
•   All red emergency stop buttons must be OUT to operate.

|

1. Determine cause of activation.
2.  Rectify condition and verify ready to operate.
3. Reset Emergency Stop Button and push Reset

button to continue.

Too Many to Lift

|

• Number of lift units on the current radio frequency and channel is more than the operator input during set up.
• Another lift system is already operating on the selected radio frequency and channel.
• Number of lift units set to a given radio frequency and channel must equal the number input during set up.

|

1. Find all lift units not intended to be used on current vehicle.
2. If other units are being used on another vehicle, switch channels and re-synchronize.
3. If other units are to be idle, verify all units are
4. OFF before synchronizing current system.

Too Few to Lift

|

• Number of lift units on the current radio frequency and channel is less than the operator input during set up.
• Number of lift units set to a given radio frequency and channel must equal the number input during set up.

|

1. Push Reset button to clear fault message.
2.   Find all lift units that are intended to be used and verify the master on/off switch is ON and the radio frequency and channel are correctly selected.
3.   If all units are ON and the radio frequency and channel are correctly selected, turn all OFF and restart. Ensure proper number of lift units is input when prompted.

Down Stop Error

|

• Down stop catch pawl on at least one lift unit is retracted while raising.
• All down stop catch pawls must be resting against the down stop plate before lift system will allow vehicle to raise.

|

1.  Lubricate down stop catch pawl.
2.   Check down stop catch pawl positioning.
3. ontact the manufacturer for assistance if problem persists.

Raise Before Lower

|

• Down stop catch pawl on at least one lift unit is not retracting properly.
• All down stop catch pawls must be fully retracted before lift system will allow vehicle to lower.

|

1. Raise the vehicle slightly before lowering. This will also correct the fault if caused by the lift system being in Park mode.
2. Lubricate down stop catch pawl.
3.  Check down stop catch pawl positioning.
4.  Contact the manufacturer for assistance if problem persists.

Park Error

|

• Down stop catch pawl on one or more lift units in the system did not properly engage a down stop slot when the Park button was pushed.
• All units must park on a down stop slot within 10 seconds.

|

1.  Raise the vehicle a few inches and try to Park again.
2. Lubricate the down stop catch pawl.
3. Check the down-stop catch pawl positioning.

Comm Error: SN

|

• A different lift unit than what was initially setup with the lift system has attempted to communicate with the lift system.
• A new lift unit cannot be added to an existing lift system to replace an existing lift unit unless all the lift units are turned OFF and restarted.

|

1.   Turn OFF all the lift units and restart the lift system.
2.  If the problem persists, turn OFF all the lift
3. units and restart on a different radio frequency or channel.
