ATD-7322 Air Hydraulic Axle Jack

SAFETY AND GENERAL INFORMATION

Save these instructions. For your safety, read, understand, and follow the information provided with and on this jack before using. The owner and operator of this equipment shall have an understanding of this jack and safe operating procedures before attempting to use. The owner and operator shall be aware that use and repair of this product may require special skills and knowledge. Instructions and safety information shall be conveyed in the operator’s native language before use of this jack is authorized. If any doubt exists as to the safe and proper use of this jack, remove from service immediately.

Inspect before each use. Do not use if broken, bent, cracked or damaged parts are noted. Any jack that appears damaged in any way, or operates abnormally shall be removed from service immediately. If the jack has been or suspected to have been subjected to a shock load (a load dropped suddenly, unexpectedly upon it), immediately discontinue use until jack has been checked by a factory authorized service center (contact distributor or manufacturer for list of authorized service centers). It is recommended that an annual inspection be done by qualified personnel. Labels and Operator’s Manuals are available from manufacturer.

PRODUCT DESCRIPTION

These Air/Hydraulic Axle Jack are designed to lift, but not support, rated capacity partial vehicle loads consisting of one end of a vehicle. Immediately after lifting, loads must be supported by a pair of appropriately rated jack stands.

NEVER use a hydraulic truck jack as a stand-alone device. After lifting, immediately supportthe lifted vehicle with a pair of appropriately rated jack stands.

PREPARATION

Assembly (see Replacement Parts page 6 for reference to parts location & assembly sequence) Assemble, align and insert the handle assembly and handle position bar into the handle sleeve, then tighten the bolt on handle sleeve to prevent accidental removal of handle while in use.

Before Use

1. Verify that the product and application are compatible, if in doubt call ATD Tools Technical Service line (636)327- 9050

2. Before using this product, read the operator’s manual completely and familiarize yourself thoroughly with the product, its components and recognize the hazards associated with its use.

3. To familiarize yourself with basic operation, locate and turn the release valve (handle knob):
   a. Clockwise until firm resistance is felt to further turning. This is the ‘CLOSED’ release valve position used to raise the load.
   b. Counter-clockwise, but no more than 1 full turn from the closed position. This is the ‘OPEN’ release valve position used to lower the load. The more you turn the release valve counter-clockwise, the faster the load descends.

4. With ram fully lowered, remove the oil filler screw. Check oil level. Proper oil level should be just below the rim of the opening. Reinstall the oil filler screw.

5. Pour a teaspoon of good quality air tool lubricant into the air supply inlet of the lift control valve. Connect to air supply, then squeeze the lift control valve for 3 seconds to evenly distribute lubricant.
   Note: These models are equipped with the popular 1/4″ NPT air coupler. When installing a different air coupler of your choice, ensure that thread tape or compound is used when servicing connections. To ensure dependable, trouble free operation an inline air dryer and oiler is recommended.

6. Ensure that jack rolls freely. Raise and lower the unloaded ram throughout the lifting range before putting into service to ensure the jack operates smoothly. Replace worn or damaged parts and assemblies with ATD Tools authorized replacement parts only.

Bleeding / Venting Trapped Air
With the release valve in the OPEN position (3b.) and with ram fully lowered, locate and remove the oil filler screw.
This will help release any pressurized air which may be trapped within the reservoir. Reinstall the oil filler screw.

WARNING

• Study, understand, and follow all printed materials provided with/on this product before use.
• Do not exceed rated capacity.
• This is a lifting device only!
• Immediately after lifting, support the load with a pair of appropriately rated jack stands.
• Use only on hard, level surface.
• Lift only on areas of the vehicle as specified by the vehicle manufacturer.
• Never wire, clamp or otherwise disable the lift control valve to function by other than operator’s hand.
• No alterations shall be made to this product.
• Failure to heed these markings may result in personal injury and/or property damage.

WARNING

To avoid crushing and related injuries:

• Never work on, under or around a load supported only by hydraulic jack.
• Always use adequately rated jack stands.
• Chock each unlifted tire in both directions.
• Do not use this device to lift, level, lower, support nor move a house, mobile home, travel trailer, camper or any building structure.
• Be alert and sober when using this product. Do not operate under the influence of drugs or alcohol.

The wheels provided with this jack are for positioning the jack under a load ONLY! The wheels are not load wheels. Do not try to dolly or move the vehicle with the jack!

OPERATI ON (see Fig 1)

Lifting

Note: The jack is equipped with handle position lock. To adjust the handle, release lock device by pulling the lever up, lever is spring loaded and will lock into desired position. Ensure lever locking mechanism is fully engaged before leaving

1. Connect adequate air source to the air supply inlet.
2. Follow the vehicle manufacturer’s recommended guidelines for lifting. Engage the emergency brake and chock each unlifted wheel in both directions to prevent inadvertent vehicle movement.
3. Close the release valve by turning the handle knob clockwise until firm resistance is felt.
4. Center jack saddle under lift point, then squeeze the lift control valve until saddle contacts the lift point. To lift, continue squeezing the lift control valve until load reaches desired height. Simply release your grip on the lift control valve to end lift event.
5. Transfer the load immediately to appropriately rated jack stands.

Only attachments and/or adapters supplied by the manufacturer shall be used. Lift only on area of the vehicle as specified by the vehicle manufacturer.

NEVER use hydraulic jack as a stand alone device! ALWAYS transfer the lifted load IMMEDIATELY to a pair of appropriately rated jack stands. Use one pair of jack stands per vehicle. Rated capacity is per pair only! Do not exceed rated capacity.

Lowering

Be sure all tools and personnel are clear before lowering load. Slowly open the release valve! The more you turn the handle knob counter-clockwise, the faster the load will come down. Maintain control of the rate of speed at which the load lowers at all times!

1. Raise load high enough to clear the jack stands.

2. Remove jack stands carefully (always used in pairs).

3. Slowly turn handle knob counter-clockwise, but no more than 1 full turn. If the load fails to lower:
   a. Use another jack to raise the vehicle high enough to reinstall jack stands.
   b. Remove the malfunctioning jack and then the jack stands.
   c. Use the functioning jack to lower the vehicle.

4. After removing jack from under the vehicle, fully retract the jack to reduce ram exposure to rust and contamination.

MAINTENANCE

Important: Use only good grade hydraulic jack oil. Avoid mixing different types of fluid and NEVER use brake fluid, turbine oil, transmission fluid, motor oil or glycerin. Improper fluid can cause premature failure of the jack and the potential for sudden and immediate loss of load. We recommend Mobil DTE 13M or equivalent.

Adding/ Changing Oil
For best performance and longest life, replace the complete fluid supply at least once per year.

• With saddle fully lowered remove cover plate, then oil filler screw.

• Lay jack on its side and drain fluid into a suitable container.
  Note: Dispose of hydraulic fluid in accordance with local regulations.

• Set jack in its upright, level position.

• Fill with oil. Proper oil level is just below the rim of the opening. Reinstall the oil filler screw.

Lubrication
A periodic coating of light lubricating oil to pivot points, axles and hinges will help to prevent rust and assure that wheels move freely and the pump functions smoothly. To help ensure trouble free operation, an inline air dryer and oiler is recommended.

Cleaning
Periodically check the ram for signs of rust or corrosion. Clean as needed and wipe with an oily cloth.
Note: Never use sandpaper or abrasive material on ram surfaces!

Storage
When not in use, store the jack with saddle fully lowered.

TROUBLESHOOTING
