General Power Tool Safety

Warnings

WARNING
Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire, and/or serious in-jury.

SAVE ALL WARNINGS AND INSTRUCTIONS FOR FUTURE REFERENCE!

The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

Work Area Safety

• Keep work area clean and well-lit. Cluttered or dark areas invite accidents.
•  Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks that may ignite dust or fumes.
•  Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

Electrical Safety

•  Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodi -fied plugs and matching outlets will reduce the risk of electric shock.
•  Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electrical shock if your body is earthed or grounded.
•  Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electrical shock.
•  Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
•  When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.

The text used in the General Power Tool Safety Warnings section of this manual is verbatim, as required, from the applicable UL/CSA/EN 62841-1 standard. This section contains general safety practices for many different types of power tools. Not every precaution applies to every tool, and some do not apply to this tool.

• If operating a power tool in a damp location is unavoidable, use a ground fault circuit interrupter (GFCI) protected supply. Use of a GFCI reduces the risk of electric shock.

Personal Safety

•  Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol, or medication. A mo ment of inattention while operating power tools may result in serious personal injury.
• Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
•  Prevent unintentional starting. Ensure the switch is in the OFF position before connecting to a power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energizing power tools that have the switch ON invites accidents.
•  Remove any adjusting key or wrench before turning the power tool ON. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
•  Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
•  Dress properly. Do not wear loose clothing or jewelry. Keep your hair, and clothing away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts.
•  If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. The use of dust collection can reduce dust-related hazards.
•  Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.

Power Tool Use and Care

•  Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it is de-signed.

• Do not use a power tool if the switch does not turn it ON and OFF. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.

•  Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.

•  Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the tool. Power tools are dangerous in the hands of untrained users.

•  Maintain power tools and accessories. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.

•  Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.

•  Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. The use of the power tool for operations different from those intended could result in a hazardous situation.

•  Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.

Service

• Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is main-tained.

Specific Safety Information

WARNING
This section contains important safety informa-tion that is specific to this tool. Read these precautions carefully before using the K-50 Drain Cleaner to reduce the risk of electrical shock or another serious injury.

SAVE ALL WARNINGS AND INSTRUCTIONS FOR FUTURE REFERENCE!
Keep this manual with machine for use by the operator.

Drain Cleaner Safety

•  Before using the tool, test the ground fault circuit interrupter (GFCI) provided with the power supply cord to ensure it is operating correctly. A properly operating GFCI reduces the risk of electrical shock.

•  Only use extension cords that are protected by a GFCI. The GFCI on the machine power cord will not prevent electrical shock from extension cords.

•  Only grasp the rotating cable with gloves recommended by the manufacturer. Latex or loose-fitting gloves or rags can become wrapped around the cable and may result in serious personal injury.

•  Do not allow the cutter to stop turning while the cable is turning. This can overstress the cable and may cause twisting, kinking or breaking of the cable and may result in serious personal injury.

•  One person must control both the cable and switch. If the cutter stops rotating, the operator must be able to turn the tool OFF to prevent the cable from twisting, kinking and breaking.

•  Use latex or rubber gloves inside the gloves recommended by the manufacturer, goggles, face shields, protective clothing, and a respirator when chemicals, bacteria or other toxic or infectious substances are suspected to be in a drain line. Drains may contain chemicals, bacteria, and other substances that may cause burns, be toxic or infectious or may result in another serious personal injury.

•  Practice good hygiene. Do not eat or smoke while handling or operating the tool. After handling or operating drain cleaning equipment, use hot, soapy water to wash hands and other body parts exposed to drain contents. This will help reduce the risk of health hazards due to exposure to toxic or infectious material.

•  Only use the drain cleaner for the recommended drain sizes. Using the wrong size drain cleaner can lead to twisting, kinking or breaking of the cable and may result in personal injury.

•  Always use the rear guide hose while operating the tool and ensure the cable does not extend beyond the rear guide hose. This prevents the cable from whipping which may result in entanglement and personal injury.

•  Keep a mist-covered hand on the cable whenever the machine is running. This provides better control of the cable and helps prevent twisting, kinking and breaking of the cable and may result in serious personal injury.

• Position machine cable outlet within 2′ (0.6 m) of the drain inlet or properly support exposed cable when the distance exceeds 2′ (0.6 m). Greater dis-tances can cause control problems leading to twisting, kinking or breaking of the cable. Twisting, kinking or breaking cable may cause striking or crushing injuries.

•  One person must control both the cable and the clutch. Do not lock clutch handle during operation. If the cutter stops rotating, the operator must be able to release the clutch to prevent twisting, kinking and breaking of the cable and reduce the risk of injury.

•  Do not operate the machine in REV (reverse) rotation except as described in this manual. Operating in reverse can result in cable damage and is used to back the cable end out of blockages.

•  Do not wear loose clothing or jewelry. Keep your hair and clothing away from moving parts. Loose clothing, jewelry or hair can be caught in moving parts.

•  Do not operate this machine if the operator or machine is standing in water. Operating a machine while in water increases the risk of electrical shock.

•  Do not engage the drain cleaner clutch (rotate cable) while any part of the cable is in the cable carrier. This may cause striking or crushing injuries.

•  Do not use if there is the risk of contact with other utilities (such as natural gas or electric) during operation. Visual inspection of the drain with a camera is a good practice. Crossbores, improperly placed utilities and damaged drains could allow the cutter to contact and damage the utility. This could cause electrical shock, gas leaks, fire, explosion or other serious dam-age or injury.

•  Read and understand these instructions and the instructions and warnings for all equipment and materials being used before operating this tool to reduce the risk of serious personal injury.

Description, Specifications and Standard Equipment

Description

The RIDGID K-50 is a portable Drain Cleaning Machine designed to clean 11/4″ to 4″ drain “lines. Applications include a sink, shower, and floor drains. Capable of running three different size cables: 5/16″, 3/8″ and 5/8”.

The machine is driven by a 1/6 HP motor that has a grounded electrical system. An integral Ground Fault Interrupter (GFCI) is built into the line cord. A toggle switch provides FORWARD/OFF/REVERSE control of the motor.

The K-50 is designed to use 5/8  diameter sectional-type cable that has a quick change coupling system for dis-connecting tools. The cable is manually fed in and out of the drain and rotates at a speed of 400 RPM. The rotation of the cable is controlled by a clutch handle. The cable stops instantly when the clutch handle is released.

The K-50 is also designed to use with the A-17 Adapters. Adapters will hold 5/16″ or 3/8″ continuous length cables. The rotation of the adapters is controlled by the clutch handle. The cable adapter is equipped with a quick- acting brake which immediately stops the rotation of the drum when the clutch handle is pulled upward.

Machine Inspection

To prevent serious injury, inspect your Drain Cleaning Machine. The following inspection procedures should be performed before each use.

1.  Make sure the Drain Cleaning Machine is unplugged and the directional switch is set to the OFF posi-tion.(Figure 1).

2.  Inspect the power cord, Ground Fault Circuit Inte r -rupter (GFCI) and plug for damage. If the plug has been modified, is missing the grounding prong or if the cord is damaged, do not use the Drain Cleaning Machine until the cord has been replaced.

3.  Inspect the Drain Cleaning Machine for any broken, missing, misaligned or binding parts as well as any other conditions which may affect the safe and normal operation of the machine. If any of these conditions are present, do not use the Drain Cleaning Machine until any problem has been repaired.

4. Lubricate the Drain Cleaning Machine, if necessary, according to the Maintenance Instructions.

5.  Use tools and accessories that are designed for your drain cleaner and meet the needs of your application. The correct tools and accessories allow you to do the job successfully and safely. Accessories suitable for use with other equipment may be hazardous when used with this drain cleaner.

6.  Clean any oil, grease or dirt from all equipment handles and controls. This reduces the risk of injury due to a tool or control slipping from your grip.

7.  Inspect the cutting edges of your tools. If necessary, have them sharpened or replaced prior to using the Drain Cleaning Machine. Dull or damaged cutting tools can lead to binding and cable breakage.

8. x Inspect cables and couplings for wear and damage. Cables should be replaced when they become severely worn or corroded. A worn cable can be identified when the outside coils become flat.

WARNING : Worn or damaged cables can break caus-ing serious injury.

Machine Set-Up

Do not place the machine in water. Water entering the motor can result in electrical shock. To prevent serious injury, proper set-up of the machine and work area is required. The following procedures should be followed to set up the ma-chine:

Set-Up For 5/8″ Sectional Cable

1.  Check work area for:

2. Adequate lighting

3. Grounded electrical outlet

4. Clear path to the electrical outlet that does not contain any sources of heat or oil, sharp edges or moving parts that may damage the electrical cord.

5. Dry place for machine and operator. Do not use the machine while standing in water.

6. Flammable liquids, vapors or dust that may ignite.

7. Position the Drain Cleaning Machine within 2′ of drain inlet. The greater distance can result in cable twist-ing or kinking.

8.  Make sure FOR/OFF/REV switch is in the OFF position.
   

9. Attach the rear guide hose by lifting up the lock pin and sliding guide hose adapter onto the housing until it locks into place (Figure 2).
   WARNING Do not use the machine without rear guide hose attached. Prevents cable whipping and possible entanglement.

10.  Insert the first cable into the front of the machine (female end first) and push through guide hose until approximately one foot remains out the front of the machine (Figure 3).
    WARNING Never couple more than one cable at a time. The cable will extend behind the rear guide tube.

11.  Select and install the proper tool to the end of the cable. The T-Slot Coupler allows the tool to be snap -ped into the cable coupler (Figure 4). To remove tool, use the pin key to depress the plunger and slide the coupling apart.
    
    NOTE! Proper Tool Selection
    A good rule of thumb is to use a tool at least 1″ smaller than the line to be cleaned. The style of the tool is determined by the nature of the job and is left up to the operator.

12.  Plug the Drain Cleaning Machine into the electrical outlet, making sure to position the power cord along the clear path selected earlier. If the power cord does not reach the outlet, use an extension cord in good condition.

WARNING To avoid electric shock and electrical fires, never use an extension cord that is damaged or does not meet the following requirements:

•  The cord has a three-prong plug similar to shown in the Electrical Safety section.
•  The cord is rated as “W” or “W-A” if being used outdoors.
•  The cord has sufficient wire thickness (16 AWG – 100′). If the wire thickness is too small, the cord may overheat, melting the cord’s insulation or causing nearby objects to ignite.

WARNING To reduce the risk of electrical shock, keep all electrical connections dry and off the ground. Do not touch plug with wet hands. Test the Ground Fault Circuit Interrupter (GFCI) provided with the electric cord to ensure it is operating correctly. When test button is pushed in, the indicator light should go off. Reactivate by pushing the reset button in. If indicator light goes on, the machine is ready to use. If the GFCI does not function correctly, do not use the machine.

Set-Up For 5/16″ or 3/8″ Cable Adapters

1.  Make sure FOR/OFF/REV switch is in the OFF position.
2.  Pull ten inches of cable from the cable adapter and slide into the back of K-50.
3.  Lift plunger pin on cable adapter and depress clutch handle on the machine to allow cable adapter to slip into the drilled hole (Figure 5). Be sure the plunger has locked into the machine.

NOTE! By pulling down hard on the clutch handle, the adapter will spin. With an upward snap of clutch han-dle, the adapter will stop instantly, preventing overrun or kinking. The built-in brake increases the life of the cable.

• Position machine as close to line opening as possible and follow same set-up procedure as described for use with 5/8″ sectional cable.
•  Check that the adapter stops instantly when the clutch handle is pulled upward. If adapter coasts, see the Special Procedures section to adjust the brake.

Operating Instructions

Wear mitts with rivets provided with the machine. Never grasp a rotating cable with a rag, lose fit-ting cloth or leather glove that may become wrapped around the cable causing serious injury.
Always wear eye protection to protect your eyes against dirt and other foreign objects. Wear rubber-soled, non-slip shoes.
Be very careful when cleaning drains where clean-ing compounds have been used. Wear gloves when handling cable and avoid direct contact to the skin and especially the eyes and facial area as se-rious burns can result.
Do not operate if the clutch handle is damaged or does not function properly. A Clutch is a safety feature designed to stop the rotation of cable or adapters when released.
CAUTION It is important to know the approximate distance from inlet to main sewer or septic tank. Over-run ning cable too far into main sewer or septic tank can cause ca-bles to knot up and prevent their return through the small line.

Cleaning Drain using 5/8″ Sectional Cable

1. Assume the correct operating posture in order to maintain proper balance (Figure 6).
   WARNING Should an unexpected situation arise, this posture provides you with the opportunity to safely keep control of the machine and cable.
   Be sure you can quickly release the clutch handle.
   Hand must be on the cable to control its twisting action when it hits an obstruction.
   Must have access to FOR/OFF/REVERSE switch.
   

2.  Without turning the machine on, pull sufficient cable out of the machine to start tool and cable into the drain inlet. Push cable into inlet as far as it will go.

3.  Pull enough extra cable through the machine to form almost a half-circle between the machine and line opening.

4.  Hold cable loosely in mitted hand. Put FOR/OFF/RE-VERSE switch in FOR (forward) position.
   NOTE! The motor will start but the cable will not rotate.

5. With a mitted hand on the cable, push down on clutch han- dle with the opposite hand to engage cable. Push down on top of the cable loop with a definite snap to advance the cable.
   NOTE! A slow or gradual engagement of the clutch handle causes excessive wear of the jaw set. The clutch is instant-acting and returning clutch handle to its original position frees cable instantly.

6. As soon as excess cable has gone into line, release the clutch handle and pull six to ten inches of cable out of the machine with a mitted hand

7.  Continue to feed the cable into the line until resistance or obstruction is encountered. This will become apparent to operator as it will be difficult to feed the additional cable into line and/or the cable will have a tendency to twist sideways in the operator’s hands.

8.  If cable loads down in the obstruction, relieve the load by pulling back on cable with short, quick jerks to free cutter. Slowly advance cable back into the obstruc-tion. Repeat this process until the obstruction is clear. Remember, make sure the cutter is rotating atall times and never force the cable. At this point, pro gress depends upon the sharpness of the tool and nature of the obstruction

WARNING
Do not allow tension to build up in the cable. This will happen if the cutting tool hits a snag and stops turning, but the motor and cable continue to rotate. Torque builds until the cable suddenly twists, potentially wrapping around your hand or arm. This can happen quickly and without warning, so pro- ceed slowly and carefully as you feed the cable into the drain. Releasing clutch handle will stop the cable from rotating and releases the torque. If tool gets hung up in an obstruction, refer to Reverse Operating Instructions in the “Special Procedures” section.

•  Once the obstruction is cleared, it is recommended that operator flush debris from line with running water. Repeat Step 8 several times if necessary for a thorough cleaning job and then work cable through additional stoppages as required.
•  To add cable, the following procedure should be fol-lowed:
  After reaching the end of each cable section, turn the machine OFF.
  Secure the cable by looping it in the line (Figure 7). This procedure is especially useful when cleaning a line that has rapid fall, such as working from a stack line.

• With line secured, insert another section of cable in through the front of the machine (female end first) until approximately one foot remains out the front of the machine.
•  Attach cable to cable in line and resume operation.
• To retrieve cable from the drain line, the following procedure should be followed:
  Leave FOR/OFF/REV switch in FOR (forward) position.
  Push down on clutch handle to engage cable. With a mitted hand pull the cable out of line (if possible) or hold cable against the edge of the inlet to thread the cable out until loop forms in front of  the machine.

NOTE! By holding the cable against the edge of the inlet, in the FOR (FORWARD) position, the rotation will rapidly “thread” the cable out of the line.

• When loop forms, release the clutch handle and push the excess cable back through the machine. Disconnect one section at a time.

WARNING When disconnecting sections, remember to turn the unit off and secure cable in line.

• Once a section of the cable is removed, insert the secured cable in through the front of the machine and continue removing sections until tool on last section of cable is just inside sewer inlet.
  WARNING Never retract tool from sewer inlet while the cable is rotating. Tool can whip causing serious injury.

• Turn FOR/OFF/REV Switch to OFF position.

•  Pull remaining cable and tool from the sewer.

WARNING After using, thoroughly flush and drain cables, couplings and tools with water due to damaging effects of some drain cleaning compounds.

Cleaning Drain Using 5/16″ or 3/8″ Cable Adapter

1. Assume the correct operating posture in order to maintain proper balance (Figure 6).
   WARNING Should an unexpected situation arise, this posture provides you with the opportunity to safely keep control of the machine and cable.
   Be sure you can quickly release the clutch handle.
   The hand must be on the cable to control its twisting action when it hits an obstruction.
   Must have access to FOR/OFF/REVERSE switch.

2.  Pull out enough cable by hand to insert into the drain opening and hand-feed the cable into drain until it stops feeding easily. Push cable down drain line keeping your control hand close to the drain opening.

3.  Hold cable loosely in mittened hand, put FOR/OFF/REV SWITCH in FOR (forward) position.
   NOTE! The motor will start but the cable will not rotate.

4. With a mitted hand on cable, push down on clutch handle with the opposite hand to engage adapter.

5.  Continue hand-feeding the cable slowly until the drain is opened or blockage is encountered.
   WARNING Keep your cable hand close to the drain opening to keep control of the cable and help prevent cable flip-over.

6.  When you reach the blockage, work the cable back and forth to clear the obstruction. At this point, progress depends on the type of tool being used and nature of the blockage. Advance cable slowly.

7.  If cable gets hung up in the obstruction, release the clutch handle to stop the rotation of the cable. Refer to “Reverse Operation” in the “Special Procedures” section.

8.  Once the obstruction is cleared, it is recommended that the operator flush debris from line with running water. Repeat Step 6 several times if necessary for a thorough cleaning job and then work cable through additional stoppages as required.
   WARNING Cable is not attached inside the drum. When approaching the end of the cable, keep your hand securely on the cable to avoid losing it down the drain.

9.  To withdraw cable from line with the machine running, leave FOR/OFF/REV lever in forwarding position and slowly pull the cable from drain.

10.  As the excess cable is retrieved from the line, hand-feed cable back into K-50.

11.  Release clutch handles just prior to cable or tool emerging from the drain opening. The cable or tool may contain debris and splash work area.
    WARNING Never retract tool from sewer inlet while the cable is rotating. Tool can whip causing serious injury.

12.  Turn FOR/OFF/REV switch to OFF position.

13.  Pull remaining cable and tool from the sewer.

Special Procedures

Reverse Operation
Running the machine in reverse will cause premature failure of cable. Use reverse only to free a tool or cable caught in an obstruction. If this should occur, immediately release clutch handle and place FOR/OFF/REV switch to OFF position. After the motor comes to a complete stop, place FOR/OFF/REV switch in the REV (reverse) direction. Engage clutch handle only until cable or tool is free of obstruction. Once it is free, release clutch handle immediately. Turn unit OFF. Run unit in FOR (forward) direction and follow normal operating procedure.
WARNING Never operate this machine in REV (re-verse) for any other purpose. Operating in reverse can damage a cable and cause serious injury.

Brake Adjustment
The cable adapter is equipped with a quick-acting brake which will immediately stop rotation of the drum when the clutch handle is pulled upwards.
After attaching cable adapter to your K-50 Machine, test for proper braking action as follows:

1. Put the switch in a forwarding position to start the motor.

2. Push clutch handles forward to engage clutch driver jaws. The drum will rotate.

3.  Pull up on the clutch handle to release jaws and activate the brake. The drum should stop turning immediately.
   If drum does not stop immediately, readjust brake mech-anism as follows:
   WARNING
   Make sure the machine is unplugged from the power source before making any adjustments.

4. Slightly loosen two set screws “A” using a 5/32″ hex wrench (Figure 9).

5.  Turn set screw “B” clockwise 1/4 turn (Figure 9).

6.  Operate machine to check for proper braking action.

7.  If drum does not stop immediately, repeat Steps 2 and 3 until brake functions properly.

8.  Tighten set screws “A” and recheck tension on set screw “B”.
   Due to normal wear, future adjustment will become nec-essary for effective braking.

Maintenance Instructions

WARNING

Make sure machine is unplugged from power source before performing maintenance or mak-ing any adjustments.

Lubrication
Lubricate machine with grease at grease fitting (located on jaw housing) once a week if used every day; once a month if used less. Place a drop of oil on each of the bear-ing points, thrust bearing, clutch jaws, etc., at least once a year.

Cables
Cables should be thoroughly flushed with water to prevent damaging effects of sediment and drain cleaning com-pounds. Periodically lubricate cables and couplings with RIDGID Cable Rust Inhibitor.
When not in use, store cables indoors to prevent deterioration by the elements. Cables should be replaced when they become severely corroded or worn. A worn cable can be identified when outside of coils become flat.

Clutch Jaw Assembly (Jaw Set)
The clutch jaw assembly should be periodically cleaned.

1. Place machine on its nose end. Remove the two (2)socket head cap screws from the rack and pinion housing with a 1/4″ hex key (Figure 10).
   

2. Remove the rack and pinion housing. The clutch jaw assembly is contained in the K-50 housing.

3.  Clean and lubricate clutch jaw assembly with oil.

4.  If worn, replace the clutch jaw assembly.

5.  Reinstall the jaws into the housing and replace the rack and pinion assembly.

6.  Attach rack and pinion housing to machine with socket head cap screws.

Cable Containers
The cable container on 5/16″ and 3/8″ cable adapter should be periodically cleaned.

1. Remove the cable from the cable adapter. Cable is not attached to the inside of the drum.
2.  Remove three 1/4″ screws holding tube and flange to the drum.
3.  Clean inside of drum and flange assembly. Certain cleaning agents and solvents damage plastic parts. Some of these are: gasoline, carbon tetrachloride, chlorinated cleaning solvents, ammonia and household detergents that contain ammonia. Avoiding use of these and other types of cleaning agents minimizes the probability of damage.
4. Reinstall the flange assembly to the drum and replace the cable.

Machine Storage
WARNING Motor-driven equipment must be kept in-doors or well covered in rainy weather. Store the machine in a locked area that is out of reach of children and people unfamiliar with drain cleaners. This machine can cause serious injury in the hands of untrained users. If the machine has been exposed to freezing weather, unit must be run for ten (10) to twenty (20) minutes without load to warm up. Failing to do this will result in frozen bearings. If the machine is exposed to the weather for a period of time, moisture will form across motor windings causing the motor to burn out.
