•Read and understand the entire contents of this manual before attempting to use the body

repair kit.

•This body repair kit is designed and intended for use by properly trained and experienced

personnel only. If you are not familiar with the proper and safe use of a body repair kit, do

not use until proper training and knowledge has been obtained.

•Failure to comply with all of these warnings may cause serious injury.

1. Do not exceed the maximum load capacity of the ram.

2. Use only on hard level surfaces capable of sustaining the load.

3. Do not open oil filler screw unless ram is fully retracted and pressure is released.

4. Do not use as a vehicle lifting device, or as a vehicle support.

5. When extension tubes and/or offset attachments are used, the rated capacity is reduced by 50%

for each tube or attachment connected.

6. Make sure all attachments are fully engaged before applying load or pressure.

7. If bowing or bending of ram or any attachment occurs during use, STOP, release pressure

immediately and reconsider application. Application may not be compatible with product, a ram kit

with a higher rated capacity may be required.

8. Do not over extend the ram, as it is possible to force the plunger out of the top of the ram.

9. When coupler valves are disconnected, insert dust cap to keep the oil lines clean.

10. Monitor pressure and load at all times.

11. Make sure the load is centrally applied to attachment or ram saddle. Do not load off center.

12. Control the load. Dropping the load may cause the threads to shear and lose the load. Failure to

comply may result in serious injury or death.

13. Do not drop any heavy objects onto the hose, and do not allow the hose to kink.

14. Allow clearance for the hose to avoid damage to the hose and couplers.

15. Keep equipment away from heat or fire, as this may damage or weaken the equipment.

16. Wear approved safety glasses/face shields while using this machine.

17. Keep the floor around the body repair kit clean and free of scrap material, oil, and grease.

18. Do not over reach. Maintain a balanced stance at all times.

19. Use the right tool. Do not force a tool or attachment to do a job which it was not designed for.

20. Replace warning labels if they become obscured or removed.

21. Give your work undivided attention. Looking around, carrying on a conversation, and “horse-play” are

careless acts that can result in serious injury.

22. Keep visitors a safe distance from the work area.

23. Use recommended accessories. Improper accessories may be hazardous.

24. Some dust created by power sanding, sawing, grinding, drilling, and other construction activities

contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples

of these chemicals are:

•Lead from lead based paint

•Crystalline silica from bricks and cement and other masonry products, and

•Arsenic and chromium from chemically-treated lumber.

Your risk from those exposures varies, depending on how often you do this type of work. To reduce

your exposure to these chemicals: work in a well ventilated area, and work with approved safety

equipment, such as those dust masks that are specifically designed to filter out microscopic particles.

25. Do not operate tool while under the influence of drugs, alcohol or any medication.

Before Operating

1. Inspect the unit for evidence of fluid leaks,

damaged hydraulic fittings, or other damage

such as bent, broken, or missing parts. Fix

or replace as needed before operating.

2. Check the fluid level.

Place the pump unit on a level surface. Use

a flat blade screwdriver to remove the oil-fill

screw and seal from the top of the pump

cylinder (A, Fig. 1).

Fig. 1

If the fluid is below the metal rod inside the

pump, add enough good-quality hydraulic

fluid to just cover the rod. Do not overfill.

Replace the seal and tighten the screw.

Use only good-quality

hydraulic fluid. Improper fluid can cause

premature failure of the jack, and the

potential for sudden and immediate loss of

load. Failure to comply may cause serious

injury!

Fluid Maintenance

On a yearly basis, drain and refill the hydraulic

fluid for optimum performance.

1. To drain, open the release valve. Remove

the screw and seal. Invert the pump and

drain the fluid in to a suitable container. Do

not let dirt get into the system.

2. Refill with good-quality hydraulic fluid.

IMPORTANT! Dispose of hydraulic fluid in

accordance with local regulations. Avoid mixing

different types of fluid, and NEVER use brake

fluid, transmission fluid, motor oil, or glycerin.

Operation

The pump can be used in a vertical or horizontal

position. Always keep the hose end of the pump

unit facing down when using in the vertical

position.

1. Connect the hydraulic pump hose to the

hydraulic ram. Tighten the connection firmly

prior to pumping.

2. Close release valve (B, Fig. 2) by turning it

clockwise. Do not over tighten.

Fig. 2

3. Pump the handle until the ram reaches the

desired distance or pressure required.

4. Release the pressure by turning the release

valve counter-clockwise.

Storage

1. Make sure the release valve on the pump

unit is open and the ram is in the retracted

position when not in use.

2. Keep parts and attachments in the case

when not in use.

Troubleshooting

Trouble Probable Cause Remedy

covered with fluid. Do not

overfill.

2. Check the hose and replace

if necessary. Make sure all

connections are tight.

Replace seals if needed.

3. Open the release valve.

Pump the handle a couple of

full strokes. Close the

release valve.

Pump unit will not lower

completely

1. Air trapped in the system

2. The reservoir could be

overfilled or low on hydraulic

fluid
