SAFETY PRECAUTIONS
1. Read Instruction manual before use.
2. Only trained persons should operate this lifting equipment.
3. ALWAYS ensure that sufficient light is provided and that the work area is
kept clear of unrelated items.
4. ALWAYS inspect the jack before use. Make sure that all parts are in good
condition and operating smoothly and that no cracks or distortion is
apparent. If in doubt DO NOT use. Have the damaged parts replaced or
consult your CLARKE dealer.
5. The jack must be maintained and repaired by suitably qualified persons.
6. DO NOT make any modifications to this jack or adjust any valves.
7. DO NOT use the jack if an oil leak is apparent. Consult your CLARKE dealer.
8. DO NOT use to lift people and ensure that no-one is in the vehicle during
lifting.
9. NEVER exceed the rated load for the jack See “Specifications” on page ..
Overloading can cause the jack to fail resulting in personal injury.
10. Make sure that the jack is on a hard level surface, and there is no possibility
of it slipping when under load.
11. Only use the jack on solid ground, preferably concrete. Avoid tarmac as
the jack could sink in.
12. Make sure the load is taken by the full saddle and that the lifting point on
the load is of sufficient strength to support the weight.
13. ALWAYS use axle stands to stabilise the load once lifted.
14. Consult the vehicle handbook to determine the correct lifting points.
15. Ensure the load is chocked and the handbrake applied before lifting.
16. NEVER work on or under a load unless it is fully and adequately supported.
17. NEVER rely upon the jack to hold the load in position.
18. NEVER push a load off the jack.
19. Ensure that all personnel are well clear of a load being raised or lowered.
20. Take care not to trap fingers within the moving parts.
21. Use only as a lifting device, do not use as a dolly to move a load.

OPERATION
POSITIONING
Ensure the vehicle is chocked and stable and on firm level ground.
1. Turn the jack handle counterclockwise, to lower the lifting ram.
2. Position the jack so that the saddle is directly beneath the lifting point and
that there are no obstacles to prevent a clean lift, also, make sure that all
personnel are well away from the area, before raising the vehicle.
LIFTING
1. Close the release valve by turning the jack handle clockwise firmly.
2. Operate the jack by pumping the jack handle.
• Make sure that the saddle is in full contact with the vehicle lifting
point and that there are no obstacles to prevent a clean lift.
3. Place axle stands beneath the vehicle.
• Make sure that the axle stands are centred under the vehicle
support points and are perfectly stable before full weight is taken.
• Make sure that the axle stands are in good condition and capable
of supporting the load.
• Make sure that the axle stands cannot move when supporting the
load and that they are on a firm level surface.
• DO NOT jerk the handle, ensure it lowers slowly and under complete
control on to the axle stands which must be correctly positioned and
take the weight evenly.
NOTE: The jack may move slightly during operation. It is therefore
important that the immediate vicinity is clean and completely
free from clutter.
LOWERING
1. Lift the vehicle slightly to remove the weight from any supports.
2. Remove any supports from beneath the vehicle.
3. Slowly turn the jack handle counterclockwise to open the release valve.
NOTE: make sure that this operation is carried out under complete
control. DO NOT allow the load to drop suddenly as this could
damage internal components.
4. Remove the jack from beneath the vehicle.

MAINTENANCE
1. When the jack is not in use, keep the saddle lowered and the release valve
closed (jack handle turned fully clockwise).
2. Keep the jack clean and apply lubricating oil to all pivoting sections every
three months, or more often when it is used in a dusty work environment.
3. Check the pump piston and piston rod periodically for signs of rust or
corrosion. Clean exposed area with clean oiled cloth.
4. Change the oil once a year or as required, See page 7.
STORAGE
Store in a dry place, with the ram fully retracted. If stored for long periods,
inspect at least once a year, clean and re-oil. For servicing, contact your
CLARKE dealer or CLARKE International Service Department.
