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.

1. Use only as a lifting device, do not use as a dolly to move a load.

UNPACKING AND ASSEMBLY

1. Loosen the thumbscrew in the

yoke until the lower handle can

be inserted fully into the handle

socket.

• The handle has a groove which

should engage with the thumb

screw once it is re-tightened.

• The socket in the handle will

engage with the jack control

valve at the base of the yoke.

2. Tighten the thumb screw to

secure the lower handle to the

jack.

3. Add the upper handle by sliding it

onto the lower handle until the

spring loaded pin clips in place.

Remove the travel retaining block by

pressing the handle yoke downwards

and pulling the block away.

• Take care of pinching fingers

between parts

PURGING AIR FROM THE SYSTEM

If air bubbles become trapped inside

the hydraulic system during shipping

or transport, the efficiency of the jack

will be reduced and the jack will feel

spongy.

1. Use the handle to turn the control

valve anti-clockwise, relieving the

pressure inside the jack.

Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com

2. Pump the handle several times to purge air from the system.

3. Turn the control valve clockwise and test the jack. If efficiency is still low,

check the oil level as described under Maintenance on page 6.

The jack is now ready to use.

OPERATION

This jack incorporates a twin piston pump with a ‘quick lift’ facility. This provides

the user with a rapid raising operation for the unloaded jack. When the jack

reaches the vehicle to be raised its distance raised per stroke reduces to

provide a gradual and controllable lifting operation.

Before use, inspect the jack for oil leaks or any other defect. Should any be

apparent, have the jack repaired by a qualified technician.

1. Ensure the vehicle to be raised is stable and on firm level ground with the

wheels chocked. Ensure the vehicle’s handbrake is on, the engine is

switched off and the transmission is in gear or Park if automatic.

2. Ensure the vehicle will not come into contact with adjacent objects when

tilted by the jacking operation.

3. Position the jack so that the saddle is directly beneath the lifting point.

• Consult the vehicle handbook to determine suitable lifting points.

4. Ensure the jack wheels are free to move and there are no obstructions.

5. Twist the handle clockwise to close the control valve.

6. Pump the handle to raise the saddle until it reaches the jacking point, or

alternatively, pump the handle to raise the saddle.

7. Make sure that the saddle is in full contact with the lifting point and that

there is nothing that will prevent a clean lift. Keep all personnel at a safe

distance before lifting the vehicle.

8. Position suitably rated axle stands directly beneath suitable supporting

points on the vehicle and very gently twist the handle anti-clockwise to

lower the vehicle.

9. Make sure that the axle stands are in good condition and that they can

support the weight of the vehicle.

WARNING: NEVER WORK ON THE VEHICLE WHEN SUPPORTED ONLY BY A

JACK. THIS IS HIGHLY DANGEROUS. THE VEHICLE MUST BE SUPPORTED ON

AXLE STANDS OR SUITABLE SUPPORTS, BENEATH THE CORRECT JACKING/

SUPPORT POINTS.

Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com

10. Ensure that the axle stands cannot move when supporting the load and

are on firm, level ground. Use suitable wheel chocks to stop the vehicle

from moving.

11. The jack may move slightly during operation. It is important therefore, that

the floor is clean and completely free from debris.

12. DO NOT lift the vehicle if there is any chance of spillage of fuel, battery

acid or other liquids.

13. Carefully lower the vehicle onto the axle stand(s), checking constantly that

the vehicle rests snugly and cleanly on the axle stand and that the stand is

stable before the weight is taken.

NOTE: Ensure this is carried out under complete control. DO NOT allow

the load to drop suddenly as this impose undue strain on the jack

internal parts and damage the vehicle.

14. ALWAYS avoid a rapid descent by turning the handle slowly.

15. Completely remove the jack from the vehicle.

MAINTENANCE

CHECKING/TOPPING UP THE OIL LEVEL

If the jack has been stored for long periods, check for oil leaks before use. If

necessary, check the oil level as follows:

1. Ensure the jack is fully lowered by turning the control valve fully anti-

clockwise.

2. Remove the filler plug.

• The oil should be almost level with the bottom of the oil filler hole.

Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com

• Oil can be topped up using CLARKE Hydraulic Oil (p/n 3050830 1 litre).

Never use brake fluid instead of oil.

• Take care not to move the handle while topping up the oil.

3. Replace the filler plug and purge

any air from the system.

4. Wipe up any spillage and dispose

of old or spilled oil appropriately.

GENERAL CARE

1. Periodically lubricate the hinges,

front roller & rear castors with light

oil.

2. In the event of damage or broken

components, replacements are available from CLARKE Parts & Service.

STORAGE

Store in a dry, child-proof place with the ram fully lowered. 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.
