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.

UNPACKING AND ASSEMBLY

1. Remove the wire retaining clip by

pressing the handle yoke down-

wards and disengaging the clip.

2. Loosen the thumb screw in the

yoke until the lower handle can

be inserted fully into the handle

socket, ensuring the square drive

on the end of the handle,

engages fully with the square

spiggot within the housing.

3. Retighten the locating thumb

screw.

4. Connect the two halves of the

operating handle and secure with

a nut and bolt.

PREPARING FOR USE

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. Turn the control valve counter-clockwise, relieving the pressure inside the

jack.

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

3. Turn the control valve clockwise raise the jack to its full height. Pump the

handle again several full strokes.

4. Test the jack and if efficiency is still low, repeat the above procedure with

the oil filler plug loosened. Check the oil level as described under

Maintenance.

5. The jack is now ready to use.

OPERATION

Before use, inspect the jack for oil leaks or any other sign of damage. 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.

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

• Consult the vehicle handbook to determine suitable lifting points.

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

4. Pump the handle to raise the saddle until it reaches the jacking point.

5. 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.

6. Position axle stands directly beneath suitable supporting points on the

vehicle and very gently twist the handle anti-clockwise.

7. This will open the control valve to lower the load onto the stands.

• Make sure that the axle stands are in good condition and that they

can hold the load.

8. Ensure that the axle stands cannot move when supporting the load. Use

suitable wheel chocks to stop the vehicle from moving.

NOTE: The jack may move slightly during operation. It is important

therefore, that the floor is clean and completely free from debris.

9. To stop it lowering at any point, turn the handle clockwise again. Always

avoid a rapid descent by turning the handle slowly.

10. Carefully lower the vehicle onto the axle stand, checking constantly,

preferably with an assistant, that the vehicles jacking point rests snugly and

cleanly on the axle stand, and that the stand is stable before the weight is

taken.

NOTE: Ensure this operation is carried out under complete control. DO

NOT allow the load to drop suddenly as this could damage

internal parts.

11. Completely remove the jack from 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.

MAINTENANCE

CHECKING / MAINTAINING 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.

• Oil can be topped up using

Clarke Hydraulic Oil (p/n

3050830 1 litre).

3. Purge any air from the system and replace the filler plug.

4. Dispose of old/spilled oil appropriately and wipe up any spillage.

GENERAL CARE

1. Periodically lubricate the hinges, front wheels & rear castors with light oil.

• A grease nipple is provided for the main hinge.

2. Store in a dry location. with the ram fully retracted.

3. In the event of damage or broken components, replacements are

available from CLARKE Parts & Service.

Never throw away used hydraulic oil with domestic refuse or flush it down a

sink or drain. Collect any hydraulic oil in a leak proof container and take it to

your local waste disposal site.

If disposing of this product or any damaged components, do not dispose of

with general waste. This product contains valuable raw materials and should

be taken to your local civic amenity site for recycling of metal products.
