SAFETY PRECAUTIONS
1. Read this 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. 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 retaining clip by pressing
the handle yoke down-wards and
pulling the clip away.
2. Loosen the thumb screw in the yoke
until the lower handle can be inserted
fully into the handle socket.
• The lower handle has a groove
which should engage with the
thumb screw once it is retightened.
• The socket in the handle will engage with the jack control valve at the base
of the yoke.
3. Tighten the thumb screw to secure
the lower handle to the jack.
4. Add the upper handle onto the lower
handle using the bolt/nut supplied.
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. Insert the handle into the yoke and
twist the control valve counterclockwise, relieving the pressure
inside the jack, then remove the
cover plate.
2. Remove the filler plug and 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.
4. 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 encounters a
load (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 sign of damage. Should any be
apparent, have the jack repaired by a qualified technician.
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.
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. AXLE STAND MUST BE ON A
FIRM, LEVEL SURFACE.
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 under the vehicle.
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 anticlockwise.
2. Remove the retaining screws and lift
off the cover plate.
3. 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).
4. Purge any air from the system and replace the filler plug and cover plate.
5. 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.
2. Store in a dry location.
3. In the event of damage or broken components, replacements are available from
Clarke Parts & Service.
ENVIRONMENTAL PROTECTION
One of the most damaging sources of environmental pollution is oil products. 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.
