SAFETY PRECAUTIONS
1. Only trained persons should operate this lifting equipment.
2. ALWAYS ensure that sufficient light is provided and that the work area is
kept clear of unrelated items.
3. 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.
4. The jack must be maintained and repaired by suitably qualified persons.
5. DO NOT make any modifications to this jack or adjust any valves.
6. DO NOT use the jack if an oil leak is apparent. Consult your CLARKE dealer.
7. DO NOT try to lift more then the 3 Tonne rated load for the jack.
8. This jack is for lifting only; do not move a load using the jack as a dolly.
9. DO NOT use to lift people and ensure that no-one is in the vehicle during
lifting.
10. Make sure that the jack is on a firm level base 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 point of lift on
the load is strong enough to support the load adequately.
13. DO NOT work under the raised vehicle until it is supported by suitable
means e.g. axle stands. NEVER rely on the jack to support the vehicle by
itself.
14. NEVER push a load off the jack.
15. Ensure that all personnel are well clear of a load being raised or lowered.
16. Consult the vehicle handbook to determine the correct lifting points.
17. It is necessary that the operator watch both the jack and the load during
operation.
18. Check the condition of the labels regularly and replace if required.
WARNING: THE OPERATOR MUST FOLLOW ALL INSTRUCTIONS WITHIN THIS
INSTRUCTION BOOKLET

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. Remove the travel block by
pressing the handle yoke down-
wards and pulling the block
away.
3. Tighten the thumb screw to
secure the lower handle to the
jack.
4. Add the upper handle by sliding it
onto the lower handle until the
spring loaded pin clips in place.
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.

5
Parts & Service: 020 8988 7400 / E-mail: [e-mail] or Se[email protected]
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.
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
reaches the vehicle to be raised, its lift 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 pedal to raise the saddle.
IMPORTANT: The foot pedal is used to quickly bring the saddle to the lifting
point, NOT to raise a load.
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: [e-mail] or Servi[email protected]
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 four 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). Never use
brake fluid or instead of
hydraulic oil.
• Take care not to move the handle while filling with oil.
4. Replace the filler plug and cover plate and purge any air from the system
(see page 4).
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.
