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 than 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 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
tarmacadam 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

BEFORE USE
UNPACKING AND ASSEMBLY
1. Remove the retaining clip by
pressing the yoke downwards and
pulling the clip away.
• The yoke can now hinge up
and down freely.
2. Insert the jack handle into the
handle socket.
• The handle will engage with
the jack control valve at the
base of the yoke.
3. Tighten the retaining bolt if
required to retain the handle in
the jack.
4. Add the upper handle by sliding it
onto the lower handle until the
spring loaded pin clips into 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. Turn the control handle counter-clockwise, relieving the pressure inside the
jack.
2. Pump the handle several times to purge air from the system.
3. Turn the control handle clockwise and test the jack. If efficiency is still poor,
check the oil level as described under Maintenance on p7.
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 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. 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.
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.
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.

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
GENERAL CARE
1. When the jack is not in use, keep the ram fully lowered and the release
valve closed.
2. Keep the jack clean and occasionally apply lubricating oil to all pivot
points, front wheels & rear castors.
3. Periodically check the oil level as follows.
4. Check the pump piston and piston rod periodically for signs of corrosion.
Clean exposed areas with a clean oiled cloth.
5. In the event of damage or broken components, replacements are
available from CLARKE Parts & Service.
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. Lift away the plastic tray and
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 oil.
3. Purge any air from the system and replace the filler plug.
4. Dispose of old/spilled oil appropriately and wipe up any spillage.
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.
