SAFETY PRECAUTIONS
1. This jack is for lifting only, do not move a load using the jack as a dolly.
2. Do not use to lift people.
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. Make sure that the jack is on a firm level base, and there is no possibility of
it slipping when under load.
5. 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.
6. 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.
7. Never push a load off the jack.
8. Ensure that all personnel are well clear of a load being raised or lowered.
9. Do not try to lift more then the rated load for the jack.
10. Do not use the jack if an oil leak is apparent. Consult your Clarke dealer.

UNPACKING AND ASSEMBLY
1. Connect the two halves of the
Operating Handle and secure
with a nut and bolt.
2. Remove the packing wedge
shown in fig. 2.
3. Remove the locating screw from
the rear of the handle housing,
shown in Fig 3 and insert the
handle into the housing, ensuring
the square drive on the end of the
handle, engages fully with the
square spigot within the housing.
4. Replace and tighten the locating
screw.
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.

5
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.

• 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.

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