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, solid, level base, and that 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 than the rated load for the jack, (See “Specifications”
on page 3.)
10. Do not use the jack if an oil leak is apparent. Consult your Clarke dealer.
11. Consult the vehicle handbook to determine the correct lifting points.
12. It is necessary that the operator watch the jack and the load during
operation.
13. Check the condition of the labels regularly and replace as required.
14. The jack must be maintained and repaired in accordance with the these
instructions and such work be carried out by qualified persons.
15. Do not make any adjustments to any valves on the jack.
WARNING: THE OPERATOR MUST FOLLOW ALL INSTRUCTIONS WITHIN THIS
INSTRUCTION BOOKLET

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 re-
tightened.
• 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 by sliding it
onto the lower handle and secure
with the bolt provided.
5. Place the protective rubber pad
onto the saddle.

6
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, while
pressing down on the filler plug when the air is expelled.
3. Turn the control handle clockwise and test the jack. If efficiency is still poor,
check the oil level as described under Maintenance.
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.
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.
5. Position axle stands directly beneath suitable supporting points on the
vehicle and very gently twist the handle anti-clockwise.
6. 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.
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.

7
7. 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.
NOTE: The jack may move slightly during operation. It is important
therefore, that the floor is clean and completely free from debris.
8. To stop it lowering at any point, turn the handle clockwise again. Always
avoid a rapid descent by turning the handle slowly.
9. 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.
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 /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.

8
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.
STORAGE
1. Store in a dry place with the ram fully lowered. If stored for long periods,
inspect at least once a year, clean and re-oil. For servicing, contact your
CLARKE dealer, or CLARKE International Service Department.
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.
