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 2.)
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 bolt 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
bolt 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 bolt 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.
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.
1. 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.
WARNING: NEVER WORK ON THE VEHICLE WHEN SUPPORTED ONLY BY A
JACK WHICH IS A HIGHLY DANGEROUS PRACTICE. THE VEHICLE MUST BE
SUPPORTED ON AXLE STANDS OR SUITABLE SUPPORTS, BENEATH THE
CORRECT JACKING/SUPPORT POINTS.

5
4. Pump the handle to raise the saddle until it reaches the jacking point.
5. Take care that no obstruction prevents a clean lift. Keep all personnel at a
safe distance before lifting the vehicle.
NOTE: The jack may move slightly during operation. It is important
therefore, that the floor is clean and completely free from debris.
6. Position axle stands directly beneath suitable supporting points on the
vehicle and very gently twist the handle anticlockwise.
• This will open the control valve to lower the load onto the stands.
7. To stop it lowering at any point, turn the handle clockwise again. Always
avoid a rapid descent by turning the handle slowly.
8. 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.
9. Completely remove the jack from the vehicle.
MAINTENANCE
PURGING AIR FROM THE SYSTEM
If air bubbles become trapped inside
the hydraulic system, the efficiency
of the jack will be reduced. If the air
cannot be dispersed just by pumping
the handle with the valve open, it
can be purged from the system as
follows.
1. Turn the control valve counter-
clockwise, relieving the pressure
within the jack, then remove the
cover plate & oil filler plug.
• A broad-bladed screwdriver is required for the plug.
2. Pump the handle several times to purge air from the system.
3. Replace the oil filler plug, then turn the control valve clockwise and test the
jack. If efficiency is still low, check the oil level as below.

6
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 anticlockwise.
2. Remove the cover plate and the oil filler plug.
• The oil should be almost level with the bottom of the oil filler hole.
• il can be topped up using Clarke Hydraulic Oil (p/no 3050830 for 1
litre).
3. Purge any air from the system and replace the oil filler plug.
4. Dispose of any old/spilled oil appropriately and wipe up any spillage.
GENERAL CARE
1. Periodically lubricate the hinges, front wheels & rear castors with light oil.
Should the arm become stiff, apply a shot of grease to the grease nipple
on the top of the lifting arm as shown above.
2. Store in a dry location.
3. In the event of damage or broken components, replacements are
available from Clarke Parts & Service.
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.
