SAFETY PRECAUTIONS
GENERAL
1. ALWAYS read and ensure you fully understand the following precautions
and the hazards associated with this product. Do not allow anyone who
has not read these instructions to use the jack.
2. Only use this jack for its intended purpose.
3. NEVER carry out any modifications to this product. If experiencing difficulty
of any kind consult your local dealer.
WORK AREA
1. NEVER use the jack on sloping surfaces, only on level ground. The jack may
move away slightly as soon as it lifts the tyre from the ground.
2. DO NOT start the vehicle engine with the jack in use.
3. This jack is for lifting only. DO NOT move a load using the jack as a dolly.
4. Ensure the load is taken by the full saddle and that the point of lift on the
load is of sufficient strength to support the full load adequately.
5. Never allow children or bystanders in the area while the jack is in use.
6. NEVER work under a vehicle supported only by this jack. If working
underneath a vehicle. Always use axle stands designed for the purpose.
7. Ensure the jack is on a firm solid base and that there is no likelihood of it
slipping, sinking or otherwise moving when under load.
8. Ensure that all personnel are well clear of a load being raised or lowered.
SERVICING & REPAIRS
1. Check the jack for damage before use and do not use if damaged. If in
doubt, DO NOT use. Consult your local dealer.
2. ALWAYS use spare parts supplied by Clarke International. Using non-
standard parts could be extremely dangerous.
3. Ensure that the jack is properly maintained at all times and that no
corrosion or other damage is allowed to weaken any part of it.
4. When necessary, have your jack serviced or repaired by a qualified
technician using identical replacement parts. This will ensure that the
WARNING: THE OPERATOR MUST FOLLOW ALL INSTRUCTIONS WITHIN THIS
INSTRUCTION BOOKLET

4
safety of the jack is maintained.
5. NEVER use the jack if it has been subjected to excess load (over 1.5
tonnes). The jack should be removed from service immediately and fully
inspected by qualified personnel and passed as serviceable before further
use.
Please keep these instructions in a safe place for future reference
UNPACKING AND ASSEMBLY
1. Remove the socket headed
screw from the handle.
2. Insert the handle fully into the
handle yoke until it engages with
the jack control valve at the base
of the yoke.
3. Re-fit the socket headed screw to
secure the handle to the jack.
OPERATION
This jack incorporates a twin piston pump with a ‘quick lift’ facility. This provides
the user with a rapid raising operation for the unladen 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. 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. Turn the control valve release knob clockwise to close the valve.
4. Pump either the foot pedal or the handle to raise the saddle until it reaches
the vehicle lifting point.
WARNING: NEVER WORK ON THE VEHICLE WHEN SUPPORTED ONLY BY A
JACK. THIS IS A HIGHLY DANGEROUS PRACTICE. THE VEHICLE MUST BE
SUPPORTED ON AXLE STANDS OR SUITABLE SUPPORTS, BENEATH THE
CORRECT JACKING/SUPPORT POINTS.

5
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 free
from debris.
6. Position axle stands directly
beneath suitable supporting points on the vehicle, and very gently twist the
control valve release knob anticlockwise.
• This will open the control valve to lower the load onto the stands.
7. To stop the jack lowering at any point, turn the release knob clockwise
again. Always avoid a rapid descent by turning the valve control slowly.
8. Carefully lower the vehicle onto the axle stand, checking constantly,
preferably with an assistant, that the vehicles supporting point rests snugly
and cleanly on the stand, and that the supporting stand is stable before all
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 during shipping
or transport, the efficiency of the jack
will be reduced and the jack will feel
spongy. Air can be purged from the
system as follows.
1. Turn the control handle counter-
clockwise, relieving the pressure
inside the jack, then remove the
cover plate and oil filler plug.
• A broad-bladed screwdriver is required for the plug.
2. Pump the handle several times to purge air from the system.

6
3. Replace the oil filler plug, then turn the control valve release knob
clockwise and test the jack. If efficiency is still low, check the oil level as
below.
CHECKING 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 release knob
fully 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.
• Oil 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 old oil appropriately and be sure to 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 nipple on the
top of the lifting arm.
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.
