GENERAL SAFETY PRECAUTIONS
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 underneath a vehicle supported only by this product. If
working under 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 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 the jack is properly maintained at all times and that no damage is
allowed to weaken any part of it. Do not use if an oil leak is apparent.
4. When necessary, have your jack serviced or repaired by a qualified
technician using identical replacement parts. This will ensure that the safety
of the jack is maintained
5. NEVER exceed the rated load or use the jack if it has been subjected to
excess load (over 2.25 tonne). 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

OPERATION
Before use, visually inspect the jack for oil leaks or any other sign of damage.
Should any be apparent, have the jack inspected and repaired by a qualified
technician before use.
The CTJ2250LP trolley jack is equipped with an operating handle which can
also be used as a wheel brace, in conjunction with the double-ended sockets
carried in the socket holder..
1. Ensure the vehicle to be raised is stable
and on firm level ground with the
supporting 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.
Engage the handle with the
control valve shown in Fig 1and
turn it clockwise to close the valve
4. Insert the handle into the handle
sleeve and pump the handle to
raise the saddle until it reaches
the vehicle lifting point.
NOTE: The control valve is able to
rotate through 360 deg as
shown in Fig 2, & can
therefore be operated from any position.
5. Take care that there are no
obstructions to prevent a clean
lift. Keep all personnel at a safe
distance before continuing to
pump the handle to raise the
vehicle.
NOTE: 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 A HIGHLY DANGEROUS PRACTICE. THE VEHICLE MUST BE
SUPPORTED ON AXLE STANDS, OR SUITABLE SUPPORTS, BENEATH THE
JACKING/SUPPORT POINTS RECOMMENDED BY THE VEHICLE
MANUFACTURER. THERE SHOULD BE NO LOAD ON THE JACK.
5
6. Position axle stands directly beneath suitable supporting points below the
vehicle, before engaging the handle with the control valve and very
gently twisting the handle anticlockwise.
• This will open the control valve to lower the load onto the stands.
7. To stop it lowering, 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 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, the efficiency of
the jack will be reduced. Any air can be purged from the system as follows.
1. Turn the control valve counter-clockwise and remove the filler plug.
2. Pump the handle several times to purge air from the system.
3. Replace the filler plug, then turn the control valve 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 using the handle to turn the control valve
fully anticlockwise.
2. Lift up the cover plate and remove the oil filler plug on the top of the ram
assembly. A large cross headed screwdriver is required.
• The oil should be almost level with the bottom of the oil filler hole.
• Top up using Clarke Hydraulic Oil (p/n 3050830 for 1 litre).
OIL REPLACEMENT
1. With the jack lowered, remove the filler plug. Tilt the jack onto its side and
drain the old oil into a container.
6
2. Return the jack to upright and refill with hydraulic oil up to the lower rim of
the filler hole.
3. Purge any air from the system and replace the 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.
2. Store in a dry location with the arm in its lowest position.
3. In the event of damage or broken components, replacements are
available from Clarke Parts & Service.
