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 fo r 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 sl oping 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 sa ddle 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 sup ported 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 clea r 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
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 stab le 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. Engage the handle with the control valve shown in Fig 1and tur n it clockwise to close the valve 4. Insert the handle into the handle slee ve and pump the handle to raise the saddle until it reaches the vehicle lifting point. NOTE: T he control valve is able to rotate through 360 deg as shown in Fig 2, & can therefore be operated from any position. 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.
- Position axle stands directly bene ath 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 th e 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 usin g 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 wi th 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.
- Return the jack to upright and refill wi th 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 an d be sure to wipe up any spillage. GENERAL CARE 1. Periodically lubricate th e 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. TROUBLESHOOTING If any of these remedies fail to restore your jack, consult your Clarke dealer.

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 all the hydraulic oil in a leak proof container and take it to your local waste disposal site
