ALWAYS ensure that sufficient light is provided and that the work area is kept clear of unrelated items. 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. The jack must be maintained and repaired by suitably qualified persons. 5. DO NOT make any modifications to this jack or adjust any valves. 6. DO NOT use the jack if an oil leak is apparent. Consult your CLARKE dealer. 7. DO NOT try to lift more then the rated load for the jack. 8. This jack is for lifting only; do not move a load using the jack as a dolly. 9. DO NOT use to lift people and ensure that no-one is in the vehicle during lifting. 10.Make sure that the jack is on a firm level base and there is no possibility of it slipping when under load. 11. Only use the jack on solid ground, preferably concrete. Avoid tarmac as the jack could sink in. 12. 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. 13. 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. 14.NEVER push a load off the jack. 15. Ensure that all personnel are well clear of a load being raised or lowered. 16. Consult the vehicle handbook to determine the correct lifting points. 17. It is necessary that the operator watch both the jack and the load during operation. 18. Check the condition of the labels regularly and replace if required. WARNING: THE OPERATOR MUST FOLLOW ALL INSTRUCTIONS WITHIN THIS INSTRUCTION BOOKLET
Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com UNPACKING AND ASSEMBLY 1. Loosen the thumbscrew in the yoke until the lower handle can be inserted fully into the handle socket.
- The 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. 2. Remove the travel block by pressing the handle yoke down-wards and pulling the block away. 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 until the spring loaded pin clips in place. PURGING AIR 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. Use the handle to turn the control valve anti-clockwise, relieving the pressure inside the jack. 2. Pump the handle several times to purge air from the system.
Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com 3. Turn the control valve clockwise and test the jack. If efficiency is still low, check the oil level as described under Maintenance on page 6. 4. The jack is now ready to use. 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 reaches the vehicle to be raised, its lift per stroke reduces, to provide a gradual and controllable lifting operation. Before use, inspect the jack for oil leaks or any other defect. 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. Ensure the vehicle’s handbrake is on, the engine is switched off and the transmission is in gear or park if automatic. 2. Ensure the vehicle will not come into contact with adjacent objects when tilted by the jacking operation. 3. Position the jack so that the saddle is directly beneath the lifting point.
- Consult the vehicle handbook to determine suitable lifting points. 4. Ensure the jack wheels are free to move and there are no obstructions. 5. Twist the handle clockwise to close the control valve. 6. Pump the handle to raise the saddle until it reaches the jacking point, or alternatively, pump the pedal to raise the saddle. IMPORTANT: The foot pedal is used to quickly bring the saddle to the lifting point, NOT to raise a load. 7. 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. 8. Position suitably rated axle stands directly beneath suitable supporting points on the vehicle and very gently twist the handle anti-clockwise to lower the vehicle. 9. Make sure that the axle stands are in good condition and that they can support the weight of the vehicle. 10. 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. 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.

It is important therefore, that the floor is clean and completely free from debris. 12.DO NOT lift the vehicle if there is any chance of spillage of fuel, battery acid or other liquids. 13. Carefully lower the vehicle onto the axle stand(s), checking constantly that the vehicle rests snugly and cleanly on the axle stand and that the stand is stable before the weight is taken. NOTE:Ensure this is carried out under complete control. DO NOT allow the load to drop suddenly as this impose undue strain on the jack internal parts and damage the vehicle. 14.ALWAYS avoid a rapid descent by turning the handle slowly. 15. Completely remove the jack from the vehicle. SUITABLE AXLE STANDS FOR USE WITH THIS JACK

If necessary, check the oil level as follows: 1. Ensure the jack is fully lowered by turning the control valve fully anti- clockwise. 2. Remove the four retaining screws and lift off the cover plate.
Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com 3. 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). Never use brake fluid or instead of hydraulic oil.
- Take care not to move the handle while filling with oil. 4. Replace the filler plug and cover plate and purge any air from the system (see page 4). 5. Dispose of old/spilled oil appropriately and wipe up any spillage. GENERAL CARE 1. Periodically lubricate the hinges, front wheels & rear castors with light oil. 2. Store in a dry location. 3. In the event of damage or broken components, replacements are available from CLARKE Parts & Service.
