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 level base, and 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 then the rated load for the jack.

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. Always 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 by suitably qualified persons.

15. Do not make any modifications to this jack or adjust any valves.

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.

WARNING: THE OPERATOR MUST FOLLOW ALL INSTRUCTIONS WITHIN THIS

INSTRUCTION BOOKLET

BEFORE USE

1. Before use, attach the lifting

handle by clipping it over the two

large nuts at the main arm pivot.

2. Inspect the jack for oil leaks or any

sign of damage. If in doubt, do

not use. Should any defects be

apparent, have the jack repaired

by your CLARKE dealer.

3. Check the piston for dirt, rust etc

which can damage the piston

and internal components.

The jack is now ready to use.

OPERATION

1. Ensure the vehicle to be raised is stable and on firm level ground with the

wheels chocked.

NOTE: The jack may move slightly during operation. It is important

therefore, that the floor is clean and completely free from debris.

2. Position the jack so that the

saddle is directly beneath the

lifting point.

• Consult the vehicle handbook

to determine the lifting points.

3. Place the operating lever over the

release valve and turn it fully

clockwise to close the valve.

4. Place the operating lever in the

jacking port and pump the

operating lever so that the saddle rises to the lifting point.

5. Check that there are no obstacles to prevent a clean lift, also, make sure

that all personnel are well away from the area, before raising the vehicle.

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.

6. Pump the handle to raise the vehicle to the required level.

• If, at any time, the jack feels spongy, follow the bleeding procedure

under Maintenance.

7. Position suitable, good quality axle stands directly beneath the supporting

points on the vehicle. Place the operating lever over the release valve and

very gently twist the operating lever anti-clockwise to lower the load onto

the stands.

8. Check constantly, preferably with an assistant, that the vehicle is resting

correctly on the axle stands and that the stands are stable before the

weight is taken.

9. Place the operating lever over the release valve and VERY slowly turn the

handle anti-clockwise to lower the load on to the axle stands.

• Ensure the axle stands are centred about the support point and

perfectly stable before full weight is taken.

10. To stop it lowering at any point, turn the operating lever clockwise again.

Always avoid a rapid descent by turning the operating lever slowly.

NOTE: Ensure this is carried out under complete control. DO NOT allow

the load to drop suddenly as this could damage internal parts.

11. Completely remove the jack from the vehicle.

MAINTENANCE

CHECKING/MAINTAINING THE OIL LEVEL

1. Ensure the jack is fully lowered by

turning the control valve fully anti-

clockwise.

2. Remove the filler plug.

• The oil should be almost level

with the bottom of the filler hole

• Oil can be topped up using

Clarke Hydraulic Oil (p/n

3050830 1 litre).

3. Bleed any air from the system as described on page 6 and replace the filler

plug and cover plate.

4. Dispose of old/spilled oil appropriately and wipe up any spillage.

BLEEDING AIR FROM THE SYSTEM

1. Use the operating lever to turn the release valve anti-clockwise, relieving

pressure inside the jack.

2. Pump the operating lever several times to purge air from the system.

3. Turn the release valve clockwise and test the jack. If efficiency is still low,

check the oil level as described above.

4. Wipe up any oil spillage and dispose of old/spilled oil appropriately.
