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, (See “Specifications”

on page 3.)

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. It is necessary that the operator 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 adjustment any valves.

WARNING: THE OPERATOR MUST FOLLOW ALL INSTRUCTIONS WITHIN THIS

INSTRUCTION BOOKLET

UNPACKING AND ASSEMBLY

1. Remove the retaining clip by

pressing the handle yoke down-

wards and pulling the clip away.

2. Loosen the thumb screw in the

yoke until the lower handle can

be inserted fully into the handle

socket.

• The lower 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.

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 and secure

with the bolt provided.

5. Place the protective rubber pad

onto the saddle.

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.

1. Turn the control valve counter-

clockwise, relieving the pressure

inside the jack, then remove the

cover plate.

2. Pump the handle several times to

purge air from the system, while pressing down on the filler plug when the

air is expelled.

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

check the oil level as described under Maintenance.

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

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. Twist the handle clockwise to close the control valve.

4. Pump the handle to raise the saddle until it reaches the jacking point.

5. 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.

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. Position axle stands directly beneath suitable supporting points on the

vehicle and very gently twist the handle anti-clockwise.

7. This will open the control valve to lower the load onto the stands.

• Make sure that the axle stands are in good condition and that they

can hold the load.

8. Ensure that the axle stands cannot move when supporting the load. Use

suitable wheel chocks to stop the vehicle from moving.

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

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

9. To stop it lowering at any point, turn the handle clockwise again. Always

avoid a rapid descent by turning the handle slowly.

10. Carefully lower the vehicle onto the axle stand, checking constantly,

preferably with an assistant, that the vehicles jacking point rests snugly and

cleanly on the axle stand, and that the stand is stable before 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.

11. Completely remove the jack from the vehicle.

MAINTENANCE

CHECKING /MAINTAINING 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 fully anti-

clockwise.

2. Remove the retaining screws and

lift off the cover plate.

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).

4. Purge any air from the system and replace the filler plug and cover plate.

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.

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.
