SAFETY PRECAUTIONS

1. This jack is for lifting only, do not move a load using the jack as a dolly.

2. Do not use the jack 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 solid,level base, and that 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 2.)

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 a suitably qualified persons.

15. Do not make any modifications to the jack or adjustments to the valves.

WARNING: THE OPERATOR MUST FOLLOW ALL INSTRUCTIONS WITHIN THIS

INSTRUCTION MANUAL.

BEFORE USE

1. Press down hard enough on the

yoke to overcome the resistance

of the return spring and remove

the packing clip shown.

2. Attach the foot pedal using the

socket-headed bolt as shown.

3. Loosen the nut and pinch bolt just

beside the hole for the handle, to

make it easier to insert the handle

into the socket.

4. Fit the handle into the handle

socket and re-tighten the nut and

pinch bolt, ensuring that the

operating socket of the handle

engages with the square drive

spigot of the control valve.

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 knob

counter-clockwise, relieving the

pressure inside the jack.

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.

4. If efficiency is still poor, check the

oil level as described under

‘Maintenance’.

The jack is now ready to use.

OPERATION

POSITIONING THE JACK

1. Make sure that the load is stable and on firm level ground.

2. Use suitable wheel chocks to stop the vehicle from moving.

3. Turn the knob on the handle counterclockwise to open the release valve.

4. Put the saddle directly below the lifting point of the vehicle (see the vehicle

manufacturers handbook for the locations).

5. Make sure that there is no obstruction that will prevent a clean lift.

6. Ensure that all personnel are in a safe position before you lift the vehicle.

RAISING THE JACK

1. Turn the handle control fully clockwise to close the release valve.

2. Pump the handle so that the saddle rises to the jacking point.

3. Make sure that the saddle is in full contact with the lifting point and that

there is nothing that will prevent a clean lift.

4. Put axle stands below the support points on the vehicle.

5. Make sure that the axle stand is centred below the support point and are

stable before full weight of the vehicle is taken on it.

6. Make sure that the axle stands are in good condition and that they can

hold the load.

7. Ensure that the axle stands cannot move when supporting the load.

8. Make sure to lower slowly and in a controlled manner on to the axle stands.

LOWERING THE JACK

1. Lift the vehicle to remove the weight from axle stands or other supports.

2. Remove the axle stands or other supports from below the vehicle.

3. VERY SLOWLY and CAREFULLY, turn the release valve anticlockwise - as you

do so the jack will lower. To stop it lowering turn the release valve clockwise

again.

NOTE: This operation must be done very slowly and in full control. DO

NOT let the load lower suddenly as this could damage internal

components.

4. Remove the jack from below the vehicle.

MAINTENANCE

GENERAL CARE

1. When the jack is not in use, keep fully lowered and the release valve

closed.

2. Keep the jack clean and occasionally apply lubricating oil to all pivot

points, front wheels & rear castors.

3. Periodically check the oil level.

4. Check the pump piston and piston rod periodically for signs of corrosion.

Clean exposed areas with a clean oiled cloth.

In the event of damage or broken components, replacements are available

from Clarke Parts & Service.

CHECKING/TOPPING UP 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 handle fully

anticlockwise.

2. Loosen the cover securing bolt

and lift off the cover plate.

3. Remove the filler plug, located on

top of the cylinder, using a flat

bladed screwdriver.

• Oil must be level with the

bottom of the filler hole.

4. Top up if necessary with Clarke

hydraulic oil available from your

Clarke dealer (part number

3050830).

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

6. Purge any air from the system and replace the filler plug.

STORAGE

Store in a dry place with the lifting arm fully lowered. If stored for long periods,

inspect at least once a year, clean and re-oil. For servicing, contact your

CLARKE dealer, or CLARKE International Service Department.

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 leakproof 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.
