SAFETY PRECAUTIONS
1. This jack is for lifting only, do not move a load using the jack as a dolly.
2. 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 parts replaced or consult your
CLARKE dealer.
3. Make sure that the jack is on a firm solid base, and there is no possibility of it
slipping when under load.
4. Make sure the load is taken by the full saddle and that the point of lift on
the load, is of sufficient strength to support the full load adequately.
5. Always use axle stands to stabilise the load once lifted. NEVER work on or under
a load unless it is fully and adequately supported. NEVER rely upon the jack to
hold the load in position.
6. Never push a load off the jack.
7. Ensure that all personnel are well clear of a load being raised, or lowered.
8. NEVER exceed the rated load for the jack (See “Specifications” on
page 3.).
9. Do not use if an oil leak is apparent. Consult your Clarke dealer.
10. Consult the vehicle handbook to determine the correct lifting points.

LUBRICATE INTERNAL COMPONENTS
1. Open the release knob.
2. Pump the handle several strokes to assure proper internal lubrication.
BLEED HYDRAULIC SYSTEM
During transportation, the jack may become "air-bound" causing spongy ram
action.
TO BLEED THE HYDRAULIC SYSTEM -
1. Close the release valve by turning
release knob clockwise.
2. Remove the 4 cover screws and
lift off the cover.
3. Remove the transport plug.

up to full height,

OPERATION
POSITIONING
Ensure the load is chocked and stable and on firm level ground.
1. Release the handle lock as shown on the right.
2. Turn the release knob counterclockwise, to lower
the lifting ram
3. Position the jack so that the saddle is directly
beneath the lifting point and 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.
TO LIFT
1. Close the release valve by turning the release knob clockwise firmly.
2. Operate the jack by pumping the jack handle or foot pedal
• Make sure that the saddle is in full contact with the lifting point and that
there are no obstacles to prevent a clean lift.
3. Place axle stands beneath the vehicle.
• Ensure the axle stands are centred about the support point and
perfectly stable before full weight is taken.
• Ensure that the axle stands are in good condition and fully capable of
supporting the load.
• Ensure that the axle stands cannot move when supporting the load.
• DO NOT jerk the handle, ensure it lowers slowly and under complete
control on to the axle stands which must be correctly positioned and
take the weight evenly.
TO LOWER
1. Lift the vehicle slightly to remove the weight from any supports,
2. Remove any supports from beneath the vehicle.
3. Open the release valve by SLOWLY turning the release knob counterclockwise.
NOTE: Ensure this operation is carried out under complete control. DO
NOT allow the load to drop suddenly as this could damage
internal components.
4. Remove the jack from beneath the vehicle.
NOTE: The jack may move slightly during operation. It is important
therefore that the immediate vicinity is clean and completely
free from debris.
