using this jack.
OPERATION
1. Ensure the vehicle is securely supported.
2. Ensure there are no personnel or obstructions under the vehicle before
lowering.
3. Ensure when lifting, that the jack and all parts of the load can be clearly
seen. Always watch the jack and the load during operation.

4. Never climb on, or attempt to ride on the jack.
5. Take care not to trap fingers in the moving parts of the jack.
6. Ensure that you can see the contact and jacking point throughout the
jacking operation in case there is any relative movement.
7. This jack is for lifting only, do not move a load using the jack as a dolly.
8. Make sure the load is taken by the full surface of thecylinder or nose, and
that the point of lift on the load is strong enough to support the load
adequately.
9. Consult the vehicle handbook to determine the correct lifting points.
10. 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.
11. Never push a load off the jack.
LIFTING OPERATIONS AND LIFTING EQUIPMENT REGULATIONS 1998
This jack, depending on use, may fall within the scope of LOLER. It is the
owner’s responsibility to determine whether or not it does, and if so, to comply
with any applicable requirements. It may be necessary to have the jack
regularly inspected.
ENVIRONMENTAL PROTECTION
1. Take care to ensure that any spilt hydraulic oil is cleaned away using sand,
or treated with absorbent granules designed for the purpose.
2. Always make every effort to contain any spillage and prevent ingress into
the local water course.

BEFORE USE
FIT THE HANDLE
1. Insert the lower handle into the
handle socket and tighten the
locking bolt shown to secure the
handle in position.
2. Add the upper handle section
and secure with the bolt shown.
CHECK THE OIL LEVEL
1. Remove the filler plug and check
the oil level.
• Oil should be up to the edge of
the filler hole.
2. Top up if necessary with Clarke
hydraulic oil available from your
local Clarke dealer (part number
3050830).
• Oil grade SAE10, capacity
480ml.
PURGE AIR BUBBLES
During shipment, air bubbles can occur in the hydraulic system which will
cause the jack to feel “spongy” and it may not achieve its maximum lift.
1. Pump the operating handle several times to purge any air from the
hydraulic system.
2. Twist the handle counterclockwise to open the release valve and lower the
jack. Check that the jack descends to its lowest position.
• The jack is now ready to use.

OPERATION
RAISING A LOAD
WARNING: BEFORE LIFTING, ENSURE THE SAFETY PRECAUTIONS ARE
STRICTLY FOLLOWED. NO RESPONSIBILITY CAN BE ACCEPTED FOR
INCORRECT USE OF THE JACK.
WARNING: PLEASE NOTE THAT THE SCISSOR ACTION OF THE JACK WILL
CAUSE THE JACK TO MOVE SLIGHTLY AS IT IS RAISED AND LOWERED. IT IS
MOST IMPORTANT THAT THIS MOVEMENT IS NOT RESTRICTED IN ANY WAY.
ENSURE THE GROUND IN THE IMMEDIATE VICINITY OF THE JACK IS FREE
FROM DEBRIS.
1. Before use, check for any damage or worn parts. Do not use the jack
unless it is perfectly serviceable.
2. Ensure the load is chocked and stable, and on firm level ground, before
manoeuvring the jack so that the grooves in the nose or the top of the
cylinder, (whichever is to be used), is directly beneath the lifting point of the
load.
3. Twist the handle clockwise to close the release valve.
4. Put the nose directly below the lifting point of the vehicle (see the
manufacturers handbook for the best locations).
• Make sure that there is no obstruction that will prevent a clear lift
and that all personnel are in a safe position before you lift the
vehicle.
5. Pump the handle to raise the jack until contact is made with the lifting
point.
6. Make one final check to ensure that there are no obstructions to lifting and
that all personnel are well clear before continuing to pump the handle and
lift the load.
7. NEVER allow any individual to get beneath the load until it is firmly chocked
or supported on axle stands or similar supports.
LOWERING THE LOAD
1. With the axle stands/supports removed, check to ensure that there are no
personnel in the immediate vicinity before VERY SLOWLY twisting the lifting
handle anticlockwise and allowing the jack to lower the load.
NOTE: This operation must be done very slowly and in full control. DO
NOT let the load lower suddenly, this could damage internal
components.
6
2. Remove the jack from below the vehicle.
NOTE: The jack can move slightly during operation. It is important that
the area is clean and free from all debris.
MAINTENANCE
1. Remove any corrosion and repaint for protection.
2. Check the piston rod periodically for signs of corrosion. Clean exposed
areas with a clean oiled cloth.
3. Ensure that labels and warning notices are in place and legible.
4. Inspect for distortion of hinge pins and security of all nuts and bolts.
5. Keep all moving parts lightly lubricated to prevent any possibility of
corrosion.
• A grease nipple is provided for occasional lubrication of the main
supporting axle.
6. If an oil leak is seen, check the oil level as described on page 5.
7. In the case of a persistant oil leak which requires the dismantling of the
hydraulic parts to correct, the jack should be taken to your Clarke dealer
for overhaul.
STORAGE
Store in a dry place with the ram fully lowered and the release valve closed.
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.
