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 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. Press down on the actuating yoke
in order to remove the packing
block used to position the yoke
during shipping.
2. If the jack has not been recently
used inspect it for oil leaks or any
other sign of damage. If in doubt,
do not use. Should any defects be
apparent, return the jack to your
Clarke dealer.
3. Install the lower operating handle
by loosening the securing bolt
and sliding the handle into the
actuating yoke as far as it will go.
Re-tighten the securing bolt.
4. Add the upper operating handle
which is held to the lower handle
by a spring loaded plunger.

OPERATION
1. Ensure the vehicle to be raised is stable and on firm level ground with the
wheels chocked.
• 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
under the vehicle.
• Consult the vehicle handbook to determine the lifting points.
3. Use the operating handle to close the release valve by turning it fully
clockwise.
4. Pump the operating lever to raise the saddle to the jacking point.
5. Check that there are no obstructions to prevent a clean lift and make sure
all personnel are well clear before raising the vehicle.
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.
• Ensure the axle stands are centred under the support point and fully
stable before full weight is taken.
9. To stop it lowering at any point, turn the operating valve clockwise again.
Always avoid a rapid descent by turning slowly.
NOTE: Ensure this is carried out under complete control. DO NOT allow
the load to drop suddenly as this could damage internal parts.
10. Completely remove the jack from 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.

MAINTENANCE
CHECKING/MAINTAINING THE OIL LEVEL
1. Inspect the hydraulic parts of the
jack for signs of oil leaks. If the oil
needs topping up proceed as
follows.
2. Ensure the jack is fully lowered by
turning the control valve fully anti-
clockwise.
3. Remove the cover plate and the
oil filler plug.
• The oil should be almost level
with the bottom of the filler hole.
• Oil can be topped up using Clarke Hydraulic Oil (Part number
3050830 -1 litre).
4. Bleed any air from the system as described below and replace the filler
plug and cover plate.
5. Dispose of old/spilled oil appropriately and wipe up any spillage. 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.
6. If movement of the main arm becomes sluggish a couple of shots of
grease to the grease nipple will be beneficial.
BLEEDING AIR FROM THE HYDRAULIC RAM
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 hydraulic ram.
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.
STORAGE
1. Store in a dry place with the ram fully retracted, where it cannot be
damaged by moisture. If stored for long periods, clean any grime from the
piston area before use.
