SAFETY PRECAUTIONS
1. Do not exceed the rated capacity of the jack.
2. Do not let anyone operate the jack unless they have read these safety
precautions.
3. Do not operate the jack if damaged in any way.
4. Use the jack in a well lit work area.
5. Keep the work area clean and tidy and free from unrelated items.
6. Only use the jack on level and solid ground, preferably concrete. Never
use it on soft/unmade ground as the jack may sink in.
7. Make sure that non-essential persons keep a safe distance whilst the jack is
in use.
8. Make sure there are no people or obstructions under the vehicle before
lowering.
9. Do not work below the vehicle until it is fully supported by axle stands.
10. Keep your hands clear of the vehicle until lifting is complete.
11. Make sure that you can see the saddle and jacking point throughout the
jacking operation in case there is any relative movement.
12. Always make sure that the jack saddle is centred and stable on the lifting
point before lifting and position the jack to avoid operating it from under
the vehicle.
13. Check the vehicle weight and location of the lifting points by referring to
the vehicle owners manual.
14. Do not tamper with the jack or modify it in any way, as this could prove to
be dangerous and will invalidate the guarantee.
15. Only use the jack for the purpose for which it is intended.
16. Use applicable safety equipment, such as protective footwear, when you
use this jack.
17. Make sure that the jack is correctly maintained and lubricated at all times,
and that no corrosion is allowed to weaken any part of it.
18. If the jack has been subjected to an abnormal load or shock, it should be
removed from service immediately and fully inspected by qualified
personnel, and passed as serviceable, before being used again.
19. When not in use, store the jack, fully lowered, in a safe, dry, childproof area.

20. Always examine 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.
21. Do not push a vehicle off the jack or start the engine while supported only
by the jack.
22. Do not use if an oil leak is apparent. Consult the Clarke Service
Department.
23. If more than one jack is used in unison, they must all be of the same rating
and be raised at the same speed to reduce the possibility of the load
slipping.
SAFETY SYMBOLS
The following safety symbols may be found on the product.
Read the user manual before use.
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 in LOLER, for having the jack thoroughly
examined.
ENVIRONMENTAL PROTECTION
1. Take care to ensure that if hydraulic oil is spilt that it 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.

PRODUCT FEATURES
UNPACKING
During transit or storage, it is possible that an air pocket may have developed
within the hydraulic ram, and the ram action may therefore appear to be
‘spongy’. In this case the jack may require purging as described on page 7.
If the jack does not reach its full height, the oil level may require topping up as
described in the Maintenance section.

OPERATION
RAISING A VEHICLE
1. Make sure that the vehicle is stable and is on firm level ground with the
wheels chocked before positioning the jack directly below the lifting point.
DO NOT rely upon the vehicle handbrake alone to prevent vehicle
movement.
2. Make sure that the jack is on solid ground. If not, place a piece of solid
wood of sufficient size to provide sufficient support below the jack.
3. Consult the vehicle owners manual to ascertain the location of the lifting
points and position the jack below the designated lifting point.
4. Locate the slotted end of the jack handle on to the release valve and turn
fully clockwise to close the valve.
5. Pump the handle and raise the ram so that the jack and lifting point are in
full contact. Before proceeding further, make one last check to make sure
that:
• the jack is vertical and stable.
• there are no obstructions to the lift and that the handle can move
freely up and down.
• all personnel are in a safe position.
6. When satisfied, continue to pump the handle and lift the load to the height
required.
7. Do not let anyone reach or work below the vehicle until it is firmly
supported on suitable axle stands.
LOWERING THE VEHICLE
1. The lowering speed is controlled by the amount you turn the release valve.
With the axle stands removed, check to make sure that there are no
WARNING: MAKE SURE THAT THE SAFETY PRECAUTIONS ARE STRICTLY
FOLLOWED. NO RESPONSIBILITY CAN BE ACCEPTED FOR INCORRECT USE
OF THE JACK
WARNING: ALWAYS LOWER IN A SLOW AND CONTROLLED MANNER, AND
CHECK THAT THERE ARE NO OBSTACLES IN THE PATH OF THE LOAD’S
DESCENT. BE VERY CAREFUL WHEN LOWERING HEAVY LOADS.

personnel in the immediate vicinity before removing the handle from its
housing, and engaging it with the release valve.
2. Very slowly turn the handle counterclockwise to open the release valve,
and let the jack lower the load, under complete control. Do not jerk the
valve open.
MAINTENANCE
IMPORTANT: Only fully qualified personnel should attempt to repair the jack.
INSPECTION
1. Always examine the jack before use, to ensure that all parts are correctly
located and secure. Check for hydraulic leaks, signs of damage or worn
parts. Do not use the jack unless it is perfectly serviceable.
• A slight dampness on the ram is normal, but where leakage is found,
the ram seals must be renewed by your Clarke Spares Department.
2. The jack must be fully inspected annually:
• Check for cracks and deformation of components.
• Check operation and top up the oil level. (see below).
• Remove rust or corrosion and repaint to prevent corrosion.
• Make sure that all decals and warning notices are in place and
legible.
3. After use, store the jack with the ram in its lowest position. This not only
releases the pressure in the hydraulic ram, but also prevents any possibility
of corrosion to the ram.
4. Do not leave the jack in the open, exposed to the weather. Keep under
cover. If stored for long periods, examine before use, clean, and re-oil. For
servicing, speak to your CLARKE dealer or CLARKE Service department.
TOPPING UP THE OIL
It can be necessary from time to time to top up the hydraulic oil level as
follows.
1. Turn the release valve counterclockwise and let the ram retract to its lowest
position.
• It can be necessary to apply force to the saddle for lowering without
any weight on the jack.
2. With the jack in the level position, remove the filler plug and stand upright.
• The oil should be level with the bottom of the oil filler hole.

3. If below this, top up.
4. Do not overfill. Only use the correct type of oil such as Clarke hydraulic oil
(part number 3050830).
5. Replace the filler plug.
6. Check the jack for correct operation and purge any air from the system as
described below.
PURGING AIR FROM THE JACK
1. Turn the release valve counterclockwise one full turn to open.
2. Pump the handle eight full strokes.
3. Turn the release valve clockwise to close the valve.
4. Pump the handle until the ram reaches maximum height and continue to
pump several times to remove trapped air.
5. Turn the release valve counterclockwise one full turn and lower the ram to
its lowest position. Apply pressure if necessary.
6. Turn the release valve clockwise to the closed position and check for
correct operation. It may be necessary to perform the procedure more
than once to evacuate all the air.
