SAFETY PRECAUTIONS

1. Do not exceed the rated capacity of the jack.

2. Do not allow personnel to operate the jack unless they have read these

safety precautions.

3. Do not operate the jack if damaged.

4. Use the jack in a suitable, 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. Avoid

soft/unmade ground as the jack may sink in or move.

7. Ensure non-essential persons keep a safe distance whilst the jack is in use.

8. Ensure there are no personnel or obstructions under the vehicle before

lowering.

9. Do not work under the vehicle until it is fully supported by axle stands.

10. Keep hands etc clear of the vehicle until lifting is complete.

11. Ensure that you can see the saddle and jacking point throughout the

jacking operation in case there is any relative movement.

12. Always ensure 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 recommended lifting points by referring to

the vehicle owners manual. Ensure the lifting point is not corroded.

14. Never tamper with the jack or modify it in any way, as this could prove to

be dangerous and will invalidate the guarantee. Only use the jack for the

purpose for which it is intended.

15. Use appropriate safety equipment, such as protective footwear, when

using this jack.

16. Ensure that the jack is properly maintained and lubricated at all times, and

that no corrosion is allowed to weaken any part of it.

17. 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.

18. When not in use, store the jack, fully lowered, in a safe, dry, childproof area.

19. Always inspect the jack before use. Ensure that all parts are in good

condition and operating smoothly, and that no cracks or distortion is

apparent. If in doubt do not use.

Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com

20. Never push a vehicle off the jack or start the engine while supported only

by the jack.

21. Do not use if an oil leak is apparent. Consult the Clarke Service

Department.

22. If more than one jack is used in unison, they must all be of the same rating

and be raised at the same speed/height 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 owners

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

(CBJ5B shown)

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 of air as described on

page 8.

If the ram does not reach its full height, the oil level may require topping up, as

described in the Maintenance section.

OPERATION

RAISING A VEHICLE

1. Ensure the vehicle is stable and is on firm level ground with the wheels

chocked before positioning the jack so that is directly beneath the lifting

point. DO NOT rely upon the vehicle handbrake alone to prevent vehicle

movement.

2. Ensure the jack is on solid ground. If not, place a suitable piece of solid

wood of sufficient size to provide adequate support beneath the jack.

3. Consult the vehicle owners manual to ascertain the location of suitable

jacking points and position the jack beneath the designated lifting point.

4. Locate the oval end of the jack handle on to the release valve and turn

fully clockwise to close the valve.

5. Set the screw extension in contact with the lifting point. Pump the handle

and raise the ram so that the jack and lifting point are in full contact.

Before proceeding further, make one final check to ensure that:

• the jack is completely 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, well away from the underneath

of the vehicle.

6. When satisfied, continue to pump the handle and lift the load to the height

required.

7. NEVER allow anyone to get beneath the load until it is firmly supported on

suitable, properly rated 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 ensure that there are no personnel

WARNING: ENSURE 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 EXTREMELY CAREFUL WHEN LOWERING HEAVY LOADS.

Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com

in the immediate vicinity before removing the handle from its housing, and

engaging it with the release valve.

2. Very slowly turn the handle anticlockwise to open the release valve, and

allow the jack to lower the load, under complete control. NEVER, under

any circumstances, jerk the valve open.

MAINTENANCE

IMPORTANT: Only fully qualified personnel should attempt to repair the jack.

INSPECTION

1. Always visually inspect 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 Service Department.

2. The jack should be fully inspected annually as follows:

• Check for cracks and deformation of components.

• Check operation and top up the oil level. (see below).

• Remove completely, any rust or corrosion and repaint to prevent

further corrosion.

3. After use, store the jack with the ram in its lowest position. This not only

relieves 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, inspect before use, clean, and re-oil. For

servicing, contact your CLARKE dealer or CLARKE Service dept.

TOPPING UP THE OIL

It may be necessary from time to time to top up the hydraulic oil level.

Proceed as follows.

1. Turn the release valve anti-clockwise and allow the ram to retract to its

lowest position.

• It may be necessary to apply force to the saddle for lowering

without any weight on the jack.

2. With the jack upright, remove the filler plug.

• The oil should be level with the bottom of the oil filler hole.

3. If below this, top up.

Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com

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 several 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.
