SAFETY PRECAUTIONS

1. ALWAYS inspect the jack before use. Inspect for distortion of the column

and locking pins and the security of all parts. Check all parts are in good

condition and operating smoothly and that no cracks or distortion is

apparent. If in doubt DO NOT use.

2. If any part of jack fails to work properly, stop use and have it repaired or

replaced. NEVER attempt to repair jack while it is under load.

3. DO NOT use the jack for any purpose other than for which it is designed.

4. Ensure the jack is on a firm solid base and that there is no likelihood of it

slipping or sinking when under load.

5. Ensure the load is taken by the FULL lifting nose and that the point of lift on

the load is of sufficient strength to support the full load adequately.

6. ALWAYS ensure that the load is stabilised or supported in such a way that it

will not shift during lowering or lifting. Always lock and/or stabilise the load

to be lifted. The jack will not act as a load stabiliser.

7. ALWAYS use supports to stabilise the load once lifted. DO NOT rely upon the

jack to hold the load in position.

8. NEVER push a load off the jack.

9. All persons shall be clear of load being raised, lowered or pulled. NEVER

work under a raised load without using additional supports such as axle

stands. As an extra precaution insert a M12 steel bolt (not included)

through the hole in the beam immediately below the lifting mechanism to

act as a safety pin. Ensure there are no persons or obstructions beneath a

load before lowering.

10. Ensure there is a working gap between a vehicle being lifted and any

adjacent wall or object.

11. Ensure the vehicle handbrake is securely on and/or an automatic vehicle

transmission is in the park position before lifting.

12. Take care not to trap fingers within the moving parts.

13. ALWAYS keep a firm grip on the handle and support beam.

14. When using the jack to pull or drag a load, be aware that the load may

suddenly ‘give’, eg. pulling a tree stump etc. Take appropriate

precautions.

15. NEVER exceed the rated load of the jack as given in the specifications.

WARNING/If you exceed rated capacity, the shear pin will break and the

handle will drop.

16. DO NOT use additional bars/tubes in conjunction with the handle to

provide extra leverage. Use hand power only.

17. NEVER carry the jack by the handle as the column may drop and cause

harm to persons or property.

18. ALWAYS ensure that the lifting head climbing pin is located and locked in a

hole in the steel beam before releasing the pumping handle otherwise the

lifting head will automatically lower, causing the handle to move up and

down rapidly presenting a risk of serious injury.

19. The jack must have a minimum load of 50kg (110Ibs) to activate the

lowering step by step otherwise lifting head will drop.

OPERATING INSTRUCTIONS

OVERVIEW

RAISING A LOAD

WARNING: BEFORE LIFTING ENSURE SAFETY PRECAUTIONS ARE READ AND

UNDERSTOOD.

1. Before lifting assess the correct

jacking point for the load. If the

load is a vehicle, consult the

vehicle manufacturer's handbook

for the correct lifting point.

2. Pull the direction latch upwards

(fig.1) until it clicks into place.

Ensure it is locked in position with

the indent of the latch firmly

engaged with the notch on the

reversing switch.

Ensure that the foot of the jack is placed on a stable, strong base capable of

supporting the jack and the load.

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

• The foot of the jack should be immediately below the chosen lifting

point so that the lifting action is vertical. DO NOT attempt a lift with

the jack at an angle.

3. Raise the lifting toe to the jacking point on the load. The lifting head can be

raised manually into position.

• You will hear the mechanism clicking as you do this.

4. Place the lifting toe under the object to be lifted. You can pull the lifting

head up to the point of lift (or strain) without pumping the handle.

5. Hold the column (2) steady. Unclip the handle (4) by pulling it downwards

and pump it up and down with a full stroke to bring the lifting toe into

contact with the jacking point. Check that the toe is fully under the load

and lifting at the right point.

6. When you are sure that the jack and load are stable commence lifting by

pulling the handle down a full stroke. As the handle is pulled down you will

hear the climbing pin click into place as it locates in the next hole in the

column. At this point, relax the handle allowing the pin to take the load.

Raise the handle to the top of its stroke to take a fresh purchase and pump

the handle down again. Pressure will be felt on the downward stroke.

ALWAYS keep a firm grip on the handle.

• No extension of any sort should be applied to the handle to gain

extra leverage.

7. When the desired lifting height has been achieved, raise the handle

towards the column and clip it in the vertical position.

8. Place a M12 steel bolt (not supplied) through the hole immediately below

the lifting mechanism to act as a safety pin.

9. Put the handle in upright position before tripping the reversing latch to

lower the load.

WARNING: THE JACK IS FOR LIFTING OR PULLING AND MUST NOT BE USED TO

CONTINUOUSLY SUPPORT A LOAD. PLACE AXLE STANDS OR OTHER APPROPRIATE

SUPPORTS BENEATH A VEHICLE/LOAD.

LOWERING A LOAD

WARNING: THE JACK MUST BE LOADED WITH A MINIMUM OF 50KG (110LBS) TO

LOWER STEP BY STEP OTHERWISE THE LIFTING TOE WILL DROP RAPIDLY TO THE

BOTTOM OF THE COLUMN WHEN THE DIRECTION LATCH IS MOVED TO THE

LOWERING POSITION.

1. Jack the load up slightly, remove the safety pin if fitted and any previously

placed supports. Place the handle in the fully upright position.

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

2. Trip the reversing latch so that it is

in the down position with the

indentation on the latch

disengaged from the notch on the

reversing switch (see fig.2).

Keeping a firm grip on the handle,

commence lowering by pumping

the handle steadily up and down.

When lowering, you will feel

resistance on the upward (or

backward) stroke of the handle.

CAUTION: DO NOT RELEASE THE HANDLE UNTIL THE CLIMBING PIN HAS LOCKED

INTO PLACE. IF THE CLIMBING PIN IS NOT LOCKED INTO PLACE AND THE HANDLE IS

RELEASED, THE LIFTING HEAD WILL AUTOMATICALLY LOWER CAUSING THE HANDLE

TO MOVE UP AND DOWN RAPIDLY, PRESENTING A RISK OF SERIOUS INJURY.

PULLING, TENSIONING AND POSITIONING

WARNING: DO NOT PLACE AN EXCESSIVE STRAIN ON THE LOAD, EQUIPMENT OR

SUPPORTS WHEN USING THE JACK FOR PULLING OR TENSIONING.

The jack may be used for a variety of

other purposes such as tensioning

fences (See fig.3), pulling out tree

stumps (See fig.4) and positioning of

heavy items such as machinery. In all

cases, such operations should begin

with a risk assessment exercise

including consideration of the

following points.

When the jack is used for pulling or tensioning there

will be a tendency for the pulling force to move the

column away from the line of pull unless the far

end is restrained or fixed using suitable chains,

bolts, ropes etc. Any fixing/restraining items used

must be sufficiently robust for the pulling force that

will be applied to them.

Where other structures are used to stabilise the

column the operator must be certain that these

structures are sufficiently strong to resist the force

applied to them otherwise damage may occur to

the structure resulting in a sudden and dangerous

loss of tension.

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

When repositioning heavy items such as machinery, consideration should be

given to how the load will move once it is set in motion and sufficient

precautions taken to restrain the item from moving too far or in an

unpredictable way. Similar caution needs to be exercised when choosing

attachment/pushing/pulling points on machinery. These points must be

sufficiently strong to resist the forces applied to them.

It is the responsibility of the owner of the equipment to assess the safety

requirements for every new usage of the equipment and to take sufficient

safety precautions.

MAINTENANCE

Keep the moving parts clean and free from debris especially if used in a dirty

environment eg for tree stump removals.

Keep all parts of the jack gently lubricated to prevent any possibility of

corrosion If stored for long periods.

Store in a dry, childproof location where it cannot be damaged by the

elements..
