SAFETY PRECAUTIONS

Parts List Cont

WARNING

Failure to comply with these rules and precautions, may result in loss of

load, damage to, or failure of the equipment, or even personal injury.

1. DO NOT exceed the load capacity for each jib position (as marked on the
jib). The capacities for each model are shown in tables on the inside front
cover.

IMPORTANT:

If the load capacity decal becomes worn or illegible, contact Clarke

International Spares Division, on 020 8558 6696 for replacement.

2. Ensure that the equipment is correctly assembled, and that all the bolts and
pins are in place and secure.

3. Only use chains, slings, hooks etc. with a rated capacity equal to, or greater
than that of the load. Check that they are secure and will not slip under load.

4. Only use the crane on a solid, flat, level surface which is capable of taking
the load. Avoid moving the crane over rough surfaces.

5. Lower the load as much as possible before moving the crane. Do not use the
crane to transport loads.

6. Do not stand under the load, or above the jib. Be aware that if the load slips
or falls, the jib may rise suddenly.

7. Use appropriate safety equipment, such as protective footwear, when using
this crane.

8. Ensure the crane operator is skilled and trained in both operation and safety
aspects.

9. Always inspect the crane before use to ensure it is in good condition, and
replace any damaged or worn parts.

10. When replacing parts, use only those supplied by Clarke International. Refer
to Parts List.

11. Ensure that the crane is properly maintained, and lubricated at all times, and
that no rust or other forms of corrosion is allowed to weaken any part of the
crane.

12. If the crane has been subjected to an abnormal load or shock, it should be
removed from service immediately and fully inspected by qualified personnel.

PREPARATION FOR USE

The crane is packed, fully assembled, in the fully folded position. On unpacking
check to ensure that no damage occurred during transit, and that all parts are
present according to the packing list.

1. Withdraw the locking pins (Item 21 Page 7), lower the legs, and lock in position
with the same pin, securing with the “R” clips (Item 20 Page 7).

2. Before operating the crane, replace the oil plug on the cylinder with the
holed one supplied.

3. Test the operation of the crane without a load (refer to ‘Operation’ for raising
and lowering the jib). If the ram operation appears ‘spongy’, it is possible
that air may have entered the system. Raising the lowering the jib a few
times will dispel any air and normalise the ram operation.

If the jib does not reach its full height, the rams hydraulic oil may need topping
up, (ref ‘Maintenance’).

OPERATION

IMPORTANT: Before attempting to lift, ensure the hook is directly above the point
of lift, and the point of lift is directly above the centre of gravity on the load.

Select the required jib arm length according to the load to be lifted and access
available. Always use the shortest jib length possible to give the greatest safety
margin and stability. Lock the jib extension into position with the link pin ( Item 13
page 7)

To raise the jib arm pump the hydraulic handle slowly to take the weight and
check the stability of the load before pumping to the desired height.

To lower the jib, slowly unscrew the valve knob (item B Page 7) the more the
valve is released, the faster the load will lower.

Take care when lowering heavy loads

MAINTENANCE

1. Always inspect the crane before use for visible signs of damage, leaking
hydraulic fluid, loose, worn or missing parts.

2. Periodically check the crane for any damage, such as bent, loose or
missing bolts and pins. Do not use a damaged crane. The bolts and pins
used in the crane are specially designed for use, at the cranes’ rated
capacity. If replacements are required, contact CLARKE International
Spares Department. Do not use substitute components.

3. Lubricate all the moving parts monthly with a general purpose oil or grease
as appropriate. Keep a light film of oil on the ram to prevent rust.

4. If the jib does not reach its full height, check the ram hydraulic oil level as
follows:

a. Raise the jib to the horizontal position and support the end.

b. Remove the ram to jib link pin (item 11 Page 7).

c. Lower the ram fully by unscrewing the large valve knob (B

Page 7). With the ram in the fully retracted position, the oil
should reach the level of the vent plug. Top up if necessary
with Clarke hydraulic oil (part number 3050830).

NOTE: We recommend that the hydraulic oil is changed after every 100 hours

of operation.

5. Replace the vent plug and re-attach the ram to the jib.

NOTE: When not in use, the crane should be stored with the jib in its lowest

position so there is no load on the ram, and the ram is not xposed to
the elements.

If the crane is to be stored, or transported horizontally, the transit plug
must be fitted to avoid leakage.
