PURGING THE HYDRAULIC SYSTEM

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’. As the ram

is self bleeding, any air will be dispelled and the ram action normalised by fully raising

and lowering the jib a few times.

Should the jib not reach its full height, the oil level should be checked as described in

the Maintenance section.

STORAGE & MAINTENANCE

STORAGE

1. ALWAYS store the crane with the jib in its lowest position. This prevents any

possibility of corrosion to the ram.

2. DO NOT leave the crane in the open or exposed to the elements. Keep under

cover.

3. Remove the pin and slide the jib extension back to its shortest position. Replace

the pin and R-clip to secure the jib extension.

4. Release the control valve to lower the jib assembly to its lowest position.

5. Store the pump handle in its bracket on the side of the main support post.

6. Fold the unit in an upright position by

removing the front pins from the base and

raising the front legs to a vertical position.

Insert the locking pins into the L-brackets to

secure.

7. Replace the front pins into the holes in the

base.

MAINTENANCE

1. The crane should be inspected periodically by

a competent person with load bearing bolts

should being removed and inspected for

wear, deformation or cracks. If any are

apparent the bolt should be renewed.

2. Check the hydraulic ram operation and

inspect for oil leaks. A slight dampness on the

ram is normal, but where leakage is

apparent, the ram seals must eventually be

renewed and the lost oil be replaced. Consult

your CLARKE service department.
