MAINTENANCE

GENERAL

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 exposed to the elements. Keep under cover.

3. Do not attempt to adjust or tamper with the ram assembly, there are no

serviceable parts. Contact your Clarke service department for servicing.

4. Always visually inspect the crane before use to ensure that all parts are

correctly located and secure. Check for hydraulic leaks, signs of damage

or worn parts and check the wheels and castors for serviceability.

5. A slight dampness on the ram is normal but where leakage is apparent the

ram seals must be renewed. Consult your Clarke service department.

EVERY THREE MONTHS

1. Pins and bolts should be removed and inspected for wear, deformation or

cracks. If any are apparent, the pin or bolt should be renewed.

2. Check the hydraulic ram operation and check the hydraulic oil level.

ANNUALLY

The crane should be fully inspected annually by a competent person.

1. Check wheels and castors to ensure they move freely without undue wear

to their bores and that the wheels are not cracked or damaged.

2. Remove any rust or corrosion and repaint to prevent further corrosion.

3. Ensure that all decals and warning labels are in place and legible.

HYDRAULIC OIL

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

1. Lower the jib to its lowest position and remove the bolt that joins the ram

(21) to the jib (7).

2. Rest the ram against the main support post and raise and prop up the jib

(7). Use a cable or similar ensure the ram does not drop.

3. Remove the vent plug from the side of the ram.

4. Top up the oil until it is level with the hole before replacing the vent plug.

• We recommend that the hydraulic oil is changed after every 100

hours of operation using Clarke hydraulic oil (part number 3050830).

• Do not mix different types of oil.
