MAINTENANCE

BEFORE USE.

Inspect for distortion of components, and security of all nuts and bolts. If in doubt, do not use.

Have damaged parts repaired or replaced. If necessary, consult your CLARKE dealer.

EVERY 6 MONTHS

1.

Oil all joints, linkages, the pump roller and front wheel hubs.

2.

Apply grease to the caster bearings.

NOTE: Lubrication and cleanliness is important as dirt, rust etc can cause a jerky action

which could damage internal components.

ANNUALLY

Carry out a thorough inspection for serviceability of components & check for oil leaks. Only a very

slight oil seepage is permissible. If a leak is evident, do not use jack...consult your CLARKE dealer.

STORAGE

Store in a dry place, with the ram fully retracted, where it cannot be attacked by the

elements. If stored for long periods, inspect at least once a year, clean and re-oil. For

servicing, contact your CLARKE dealer, or CLARKE International Service Dep’t.

FAULT FINDING

If the jack does not operate satisfactorily, there may be air in the system, or the release valve

may be stuck. Try the following remedies, before contacting Clarke Service Dept.

1. JACK WILL NOT RAISE LOAD

1.1 Low Oil Level

a.

Ensure the ram is fully retracted by turning the handle fully anticlockwise.

b.

With the jack in a level position, turn the Release Valve fully anticlockwise and remove it.

c.

The oil level should be level with the bottom of the threads inside the oil chamber. If

necessary, top up by removing the vent plug, directly on top of the ram, located at

the base of the handle housing and fill to the required level with CLARKE HYDRAULIC

OIL ONLY (See your CLARKE dealer. Quote Part No. 3050830 for 1 litre bottle). It may

be necessary to pull off the cover plate to gain access to the vent plug.

d.

Reinstall the vent plug and Release Valve, closing it fully, then pump handle until

the arm reaches its full height.

e.

Open Release Valve and step on saddle forcing it to lower as quickly as possible.

repeat this procedure three or four times.

f.

Finally, raise jack under load to test its operation.

1.2 Air in the System

a.

Open Release valve and pump handle fully, 6 or 7 times to purge air.

b.

Close release Valve and try again.

1.3 Release valve seat dirty

a. Pull lifting arm up and down a few times with the release valve open. If necessary, the

valve may be removed and the valve and seat cleaned.
