SERVICE AND REPAIR

If the tool runs erratically or becomes inefficient although the air supply is in 
good order, it may be necessary to dismantle the tool. Such servicing and 
repair work should be carried out by qualified service technicians.

PERFORMANCE

Please note that factors other than the tool may effect its operation and 
efficiency such as reduced compressor output, excessive drain on the airline 
moisture or restrictions in the air-line, or the use of connectors of improper size 
or poor condition which will reduce air supply.

Grit or gum deposits inside the tool may also reduce its efficiency. This 
condition can be corrected by cleaning out the air strainer and flushing out 
the tool with gum solvent or oil, or failing this, the motor may require 
dismantling.

**Clarke Air Line Oil (part no. 3050825) is available from your CLARKE dealer .

STORAGE

If the tool is to be stored, or is idle for longer than 24 hours, run a few drops of 
Clarke air line oil into the air inlet, and run the tool for 5 seconds in order to 
lubricate the internal parts.

When not in use, disconnect from air supply, clean tool and store in a safe, dry 
place.

ACCESSORIES

A wide range of accessories is available including filter/regulators, lubricators, 
high-pressure hoses (5 to 50 metres) etc.

Contact your CLARKE dealer for further information or CLARKE International 
Service Department on 01992 565333.
