TROUBLESHOOTING

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.

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

Your Clarke air tool has been designed to give long and trouble free service. If, 
however, having followed the instructions in this booklet carefully, you 
encounter problems, take the unit to your local Clarke dealer.
