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.

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.
