CLEAN AIR FILTER

CAUTION:

hours of operation, whichever comes first.

Clean more frequently in dusty conditions. A

used air filter can never be completely

cleaned. It is advisable to replace your air fil-

ter with a new one after every 50 hours of op-

eration, or annually, whichever comes first.

1. Loosen 3 screws on cylinder cover.

2. Remove cylinder cover.

3. Remove air filter cover and air filter.

4. Clean the air filter using hot soapy water.

Rinse with clean cool water. Air dry com-

pletely before reinstalling.
