MAINTENANCE

CLEANING THE SPARK ARRESTING MUFFLER

See Figure 78.

The muffler is equipped with a spark arrestor screen. A faulty spark arrestor screen can create a fire hazard. Through normal use the screen can become dirty and should be inspected weekly and cleaned as required. Always keep the muffler and spark arrestor on your saw in good condition.

1.Allow the muffler to cool.

2.The spark arrestor screen is retained by the deflector. Remove the nuts and screen retainer to access the spark arrestor screen.

3.Replace the spark arrestor screen if it is cracked or otherwise deteriorated.
