INSPECTING/CLEANING THE SPARK arrestor screen

See Figure 72.

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 the saw in good condition.

WARNING

Muffler surfaces are very hot during and after operation of the chain saw. To avoid serious personal injury, keep all body parts away from the muffler.

nAllow the muffler to cool.

nRemove the cylinder cover to gain access to the deflector where the spark arrestor screen is located.

nRemove the deflector retaining nuts.

nLift the deflector to access the spark arrestor screen.

nIf dirty, clean the spark arrestor screen with a small wire brush. Replace the screen if it is cracked or otherwise deteriorated.
