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.

n Allow the muffler to cool.

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

n Remove the deflector retaining screws.

n Lift the deflector to access the spark arrestor screen.

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

inspecting and cleaning CHAIN BRAKE See Figures 72 - 73.

n Remove the clutch cover and clean the chain brake com- ponents. Check wear on the brake band and replace if worn or deformed. The band thickness should not be less than 0.024 in., or worn halfway through.

n Always keep the chain brake mechanism clean and lightly lubricate the linkage.

n Always test the chain brake performance after servicing or cleaning. Refer to Operating Chain Brake for additional information.

n Check the chain catcher and replace if damaged.

WARNING:

Even with daily cleaning of the mechanism, the depend- ability of a chain brake to perform under field conditions cannot be certified. Keep the SAFE-T-TIP nose guard on the saw’s guide bar and use proper cutting techniques.

STORING THE CHAIN SAW (1 MONTH OR LONGER)
