INSPECTING/CLEANING THE SPARK
ARRESTOR SCREEN
See Figure 71.
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 THE 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)
n Drain all fuel from tank into a container approved for
gasoline.
n Run the engine until it stops. This will remove all fuel-oil
mix that could become stale and leave varnish and gum
in the fuel system.
