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.
WARNING
Muffler surfaces are very hot during and after
operation of the chain saw, keep all body parts away
from the muffler. Serious burns may occur if contact is
made with the muffler.
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.
CHAIN BRAKE

STORING THE CHAIN SAW (1 MONTH OR
LONGER)
1. Drain all fuel from tank into a container approved for
gasoline.
2. 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.
3. Drain all bar and chain oil from tank into a container
approved for oil.
4. Clean all foreign material from the saw.
5. Store it in a well-ventilated place that is inaccessible to
children.
Note: Keep away from corrosive agents such as garden
chemicals and deicing salts.
Abide by all federal and local regulations for the safe
storage and handling of gasoline. Excess fuel can be used
in other 2-cycle engine powered equipment requiring 50:1
ratio.
