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.

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.

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.
