INSPECTING AND CLEANING CHAIN BRAKE
See Figures 72 - 73.
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.
Always keep the chain brake mechanism clean and lightly
lubricate the linkage.
Always test the chain brake performance after servicing or
cleaning. Refer to
Operating Chain Brake for additional
information.
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)
Drain all fuel from tank into a container approved for
gasoline.
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.
Squeeze primer bulb several times to purge fuel from
carburetor.
Drain all bar and chain oil from tank into a container
approved for oil.
Clean all foreign material from the saw.
Store it in a well-ventilated place that is inaccessible to
children.
NOTE: Keep away from corrosive agents such as garden
chemicals and de-icing salts.
Abide by all federal and local regulations for the safe storage
and handling of gasoline. Excess fuel should be used in other
2-cycle engine powered equipment.
