INSPECTING AND CLEANING CHAIN
BRAKE
See Figures 66 - 67.
 Remove the clutch cover and clean the chain
brake components. 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
dependability 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-lubricant 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 lubricant from tank into
a container approved for lubricant.
 Clean all foreign material from the saw.
 Store it in a well-ventilated place that is inac-
cessible 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.

HIGH ALTITUDE ENGINE OPERATION

Your engine is configured for operation below 2000
feet altitude at the factory. Your engine must be
reconfigured for operation above 2000 feet alti-
tude. Operating the engine with the wrong engine
configuration at a given altitude may increase its
emissions, decrease fuel efficiency, degrade per-
formance, and cause irreversible damage. Engines
configured for high altitude operation cannot be
operated in standard altitude conditions. A qualified
service center should ensure that your engine is
properly configured for your location.
