OPERATING THE CHAIN BRAKE
See Figures 4 - 5.
Check the operating condition of the chain brake
prior to each use.
 Using the back of your left hand, engage the
chain brake by pushing the chain brake lever/
hand guard toward the bar while the chain is
rotating rapidly.
 Reset the chain brake back into the RUN posi-
tion by grasping the top of the chain brake lever/
hand guard and pulling toward the front handle
until you hear a click.
WARNING:
If the chain brake does not stop the chain imme-
diately, or if the chain brake will not stay in the
run position without assistance, take the saw to
a qualified service center for repair prior to use.
NOTICE:
Before each use, check to make sure that
the chain is properly tensioned. A cold chain
is correctly tensioned when there is no slack
on the underside of the guide bar, the chain
is snug, and it can be turned by hand without
binding. During normal saw operation, the tem-
perature of the chain increases. The drive links
of a correctly tensioned warm chain will hang
approximately .050 in. out of the bar groove.
See the Adjusting the Chain Tension instruc-
tions in the Maintenance section of this manual
to properly adjust the chain tension.
STARTING THE ENGINE
See Figures 6 - 9.
The starting method differs depending on whether
the engine is cold or warm.
WARNING:
Keep your body to the left of the chain line.
Never straddle the saw or chain, or lean over
past the chain line.
 Place the chain saw on level ground and ensure
that no objects or obstructions are in the imme-
