DIFFICULT STARTING (or starting a
flooded engine)
The engine may be flooded with too much
fuel if it has not started after 10 pulls.
Flooded engines can be cleared of excess
fuel by pushing the choke/fast idle lever in
completely (to the OFF CHOKE position)
and then following the warm engine starting
procedure listed above. Ensure the ON/
STOP switch is in the ON position.
Starting could require pulling the starter rope
handle many times depending on how badly
the unit is flooded. If engine fails to start, refer
to the TROUBLESHOOTING TABLE or call
1-800-554-6723.
CHAIN BRAKE
WARNING: If the brake band is
worn too thin it may break when the chain
brake is triggered. With a broken brake band,
the chain brake will not stop the chain. The
chain brake should be replaced by an autho-
rized service dealer if any part is worn to less
than 0.020″ (0.5 mm) thick. Repairs on a
chain brake should be made by an autho-
rized service dealer. Take your unit to the
place of purchase if purchased from a ser-
vicing dealer, or to the nearest authorized
master service dealer.
S
This saw is equipped with a chain brake.
The brake is designed to stop the chain if
kickback occurs.
S The inertia--activated chain brake is
activated if the front hand guard is pushed
forward, either manually (by hand) or
automatically (by sudden movement).
S If the brake is already activated, it is
disengaged by pulling the front hand guard
back toward the front handle as far as
possible.
S When cutting with the saw, the chain brake
must be disengaged.

CAUTION: The chain brake must be
checked several times daily. The engine
must be running when performing this proce-
dure. This is the only instance when the saw
should be placed on the ground with the en-
gine running.
Place the saw on firm ground. Grip the rear
handle with your right hand and the front han-
dle with your left hand. Apply full throttle by
fully depressing the throttle trigger. Activate
the chain brake by turning your left wrist
against the hand guard without releasing
your grip around the front handle. The chain
should stop immediately.
Inertia activating function control
WARNING:
When performing the
following procedure, the engine must be
turned off.
Grip the rear handle with your right hand and
the front handle with your left hand. Hold the
chain saw approximately 14″ (35 cm) above a
stump or other wooden surface. Release your
grip on the front handle and use the weight of
the saw to let the tip of the guide bar fall forward
and contact the stump. When the tip of the bar
hits the stump, the brake should activate.
OPERATING TIPS
S Check chain tension before first use, after
1 minute of operation, and each time be-
fore you start the chain saw. See CHAIN
TENSION in the ASSEMBLY section.
S Cut wood only. Do not cut metal, plastics,
masonry, non-wood building materials, etc.
S Stop the saw if the chain strikes a foreign
object. Inspect the saw and repair or re-
place parts as necessary. If the chain
jumps off the guide bar, inspect the chain
for damaged drive links before reinstalling.
Burrs on drive links, which prevent them
from entering the groove of the guide bar,
can be removed with a flat file.
S Keep the chain out of dirt and sand. Even a
small amount of dirt will dull a chain, increase
the possibility of kickback, and require chain
sharpening or replacement.
