DIFFICULT STARTING (or starting a
flooded engine)
The engine may be flooded if it has not started
after 10 pulls.
Flooded engines can be cleared of excess fuel
by following the warm engine starting proce-
dure listed above. Ensure the ON/STOP
switch is in the ON position.
Starting could require many pulls depending on
how badly unit is flooded. If engine still fails to
start, refer to 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 authorized 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 authorized service deal-
er. Take your unit to the place of purchase if
purchased from a servicing 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.
IMPORTANT POINTS
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 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:
checked several times daily. The engine must
be running when performing this procedure.
This is the only instance when the saw should
be placed on the ground with the engine run-
ning.
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.

WARNING:
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.

CUTTING METHODS

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.
S Practice cutting a few small logs using the
following techniques to get the "feel" of us-
ing your saw before you begin a major
sawing operation.
S Squeeze the throttle trigger and allow the
engine to reach full speed before cutting.
S Begin cutting with the saw frame
against the log.
S Keep the engine at full speed the entire
time you are cutting.
S Allow the chain to cut for you. Exert only
light downward pressure. If you force
the cut, damage to the bar, chain, or en-
gine can result.
