DIFFICULT STARTING (or starting a

fuel if it has not started after 10 pulls.
Flooded engines can be cleared of excess
fuel by following the warm engine starting
procedure listed above. Insure 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

CHAIN BRAKE
WARNING: If the brake band of the
chain brake 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 re-
placed by an authorized service dealer if any
part is worn to less than 1/32” thick. Repairs
on a chain brake should be made by an au-
thorized 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 top 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
IMPORTANT POINTS
S Check chain tension before first use and
after 1 minute of operation. 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.
S Keep the chain out of dirt and sand. Even a
small amount of dirt will quickly dull a chain
and thus increase the possibility of kickback.
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 en-
tire 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 engine can result.
