IMPORTANT POINTS TO REMEMBER
When pulling the starter rope, do not use the full
extent of the rope as this can cause the rope to
break. Do not let starter rope snap back. Hold
the handle and let the rope rewind slowly.
For cold weather starting, start the unit at full
choke; allow the engine to warm up before
squeezing the throttle trigger.
NOTE : Do not cut material with the choke/
fast idle lever at the FULL CHOKE position.
STARTING A COLD ENGINE (or a
warm engine after running out of
fuel)
NOTE : In the following steps, when the
choke/fast idle lever is pulled out to the full
extent, the correct throttle setting for starting
is set automatically.

3. Pull out choke/fast idle to the full extent
(to the FULL CHOKE position).
4. Pull the starter rope sharply 5 times with
your right hand. Then, proceed to the
next step.
NOTE : If the engine sounds as if it is trying
to start before the 5th pull, stop pulling and
immediately proceed to the next step.

6. Pull the starter rope sharply with your
right hand until the engine starts.
7. Allow the engine to run for approximately
30 seconds. Then, squeeze and release
throttle trigger to allow engine to return to
idle speed.
STARTING A WARM ENGINE
1. Move ON/STOP switch to the ON position.
2. Slowly press the primer bulb 6 times.
3. Pull the choke/fast idle lever out to the
HALF CHOKE position.
4. Pull the starter rope sharply with your
right hand until the engine starts.
5. Squeeze and release throttle trigger to
allow engine to return to idle speed.
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.
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 0,02″ (0,5
mm) thick. Repairs on a chain brake should be
made by an authorized service dealer. Take
your unit to the place of purchase if purchased
from a servicing dealer, or to the nearest autho-
rized 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, ei-
ther manually or by centrifugal force.
S If the brake is already activated, it is disen-
gaged 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 fol-
lowing 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.
