Important Points To Remember; Starting A Cold/Warm Engine; Difficult Starting; Chain Brake - Husqvarna 137 Instruction Manual

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 cotd 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
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.
1. Move ON/STOP switch to the ON posi-
tion.
2. Pull the choke/fast idle lever out to the full
extent (to the FULL CHOKE position).
3. Pull starter rope sharply with your right
hand a maximum of 10 times. Then, pro-
ceed to the next step.
NOTE: Ifthe engine sounds as if it is trying
to start before the 10th pull, stop pulling and
immediately proceed to the next step.
4. Push the choke/fast idle lever in to the
HALF CHOKE position.
5. Pull the starter rope sharply with your
right hand until the engine starts.
6. Allow the engine to run for approximately
30 seconds. Then, 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 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. 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 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 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.
• This saw is equipped with a chain brake.
The brake is designed to stop the chain if
kickback occurs.
• The inertia-activated chain brake is
activated if the front hand guard is pushed
forward, either manually (by hand) or
automatically (by sudden movement).
• If the brake is already activated, it is
disengaged by pulling the front hand guard
back toward the front handle as far as
possible.
• When cutting with the saw, the chain brake
must be disengaged.

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
