CHAINBRAKE
_b'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 must
be replaced if any part is worn to tess
than 0.020" (0.5 ram) thick. Repairs on
a chain brake should be made by your
Sears Service Center. Take your unit
to the piace of purchase or to the near-
est Sears Service Center.
• 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).
• Ifthe brake is already activated, it is
disengaged by puiting the front hand
guard back toward the front handle
as far as possible.
• When cutting with the saw, the chain
brake must be disengaged.
Braking function control
CAUTION: The chain brake must be
checked several times daily. The en-
gine must be running when performing
this procedure. This is the onIy
instance when the saw shouid be
placed on the ground with the engine
running.
Place the saw on firm ground. Grip the
rear handle with your right hand and
the front handle with your left hand.
Apply futt 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
shoutd stop immediately.
Inertia activating function control
_kWARNING: When performing
the foitowing procedure, the engine
must be turned off.
Grip the rear handte with your right hand
and the front handle with your teft hand.
Hotd the chain saw approximately 14
inches (35 cm) above a stump or other
wooden surface. Reiease 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.
OPERATING TIPS
• Check chain tension before first use
and after 1 minute of operation, and
each time before you start the chain
saw. See CHAIN TENSION in the
MAINTENANCE section.
• Cut wood only. Do not cut metaI, plas-
tics, masonry, non-wood building ma-
terials, etc.
• Stop the saw if the chain strikes a
foreign object. Inspect the saw and
repair or replace 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 rite.
• Keep the chain out of dirt and sand.
Even a smaII amount of dirt will dull a
chain, increase the possibility of kick-
back, and require chain sharpening or
replacement.
• Practice cutting a few small logs us-
ing the following techniques to get
the "feeF of using your saw before
you begin a major sawing operation.
• Squeeze the throttIe trigger and allow
the engine to reach full speed before
cutting.
• Begin cutting with the saw frame
against the log.
• Keep the engine at full speed the
entire time you are cutting.
• Altow the chain to cut for you. Exert
onty light downward pressure, tf
you force the cut, damage to the
bar, chain, or engine can result.
• Release the throttle trigger as soon
as the cut is completed, allowing
the engine to idle. Ifyou run the saw
at full throttle without a cutting toad,
unnecessary wear can occur to the
chain, bar, and engine. To maxi-
mize operating efficiency, do not
run the engine for longer than 30
_econd_ at a time at full throttle.
• To avoid losing control when cut is
complete, do not put pressure on
saw at end of cut.
• Stop the engine before setting the
saw down after cutting.
