in the ON position.
Starting could require pulling the start-
er rope handle many times depending
on how badly the unit is flooded.

CAUTION:
The chain brake must be
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 running.
Place the saw on firm ground. Grip the
rear handle with your right hand and
the front handle 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

should stop immediately.
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 metal, 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 file.
a chain brake should be made by your
Sears Service Center. Take your unit
to the place of purchase
or to the near-
est Sears Service Center.

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.
