Starting could require many pulls de-
pending on how badly the unit is
flooded. If engine still fails to start, refer
to the
TROUBLESHOOTING TABLE or
contact your Sears Service Centre.
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 must be replaced
if any part is worn to less than 0.020 inch
(0.5 mm) thick. Repairs on a chain brake
should be made by your Sears Service
Centre. Take your unit to the place of pur-
chase or to the nearest Sears Service
Centre.
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 ac-
tivated 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 dis-
engaged 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.

Braking function control
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. Hold the
handles with both hands and apply full
throttle. Activate the chain brake by turn-
ing your left wrist against the hand guard
without releasing your grip around the
front handle. The chain should stop imme-
diately.
Inertia activating function control
WARNING: When performing the
following procedure, the engine must
be turned off.
Hold the chain saw approximately 14”
(35 cm) above a stump or other wood-
en surface. Release your grip on the
front handle and use the weight of the
saw to let the tip 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
S Check chain tension before first use
and after 1 minute of operation. See
CHAIN TENSION in the MAINTENANCE
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 parts as necessary.
S Keep the chain out of dirt and sand.
Even a small amount of dirt will
quickly dull a chain and increase the
possibility of kickback.
S Practice cutting a few small logs us-
ing the following steps. This will help
you get the “feel” of using your saw
before you begin a major sawing op-
eration.
S Squeeze the throttle trigger and al-
low 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
entire time you are cutting.
S Allow the chain to cut for you. Exert
only light downward pressure.
S Release the throttle trigger as soon
as the cut is completed, allowing
the engine to idle. If you run the
saw at full throttle without a cutting
load, unnecessary wear can occur.
S To avoid losing control when cut is
complete, do not put pressure on
saw at end of cut.
S Stop engine before setting saw down.
TREE FELLING TECHNIQUES
WARNING: Check for broken or
dead branches which can fall while
cutting causing serious injury. Do not
cut near buildings or electrical wires if
you do not know the direction of tree
fall, nor cut at night since you will not
be able to see well, nor during bad
weather such as rain, snow, or strong
winds, etc.
S Carefully plan your sawing operation
in advance.
S Clear the work area. You need a
clear area all around the tree so you
can have secure footing.
