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
•If the 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,
•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.
