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 authorized 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 authorized ser- vice dealer. Take your unit to the place of pur- chase if purchased from a servicing dealer, or to the nearest authorized master service dealer.
SThis saw is equipped with a chain brake. The brake is designed to stop the chain if kickback occurs.
S The
S If the brake is already activated, it is disengaged by pulling the front hand guard back toward the front handle as far as possible.
SWhen 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 proce- dure. This is the only instance when the saw should be placed on the ground with the en- gine running.
Place the saw on firm ground. Grip the rear handle with your right hand and the front han- 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 should stop immediately.
Inertia activating function control
WARNING: When performing the following procedure, the engine must be turned off.
Grip the rear handle with your right hand and the front handle with your left hand. Hold the chain saw approximately 14″ (35 cm) above a stump or other wooden 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
SCheck chain tension before first use, after 1 minute of operation, and each time be-
fore you start the chain saw. See CHAIN TENSION in the ASSEMBLY section.
SCut wood only. Do not cut metal, plastics,
masonry,
SStop the saw if the chain strikes a foreign object. Inspect the saw and repair or re- place 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.
SKeep the chain out of dirt and sand. Even a small amount of dirt will dull a chain, increase
the possibility of kickback, and require chain sharpening or replacement.
SPractice cutting a few small logs using the following techniques to get the “feel” of us- ing your saw before you begin a major sawing operation.
S Squeeze the throttle trigger and allow 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. If you force the cut, damage to the bar, chain, or en- gine can result.
S Release the throttle trigger as soon as the cut is completed, allowing the en- gine to idle. If you run the saw at full throttle without a cutting load, unneces- sary wear can occur to the chain, bar, and engine. It is recommended that the engine not be operated for lon-
ger than 30 seconds at full throttle.
STo avoid losing control when cut is com- plete, do not put pressure on saw at end of cut.
S Stop the engine before setting the saw down after cutting.
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 ale to see well, nor during bad weather such as rain, snow, or strong winds, etc. If the tree makes contact with any utility line, the utility company should be notified immediately.
SCarefully plan your sawing operation in ad- vance.
SClear the work area. You need a clear area
all around the tree so you can have secure footing.
SThe chain saw operator should keep on the uphill side of the terrain as the tree is
likely to roll or slide downhill after it is felled.
SStudy the natural conditions that can cause the tree to fall in a particular direction.
