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 autho- rized service dealer if any part is worn to less than 0,5 mm thick. Repairs on a chain brake should be made by an authorized service 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.
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 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 top of the guide bar fall forward and contact the stump. When the tip of the bar hits the stump, the brake should activate.
CUTTING METHODS
IMPORTANT POINTS
SCheck chain tension before first use and af- ter 1 minute of operation. See CHAIN TEN-
SION in the ASSEMBLY section.
SCut wood only. Do not cut metal, plastics, masonry,
SStop the saw if the chain strikes a foreign ob- ject. Inspect the saw and repair or replace parts as necessary.
SKeep the chain out of dirt and sand. Even a small amount of dirt will quickly dull a chain
and thus increase the possibility of kickback.
SPractice cutting a few small logs using the following techniques to get the “feel” of using 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 engine can result.
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 with- out a cutting load, unnecessary wear can
occur to the chain, bar, and engine.
STo avoid losing control when cut is com- plete, do not put pressure on saw at end
of cut.
SStop 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 build- ings 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 im- mediately.
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.
