CHAIN BRAKE

Ensure chain brake is disengaged by pulling

the front hand guard back toward the front han-

dle as far as possible. The chain brake must

be disengaged before cutting with the saw .

WARNING: The chain must not

move when the engine runs at idle speed. If

the chain moves at idle speed refer to CAR-

BURET OR ADJUSTMENT within this

manual. Avoid contact with the muffler. A hot

muffler can cause serious burns.

To stop the engine, move the ON/STOP

switch to the STOP position.

To start the engine, hold the saw firmly on

the ground as illustrated below. Make sure

the chain is free to turn without contacting

any object.

Hold saw firmly while pulling starter rope.

Use only 15″ --- 1 8 ″ ( 4 0 --- 4 5 c m ) o

rope

per pull.

IMPORTANT POINTS TO REMEMBER

When pulling the starter rope, do not use the full

extent of the rope as this can cause the rope to

break. Do not let starter rope snap back. Hold

the handle and let the rope rewind slowly .

For cold weather starting, start the unit at full

choke; allow the engine to warm up before

squeezing the throttle trigger.

NOTE: Do not cut material with the choke/fast

idle lever a t the FULL CHOKE position.

DIFFICULT STARTING (or starting a

flooded engine)

The engine may be flooded with too much

fuel if it has not started after 10 pulls.

Flooded engines can be cleared of excess

fuel by pushing the choke/fast idle lever in

completely (to the OFF CHOKE position)

and then following the warm engine starting

procedure listed above. Ensure the ON/

STOP switch is in the ON position. Starting

could require pulling the starter rope handle

many times depending on how badly the unit

is flooded. If engine fails to start, refer to the

TROUBLESHOOTING TABLE.

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 0,02″ (0,5

mm) thick. Repairs on a chain brake should be

made by an authorized service dealer. Take

your unit to the place of purchase if purchased

from a servicing dealer , or to the nearest autho-

rized master service dealer .

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 acti-

vated if the front hand guard is pushed for-

ward, either manually or by centrifugal

force.

S If the brake is already activated, it is disen-

gaged by pulling the front hand guard back

toward the front handle as far as possible.

S When cutting with the saw,the chainbrake

must be disengaged.
