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 or c all

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 0.020″ (0.5 mm) thick. Repairs on a

chain brake should be made by an autho-

rized service dealer . Take your unit to the

place of purchase if purchased from a ser-

vicing dealer, or to the nearest authorized

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

activated 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

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.

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

S Check 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.

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 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.

S Keep 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.
