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 re-

wind 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 attempt to cut material with

the choke/fast idle lever in the FULL CHOKE

position.

HELPFUL TIP

If your engine still does not

start after following these

instructions, please call

1--800--554--6723.

STARTING A COLD ENGINE (or warm

engine after running out of fuel)

NOTE:

extent, the correct throttle setting for starting

is set automatically.

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 call

1-800-554-6723.

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.
