OPERATING YOUR UNIT

WARNING: The chain must not move

when the engine runs at idle speed. If the chain

moves at idle speed refer to CARBURETOR

ADJUSTMENTS within this manual. Avoid

contact with the muffler . A hot muf fler 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”--18” 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 at the FULL CHOKE position.

STARTING A COLD ENGINE (or a

warm engine after running out of

hand a maximum of 10 times. Then, pro-

ceed to the next step.

NOTE: If the engine sounds as if it is trying

to start before the 10th pull, stop pulling and

immediately proceed to the next step.

4. Push the choke/fast idle lever in to the

HALF 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 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 0.020″

(0.5 mm) thick. Repairs on a chain brake

should be made by an authorized service deal-

er . Take your unit to the place of purchase if

purchased from a servicing dealer, or to the

nearest authorized Husqvarna 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.
