ADJUSTING THE CARBURETTOR: The carburettor on your unit has been factory adjusted but may

1. Stop the engine and screw in both H and L needles until they stop. Never
force them. Then set them back the initial number of turns as shown below.
H Needle: 1 3/8
L Needle 1 ¼
2. Start the engine and allow it to warm up at half-throttle.
3. Turn the L Needle slowly clockwise to nd a position where idling speed is
maximum, then set the needle back a quarter (1/4) turn counter-clockwise.
4. Turn the idle adjusting screw (T) counter-clockwise so that the chainsaw does not turn. If idling speed
is too slow, turn the screw clockwise.

CHAIN BRAKE: This machine is equipped with an automatic brake to stop chainsaw rotation upon
occurrence of kickback while in saw cutting operation. The brake is automatically operated by inertial
force which acts on the weight tted inside the front guard. This brake can also be operated manually with
the front guard turned down to the guide bar. (F15). To release the brake, pull up the front guard toward
the front handle until you hear it click.
How to conrm brake operation:
1. Turn off the engine
2. Holding the chainsaw horizontally, release your hand from the front handle, hit the tip of the guide bar to
a stump or a piece of wood and conrm brake operation. Operating level varies by bar size. (F16) In case
the brake is not effective, ask our dealer inspection and repairing the engine.
3. If being kept rotating at high speed with the brake engaged, can heat the clutch and cause a lot of
problems. When the brake is depressed while in operation, immediately release your ngers from the
throttle lever and keep the engine idling.
