 • When the brake operates, release the throttle lever

to slow down the engine speed. Continuous opera-
tion with the brake engaged will generate heat from
the clutch and may cause trouble.

At machine inspection prior to each job, check the
operating condition of the brake following the steps.

1. Start the engine and grasp the handle securely with

both hands.

2. Pulling the throttle lever to maintain the chain opera-

tion, push the brake lever (left-hand guard) down
toward the front using the back of your left hand.

3. When the brake operates and the chain is stopped,

release the throttle lever.

4. Release the brake.

■ 

STOPPING THE ENGINE

1. Release the throttle lever to allow the engine to idle

for a few minutes.

2. Set the switch to the “O” (STOP) position.

6. Sawing

1. H and L needles are restricted within the number of

turn as shown below.

H needle :   -1/4
L needle :    -1/4

2. Start the engine and allow it to warm up in low speed

for a few minutes.

3. Turn the idle adjusting screw (T) counterclockwise

so that the saw chain does not turn. If the idling
speed is too slow, turn the screw clockwise.

4. Make a test cut and adjust the H needle for best

cutting power, not for maximum speed.

CHAIN BRAKE

The chain brake is a device which stops the chain in-
stantaneously if the chain saw recoils due to kickback.
Normally, the  brake is activated automatically by inertial
force.  It can also be activated manually by pushing the
brake lever (left-hand guard) down toward the front.
When the brake operates, a yellow cone pops up from
the base of the brake lever.

Releasing the Brake

Pull the brake lever up toward the left-hand handle until
it clicks into place.

Before proceeding to your job,
read the section “For Safe
Operation”. It is recommended
to first practice sawing easy
logs. This also helps you get
accustomed to your unit.

Always follow the safety regu-
lations. The chain saw must
only be used for cutting wood.
It is forbidden to cut other
types of material. Vibrations
and kickback vary with differ-
ent materials and the require-
ments of the safety regulations
would not be respected. Do
not use the chain saw as a le-
ver for lifting, moving or split-
ting objects. Do not lock it over
fixed stands. It is forbidden to
hitch tools or applications to
the PTO other than those
specified by the manufacturer.

•   It is not necessary to force the saw into the cut. Ap-

ply only light pressure while running the engine at
full throttle.

•   When the saw chain is caught in the cut, do not

attempt to pull it out by force, but use a wedge or a
lever to open the way.
