In case the brake is not effective, ask our dealer for
inspection and repairs.
If the engine keeps rotating at high speed with the brake
engaged, the clutch will overheat causing trouble.
When the brake engages during operation, immedi-
ately release the throttle lever to stop the engine.

ICING PREVENTION SYSTEM
This system prevents icing of the carburetor which
sometimes happen while sawing in winter.
When your saw has stopped or slowed down abruptly,
use the system as follows:
1. Remove the air cleaner cover, air filter, and silencer.
(1) Cylinder cover
(2) Air cleaner cover
(3) Intake silencer
(4) Air filter
2. Unhook the hatch on the rear wall of the cylinder
cover and turn it upside down.
(1) Hatch
3. Install the covers as they are.
WARNING
• Never use the system in normal temperature
because that can cause starting failure due to
overheating of the carburetor.
■
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.
(1) Switch
1. Stop engine and screw in both H and L needles
until they stop. Never force. Then set them back the
standard number of turns as shown below.
H needle:
1 ± 1/4
L needle:
11/2 ± 1/4
2. Start engine and allow it a few minutes warming up
in low speed.
3. Turn L needle slowly clockwise to find the position
where idling speed is maximum, set the needle back
a quarter (1/4) turn counter clockwise. L needle
should be set in 1/4 turn either wise from the standard
position.
4. Turn idle adjusting screw (T) counterclockwise so
that saw chain does not turn. If idling speed is too
slow, turn the screw clockwise.
5. The carburetor has been equipped with a governor.
Make a test cut and adjust the H needle for best
cutting power, not for maximum speed.
WARNING
• Over revolution of H needle causes a lack of
power or a poor acceleration.
In such a case please turn the H needle a little
counterclockwise.
■
CHAIN BRAKE
This machine is equipped with an automatic brake to
stop saw chain rotation upon occurrence of kickback
during saw cutting. The brake is automatically operated
by inertial force, which acts on the weight fitted inside
the front guard.
This brake can also be operated manually with the front
guard turned down to the guide bar.
To release the brake, pull up the front guard toward the
front handle till a “click” sound is heard.
(1) Front handle
(2) Released
(3) Braking
(4) Brake lever
[Caution]
Be sure to confirm brake operation during daily inspec-
tion.
How to confirm:
1) Turn off the engine.
2) Holding the chain saw horizontally, release your
hand from the front handle, hit the tip of the guide
bar to a stump or a piece of wood, and confirm brake
operation. Operating level varies by bar size.
