■ ICING PREVENTION SYSTEM
This system prevents icing of the carburetor which some-
times 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.
2. Unhook the hatch on the rear wall of the cylinder
cover and turn it upside down.
3. Install the covers as they are.
WARNING
• Never use the system in normal temperature be-
cause that can cause starting failure due to over-
heating 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. 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.
NOTE
• 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 r elease the brake, pull up the front guard toward the
front handle till a “click” sound is heard.
[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 op-
eration. Operating level varies by bar size.
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, immediately
release the throttle lever to stop the engine.
