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 (Front handle guard) down toward the front.
When the brake operates, a white cone pops up from the
base of the brake lever.
To release brake, pull up the front handle guard toward
the front handle till "click" sound is heard.
WARNING
When the brake operates, release the throttle lever to
slow down the engine speed. Continuous operation with
the brake engaged will generate heat from the clutch and
may cause trouble. Be sure to confirm brake operation
on the daily inspection.
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.
In case the brake is not effective, ask our dealer
inspection and repairing.
CARBURETOR ANTI-FREEZE MECHANISM
Operating chain saws in temperatures of 0 – 5°C at
times of high humidity may result in ice forming within the
carburetor, and this in turn may cause the output power
of the engine to be reduced or for the engine to fail to
operate smoothly.

This product has accordingly been designed with a venti-
lation hatch on the right side of the surface of the cylinder
cover to allow warm air to be supplied to the engine and
to thereby prevent icing from occurring.
Under normal circumstances the product should be
used in the normal operating mode, i.e., in the mode
which it is set at the time of shipment. However when
the possibility exists that icing may occur, the unit should
be set to operate in the anti-freeze mode before use.
Continuing to use the product in the anti-freeze mode
even when temperatures have risen and returned to nor-
mal, may result in the engine failing to start properly or
in the engine failing to operate at its normal speed, and
for this reason you should always be sure to return the
unit to the normal operating mode if there is no danger
of icing occurring.
HOW TO SWITCH BETWEEN OPERATING MODES
1. Flip the engine switch to turn off the engine.
2. Remove the cover to the air filter, remove the air
