■ 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
ventilation hatch on the right side of the surface of
the insulator 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 to 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.
Stop the engine, remove the cylinder cover and

install the grommet A to the appropriate position of
the mode.
See ■ Maintenance part for how to remove the
cylinder cover.
