Carburetor anti-freeze mechanism
Operating the 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 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 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 anti-freeze mode
before use.(F18)
(1) Normal operating mode
(2) Anti-freeze mode
(3) Cylinder cover
(4) ‘Sun shine’ mark
(5) ‘Snow’ mark
Continuing to use the product in anti-freeze
mode even when temperatures have risen and
returned to normal 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 normal operating mode if there is no
danger of icing occurring.
