CARBURETTOR ANTI-FREEZE MECHANISM
Operating the chain saw in temperatures of 0-5
℃
at times of
high humidity may result in ice forming within the carburettor,
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 at the back of the air cleaner 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.(F15)

HOW TO SWITCH BETWEEN OPERATING MODES (F15)

2.Remove the air cleaner cover from the cylinder cover
3.Loosen a screw and remove the screen on the back of the
air cleaner cover.
4.Reattach the screen right side left so as to the anti-icing
plate is on the right. Reinstall the cover.
