Operating
the
chain
saw
in
temperatures of 0-5°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 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
circumstance
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.
HOW TO SWITCH BETWEEN
OPERATING MODES(F16)

the engine.
