Anti Freezing Window
Operating chain saws in temperatures of -25°C – 0°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 an anti-freezing window on the cylinder
shield to allow warm air to be supplied to the carburettor chamber and to thereby prevent icing
from occurring.
• Under normal circumstances the anti-freezing window should be set in the
close mode. In this case, the “SUN” marking is face outside.
• However when the possibility exists that icing may occur, the anti-freezing
window should be set in the open mode before use. In this case, the
“SNOW” marking is face outside.
Continuing to use the product in the anti-freezing 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 set the anti-freezing window to the close mode if there is no danger of icing
occurring.
1. Remove Cylinder cover
2. Pull the anti-freezing window (2) out, then turn it over and push it into the cylinder
shield again.
3. Reinstall the cylinder shield and lock it securely.
