At temperatures below + 50 °F (+10 °C), preheat carburetor as follows:

:Remove the carburetor box cover. Inside the carburetor box cover:

:Move the shutter from summer position (1) to winter position (2).

Heated air is now drawn in from around the cylinder and mixed with cold air – this helps prevent carburetror icing.

: At temperatures above + 68 °F

(+20 °C):

Return shutter to summer position. This is essential to avoid engine

running problems and overheating.

Machines with HD filter:

:Install a standard filter in place of the HD-Filter.

:Refit the carburetor box cover and tighten down the twist lock.

At temperatures below + 14 °F (-10 °C):

It is advisable to fit the optional cover plate (1128 080 7500) on the fan housing in extremely cold conditions (temperatures below + 14 °F (-10 °C), in powder or drifting snow).

The cover plate blocks off the lower slots in the fan housing to help prevent snow being sucked into the machine.

When the cover plate is fitted, the shutter in the carburetor box cover must be in the winter position.

:If your saw is very cold (frost or ice on machine), start the engine and keep it at a high idle speed (with chain brake disengaged) until it reaches normal operating temperature.

:In the event of engine running problems, first check that conditions for use of intake air preheating still apply.
