It is advisable to fit the intake air preheating kit* if you use your saw in extremely cold conditions (temperatures below -10 ° C /+14 ° F, in powder or drifting snow). When fitted, the kit ensures that only heated air is drawn in from around the cylinder - it prevents air filter and carburetor icing. The rotary shutter for carburetor preheating must be fully open when the intake air preheating kit is fitted. 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.
