摘要
Engine-driven portable tools are widely used for different kinds of work where the surrounding conditions are very different. Large variations in temperature can cause problems for the engine, especially during low temperatures that occur during winter. The present invention reduces these problems in a simple and effective way by guiding heated air from the area adjacent to the muffler through a channel placed outside the casing to the air inlet for the engine. The cold air sucked into the engine is mixed with the heated air from the channel so that the temperature of the air mixture is increased.
