Combustion type power tool having avoiding unit for avoiding overheating to mechanical components in the tool |
摘要 |
A combustion type power tool capable of avoiding damage to seal members and a housing to prolong a service life, and capable of enhancing operability and workability. Temperature elevation of a combustion chamber frame due to combustion of a mixture of combustible gas and air is detected by a temperature sensor disposed in a housing. If the detected temperature exceeds a preset temperature, ignition of an ignition plug is prohibited by a prohibiting unit in spite of ON operation of a trigger switch. In this state, alarming is performed by a display to notify the user of inoperable sate of the tool. Similar control can be made when the temperature sensor is disposed at a cylinder, an exhaust cover and the housing.
