ABSTRACT:
A combustion-powered driving tool for driving nails or other fasteners in which the starting characteristics of a motor in the tool are improved by varying the amount of voltage applied to the motor when starting the motor and during normal operations so that the motor is driven to reach the rotational speed required in normal operations quickly. Therefore, the combustion-powered driving tool does not require the use of an expensive low-inertia motor, but can use a relatively inexpensive core-type motor or the like with inferior starting characteristics, while improving the work efficiency and user-friendliness of the combustion-powered driving tool.
