A driving tool (10) includes a frame (14), a motor assembly (18) and a resilient member (1016). The motor assembly is coupled to the frame and includes an electric motor (40), a flywheel (42) driven by the electric motor, a pinch roller (50) and a driver (32) disposed between the flywheel and the pinch roller. The pinch roller is selectively movable from a first position to a second position to drive the driver into engagement with the flywheel. The driver is movable between a returned position and an extended position. The resilient member is coupled to the frame and biases the driver away from the flywheel to reduce or eliminate contact between the flywheel and the driver when the flywheel is at rest, the driver is in the returned position and the pinch roller is in the first position. A method for operating a driving tool is also provided. |
