ABSTRACT:
The motor saw has a rear handle connected to the body by vibration-damping elements with rubber or steel springs, and the throttle of the carburetor and the throttle control are connected by a rigid wire link. The throttle control bearing includes a shaft mounted in oblong holes to give a longitudinal play so that when the handle is moved with respect to the body, the throttle control can move the corresponding distance in the bearing without influencing the setting of the throttle in the carburetor in its idle position. When the handle is moved in this position, and a throttle opening is desired by moving the throttle control, a sliding part at the rear end of the throttle will contact a curved partition in the handle and push the throttle control to an advanced position, after which an opening of the throttle takes place by further movement of the throttle control.
