The invention entails a motor saw which includes a brake system for braking the motor, and which further includes a brake-system actuation arrangement comprising a lever and a positioning element which lever is held by the positioning element in a defined position and can be deflected in order to actuate the brake system. The positioning element of the actuating system engages with parts of the brake system, the positioning element limits the movement of the lever in a non-actuated brake system with a first force and the positioning element limits the movement of the lever with a second force in an actuated brake system by engaging with the brake system.

Hand guard block

A power chain saw with a drive motor arranged in a housing drives a saw chain circulating on a saw guide, wherein the saw guide is held clamped by one end transversely to its surface plane between the housing and a tightening element, and for tightening the saw chain can be displaced in the longitudinal direction L when the tightening element is detached. The power chain saw also includes detent plates arranged between the saw guide and the housing and/or between the saw guide and the tightening element, which permit the displacement of the saw guide in the tightening direction, but block it in the loosening direction of the chain. The tightening element can be embodied as chain wheel protector.
