Abstract
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.
