ABSTRACT Disclosed is a portable power chain saw with a safety device to pro- tect against kick-back or recoil movements of the saw. The power chain saw has a handle, a finger guard which is arranged between the handle and the saw chain and acts as an inertial mass, as well as a blocking device which actuates the safety device at the beginning of a kick-back movement. The chain saw also in- cludes a monitoring device, which responds to an operating condition of the chain saw impairing the safety of use thereof by an operator, and which is in effective connection with an indicating device. An auxiliary device may addi- tionally be provided for actuating the safety device, and this auxiliary device is releasable by the monitoring device and ultimately brings the saw to a stand- still.
