Abstract:
A chainsaw includes a handle with a handgrip; an electric motor for endlessly moving a saw chain; a control unit for controlling rotation of the motor; and a main power switch switchable between an ON state and an OFF state. The handgrip is provided with a gripping detection device for detecting whether the handgrip is gripped by the worker, and the chainsaw is configured to, when the control unit is manipulated to deactivate the electric motor in a state in which the gripping detection device detects that the handgrip is gripped, maintain the main power switch in the ON state, and to, when the control unit is manipulated to deactivate the electric motor in a state in which the gripping detection device detects that the handgrip is not gripped, switch the main power switch to the OFF state.

Claim (Index 8):
The chainsaw as recited in  claim 2 , wherein the gripping detection device comprises:\n a gripping detection member configured to be protruded from the handgrip to take an ungripped position when the handgrip is not gripped by the worker, and to be retracted inside the handgrip to take a gripped position when the handgrip is gripped by the worker; and a position detector operable to detect whether the gripping detection member is located at the ungripped position or at the gripped position, wherein the gripping detection device is configured to detect whether or not the handgrip is gripped by the worker, depending on whether the position detector detects that the gripping detection member is located at the gripped position or that the gripping detection member is located at the ungripped position.
