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 3):
The chainsaw as recited in  claim 2 , wherein the at least one handle comprises a first handle and a second handle, and the at least one gripping detection device comprises a first gripping detection device and a second gripping detection device;\n the first handle having a first handgrip to be gripped by one hand of the worker using the chainsaw, the second handle having a second handgrip to be gripped by the other hand of the worker using the chainsaw, the first handgrip being provided with the first gripping detection device operable to detect whether the first handgrip is gripped by the worker, the second handgrip being provided with the second gripping detection device operable to detect whether or not the second handgrip is gripped by the worker, and the interlocking device is configured to, when the control unit is manipulated to stop the rotation of the electric motor in a state in which each of the first gripping detection device and the second gripping detection device detects that a corresponding one of the first handgrip and the second handgrip is gripped by the worker, maintain the main power switch in the ON state, and to, when the control unit is manipulated to strop the rotation of the electric motor in a state in which at least one of the first gripping detection device and the second gripping detection device detects that a corresponding one of the first handgrip and the second handgrip is not gripped by the worker, switch the main power switch to the OFF state.
