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 1):
A chainsaw comprising:\n a housing; at least one handle coupled to the housing, each of the at least one handle including a handgrip to be gripped by a worker using the chainsaw; a guide bar coupled to the housing in such a manner as to protrude forwardly from the housing, the guidebar formed in an elongate plate shape having an outer periphery; a saw chain slidably provided around the outer periphery of the guide bar in such a manner as to be endlessly moved along the outer periphery; an electric motor provided inside the housing and operable to endlessly move the saw chain; an electric power supply; a main power switch provided electrically between the electric power supply and the electric motor, the main power switch being switchable between an ON state for enabling electric power feeding from the electric power supply to the electric motor, and an OFF state for disabling the electric power feeding; a control unit for controlling the electric power feeding from the electric power supply to the electric motor in a state in which the main power switch is switched to the ON state, to thereby control rotation of the electric motor; and at least one gripping detection device provided in the handgrip and operable to detect whether or not the handgrip is gripped by the worker.
