Claim 4:
5. An electric work machine including:
an electric motor configured to receive power from a battery as a drive power source;
a hydraulic actuator having, as a hydraulic pressure source, a hydraulic pump configured to be driven by the electric motor; and
a power supply port configured to connect/disconnect with a power supply cable; and
wherein:
in the case where the power supply cable for supplying electric power from an external power supply is connected to the power supply port and rotation of the electric motor is stopped, the battery can be charged from the external power supply, and
in the case where the power supply cable for supplying the electric power from the external power supply is connected to the power supply port, where the rotation of the electric motor is stopped, and where a cut-off lever for restricting an operation of the hydraulic actuator is operated so as to restrict the operation of the hydraulic actuator, the battery cannot be charged from the external power supply.
