Abstract: A working machine according to one aspect of the present disclosure comprises an operation rod, a leading end unit, a rear end unit, and a drive permitter. The operation rod is configured to be transformable between an extended state and a non-extended state. The leading end unit is provided at one end of the operation rod. The leading end unit comprises a motor configured to drive a working element. The rear end unit is provided at the other end of the operation rod. The rear end unit comprises a controller configured to control driving of the motor. The drive permitter is configured to permit driving of the motor when the operation rod is in the extended state and not to permit driving of the motor when the operation rod is in the non-extended state.

Abstract: An adapter connects a plurality of first battery packs, each having a nominal voltage of about 18-36 volts, in series to an power tool having a rated voltage that is 36 volts or higher. The power tool includes a second battery interface configured to removably attach a second battery pack. The adapter includes a plurality of first battery interfaces configured to removably attach the plurality of first battery packs and having a different physical configuration than the second battery interface. A connector of the adapter is configured to be removably attached to the second battery interface. A plurality of visual indicators is disposed on the adapter such that they have the same or substantially the same illumination direction and they visually indicate at least a level of charge of each of the first battery packs attached to the adapter.
