■リバースレバーの操作方法 How to operate a reverse lever リバースレバーをR(締め)L(ゆるめ)にまわして切替えてください。 回転方向の切替えは必ずモータが停止した状態で行ってください。 リバースレバーはR側またはL側の位置にきちんと合わせてください。中間の位 置では回りません。 Please turn a reverse lever to switch R (tightening) and L (loosening). Switching rotation direction should be made when the motor is in stop condition. Place a reverse lever to the positions of R or L properly. A tool does not rotate with the reverse lever set to the intermediate position.
