请务必使用220V的电源。
Please be sure to use a 220V power supply.
正确连接电源延长导线。（否则会产生电压降，使扭矩降低电机有效转速降低，使电机发热使转子漆包线短路）
Connect the power extension wire correctly. (Otherwise, a voltage drop will occur, causing a decrease in torque and the effective speed of the motor, causing the motor to heat up and short-circuit the rotor enameled wire)
延长线导体公称面积在3.50平方毫米时，更短为60米。
When the nominal area of the extension line conductor is 3.50 square millimetre, the minimum length is 60 meters.
请使用原装插座接地线有漏电保护器设置。（否则会因空气潮湿而麻手或有漏电危险）
Please use the original socket grounding wire with a leakage protector setting. (Otherwise, there may be numbness or electric leakage due to humid air)
请不要在电动扳手工作时用手触摸红色反力臂。（否则会挤伤手指）
Please do not touch the red reaction arm with your hands while the electric wrench is working. (Otherwise, it may crush your fingers)
请在开始使用扭矩型电动扳手之前预热几分钟。（否则会使扭矩达不到标定扭矩值）
Please preheat for a few minutes before starting to use a torque type electric wrench. (Otherwise, the torque may not reach the calibrated torque value)
当控制器板上的绿灯亮时说明是正常操作，可以继续工作；当红灯闪亮时说明有错误操作，请检查。
When the green light on the controller board is on, it indicates normal operation and can continue working; When the red light flashes, it indicates an incorrect operation. Please check.
当调节正反转时，请务必把旋转扳机旋转到位。（否则会打坏反正转齿轮）
When adjusting the forward and reverse rotation, be sure to rotate the rotary trigger in place. (Otherwise, it will damage the reverse gear)
当扳手拧紧螺栓停止时，请不要再次开机拧紧。（否则会冲坏行星齿轮，这样螺栓扭矩会增大）
When the wrench stops tightening the bolt, do not turn on the machine again to tighten it. (Otherwise, the planetary gear will be damaged, which will increase the bolt torque)
请及时更换碳刷，使用原厂碳刷。磨损不能短于6毫米。（否则会因碳刷弹簧压力不够而产生电火花烧毁转子）
Please replace the carbon brush in a timely manner and use the original carbon brush. Wear should not be less than 6 millimeters. (Otherwise, electric sparks may burn the rotor due to insufficient pressure on the carbon brush spring)
