扭剪型电动扳手在使用时会有不同的细小问题出现，一般情况下，我们都能自己处理，那么我们来看下，具体问题应该如何处理：
There are different small problems in the use of torsional shear electric wrench. Generally, we can deal with them by ourselves. Let's see how to deal with the specific problems:
一般地，在使用过程中，如果发现螺栓梅花头吐不出来，说明扳手的套筒已经磨损太厉害了，梅花头卡在里面了，这时候应该更换新的套筒。
Generally, if it is found that the bolt Torx head cannot spit out during use, it indicates that the socket of the wrench has been worn too much and the Torx head is stuck in it. At this time, a new socket should be replaced.
一般地，在使用过程中，如果发现电机下面有火花，说明该换碳刷了。如果火花非常大，说明电机转子已经烧了。
Generally, if sparks are found under the motor during use, it indicates that it is time to replace the carbon brush. If the spark is very large, the motor rotor has been burned.
一般地，在使用过程中，如果发现电机转，而套筒不转，这说明某个齿轮磨秃了。
Generally, in the process of use, if it is found that the motor rotates and the sleeve does not rotate, it indicates that a gear is bald.
一般地，在使用过程中，如果发现电机声音”嗡嗡...”地响，可能是电机轴承坏了。
Generally, if the motor sounds "buzzing..." during use, the motor bearing may be broken.
一般地，在使用过程中，如果发现电机声音异常，或者机械部分声音“霹雳咔嚓...”异响，那么应该马上停止使用，联系厂家销售代表。
Generally, if the motor sounds abnormal or the mechanical part sounds "Thunderbolt click..." during use, it should be stopped immediately and contact the manufacturer's sales representative.
一般地，如果通电后，而电机不转，请先检查电源及电源线和开关，确保线路部分正常。再检查碳刷是否短缺。再检查电机部分。
Generally, if the motor does not rotate after power on, please check the power supply, power line and switch to ensure that the line is normal. Then check whether there is a shortage of carbon brushes. Finally, check the motor part.
一般地，维修时，拿到工具后，先外观检查，判断线路部分、碳刷、各个配件是否正常。再通电检查。
Generally, during maintenance, after getting the tools, check the appearance first to judge whether the circuit part, carbon brush and various accessories are normal. Re energize and check.
如果要打算拆开机器，请先断电，并取出碳刷，再开始拆机。
If you want to disassemble the machine, please cut off the power and take out the carbon brush before disassembling the machine.
