辨别扭力大小，需要你把锂电扳手开机一下，然后你观察手柄下功能键旁亮起的小灯，如果亮在大扭力位置，说明锂电扳手处于大扭力。如果在小扭力处灯亮，那么说明处于小扭力。判断电动扳手的扭力大小，需要在开机运转的时候，看开关手柄下的功能键，上面有大扭力和小扭力提示。如果灯亮在大扭力，说明这电板手扭力处于大，如果在小扭力灯亮，说明处于小扭力。
To identify the torque, you need to turn on the lithium wrench, and then observe the small light that lights up next to the function key under the handle. If it lights up at the high torque position, it means that the lithium wrench is at the high torque. If the light is on at small torque, it means it is at small torque. To judge the torque of the electric wrench, you need to look at the function key under the switch handle when starting and running. There are big torque and small torque prompts on it. If the light is on at high torque, it means that the electric wrench is at high torque. If the light is on at low torque, it means that it is at low torque.

扭剪扳手厂家认为，扭力预设时的一些注意事项还需多多了解，比如：预设扭力值时，将板子手柄上的锁定环下拉，同时转动手柄，调节标尺主刻度线和微分刻度线数据所需扭力值。调节好后，松开锁定环，手柄自动锁定。在板子方榫上装上相应规格套筒，并套住紧固件，再在手柄上缓慢用力。施加外力时须按标明的箭头方向。当拧紧到发出信号"卡嗒"一声（已达到预设扭力值），停止加力。
In addition, some precautions for torque presetting need to be understood. For example, when presetting the torque value, pull down the locking ring on the handle of the board, and turn the handle at the same time to adjust the data of the main scale and differential scale of the scale to the required torque value. After adjustment, release the locking ring and the handle will automatically lock. Install a sleeve of corresponding specification on the square tenon of the board, cover the fastener, and then slowly apply force on the handle. When applying external force, follow the indicated arrow direction. When the screw is tightened to a signal "click" (the preset torque value has been reached), stop the afterburner.
很大规格扭力扳手使用时，可外加接长套杆以便操作省力。如长期不用，调节标尺刻线退扭力小数据处。
When using a large torque wrench, an extension sleeve can be added to save labor. If it is not used for a long time, adjust the scale line back to the small torque data.
使用扭力扳手时，应均衡缓慢地加载，切不可猛拉猛压，以免造成过载，导致输出扭力失准。在达到预臵扭力后，应停止加载。所选用的扭力扳手的开口尺寸须与螺栓或螺母的尺寸一致，各类板子的选用原则，一般优先选用套筒板子，其次为梅花板子，再次为开口板子，后选活动板子。
When the torque wrench is used, it should be loaded evenly and slowly, and should not be pulled and pressed violently, so as to avoid overloading and inaccurate output torque. Stop loading after reaching the preset torque. The opening size of the selected torque wrench must be consistent with the size of the bolt or nut. The selection principle of various types of plates is generally to choose sleeve plate first, then plum plate, then open plate, and then movable plate.
