What points should be paid attention to when using the constant torque electric wrench. Customers should select the corresponding and qualified constant torque electric wrench according to the fixed force value of the constant torque electric wrench required by the customer. It is not allowed to use the constant torque electric wrench without verification, which is considered from the aspect of safety performance. The constant torque electric wrench in use needs to pay attention to the following six points:

1、要用平衡、缓慢的力扭转扳手，不能急扭，手握住定扭矩电动扳手手柄中间点，垂直于扳手线拉动手柄，直到达到所要求的力矩为止，不允许随意手握根部和端点;

1. It is necessary to use balanced and slow force to twist the wrench. Do not turn it quickly. Hold the middle point of the handle of the constant torque electric wrench and pull the handle perpendicular to the center line of the wrench until the required torque is reached. It is not allowed to hold the root and end points at will;

2、不要施加大于定扭矩电动扳手额定值的扭矩，不准用定扭矩电动扳手拆卸螺栓或螺母，定扭矩电动扳手只能顺时针转动;

2. Do not apply a torque greater than the rated value of the constant torque electric wrench. Do not use the fixed torque electric wrench to remove the bolt or nut. The fixed torque electric wrench can only rotate clockwise;

3、用定扭矩电动扳手拧紧螺栓时，应尽可能不使用转接器，非用不可时，必须遵守下列要求：转接器有各种不同形状时，可合理选用;为减少拧紧力矩误差，转接器长度应小于定扭矩电动扳手长度;连接转接器时，其线应和扳手线成一条直线，若需要也可使用轴线偏移的转接器，但不超过15°角。

3. When the fixed torque electric wrench is used to tighten the bolts, the adapter shall not be used as much as possible, and the following requirements shall be observed when it is not used: when the adapter has different shapes, it can be selected reasonably; in order to reduce the error of tightening torque, the length of the adapter shall be less than the length of the fixed torque electric wrench; When connecting the adapter, the center line should be in a straight line with the center line of the wrench. If necessary, the adapter with axis offset can be used, but the maximum angle should not exceed 15 degrees.

4、不允许将定扭矩电动扳手当做普通扳手使用，如用来拧松螺母或螺栓等;右扭矩定扭矩电动扳手不能左旋，而左扭矩定扭矩电动扳手也不能右旋;

4. It is not allowed to use the constant torque electric wrench as an ordinary wrench, such as for loosening nuts or bolts; the right torque constant torque electric wrench cannot be left-handed, and the left torque constant torque electric wrench cannot be right-handed;

5、不能用镀铬的定扭矩电动扳手和转接扳手接触钛及合金制的螺栓或产品结构;

5. Do not use chrome plated constant torque electric wrench and adapter wrench to contact titanium and alloy bolts or product structure;

6、要提醒大家，也是很多朋友都会忽略的：定扭矩电动扳手施加的扭矩不允许超过定扭矩电动扳手的额定扭矩值。

6. Finally, we should remind you that many friends will ignore: the torque applied by the constant torque electric wrench is not allowed to exceed the rated torque value of the constant torque electric wrench.
