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、緩慢的力扭轉(zhuǎn)扳手，不能急扭，手握住定扭矩電動扳手手柄中間點，垂直于扳手線拉動手柄，直到達到所要求的力矩為止，不允許隨意手握根部和端點;

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電動扳手額定值的扭矩，不準用定扭矩電動扳手拆卸螺栓或螺母，定扭矩電動扳手只能順時針轉(zhuǎn)動;

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、用定扭矩電動扳手擰緊螺栓時，應盡可能不使用轉(zhuǎn)接器，非用不可時，必須遵守下列要求：轉(zhuǎn)接器有各種不同形狀時，可合理選用;為減少擰緊力矩誤差，轉(zhuǎn)接器長度應小于定扭矩電動扳手長度;連接轉(zhuǎn)接器時，其線應和扳手線成一條直線，若需要也可使用軸線偏移的轉(zhuǎn)接器，但不超過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、不允許將定扭矩電動扳手當做普通扳手使用，如用來擰松螺母或螺栓等;右扭矩定扭矩電動扳手不能左旋，而左扭矩定扭矩電動扳手也不能右旋;

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、不能用鍍鉻的定扭矩電動扳手和轉(zhuǎn)接扳手接觸鈦及合金制的螺栓或產(chǎn)品結(jié)構(gòu);

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，也是很多朋友都會忽略的：定扭矩電動扳手施加的扭矩不允許超過定扭矩電動扳手的額定扭矩值。

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.
