1、按所需定力數值，選擇相應的并經校驗合格的定扭矩扳手，不準使用沒有經過校驗的定扭矩扳手；
1. According to the required torque value, select the corresponding and qualified constant torque wrench, and do not use the constant torque wrench without verification;
2、要用平衡、緩慢的力扭轉扳手，不能急扭，手握住定扭矩扳手手柄中間點，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；
2. 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 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;
3、不要施加大于定扭矩扳手額定值的扭矩，不準用定扭矩扳手拆卸螺栓或螺母，定扭矩扳手只能順時針轉動；
3. Do not apply a torque greater than the rated value of the constant torque wrench. Do not use the fixed torque wrench to remove the bolt or nut. The constant torque wrench can only rotate clockwise;
4、用定扭矩扳手擰緊螺栓時，應盡可能不使用轉接器，非用不可時，必須遵守下列要求：轉接器有各種不同形狀時，可合理選用；為減少擰緊力矩誤差，轉接器長度應小于定扭矩扳手長度；連接轉接器時，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接器，但*不超過15°角。
4. When tightening bolts with constant torque wrench, the adapter should not be used as far as possible. If necessary, the following requirements must be observed: when the adapter has various shapes, it can be selected reasonably; in order to reduce the tightening torque error, the length of the adapter should be less than that of the constant torque wrench; when connecting the adapter, the center line should be in a straight line with the center line of the wrench, and the axis can also be used if necessary Offset the adapter, but * no more than 15 ° angle.
5、不允許將定扭矩扳手當做普通扳手使用，如用來擰松螺母或螺栓等；
5. Constant torque wrench is not allowed to be used as ordinary wrench, such as used to loosen nuts or bolts, etc;
6、右扭矩定扭矩扳手不能左旋，而左扭矩定扭矩扳手也不能右旋；
6. Right torque constant torque wrench can not be left-handed, and left-hand torque constant torque wrench can not be right-handed;
7、不能用鍍鉻的定扭矩扳手和轉接扳手接觸鈦及合金制的螺栓或產品結構；
7. Do not use chrome plated constant torque wrench and adapter wrench to contact titanium and alloy bolts or product structure;
8、定扭矩扳手施加的扭矩不允許超過定扭矩扳手的額定扭矩值。
8. The torque applied by the constant torque wrench shall not exceed the rated torque value of the constant torque wrench.
