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 constant force value, select the corresponding constant torque wrench that has been verified to be qualified. It is not allowed to use the constant torque wrench that has not been verified;
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. Torque the wrench with a balanced and slow force instead of a quick torque. Hold the middle point of the handle of the constant torque wrench with your hand 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 constant torque wrench to remove bolts or nuts. 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 the bolts with a constant torque wrench, the adapter shall not be used as far as possible. If it is not necessary, the following requirements must be observed: when the adapter has various shapes, it can be reasonably selected; In order to reduce the error of tightening torque, the length of adapter should be less than the length of fixed torque wrench; When connecting the adapter, the center line should be in line with the center line of the wrench. If necessary, the adapter with axis offset can also be used, but the maximum angle should not exceed 15 °.
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. It is not allowed to use the fixed torque wrench as an ordinary wrench, such as to loosen nuts or bolts;
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. The right torque constant torque wrench cannot turn left, and the left torque constant torque wrench cannot turn right;
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. Chrome plated constant torque wrench and adapter wrench shall not be used to contact titanium and alloy bolts or product structures;
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.
