There are 8 key points in the use of torque electric wrench

所有的固定力矩扳手都要按照說明書操作，要點如下:

All fixed torque wrenches shall be operated according to the instructions, and the key points are as follows:

1. 根據需要的轉矩值，選擇相應的已通過校準的轉矩扳手，不允許使用未通過校準的轉矩扳手;

1. Select the corresponding calibrated torque wrench according to the required torque value, and it is not allowed to use the torque wrench that fails to pass the calibration;

2. 扳手應該以平衡而緩慢的力量擰動，而不是急劇的擰動。用手握住固定力矩扳手手柄的中點，將手柄垂直于扳手線方向拉動，直達到要求的力矩。

2. The wrench should be screwed with a balanced and slow force rather than a sharp one. Hold the midpoint of the handle of the fixed torque wrench by hand and pull the handle perpendicular to the wrench line until the required torque is reached.

3.不得施加大于固定扭矩扳手額定扭矩的扭矩。不要用固定扭矩扳手拆卸螺栓或螺母。

3. Do not apply a torque greater than the rated torque of the fixed torque wrench. Do not use a fixed torque wrench to remove bolts or nuts.

4、使用固定力矩扳手擰緊螺栓時，不應使用轉接頭，不得使用，必須符合下列要求:轉接頭有多種不同形狀，可以合理選用;為減小擰緊力矩誤差，適配器長度應小于固定力矩扳手長度;當連接適配器時，其線路應與扳手線在一條直線上。如果需要，可以使用帶有偏移軸的適配器，但角度不應超過15°。

4. When using the fixed torque wrench to tighten the bolt, the adapter shall not be used and must meet the following requirements: the adapter has a variety of different shapes and can be reasonably selected; In order to reduce the error of tightening torque, the length of adapter shall be less than the length of fixed torque wrench; When connecting the adapter, its line should be in line with the wrench line. If necessary, an adapter with an offset shaft can be used, but the angle should not exceed 15 °.

5. 固定力矩扳手不得作為普通扳手使用，如用于松開螺母、螺栓等;

5. The fixed torque wrench shall not be used as an ordinary wrench, such as for loosening nuts and bolts;

6、右轉力矩固定力矩扳手不能左轉，而左轉力矩固定力矩扳手不能右轉;

6. Right turn torque fixed torque wrench cannot turn left, while left turn torque fixed torque wrench cannot turn right;

7. 不要使用鍍鉻固定力矩扳手和轉移扳手來接觸鈦和合金螺栓或產品結構;

7. Do not use chrome plated fixed torque wrench and transfer wrench to contact titanium and alloy bolts or product structure;

8. 固定扭矩扳手施加的扭矩不得超過該固定扭矩扳手的額定扭矩值。

8. The torque applied by the fixed torque wrench shall not exceed the rated torque value of the fixed torque wrench.
