扭力扳手是一種精 密控制螺栓和螺母鎖緊力矩的專用工具，應按照下列要求正確使用:
Torque wrench is a special tool for precisely controlling the locking torque of bolts and nuts. It should be used correctly according to the following requirements:
1、不能使用預置式扭力扳手去拆卸螺栓或螺母。
1. Do not use a preset torque wrench to remove bolts or nuts.
2、嚴禁在扭力扳手尾端加接套管延長力臂，以防損壞扭力扳手。
2. It is forbidden to add a sleeve at the end of the torque wrench to extend the force arm to prevent damage to the torque wrench.
3、根據(jù)需要調節(jié)所需的扭矩，并確認調節(jié)機構處于鎖定狀態(tài)才可使用。
3. Adjust the required torque as required and confirm that the adjusting mechanism is locked before use.
4、使用扭力扳手時，應平衡緩慢地加載，切不可猛拉猛壓，以免造成過載，導致輸出扭矩失準。在達到預置扭矩后，應停止加載力量。
4. When using the torque wrench, it shall be loaded slowly and balanced, and shall not be pulled and pressed violently, so as to avoid overload and inaccurate output torque. After reaching the preset torque, the loading force shall be stopped.
5、預置式扭力扳手使用完畢，應將其調小扭矩，使測力彈簧充分放松，以延長其壽命。
5. After the preset torque wrench is used, it shall be adjusted to a small torque to fully relax the force measuring spring, so as to prolong its service life.
6、應避免水分侵入預置式扭力扳手，以防零件銹蝕。
6. Avoid moisture intrusion into the preset torque wrench to prevent parts from rusting.
7、所選用的扭力扳手的開口尺寸必須與螺栓或螺母的尺寸相符合，扳手開口過大易滑脫并損傷螺件的六角，各類扳手的選用原則，一般優(yōu)先選用套筒扳手，其次為梅花扳手，再次為開口扳手，選活動扳手。
7. The opening size of the selected torque wrench must be consistent with the size of the bolt or nut. If the opening of the wrench is too large, it is easy to slip off and damage the hexagon of the screw. Generally, socket wrench is preferred, followed by ring wrench, open-ended wrench and movable wrench.
8、為防止扳手損壞和滑脫，應使拉力作用在開口較厚的一邊，這一點對受力較大的活動扳手尤其應該注意，以防開口出現(xiàn)“八”字形，損壞螺母和扳手。
8. In order to prevent the wrench from being damaged and slipping, the pulling force shall act on the thicker side of the opening, which shall be paid special attention to the adjustable wrench with large force, so as to prevent the "eight" shape of the opening from damaging the nut and wrench.
9、扭力扳手是按人手的力量來設計的，遇到較緊的螺紋件時，不能用錘擊打扳手；除套筒扳手外，其它扳手都不能套裝加力桿，以防損壞扳手或螺紋連接件。
9. The torque wrench is designed according to the force of human hands. When encountering tight threaded parts, the wrench cannot be hit with a hammer; Except for the socket wrench, other wrenches shall not be sleeved with a booster rod to prevent damage to the wrench or threaded connector.
10、扭力扳手使用時，當聽到“啪”的一聲時，此時是合適的。
10. When the torque wrench is used, it is appropriate to hear a "snap" sound.
備注：
remarks:
1、用途：扭力扳手為旋轉螺栓或螺帽的工具。
1. Purpose: torque wrench is a tool for rotating bolts or nuts.
2、用法：扭力扳手扳轉時應該使用拉力，推轉扳手極易發(fā)生危險。
2. Usage: tension should be used when turning the torque wrench. Pushing the wrench is very dangerous.
3、扭力扳可用于松緊螺栓，螺栓旋緊前應先將螺栓清潔并上潤滑油。
3. The torque wrench can be used to loosen the bolts. The bolts should be cleaned and lubricated before tightening.
4、使用扭力扳手旋緊螺栓時應均勻使力，不得利用沖擊力。
4. When tightening bolts with torque wrench, the force shall be uniform, and the impact force shall not be used.
