扭力扳手使用注意事项：

Notes for use of torque wrench:

1、在选择扭力扳手时，要根据螺栓或螺母的尺寸来选择合适开口尺寸的扭力扳手。如果扭力扳手的开口尺寸大于螺栓或螺母的尺寸，那在使用时，容易滑脱并损伤螺件的六角。如果扭力扳手的开口尺寸太小，那就无法嵌入到螺栓或螺母中进行扭动。

1. When selecting the torque wrench, the appropriate opening size of the torque wrench should be selected according to the size of the bolt or nut. If the opening size of the torque wrench is larger than the size of the bolt or nut, it is easy to slip off and damage the hexagon of the screw. If the opening size of the torque wrench is too small, it cannot be inserted into the bolt or nut for twisting.

2、在使用扭力扳手时为防止扳手损坏和滑脱，应使拉力作用在开口较厚的一边如此才能用上力。另外在使用扭力扳手时，要注意开口不能出现“八”字形，以免损坏螺母和扳手。

2. When using the torque wrench, in order to prevent the wrench from damage and slippage, the pulling force should act on the thicker side of the opening so as to use the force. In addition, when using the torque wrench, it should be noted that the opening should not appear "eight" shape, so as to avoid damaging the nut and wrench.

3、扭力扳手是按人手的力量来设计的，人手力量越大，扭力扳手在旋转螺纹、螺母时的力量越大。如果遇到较紧的螺纹件，用扭力扳手也不能使其松动的话，切记不能用捶打工具锤击扳手，以免损坏扳手，可以适当调整扳手的用力方向，找到合适的发力点。另外还要注意的是除了套筒扳手能套装加力杆，其他扳手都不能套装加力杆，扭力扳手也不能。遇到无法拧动的螺纹紧固件，不能胡乱给扭力扳手加装加力杆，以防损坏扳手或螺纹连接件。

3. The torque wrench is designed according to the strength of human hands. The greater the strength of human hands, the greater the force of torque wrench when rotating threads and nuts. If a tight threaded part cannot be loosened with a torque wrench, remember not to hammer the wrench with a hammer tool, so as to avoid damaging the wrench. The force direction of the wrench can be adjusted appropriately to find the appropriate force point. In addition, it should be noted that in addition to the socket wrench can be equipped with an afterburner, no other wrench can be equipped with an afterburner, nor can a torque wrench. In case of screw thread fastener that cannot be turned, do not add force bar to torque wrench randomly to prevent damage to wrench or threaded connector.

4、扭力扳手一般都带有预设扭矩数值和声响的装置，当紧固件的拧紧扭矩达到预设数值时，扭力扳手能自动发出讯号“卡嗒”声，同时伴有明显的手感振动，这表示扭力扳手已经将紧固件松好。将扭力扳手从紧固件上取下后，扳手各相关零件能自动复位。

4. The torque wrench is usually equipped with a device with preset torque value and sound. When the tightening torque of the fastener reaches the preset value, the torque wrench can automatically send out a signal "click" sound, accompanied by obvious hand vibration, which indicates that the torque wrench has loosened the fastener. After the torque wrench is removed from the fastener, the relevant parts of the wrench can be reset automatically.

5、扭力扳手一般是用来旋转螺栓或螺帽的，扳转时应该使用拉力，推转扳手极易发生危险。在使用时一定要注意这点。另外扭力扳手可以用来松紧螺栓，螺栓旋紧前应先将螺栓清洁并上润滑油。

5. The torque wrench is generally used to rotate the bolt or nut. The pulling force should be used when turning, and the pushing wrench is easy to cause danger. This must be paid attention to when using. In addition, the torque wrench can be used to loosen the bolt, and the bolt should be cleaned and lubricated before tightening.

6、在使用扭力扳手旋紧螺栓时，应均匀使力，不得利用冲击力。简单来说就是不要用锤击工具来锤击扳手，使其在短时间内获得冲击力，从而带动整只扳手旋转，使扳手将螺栓旋紧，这种做法容易损坏扳手。

6. When using the torque wrench to tighten the bolt, the force should be evenly applied, and the impact force should not be used. In short, do not use hammering tools to hammer the wrench, so that it can obtain impact force in a short time, so as to drive the whole wrench to rotate, so that the wrench will tighten the bolt, which is easy to damage the wrench.

7、如果长期不用扭力扳手，建议把扭力扳手的调节标尺刻线退扭矩小数值处，这样可以延长扳手的使用寿命。

7. If the torque wrench is not used for a long time, it is suggested that the scale marking of the torque wrench should be retreated to the small value of torque, so as to prolong the service life of the wrench.
