1.力矩扳手只能用作安装紧固件(螺栓、螺母)时测量其安装力矩使用，绝不能作为拆卸工具去拧松已拧紧的紧固件。不能敲打、磕碰或作它用。使用时轻拿轻放，不许任意拆卸与调整。
1. The torque wrench can only be used to measure the installation torque when installing fasteners (bolts and nuts), and must not be used as a removal tool to loosen the tightened fasteners. It shall not be knocked, knocked or used for other purposes. Handle with care during use, and do not disassemble and adjust arbitrarily.
2.在使用扭矩紧固件的场合尽可能带上护目镜，这样可以在突发情况下保护操作者的眼部。
2. When torque fasteners are used, wear goggles as much as possible, so as to protect the operator's eyes in case of emergencies.
3.为了保证工作人员正确使用和测量值的准确，防止对工具、设备的损害，必须确保所施加的扭矩值在扭矩设备的范围内，在使用扭矩设备前请正确了解扳手的大量程，不能乱用。选择扳手的条件好以工作值在被选用扳手的量限值20%～80%之间为宜。
3. In order to ensure the correct use and accuracy of measured values by staff and prevent damage to tools and equipment, it is necessary to ensure that the applied torque value is within the range of torque equipment. Before using torque equipment, please correctly understand the large range of wrench and do not use it indiscriminately. The conditions for selecting the wrench are good, and the working value should be between 20% ~ 80% of the quantity limit of the selected wrench.
4.紧固时应使用正确的接头，否则会导致施加的扭矩出现人为误差。接头应接触紧密，有足够硬度。
4. Correct joints shall be used during tightening, otherwise human error will occur in the applied torque. The joint shall be in close contact and have sufficient hardness.
5.从加载的考虑，在扳手手柄上尽量使用拉力(力向上)而不是推力(力向下)。要调整操作姿势，防止操作失败时人员跌倒。
5. For the safety of loading, try to use tension (force up) instead of thrust (force down) on the wrench handle. Adjust the operation posture to prevent personnel from falling when the operation fails.
6.使用前后，扳手存放盒内，不可到处放置。使用后，擦拭干净放入盒内。定力扳手使用后要注意将示值调节到小值处，以保证其准确度及使用寿命。否则，往往会使定力扳手提前失效或损坏。据我们多年的统计，许多定力扳手的非正常性损坏就是由这个原因引起的。这是由于扳手内的弹簧如果经常处于压缩状态，不能松弛，就会造成弹簧发生形变，而这种情况下的扳手是不能修复的(除非更换弹簧)。所以在实际工作中，无论是使用或保存，都一定要注意这一点。
6. Before and after use, the wrench shall be stored in the box and shall not be placed everywhere. After use, wipe it clean and put it into the box. After use, pay attention to adjust the indicated value to the small value to ensure its accuracy and service life. Otherwise, it will often make the torque wrench invalid or damaged in advance. According to our statistics for many years, the abnormal damage of many torque wrenches is caused by this reason. This is because if the spring in the wrench is often compressed and cannot be relaxed, it will cause permanent deformation of the spring, and the wrench in this case cannot be repaired (unless the spring is replaced). Therefore, in practical work, we must pay attention to this point whether it is used or saved.
7.使用时应严禁在尾部加套管或长柄，有专用配套附件(长柄或套管)除外。力必须加在手柄尾端，使用时用力要均匀、缓慢。要正确区分扳手柄被锁住了还是扳手润滑不好这两种情况，以使扳手调节到需要的扭矩值。定力扳手锁环处于“锁住”时，不要强行转动手柄。当锁环处于“不锁住”时，调节数值，工作值选定后，使锁环处于“锁住”后进行工作。
7. It is forbidden to add casing or long handle at the tail during use, except for special accessories (long handle or casing). The force must be applied at the end of the handle, and the force shall be uniform and slow during use. It is necessary to correctly distinguish between the two situations that the wrench handle is locked or the wrench is not well lubricated, so as to adjust the wrench to the required torque value. Do not forcibly turn the handle when the locking ring of the torque wrench is "locked". When the lock ring is in "not locked", adjust the value. After the working value is selected, make the lock ring in "locked" and work.
8.如果扳手较长时间未用过，(使用前)应先预加载几次，使内部工作机构的润滑油均匀流遍，这点无论对于使用还是检定都是很重要的，但常常会被忘记。
8. If the wrench has not been used for a long time, it should be preloaded several times (before use) to make the lubricating oil of the internal working mechanism flow evenly. This is very important for use and verification, but it is often forgotten.
