Torque wrench maintenance and precautions
Nowadays, torque wrenches are more and more popular among users, and they are not only convenient to use, but also have accurate torque values. But there are also many people who don't know how to do maintenance, so Xiao Bian is here to explain the methods to you, hoping to help the majority of users.
Torque wrench maintenance method:
(1) After using the torque wrench, the torque value must be adjusted to the minimum value.
(2) Please use "preload" before using the torque wrench.
(3) Do not overload the torque wrench.
(4) Do not use any extension rods other than the original.
(5) Do not use the torque wrench as a tool.
(6) Please keep the torque wrench clean and complete.
(7) Check the torque wrench periodically.
(8) The screw disassembly torque value is approximately 1.5 times the tightening torque value.
Precautions
1. When using a torque wrench, load it slowly and slowly. Do not yank or press it to avoid overload, resulting in inaccurate output torque. After reaching the preset torque, stop loading.
2, can not use the preset type torque wrench to remove the bolt or nut.
3. It is forbidden to add a sleeve to extend the arm at the end of the torque wrench to prevent damage to the torque wrench.
4. Adjust the required torque as needed, and confirm that the adjustment mechanism is in locked state before use.
5. When the preset type torque wrench is used, it should be adjusted to the minimum torque so that the force measuring spring can be fully relaxed to prolong its life.
6, should avoid moisture intrusion preset torque wrench to prevent parts rust.
7. The size of the opening of the torque wrench must be consistent with the size of the bolt or nut. The wrench opening is too large to slip off and damage the hexagon of the screw. In the maintenance of imported vehicles, attention should be paid to the selection of the metric wrench.
8. Selection principles for various types of wrenches. Generally, socket wrenches are preferred. Followed by plum wrenches, open-end wrenches are again used. Finally, movable wrenches are selected.
9. In order to prevent the wrench from being damaged and slipping off, the pulling force should be applied to the thick side of the opening. This should be paid attention to in particular for the larger movable wrenches, so as to prevent the opening from appearing “eight†shape and damaging the nuts and wrenches.
Maintenance and maintenance are very important, so please do not take it lightly. If you maintain it well, you can extend the service life of the product and save costs. Why not do it!
