How to save the wrench?

Don’t strike the wrench continuously, there should be a suitable interval for more than ten times, and it should be cleared in time. Except for the knocked part of the tool, continue to use it after being stained with the knocked debris. Knock and smash tools should be cleared in time during actual operation. In addition to on-site debris and oxides corroded by the working surface, prevent a third party from impacting and causing an explosion.

All tools should be cleaned of oil stains on the surface before use. After use, wipe off the surface oil stains and deposits. Store them in a dry place. Store them in isolation from corrosive materials. They should be stored without applying a proper amount of lubricating oil for a long time.

Wrench tools should not be used excessively, and should not be used to extend the arm of force with casing or binding other metal bars, and to strike with a hammer (except for striking wrenches), so as not to cause breakage and deformation due to overload and affect normal use. When using a tool, you should choose its variety and specifications reasonably according to your needs. It should not be replaced by a small one, and it cannot be used as a steel tool. It should be pointed out that when using adjustable wrenches, pipe wrenches, and open-ended wrenches, pay attention to the force direction requirements and do not arbitrarily twist. When using a tool with a blade, the hardness of the workpiece itself should be measured first, when the hardness is lower than the tool When it is hard, it can be operated, when it is at the hardness of the tool, it is forbidden to use it. When the workpiece is tightened by motor, fixed semi-permanently or corroded, and no other measures are taken before using the hand tool, it should be prohibited to use it to avoid damage to the tool.

When the tool collides with rocks, sparks may be generated. Putting the rock in the water and then operating it can reduce the possibility of accidents. If the powder particles of aluminum, magnesium and their alloys slightly adhere to the surface of the rusty (iron oxide) steel, they will be exposed to hard objects or even The impact of hard rubber or plastic may cause a violent exothermic thermite reaction, which is likely to detonate. When tools are used to hit or rub a hot steel workpiece coated with aluminum paint, there may be very dangerous accidents.
