Knot structural composition

doper consists of four parts: Handle, gun head, barrel and handle. The oil nozzle can be divided into two types: pointed and flat nozzle. The accessories are divided into two types: Hose and hard tube. The interior of barrel is made of packing leather, spring, steel ball, exhaust screw, etc.

Usage skills

major faults

first, packing leather is not good. This is a common problem of almost all domestic oil guns. However, it is no wonder that the structure of an oil gun is relatively complicated compared with that of ordinary tools. It costs more than ten yuan to sell it, probably it can only be so;

the second is that the oil pressing mechanism is not good, but if there is no problem with the spring and the check ball, it probably cannot be repaired.

Third, there are some faults in use. Many faults in use are caused by your own operation, so you can find ways to avoid them. For example, once a few grains of sand are mixed into the butter, and at this time, if you use a pointed nozzle, you must be so angry that you can only relieve your hatred by throwing the oil gun away, and it is absolutely not good for the equipment, but in fact, most of these things are caused by themselves. Therefore, we must keep the butter used clean, do not use dirty tools to refuel, and cover the oil container in time.

Response measures

1. If there is a hard pull rod, you can pull the rod several times to make the air inside grease mixing and reducing the volume of a single bubble may solve the problem, but the effect is not very good every time.

2. The most effective method is the deflation method, but it needs the support of hardware. Some guns have the design of exhaust ports. When you slowly open the exhaust screws, the air inside will come out.

3. The last one is the final skill, and it has been tried and tested repeatedly, when you think there is gas in it and you can't play it out, just turn the wire mouth combined with the oil gun body and the pump body for a few times or back and forth (it is better to turn the side pressure) to ensure your success. The reason is not difficult, that is, when you rotate, the gas bubble inside is actually rotating to another part, and the original part is filled with lubricating oil, so the problem is solved.
