The main failure of the grease gun:

First, the skin is not good. This is almost a common problem with all domestic oil guns. I don't know why China's spacecraft can go to heaven today. Why can't even do a good oil gun, but I know this is not difficult. However, it is no wonder that the structure of a grease gun is more complicated than that of a normal tool. Selling it for a dozen dollars is probably only the case; but I want to do something with it or something I bought. If you use it, it is not a waste of national resources. So I don't usually use a domestic oil gun because it can't be used or can't be repaired (for this reason, I often have a famous saying: China does not have a grease gun is useful; no one has three feet that are the same length) . Second, the oil pressure mechanism is not good, but if the spring and the steel ball are no problem, it is probably impossible to repair. The third is some faults in use. Many of the faults in use are caused by their own operations. We can find ways to avoid them. For example, sand, once you mix a few grains of sand in the butter, and you use a pointed nozzle at this time, then you can guarantee that you are not angry with the oil gun to hate, and it is absolutely not good for the equipment, however In fact, most of this is caused by myself. Therefore, we must keep the butter used clean, do not use unclean tools to refuel, and drain the oil container in time.

Some measures taken against the fault:

1. If there is a hard rod, you can pull the rod several times, so that the air inside can be mixed with the grease. Reducing the volume of a single bubble may solve the problem, but the effect is not good every time.

2, the most effective method is the deflation method, but this requires hardware support, some gun body has a vent design, when you slowly open the vent screw, the air inside will come out. I used the Shida brand grease gun, the structure of the vent screw, but can not rule out the gas. I don’t know if they are the parrot or the other finger, or I don’t use its unique function. I made a small modification to it. It is also one of my inventions. Put a hole in the screw or a slot in the saw, so that when you slowly loosen the screw, the gas inside can come out of the slot. Of course, if you don't have such an innate structure, you can also get it through your own transformation.

3, the last one is the ultimate skill invented by myself, and it is often tried and tested. It can make you feel great in front of some small brothers. When you feel that there is gas inside, you can only turn the oil gun body and The pump body is combined with a few times or a few rounds of back and forth (preferably side-by-side pressure) to ensure your success. The reason is not difficult, that is, when you turn, the gas bubbles inside are actually rotating to another part, and the original part is filled with lubricating oil, so the problem is solved.
