1. Turn the head of the gun away from the barrel
2. Pull the piston up to the top
3. Insert the end of the open barrel of butter into the tube
4. Re-screw the head of the gun and barrel back together
5. Pull up the piston and then quickly lower it. Repeat 2-3 times this is good for pressing the butter.
6. Then crank the gun head handle to use the butter
7. If your gun still can't work, this is because there is still air inside the gun, just turn the gun head bleeder screw to bleed the air.
How to fill the bulk butter
1. Unscrew the gun head
2. Put the gun barrel completely into the butter so that the air will not be sucked into the barrel.
3. Firmly pull the piston tube up to make sure the barrel is filled with butter?
4. Screw the gun head and barrel on, and then pull up and lower it under the live to work.
Major failures
One is the skin bowl is not good, this is almost all the domestic grease gun's common problem, but no wonder, a grease gun structure relative to the ordinary tools, then it is also more complex, sell it for a dozen or so dollars, probably can only be so;
The second is the oil pressure mechanism is not good, but if the spring and the return of the ball is not a problem, probably can not be repaired.
Three is some faults in use, and a lot of faults in use are caused by your own operation, and you can find ways to avoid them. For example, sand, once in the butter mixed into a few sand particles, and at this time you use a pointed nozzle, then ensure that you are angry non-grease gun thrown in order to solve the hate, but also for the equipment is absolutely no good, however, this is actually caused by their own most of the cases. Therefore, we must keep the cleanliness of the grease used, do not use unclean tools to refuel, put the oil container to cover in time
Response
1, if there is a hard pull rod, you can pull the rod several times, so that the air inside can be mixed with the grease and reduce the volume of individual bubbles may be the problem will be solved, but the effect is not every time is very good.
2, the most effective method is the bleed method, but this requires hardware support, some guns have exhaust port design, when you slowly open the exhaust screw when the air inside will come out.
3, the last one is the ultimate skill, and tried and true, repeatedly built the war, when you think there is gas inside and can not hit the time as long as the combination of the oil gun body and the pump body to turn the mouth of the silk a few times or back and forth a few times (preferably the side of the turn side pressure), to ensure that your success. The reason is not difficult, that is, when you turn, in fact, inside the gas bubble is also turning to another part, the original part by the lubricant filling, so the problem is also solved.
