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, reduce the volume of individual bubbles may be the problem will be solved, but the effect is not every time 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 feel that 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 filament a few times or back and forth a few times (preferably the best side of the turn side pressure), to ensure that you succeed. The reason is not difficult, that is, when you turn, in fact, the inside of the gas bubble is also turning to another part of the original part by the lubricant filling, so the problem is solved.

4, pull the lever out, so that the cylinder piston near the rear cover, and then lock the lever.

5, to the barrel of the lubricating grease. When using the grease filler, the top thread of the cylinder, on the thin screw in the grease filler, the grease filler to lubricating grease into the cylinder. If you use your hand to load lubricating grease directly into the barrel, first screw down the front cover, use your hand to load clean lubricating grease directly into the barrel until it fills up the whole barrel, then screw on the front end cover, unlock the lever, and use cotton gauze to wipe the grease gun.

6, one hand holding the cylinder, the other hand holding the hand lever, press the hand lever back and forth to discharge the air in the cylinder, when found at the mouth of the lubricating grease, stop press the hand lever.

7, will be injecting oil rod front end of the injection nozzle aligned and tightly pressed in the need to lubricate the grease injection parts of the grease nozzle, will be close to the hand pressure lever down near the barrel, until it can not be pressed until, and then lift the hand lever to the original position, and then press down on the uplift, snap the hand lever back and forth to the lubricant can be slowly pressed to lubricate parts of the people need to be lubricated, after the filling of lubricating oil and grease, pull out the grease gun.

8, if the grease gun grease rod front inconvenience close to the lubrication of the injection parts, should be in the grease rod on the sleeve of a section of the hose, and the set of buttons firmly, in order to prevent extrusion injection of lubricating grease from the mouth of the set of leakage, at the same time, in the hose at the other end of the mouth of the mouth of the installation of a grease nozzle threads to match the mouth of the sleeve and the internal plug, will be the internal plug into the injection of oil injection part of the grease nozzle, and then tighten the mouth of the sleeve, according to the method described above can be added to the injection of grease to the grease. The grease can be injected into the grease injection area as described above.
