1. Turn off the oil gun head to separate the oil gun head from the barrel.
2. Immerse the opening part of the barrel into the barreled butter about 30 mm deep, hold the barrel in one hand and pull the driven handle at the end of the barrel backwards to inhale the butter into the barrel. 3. Install the oil gun head, press the locking plate at the end of the barrel and push the driven handle into the barrel.

Butter guns include hand butter guns, pneumatic butter guns and pedal butter guns. Now more and more buyers like the hand butter gun. Such machines as excavators, cranes, large construction machinery and so on, can improve their work more efficiently with manual high-pressure butter guns. This product has large capacity, high pressure resistance and wide application.
Notes: Air is easily left in the barrel of this oil loading method, which leads to no butter. At this time, the driven handle at the end of barrel should be pulled to the bottom, then the locking plate at the end of barrel should be pressed with one hand, and the driven handle should be pushed into barrel to discharge the air in the barrel. This method is called exhaust method for short. Another exhaust method is that when there is no exhaust valve on the butter gun, the driven handle can be pushed several times in the barrel, then the exhaust of the gun head can be loosened slightly and the gun head can be tightened.
