Wangquan YD-50 Air Pressure Oil Filter

When using the machine for the first time, due to the high friction of the sealing rubber ring between the lid, the lid is not easy to close in place. Please apply clean edible oil to the contact between the rubber ring and the lid to improve it. This machine relies on the inside of the barrel as the source of sealing force. When there is pressure in the barrel, the sealing effect is good. Therefore, there is a small amount of air leakage when the pressure in the barrel has not formed during the air pressure process, which is a normal phenomenon. If the air leakage is too large and the air pressure cannot be normal, please clean up the impurities on the rubber ring. If it cannot be solved, replace the sealing rubber ring.
