The AL30/40/50/60 are equipped with a check valve on the body.
Therefore, lubricant can be supplied by removing the lubrication plug even when the product is pressurized.
Loosen the lubrication plug slowly, by about 1 turn, to release the pressure inside the bowl.
When pressure in the bowl is released, remove the lubrication plug and supply lubricant.

For AL30-A to AL60-A series lubricators, when the lubrication plug is opened under the pressure of the lubricator, air bubbles may be generated at the end of the oil passage (sometimes they are not). This is also caused by the bowl’s internal pressure being lower than the outlet pressure.
