Remove Old Grease Cartridge

What happens here

First, locate the plunger rod at the back of the grease gun. Pull this rod completely out until it clicks and locks into place. This action retracts the plunger, creating space inside the barrel for the cartridge to be removed. Once locked, grasp the main barrel of the grease gun and twist it counter-clockwise to unscrew it from the head assembly. Carefully pull the empty grease cartridge out of the barrel and dispose of it.

Goal: Empty the grease gun barrel
