Load the Grease Cartridge

What happens here

The task of loading the grease cartridge is delegated to another person. She takes the battery-powered grease gun and attempts to install the new grease cartridge. This typically involves pulling back the plunger rod, unscrewing the barrel, inserting the grease cartridge (after removing the pull-tab or foil seal from one end), reattaching the barrel, and then releasing the plunger rod. During this process, grease inevitably gets on her hands, demonstrating the often messy nature of loading grease cartridges. The initial person then checks if the grease gun is functioning correctly after the cartridge is installed.

Goal: Successfully load the grease cartridge into the gun
