The grease gun supports four loading methods: 1) Cartridge Loading (paper or plastic), 2) Bulk Loading (scooping grease), 3) Suction Loading (pulling the plunger to draw grease in), and 4) Filler Pump Loading (using the bulk loader valve).
If the gun pumps little or no grease, it is likely due to trapped air pockets. To prime the gun, loosen the head 2-3 turns, disconnect the plunger rod, and force the rod in and out to expel air. Once grease appears at the loose thread connection, retighten the head.
Grease leaking around the plunger rod typically indicates a damaged rubber follower inside the barrel. This component usually needs to be replaced to restore a proper seal.
