How to Fill a Bulk-Load Grease Gun

When loading a grease gun, there are two options. Pre-filled grease cartridges can be loaded into the barrel, or the barrel can be filled from a bulk grease supply. While cartridges will save some mess, loading from a bulk supply can be cost effective. It is as simple as disassembling the grease gun and adding new grease to the barrel.

Things You'll Need

• Grease gun
• Grease
• Funnel
• Spoon

Instructions

1. Unscrew and remove the head assembly of the grease gun. Pull the spring-loaded rod all the way out until it clicks into the fully extended position.

2. Pour grease into the barrel of the grease gun. It may be helpful to use a funnel, or to scoop the grease in with a spoon.

3. Screw the head assembly loosely back onto the barrel. Release the spring-loaded rod, and push in to eliminate any air from the barrel.

4. Firmly tighten the grease gun head.

5. Open the bleed valve to remove any remaining air from the barrel and hose of the grease gun.

6. Pump the grease gun lever until grease flows evenly from the hose.

Tips & Warnings

• Clean the dispensing nozzle and head before reassembling the grease gun to keep the grease gun working properly.

• Use the bleed valve to release any stored pressure in the gun before removing the head assembly.
