Grease guns are common tools that are designed to efficiently apply grease to a specific point of application. Sears (via Craftsman) makes a wide variety of these devices, and aside from learning how to correctly apply grease with them, a user must also know how to refill them with replacement grease cartridges from time to time. Regardless of what model grease gun you have, there are two ways to refill a multi-load cartridge grease gun, both of which are easy to accomplish if done correctly.

- Moderately Easy
Things you need
- Replacement multi-load grease cartridge (or)
- Bulk grease in a tub
- Clean rags
Place the grease gun on a flat work surface that will not be damaged by contact with grease. Wipe down the tool with a clean rag to remove surface dirt and excess grease. Loosen the grease barrel from the bottom of the tool by turning it counterclockwise. This is the component that stores grease until it is applied by the grease gun during operation; it is usually hanging below the grease gun when in the operating position.
Place a clean rag beneath the grease gun, then unscrew the barrel completely to remove it from the tool. Do not allow any dirt or foreign debris to enter the exposed portion of the tool.
Remove the empty multi-load grease cartridge from the barrel by pulling the cardboard sides of the cartridge straight out from the top of the open barrel. Set the old cartridge aside for disposal.
Grasp the barrel firmly with one hand, then pull the T-handle (located at the base of the barrel) back as far as it will go. The T-handle is spring loaded, so a bit of strength may be needed. Allow the T-handle to "catch" in its recess, indicating the handle is at the full "back" position. This manoeuvre moves the plunger located inside the barrel out of the way to allow for grease replacement..
Peel open one end of a new replacement multi-load grease cartridge, then slide the open end of the cartridge into the barrel of the grease gun. Remove the aluminium foil ring pull from the now visible end of the cartridge.
Manually refill the empty grease cartridge with fresh grease from a grease tub or tube if no replacement multi-load cartridges are available. A kitchen spatula is a convenient way to transfer the grease. Avoid leaving any air pockets in the cartridge as you refill it.
Screw the barrel back onto the grease gun using a clockwise motion until it is firmly in place. Depress the plunger (T-handle) release located on the bottom of the barrel to release the plunger and T-handle to the operating position. Squeeze the grease gun trigger a few times to prime the gun, which is now ready to use.
Tips and warnings
- An alternative to refilling an empty cartridge with a kitchen spatula from a tub of grease is to insert the open end of the barrel into the grease tub, then slowly withdraw the T-handle. As the level of grease in the tub transfers into the barrel, keep the lip of the barrel below the surface of the grease.
