How to Load a Grease Gun

Grease guns are used to place long lasting sticky oil onto moving mechanical parts. Parts that may abrade by rubbing against each other need this type of lubrication. Proper lubrication also will increase the service life of mechanical parts. Lubricants are applied with grease guns, which are available at hardware & auto parts stores. Follow these tips to learn how to load a grease gun.

Steps
Load a Cartridge Loading Grease Gun
1 Unscrew the head cap of the grease gun. This is the part of the grease gun with the dispensing head attached. Separate it from the rest of the grease gun, which is the cartridge holding barrel.

2 Pull back on the metal handle on the other end of the cartridge holding barrel. Continue to pull until the plunger rod is withdrawn fully from the barrel.

3 Pull back on the metal handle on the other end of the cartridge holding barrel. Continue to pull until the plunger rod is withdrawn fully from the barrel.

4 Shake the spent grease cartridge out of the barrel. Discard the spent grease cartridge.

5 Obtain a grease gun replacement cartridge suitable for the grease gun. These cartridges are available at hardware and auto parts stores. Typical sizes are 14 oz. (414 ml) and 16 oz. (473 ml) cartridges. Wipe the end of the barrel with a cloth or rag. This will remove excess grease that may have leaked out during removal of the spent grease cartridge.

7 Insert the cartridge into the barrel. Insert the end of the cartridge that had the plastic cap on it first. Push it fully in, so that the end of the cartridge seals with the end of the barrel.

8 Remove the metal seal from the exposed end of the cartridge. Discard the metal seal.

9 Reattach the barrel to the head of the grease gun. Do not reattach it fully at this time. Only give the threads of the 2 parts 2 turns to mate.

10 Release the piston rod from the retracted position. Push it into the barrel while simultaneously pumping the handle of the grease gun.

11 Stop when grease begins to appear at the dispensing head nozzle. Complete screwing together the head and barrel.

12 Push on the piston rod to ensure that it is fully engaged in the replacement grease cartridge. Pump the handle make sure that grease is being delivered.

Load a Reservoir Filling Grease Gun

1 Separate the grease gun head from the barrel of the grease gun. The head is the part with the handle and applicator tube attached. Make sure that the handle on the back of the barrel, which is the handle of the piston rod, is fully depressed into the barrel. Unscrew the two pieces of the grease gun and separate them.

2 Prepare to fill the barrel with grease. Insert the open end of the barrel into a container of grease. These containers are available at hardware stores and auto parts stores.

3 Fill the barrel. Hold the open end of the barrel down into the container of grease and slowly draw back on the plunger rod. This will draw grease into the barrel.

4 Remove the barrel from the grease. When the plunger rod has been fully withdrawn, lift the open end of the barrel out of the container of grease. Rotate the barrel to break it free from grease that may cling to the barrel. Use a cloth or rag to wipe excess grease from the end of the barrel.

5 Reattach the barrel of the grease gun to the head of the grease gun. Engage the threads and turn until the joint is fully seated.

6 Test the dispensing of the grease. Press on the handle of the piston rod and squeeze the trigger of the grease gun until delivery of grease is seen at the end of the grease gun applicator tube.

7 Wipe excess grease from the dispensing tip and the body of the grease gun. Use a cloth or rag to wipe the gun.

Warnings
