With this article, I will walk you through the steps on how to load a grease gun and also share with you vital tips that you can work to your advantage along the way.

What You Will Need

Before I discuss the ways on how to load a grease gun, You will need a few essential materials to complete this project. With that said, here are the following particulars you will need.

  • Bulk grease container - you can buy this at any hardware store and be easily used to refill your grease gun.
  • Gloves - you need to wear a pair of gloves during the whole process to keep your hands from touching grease which is difficult to get rid off.
  • Cartridge - they typically come in 14 oz or 16 oz sizes and can be bought at any auto parts shops or hardware stores.
  • Clean rag or cloth - this is to wipe off any grease residue to keep everything clean.

How To Load A Grease Gun: The Step-by-step Procedure

Once you have all the vital materials for this project, you may proceed to go through the simple guide as follows. To do this properly, I will guide you through two ways on how to load a grease gun.

First is with the use of a bulk grease container and the other one is using a cartridge. Now, here are the ways on how to load a grease gun.

1. Bulk Grease Container

1. For this method, begin by detaching the gun head from the barrel. The grease gun head is the part that contains the handle. Carefully unscrew the head which detaches it from the applicator tube.

(Tip: Before doing this step, ensure that the piston rod handle is completely pressed down against the barrel. This will prevent accidental sucking of grease through the gun.)

2. The next step is to fill the reservoir. To do this, open your bulk grease container. With your grease gun barrel opening facing and held down into the bulk grease container, cautiously pull the plunger rod back.

The plunger rod is like a syringe pump attached to the barrel. Pulling the plunger rod back will slowly fill your reservoir.

3. Once you have noticed that the plunger rod is completely drawn already, this means the reservoir is already full. You can promptly remove the barrel from the bulk grease container.

Make sure to wipe off any extra grease from the barrel opening using a clean rag or cloth.

4. Finally, close your grease gun by re-attaching the grease gun head to the barrel. Be sure that you screw the head tightly.

Afterward, you can give your grease gun a quick test by pressing the piston rod and then give the trigger a squeeze.

2. Cartridge

1. For this method, start by removing the old cartridge. To do this, unscrew the grease gun head and detach it from the barrel. Gently remove the old cartridge from the barrel.

(Tip: Before doing this, make sure that the plunger rod is completely withdrawn and locked to prevent it from springing back.)

2. Next is to prepare the new cartridge. Remove the cap of the new cartridge by unscrewing it.

Once you have unscrewed the cap of the new cartridge, you can insert it into the barrel. Remember to insert the open end first of the new cartridge inside the barrel.

3. Once the new cartridge is fully inserted into the barrel, you will notice that it has a metal seal. Remove the metal seal carefully.

4. Re-attach the grease gun head to the barrel. Nevertheless, do not fully screw the grease gun head on just yet. Release the plunger rod and nudge it in slowly to get rid of any air pockets.

Afterward, screw the head fully and tightly. Give your grease gun a few pumps to check if it is adequately functioning.

Main Types Of Grease Gun

There are four primary types of grease guns that offer a variety of features. And like any other tool, they also come with their own set of guidelines of how to use as well as for their proper maintenance.

1. Manual 

This type of grease gun typically features a pistol-grip or a lever-action. The manual grease gun is the type widely used and is considered the most low-cost. They can achieve up to 10,000 pounds of pressure per square inch.

2. Battery-operated 

Another type of grease gun is the battery-operated. If you require speed in terms of your lubricating jobs, the battery-operated grease gun is the most efficient tool to use.

They can go up to 6,000 to 10,000 pounds of pressure per square inch depending on the specific model.

3. Air-powered 

The next type of grease gun is the air-powered or sometimes referred to as pneumatic grease gun.

This operates using compressed air that exerts pressure to the piston that pushes the lubricant unto the fitting of the grease gun.

The lubricant will then flow freely once the trigger is squeezed. Air-powered grease gun can reach 6,000 pounds of pressure per square inch.

4. AC Electric 

Considered as an effective alternative to an air-powered grease gun is the AC electric grease gun. They are also referred to as corded grease guns.

This type of grease gun provides a constant and fluid flow of grease and can easily reach up to 7,000 pounds of pressure per square inch.
