How to Use, Features, Maintenance & Refilling of Grease Gun

Greasing guns are tools you need when lubricating mechanical parts, particularly those difficult to reach. Their applications are immeasurable in auto maintenance, industrial environments, factory applications, and agriculture. Regardless of the greasing reasons, let’s learn more about how these tools work and use them.

You will need a lubrication tool for home mechanics and general mechanical maintenance. Learn more about features, maintaining, refilling, and eventually using guns for greasiness. Areas that are subject to friction require frequent lubrication for optimal performance.


The ergonomic design makes the gun easy to operate with a single hand. The locking coupler enhances flexibility. The maximum working pressure facilitates the sealing and casting of the head. The handle also has a rubber sleeve for safety.

Operating is relatively simple if air pockets get filled. An air bleed valve helps you release all air with a single push of a button to avoid axial bending. Removing the gun from clogged fittings with a steel barrel is easy. It has a bit of lubricating oil for long-term use to prevent rust.

How to use

Remove the head from its barrel before injecting a lubricant. Retract the rod handle and lock it. Open the new grease cartridge; it is usually 56 mm in diameter and 300 mm in length, and insert it into the barrel. Ensure the cartridges and barrel’s rims are in contact while noting the tag end of the new cartridge. Return the barrel to the cap of the grease gun while keeping it loose.

Turn the rod handle out of the groove to release and depress it to force the air out. Use the handle until the grease begins flowing. Try it out by pumping the lubricant through the nozzle and cleaning it before returning it to the nozzle. Push down the air bleeder while tightening the cap to eject all the air and place the coupler on the hose.


Maintaining the vertical position of a grease gun while capped at all times during storage is a good practice. It prevents leaking and helps you use it without making unnecessary replacements. Depressurize the gun whenever you leave the cartridge in the gun. Also, avoid exposing the gun to heat for long periods, as it can cause the grease to separate.


Don’t let the gun go empty. Refill it whenever grease drops below the working level. Place the open end of the gun’s barrel into a grease container. Begin refiling by holding it down into the container and gently pulling back the plunger until the barrel is full. Use the centrifuge method to handle grease separation when it occurs during refiling.


To wrap it up, greasing equipment has different sizes and brands, but knowing how to use them is suitable for safety and is also part of the maintenance. Always keep the gun greased, refill it whenever it nearly runs dry, and use its features.

As a result, the information above will act as reference when planning to purchase this device.
