A Detail Guide: How To Use A Grease Gun

Any auto repairman, an engineer or a handyman who doesn't have a grease gun wants to take the hard road. Lubricating machinery can be labor-intensive because you will need to exert effort to achieve your aim. The good news is that if you have a grease gun in your toolbox, you can handle those jobs easily and very fast.

A grease gun is used to apply grease or oil to car parts, machinery, tools, etc. through the grease nipple. It is a simple device that you can use easily if you know how you can dismantle it and know all the parts it has.

Acquiring a grease gun is very important because it helps you to lubricate parts so that they can last longer and always work properly when you need them. Although the device is easy to use, you must know how to use it or else, the parts may depreciate instead of serving properly.

Types Of Grease Gun

To use a grease gun, you must first know the available types there is in the industry today. Don't forget that each type may have different usage styles like the difference in the way you load the grease. So how many are there today?

Hand-powered gun

Hand-cranking builds the pressure for this type of grease gun, and the trigger which is a spring mechanism is used to apply pressure which will push the lubricant out from the opening. There is also another type that doesn't make use of a trigger mechanism. It only has a piston in the body that when you apply pressure to it, the grease will come out.

Pneumatic Gun

This type of grease gun is air-powered. The hose uses compressed air to force grease out from the outlet.

Battery-powered guns

This type of grease guns is suitable for high volume and high-pressure lubrication.

Another important thing I want you to note on how to use a grease gun is the types of lubricants available. Many commercial oils and lubricants are readily available in the market today. Do you want to get the best out of the operation, ensure that you use the heavier or thicker grease. You can get some as a refill cartridge which you load directly, or you can get the type that you will fill manually.

Now that you have known the basics let's see how you will use the grease gun properly.

How TO Use A Grease Gun

Load the grease gun:

The first thing is you have to load the grease gun carefully before using your grease gun. To achieve that, do the following:

  1. Remove the head from the barrel
  2. Pull back the rod handle
  3. Lock the rod handle
  4. Open your grease cartridge
  5. Insert the grease cartridge into the gun barrel
  6. Be mindful of the pull-tag which you will see on the cartridge end
  7. Make sure that you have pushed the cartridge to the extent that its rim will be in close contact with the rim of your grease gun
  8. Reinstall the gun barrel to the cap end but make sure that it is loose.
  9. Release the rod handle
  10. Depress it so that grease will flow into the head of your grease gun while forcing air out
  11. Pump a little grease through the nozzle and clean it
  12. Attach it to the grease gun.

Anatomy of Grease Gun

Apart from the above method, you can load the grease gun through suction from a tube containing grease. If you prefer this option, do the following:

  1. Remove the head from the barrel
  2. Introduce a large quantity of grease in the head
  3. Place the gun barrel over the tube of grease
  4. Insert the gun barrel about 5.1 cm into the grease
  5. As you pull up the rod handle, apply pressure on the barrel to push it down
  6. Lock the plunger when it extended to the fullest
  7. When the barrel is filled up, move the barrel sideways to cut off any extra grease.
  8. Clean the whole parts using a rag, stiff paper or a paper towel.
  9. Attach the barrel of the grease gun to the main device
  10. Unlock the handle
  11. Pump the handle, and the grease will start flowing.

Choose the target location on the part

After you have loaded the grease gun correctly, the next thing is to identify the exact location where you want to lubricate on the part. Your first target, of course, should be the rotary part of your machinery.

Applying the grease

The first thing you have to do is to check if the gun is working properly by ensuring that the grease will flow smoothly. When you are certain, connect the nipple of the grease gun to the part where you want to lubricate.

The next thing is to determine the quantity of grease that will be enough for the part. Then, build the pressure that will force the grease out through gun's hand crank.

When you are sure that the pressure is enough, pull the trigger. Don't forget to direct the lubricant directly on the location through the gun nipple. You can also pour your lubricant by creating adequate pressure through the piston which is located at the end of the gun barrel.

One thing to remember here is that if you use a pneumatic grease, you will achieve the result more effectively.

Maintaining the grease gun

Every important tool we have needs adequate maintenance to function properly. The grease gun is not an exception because for it to function as smoothly as you require, you must take care of it.

Important tips to remember

  1. Don't mix old grease and new grease together
  2. Use suitable grease gun for the type of lubricant you have
  3. Avoid pressure failure by tightening the gun head appropriately but not too tight
  4. Always wear glass and gloves before using a grease gun
  5. Avoid accidental falls by cleaning spilled grease
  6. Keep fire away from the grease gun while in operation.


As long as you are using one machinery or another, you need to lubricate them from time to time. Not only to ensure that they work very well but also to extend their useful life.

One great tool that you should have is a grease gun because it can make things very easy and fast. It may have seemed difficult before, but after this article, I am sure that you can now use your grease gun without stress.
