A grease gun is a mechanical tool used to lubricate machines. The grease gun is suitable when applying a lubricant via an aperture to a particular point. It is also used in applying oils or grease to machinery, tools or car parts through a nipple.
Investing in a grease gun is great because you will be able to apply lubricants to various parts of your tools. Doing so helps your devices to last longer and be in good condition in times of need. Moreover, you need to know how to use a grease gun or else your tool may depreciate rather than give you the proper service.
Types of Grease Gun
There are various types of grease guns in the market today. Different types vary in the way they are used for example, how to load grease. Below are the kinds of grease guns.
a) Hand-Powered Gun
A hand-powered gun applies the spring mechanism. By cranking the gun, pressure builds up and pushes the grease out through the nozzle. Another type of grease gun is that one with only a piston when pressed oil comes out. The second type is unique because it does not use the trigger mechanism.
b) Pneumatic Gun
The pneumatic grease gun is air-powered. These guns’ forces grease out through the nozzle while using compressed air that is dispensed by hoses.
c) Battery-Powered Guns
The battery-powered gun suits higher volumes or high-pressure lubrication. They use batteries as their source of energy.
How to Use a Grease Gun
i) Load the grease gun
You have to load the grease gun before its use correctly. This step is the most vital one because it determines whether grease will come out or not. You can do so by following the procedure below;
- Eject the head of the barrel.
- Backtrack the rod handle and lock it.
- Open the grease cartridge.
- Inject the cartridge into the barrel.
You should remain vigilant of the pull-tag located at the cartridge end. Ensure that you push the cartridge until its rim and the grease gun’s rim are in close contact.
- Reinsert the barrel to the cap end but leave it loose.
- Discharge the rod handle and enervate it so that the grease flows into the head of the grease gun as it forces air out.
- Check if oil will come out of the nozzle by pumping the grease gun.
- Finally, connect the grease gun.
A grease gun is also loaded through suction from a tube consisting of grease. The procedure for this method is below.
a. Eject the head from the barrel.
b. Pour excess oil into the head.
c. Put the gun barrel over the grease tube.
d. Inject the barrel for about 5 centimeters into the lubricant.
e. As you remove the rod handle, apply little force on the barrel to depress it.
f. Clamp the plunger when it extends to the fullest.
g. After filling up the gun barrel, move it aside to halt the flow of extra grease.
h. Clean the parts of the grease gun using a paper towel, stiff paper or rag.
i. Connect the barrel to the grease gun.
j. Finally, release the handle and put some pressure on it, and grease will commence running.
ii) Choose Your Target Location
After loading a grease gun correctly, you should identify the specific tool and location where you want to lubricate. Rotating parts often require lubrication.
iii) Applying the Grease
Foremost check if the gun is working in good condition by ensuring that grease flows out via the nozzle. After securing it is in excellent condition, you can then connect the nipple of the gun to the part you intend to lubricate.
You should have the right quantity of grease enough to lubricate your tools. Afterward, you have to build up enough pressure that can push the oil out. Pull the trigger and direct the nipple to the location you intend to lubricate. Alternatively, you can use a piston to build up pressure before releasing the grease to the parts you are lubricating.
Below is a procedure for applying grease using a hand-powered grease gun.
- Begin with clamping the nozzle into place.
- Using the hand-crank, create enough pressure and pull the trigger to lubricate your instrument.
- Before releasing the tension, ensure that you have directed the nozzle towards the place you want to grease.
Maintenance of Grease Gun
For a grease gun to function correctly, you should ensure that the nipple remains clean on a regular basis. Additionally clean thoroughly and wipe to dry your grease gun before storage. Following are some of the maintenance techniques that ensure proper functioning of the grease gun. It is advisable to learn and put them into practice.
Consider the tips below:
i. You should avoid mixing old grease and new grease.
ii. Ensure that you use separate guns for various lubricants.
iii. Avoid using excessive force when tightening your gun head, and too much pressure can cause failure.
iv. Pumping out excessive grease from a coupler thus expanding its life.
v. To avoid greasing your attire, consider changing into work clothes or wear an apron before using a grease gun.
vi. Avoid putting too much pressure when lubricating since excessive force can destroy bearing seals or shields.
vii. Clean up the spilled grease immediately after use, and a grease spill can easily cause one to fall.
viii. You should not operate your grease gun near a fire.
ix. You should rinse the nozzle using warm water and dry your grease gun before storage.
To sum it up, a grease gun is an essential mechanical tool because of its use in lubrication of instruments. Lubricating the moving parts of a machine is vital because it increases the functionality of the device as well as expanding its’ lifetime.
The content above provides guidelines on how to properly use a grease gun as well as the maintenance measures one needs to follow.
It is important to note that there are various types of lubricants. These oils and lubricants are found in local spare shops. To achieve maximum effectiveness one should consider buying heavy and thick grease.
