While it might sound like a nuisance to constantly deal with the possibly messy task of loading a grease gun and adding grease to the various fittings of large mechanical equipment, grease is actually the most inexpensive by far, especially when you are considering the total cost of all parts once grease has been added. Whether you need grease for your own personal equipment or you are purchasing a used grease gun or new one, making sure you take care of the task properly can extend the life of your grease gun and make it easier to use. Also, if you do not feel confident enough to do so on your own you might consider hiring someone to do it for you. Regardless, of whether you hire someone to do the job or do it yourself, proper care for your equipment will prevent serious problems from occurring and make the tool longer lasting.
The grease gun is basically a long plastic tube that shoots out a jet of hot grease that will coat both the moving part and the stationary parts inside your equipment. Before starting the process, you will need to prepare the area by covering it in thick painter or floor wax. The reason why you should cover the area is to prevent dust from getting into the gun while it is being used. You can also make the area safer by using masking tape to cover the mouth of the gun and the nozzle end. This is very important because you do not want any accidental leak to occur while the gun is in use and to protect the other equipment as well.
Before you fire the grease gun, you need to pull the plug first. Most grease guns will have two plugs that will have a ball on the end. Push the ball down into the plug and then turn the crankshaft to the clockwise position to begin the rotation. As the rotary crank pulls the plug and ball out, the crankshaft will turn clockwise to drive the ball into the bearing housing.
Now that you have the gun loaded you will need to load another piece of material onto the loading pin. Once you have loaded the second material, you will need to place the loading pin in the housing and load the gun. When you are loading a mini grease gun you will want to be careful so that you do not shoot any material into the face of the housing. Once you have loaded the gun, you will need to apply enough grease to the bearing and then pull the pin out. Apply, more grease to the bearing and continue to load the gun.
After you have loaded the gun you will want to take a look at your connections and make sure that you have all of the appropriate connections connected correctly. You can check to make sure that you have the right amount of connection fittings by looking at the zero mark on the fitting assembly. If the marking is showing the correct zerk, then you will be ready to load your gun and begin work.
After you have loaded the grease gun, you will need to remove it from its housing and place it in its upright position. Place the drain plug into its intended location, and you will want to pull the rod back into the gun. The grease will gather in the crankcase as you are pulling the rod back, and this can prevent your gun from firing if the plug is not properly installed. Make sure that the rod is seated correctly in the barrel and then turn the crank to make sure that the grease is flowing into the crankcase. Push the rod back into the casing and make sure that it is seated in the bore correctly before turning the handle to push it back out of the case.
Many people are intimidated when they start cleaning their grease guns and might find it difficult to perform the basic maintenance tasks. However, with some basic information, you can learn how to keep your grease guns in good shape. First of all, you should know that using an air compressor to power your grease gun can be helpful in making maintenance tasks easier because you can get the air through the housing while you are pulling the trigger. Grease guns are also available with manual grease guns that feature a hammer that you simply touch to apply grease, and these can be handy tools for some applications.
Another important tool that you will want to keep handy when you are using your grease gun is a plastic funnel that has an open end and a sturdy handle, especially if you are going to be using the tool for heavy duty application. This is especially important if you are going to be using the tool for an extended period of time, such as many applications over the course of a day. The plastic funnel can help you pour the grease into the bucket or container and then allow it to stay in place until you are ready to empty it or you press the trigger to release it. If you ever find yourself in this situation, you will want to be prepared by having a plastic funnel in your tool body.
