A grease gun, also known as a grease gun spray gun or a grease pistol, is an inexpensive way to create a quick spray of grease for whatever job you are doing at home or in your garage. There are many different types of guns available to purchase, but the key to creating one that works properly and safely is to follow the directions carefully. This will ensure that you get the most out of your gun and that it will not leak any of your gun lubricant or other material. It is especially important to ensure that you are hooking the grease gun up correctly. Here are some things to do just that:
First, unscrew the piston head from the cover cap. The cap is usually the large part with the lever and applicator tube attached to the grease guns. Unscrew both pieces of this assembly and pull them off of the bearing. Be sure that the cover is closed at the base so that no dirt, dust or debris can enter the area. You need to be very careful when pulling this piece off of the bearing, since it has a lot of moving parts. Make certain that you do it properly by paying close attention to how everything fits and what you’re trying to accomplish.
Next, you need to look at the bearing itself. Look for any signs of over-lubrication or rust. If there is any, then you need to either remove it from the bearing altogether or keep pumping it a bit harder until the problem is fixed. Keep in mind that when you are pumping the grease gun too much, you may cause suction that is too strong and will push the gun towards the wall. This will cause the wall to pull away from the bearing and cause it to break.
Next, check the end cap to see if it is cracked or dented. If it is a dent, insert some more grease into it until it comes out and seals against the barrel. If the end cap was damaged already, then remove it and fix the crack using heat and some silicon oil.
Next, look at the bottom of your cartridge cap. If it is cracked or dented, then remove it and use a putty knife to pry it open. Once you have a good look at it, you’ll be able to determine which side the slot is on. If it is on the bottom, then you can safely unscrew it to get to the greasing mechanism.
Next, you’ll need to look at the end of your barrel to determine which side you’ll insert your new cartridge. Use the same putty knife you used to remove your previous cartridge cap and slide it down the length of your gun. The greasy material should be on one side of the plastic cap, so wipe away with a damp cloth. Once the grease is on the other side of your new cartridge cap, gently turn it counterclockwise until it fits into the opening in your gun’s hopper.
After inserting your new cartridge, ensure that you lubricate both the hopper and the piston rods. Lubrication ensures proper and even filling of your gun’s hopper and piston rod. Next, you’ll need to re-attach the hopper to the end of your cylinder and make sure you follow the instructions for your particular model. It is crucial that you properly secure the cylinder end, because if it slips, then the grease won’t be able to flow out. Make sure you have inserted it all the way into the gun before you close the action and snap the trigger in place.
If you are cleaning out the feed tube, you’ll want to remove the open end of your barrel and make sure you use a rag or paper towel to absorb the dirt and debris that you see splattered on the exterior of your barrel. You can easily clear this mess by using the same rag or paper towel you used to absorb the gun oil. With your new barrel in place, you’ll want to take a look at the insides of your barrel; you should be looking for brass beads or splinters of metal. If you see any signs of corrosion (rust), then you must take the barrel off your gun and replace it with a new one. Then, reassemble your spring, push the plunger rod back through the hopper, and snap the action shut. The process is complete; your gun is now grease and gun cleaning ready!
