Features to Look For
Now that you’ve read the list of top ten grease guns, here are some features to consider:
Grease Delivery Mechanism
Grease guns deliver lubricant through a variety of mechanisms. There are air or pneumatic grease guns. These use the power of an air compressor to push out the lubricant. There are also electrical guns. These rely on electricity that is usually powered with a battery pack or cartridge. Finally there are manual guns. Here the lub is forced through with a trigger or plunger action.
Grease guns protect other items from wear and tear. It’s important to protect them as well. A gun that comes with a carrying case is likely to last longer as it won’t be exposed to shop grime and other elements.
Pounds Per Square Inch (PSI)
This is the amount of pressure with which the lubricant is forced out of the grease gun. Some jobs require a higher PSI others need a low PSI, often to avoid breaking seals. Before making a purchase, it’s important to know which PSI range is right for you.
A debris filter traps any dirt or sediment that could otherwise travel through your grease gun. This debris can damage your gun. It can even get into the parts you are trying to lube. The filter traps this for you to protect your investment.
Cord or Cordless
Depending on the grease gun you select, yours may or may not have a cord attached. The corded units normally attach to an air compressor. These corded units have quite a bit of power, but there’s also some inconvenience involved. You’ll have to store and manage your hoses, and they can be a bit of a tripping hazard.
Frequently Asked Questions
Question: How do you load a grease gun?
Answer: This depends on the type of grease gun. Here are some of the methods used:
- Loading a Reservoir Grease Gun: First, unscrew the head from the barrel. As you do this, keep the handle depressed. Once this is done, dip the open end into the container of grease. Pull the plunger rod back and allow the suction to fill the reservoir. Once finished, pull the barrel out of the grease container. Turn the barrel and wipe off any excess grease. Finally, reattach the head. The exact mechanism used to attach and detach the head can vary from gun to gun. One of the best things to do with these guns is to have a large container of grease on hand for loading and unloading.
- Loading a Cartridge Grease Guns: These units are a bit cleaner to load and reload. That’s because all of the grease is inside of the cartridge. When you need more grease, you simply purchase another cartridge. Reloading usually involves unscrewing the cap, twisting the cartridge one way, and turning the dispenser the other way. Move the piston rod over, and you should be able to remove the cartridge. Again, the exact method depends on your grease gun, and the instructions that are provided with it. Next, you can add a new cartridge. It’s easy to find them at hardware stores or auto parts stores. Take the cartridge and push it firmly into place. Finally reattach the head to the barrel.
Question: What kind of lubricant should I use?
Answer: You always want to choose a high quality lubricant. You don’t want a cheap lube that will clog the gun and cause buildup. In addition to this, if you use multiple lubricants, have a separate grease gun for each of these. The reason for this is cross contamination. Different machinery and equipment requires different lubrication for a reason. For example, one lubricant may be suitable for high temperatures while another is not. You don’t want to compromise that by using a lubricant that has been contaminated with an unsuitable one. If you must use one gun with multiple lubricants, purge and clean your gun after each use.
As long as you choose a quality lubricant, brand really doesn’t matter. What does matter is that you keep your gun in good repair, and you calibrate it annually. To do this, simply pump your grease gun ten times while allowing the grease to fall onto a scale. Weigh the grease. Divide that weight by ten. Now you know the approximate volume of grease that is expelled with one pump. Keep a record of this. It’s important, because certain pieces of equipment require a very exact amount of lubricant. Technicians need to know how many ‘pumps’ to use.
Question: How can you tell if you’ve too much or too little grease?
Answer: It’s important to use the right amount of grease. While some machinery has a fairly liberal tolerance, others need a very specific amount. Both over or under-greasing can cause damage, if not immediately then over time.
You know that you are overgreasing if there are jams, damage to seals, and issues with motor windings. To prevent this, make sure anything you are lubricating is clean, and that any debris or crust has been removed. As you apply the lubricant, pull back if you feel pressure. You can also use a grease gun with a pressure gauge. Sometimes, gradually pumping grease in is better than continuously feeding it through. The pumping gives time for the lubricant to distribute properly.
Unfortunately, if you under-grease something it will often break down. That makes the issue easy to detect. Fortunately, if you are observant, you may be able to catch the issue before something catastrophic happens. Look for overheating, burning or friction smells, unusual wear and tear. In the event that something has been running without proper lubrication, have a mechanic look at it. Don’t simply pump in more lubricant.
Question: What does a coupler do?
Answer: A coupler is a pipe that lets the user attach the gun to a mechanical component. It is used to lubricate moving parts.
