If you've actually spent a whole evening pumping a manual lever, you know specifically why an air operated grease gun is the total game-changer with regard to anyone maintaining machinery. Let's be true: manual greasing will be a literal pain in the hand. Whether you're functioning on a tractor, a fleet associated with trucks, or simply several heavy equipment in the garage, the moment you hook up to a compressor, your life gets about ten times easier.
The advantage of heading pneumatic is that the air does all of the heavy lifting. You're not really fighting against a stubborn fitting or trying to sense of balance a heavy tool while awkwardly squeezing a handle. Instead, you simply pull the trigger and allow the grease circulation. But, like any tool, there's the bit of the learning curve to picking the right one and keeping it running without making a massive mess.
The reason why In order to Pneumatic Grease Guns?
The most obvious reason is speed. If you have fifty grease points on an item of heavy tools, doing that by hand is heading to take permanently. With an air operated grease gun , you can move from one fitting in order to the next in seconds. It's not just about being "lazy"—it's about efficiency. When a job takes less time, you're more most likely to actually do this, which means your bearings stay lubricated and your tools lasts longer.
An additional thing people forget is consistency. When you're pumping simply by hand, the pressure varies with each stroke. A pneumatic setup provides a steady, high-pressure stream that can blast through dried-up crust or old, hardened grease that a regular gun might struggle to penetrate. Most associated with these units can put out any where from 3, 000 in order to 6, 000 POUND-FORCE PER SQUARE INCH, which is more than enough to clear out a persistent zerk.
Constant Flow vs. Individual Shot
This is the first big choice you have in order to make. Not almost all air grease weapons work the exact same way. You'll usually see two main types: continuous stream and single chance.
Constant flow guns are fundamentally the "machine guns" of the grease world. As long as you hold the trigger down, the grease retains coming. These are amazing for large bearings or pivot factors that need the lot of volume. However, you have to be cautious not to over-grease, which can actually strike out seals if you aren't paying attention.
Individual shot guns, on the particular other hand, provide one "burst" associated with grease every period you pull the particular trigger. If a person need more, a person let go plus pull again. These provide you with way even more control. In case a manual says "three penis pumps, " you pull the trigger 3 times and you're done. It's very much harder to unintentionally overfill a keeping with one associated with these.
Features That Actually Issue
When you're shopping around, it's simple to get distracted by shiny chromium or high price tags, but there are only a several things that really matter in the long run.
The Hose Duration and Flexibility
Don't settle for a short, stiff hose pipe. You're going in order to be reaching directly into tight spots, below chassis, and at the rear of engine blocks. A 12-inch or 18-inch flexible whip hose is almost mandatory. If the gun comes with a firm pipe, you'll most likely end up buying a flexible extension anyway, so you might as well get one particular which has it from the start.
The Coupler Quality
There is definitely nothing more annoying than a coupler that won't remain on the fitting or, worse, one that gets stuck and won't come away. Look for a high-quality 4-jaw coupler. Many people even improve to people "lock-on" design couplers that you can clip on to the zerk which means you don't have to hold it in place. It makes the whole process hands free, which is a massive win.
Air Pressure Requirements
Most air operated grease gun models run on standard store air, usually among 40 and 150 PSI. You don't need a massive industrial compressor to run one particular, however you do need to make sure your regulator is placed correctly. If you feed it too much pressure, you might blow a seal inside the particular gun itself.
Dealing with the Famous Air Lock
If you've used a grease gun before, you understand the "air lock" is the greatest enemy. You place inside a fresh container, hook up the air, pull the cause, and nothing. Just the sound of air hissing plus no grease coming out.
This happens because a wallet of air will get trapped between the particular plunger as well as the grease. Most pneumatic weapons have a bleeder valve (usually a little button or the screw near the particular head). You just provide that a push while the gun is under pressure to let the air out. If that will doesn't work, you might need in order to unscrew the clip or barrel a turn or even two to let the air escape, then tighten it back up. It's a bit messy, but it's part of the sport.
Keeping Things Clean (Or as Clean as Possible)
Grease is inherently messy. There's no getting around it. But a good air operated grease gun can actually be solution than a guide one because you aren't wobbling the particular tool around while looking to pump.
One professional tip: always clean from the zerk fitting prior to you put the coupler on. If you don't, you're just treating dirt and resolution directly into your bearings, which defeats the whole objective of greasing all of them. Also, keep a rag handy in order to wipe the tip of the gun when you're done. Grease has a way of migrating onto every surface associated with your shop if you aren't careful.
Is it Worth the Investment?
If you're only greasing a lawnmower once a year, honestly, stick with a cheap hand pump. But if a person have more than two or three pieces of equipment, or in case you're doing upkeep once a month, an air operated grease gun is worth every penny.
They aren't actually that expensive any longer. You can get a solid, reliable unit for an affordable price. When a person element in the stored time and the fact that your hands won't feel like cramped claws with the end associated with the day, the tool basically will pay for itself.
A couple of Final Tips intended for Longevity
In order to make sure your tool lasts, don't leave it connected to the air line when a person aren't utilizing it. Constant pressure for the internal seals can use them out too early. Also, try in order to stay consistent along with the type of grease you use. Mixing different types of grease (like lithium and polyurea) can sometimes result in them to break down or solidify, which can clog up your gun.
At the end of the day, an air operated grease gun is one of those tools that will makes you wonder why you continued to wait so long in order to buy one. It turns a tiresome, dirty chore straight into a quick job that you may knock out in minutes. Just keep it clean, hemorrhage the air away when you change cartridges, and it'll likely be the last grease gun you ever have to buy.
