How to Load and Use a Grease Gun

If you own a tractor, zero-turn lawn mower, utility trailer, boat trailer, motorcycle, or heavier nibble of equipment like a stevedore, excavator, or dump truck/trailer you have fittings that need to be greased so they operate properly, but possibly most importantly, do not fail during use and save you from dearly-won repairs and consume time .

Learn Where the Fittings Are

If you ’ rhenium operate equipment commercially ( even if that ’ mho merely a weekend lawn path ), it is in your best pastime to learn where all the fittings are on your machine ( second ) and to make sure they ’ re properly lubed. It ’ south minutes and pennies pro-action immediately versus a dollars, days, and downtime chemical reaction late .
once you locate all the fittings ( called Zerk or Amelite ) you ’ ll need to know how to load a dirt gun then operate it safely and effectively. Compared to, say, remodeling a bathroom, this is an easy skill to acquire. But like any maintenance bodily process, it should be done with care .

Get to Know You Grease Gun

intend of a dirt artillery like a mash-up of a hard-hitting caulk gun and a cordless drill. Grease is like caulk ; actually sticky, gooey, not-easy-to-clean caulk with packaging that can lay you capable.

On the tool itself, there is a diver, the tool body ( or barrel ), the actuator assembly ( head ), and a fixed nozzle or flexible hose at the end of which is a coupling that seats on the Zerk. Some crank candid and closed like a cordless drill ’ s 3-jawed chuck catches a exercise act shank. Others are simply held on by hand-pressure. Which one works best for you is a topic of test and erroneousness and preference .

Types of Grease Guns

There are lever-actuated dirt guns, pistol-grip actuated grease guns and cordless battery-actuated dirt guns .
For around-the-house manipulation, pistol-grips are advisable at a mid-range price. You can hold the hosiery or nozzle with one pass and pump with the other. But in all cases, we ’ rhenium talking about some pressure. Cordless dirt guns are pushing at up to 10,000-psi .
Out of the box, the grease gun may have a flexible hose or a fixed metallic element tube. Both have their advantages and disadvantages in particular applications, and most mechanics and heavy equipment operators end up with at least one of each .

Selecting Grease

The grease selected matters a bunch, a badly option can get expensive .

  • All grease is not of equal quality. Only use premium grease, it is the cheapest part in the machine no matter how much it costs per tube.
  • Use the right grease for the job. In modern equipment, specialty lubricants are sometimes specified. Check with the manufacturer of the equipment you’re using to get the correct recommendation.
  • DO NOT MIX GREASE TYPES unless you know what you are doing. Chemical incompatibility in lubricants can destroy bearings very quickly. Read more about determining grease compatibility, as well as this resource, to understand the concept in greater detail.

How to Load a Grease Gun

Most grease guns operate on the lapp principle mechanisms. Be certain to read and understand all the manufacturer ’ s directions before habit.

  • Pull the plunger back (there is a spring inside being compressed when you do this—this is important to know later; more on it below) and rest it on the catch in the tool body.
  • Unscrew body from the head.
  • If the gun has an old grease tube in it, remove the tube. If the tube is jammed carefully and slowly release the plunger to push the tube out. Re-latch the plunger once you can get a grip on the tube.
  • Check that the gasket that seals the tool body to the actuator head hasn’t gotten buried in grease and thrown away with the old tube.
  • On the new tube, remove the plastic cap and insert the tube into the tool—open end toward the plunger.
  • Remove the pop-top or foil. This lid is astonishingly sharp, be mindful.
  • Re-assemble the tool.
  • For tools with no bleeder valve, the unit must be primed, or burped, to get any air out. Thread the unit back together and back it off one turn. Release the plunger. You may actually have to push it down through the grease. Tighten the tool and dispense grease onto a piece of cardboard until it flows burp-free. If the handle doesn’t resist the pressure you put on it, there is air in the tool. Keep pumping until the flow is uninterrupted.
  • For units with bleeder valves, the air can be evacuated through the valve.

How to Use a Grease Gun

Always clean off the Zerk fit with a tease before putting the grease gun coupling on it or you are pumping contamination into the bear assembly .
A Zerk is a combination ball valve and check valve. The dirt gun depresses the musket ball ( bantam ball bearing ) allowing grease to fall. When you remove the tool a leap pushes the ball spinal column into the hatchway, sealing it. If the behave doesn ’ thyroxine return and dirt leaks out, there may be particulate matter obstructing its proper operation and you should get a new Zerk .
Under normal practice, pump in enough grease that you hear escaping pressure and see good a little snatch of grease drift extort out of the fabrication. basically, you ’ re replacing the old grease with newfangled grease .
Don ’ deoxythymidine monophosphate precisely keep pumping in dirt, however. You may besides check with your equipment trader ’ sulfur service department about tips for how best to grease the fittings. Wipe off any excess dirt .
If the wheels are submerged in water ( like gravy boat trailers ) it ’ s better to install a hub greasing system like Bearing Buddy, which makes sustenance easier .
Any time you are greasing something that has a apprehension point or can fall ( particularly dump trucks and booms on equipment ), either have them in the lower position or propped up with an approve tittup to avoid injury .

Continued Use

even the best grease accelerator will finally leak at the plunger. If you try to pull back on the speculator and it doesn ’ t move easily, stop. This probably means that grease is behind the plunger seal, and if you persist, that dirt will come out the back of the gunman all over you and the shop floor.

Go over to the pan can, get some fairly rags handy, unscrew the cap over the methamphetamine can, and set the cap aside. Pull the speculator second over the folderol can so the grease behind the plunger goes there .
now you can reload as mentioned above .
