How to Load a Grease Gun

how to load a grease gun

If you want to know how to load a grease gun we have a how-to video that includes directions for how to prime a grease gun that is air-locked and step by step instructions with photos that detail the process.

We just finished some tractor maintenance with our manual lever grease gun so we will be using that type to demonstrate how to refill a grease gun with a cartridge, but most styles of grease gun follow a similar procedure.



Instructions

  1. Loosen the head of the grease gun.
  2. Pull back the plunger and lock it in place.
    • *There could be a notch in the end of the grease gun to set the plunger rod or a metal release tab that you push the rod toward.
  3. Unscrew the head and push the empty cartridge out with the plunger.
    • *You can push the plunger forward to eject the spent cartridge without messing up your manicure.
  4. Remove the cap from the new grease cartridge.
  5. Insert the cartridge in the grease gun, open-side down.
  6. Pull off the metal tab.
  7. Screw the grease gun head back on then loosen it one or two turns.
    • *This will allow any air between the cartridge and the grease gun head to escape.
  8. Release the plunger and slide it into the gun.
  9. Tighten the head of the grease gun and pump until grease comes out.
    • *If you are using a different type of grease than before, pump until you see the new grease.

Priming Air Locked Grease Guns

If nothing is happening then the grease gun is probably air locked. This means that there is still an air pocket between the grease and the head of the grease gun. This is a common issue (We also experienced this at DST headquarters while making our video) but there are two easy solutions.

  • If your grease gun has an air release then you can prime it by unscrewing the release a few turns, pulling the plunger out, and pushing it back in. This should push any air out of the grease gun and allow the grease to flow just fine.
  • If your grease gun does not have an air release then you basically want to repeat steps 7-9; unscrew the head of the grease gun about two turns, prime the gun with the plunger, and tighten the head.

Tips and Tricks

  • Make sure you are using the right type of grease for your application.
  • Best practice is to use the same kind of grease in one grease gun since there will be grease left in the gun from previous use.
  • Clean the grease fitting and the nozzle of the grease gun before use. Pump some grease through the nozzle and wipe it off with a rag.
  • When finished, depressurize the grease gun and store horizontally in a cool place to keep the oil from separating.
  • Cover the nozzle between uses so contaminates won’t enter whatever you grease next.

    I prefer to use a pneumatic grease gun. Is the process of loading grease the same? Do you offer pneumatic or pistol grip (full size) grease guns? I really hate lever grease guns.

      Hey David,

      If the grease gun uses a cartridge then these steps should get you through the process. One convenient difference might be that most pneumatic grease guns have a simpler air release valve, which would make clearing any air pockets easier.

      We are planning on stocking a pistol grip grease gun soon for those who don’t like the lever style.

      Thanks for the question David.
