The “How” in Loading and Using an Air Grease Gun
Cartridge Loading
- Separate the gun head and the gun barrel.
- Secure the piston rod by moving it sideways in the barrel so it can no longer move forward.
- Remove Take out the old cartridge.
- Clean the barrel.
- Insert the new lubricant cartridge by pushing it inside. The cartridge’s seal should lay parallel with the barrel end.
- Remove the seal at the barrel’s open end.
- Reattach the gun head to the loaded barrel with a slight unscrewing movement of the parts.
- Position the piston rod back into the barrel.
- Now screw the gun head and barrel securely.
Barrel Reservoir Loading
- Separate the barrel from the head of the gun.
- Place grease inside the reservoir. If you are using bulk loading, place the open end of the gun barrel into the bulk grease container. Now pull up the plunger rod and fill the barrel with grease.
- For bulk loading remove the gun barrel carefully from the bulk grease container. Wipe the gun barrel for residue.
- Once the barrel is full, reattach the gun head to the barrel and close securely.
To use your air pneumatic grease gun, position the gun nozzle to the spot where you need lubricant and press the gun trigger to release the correct amount.
How to Prime an Air Grease Gun
When you purchase your new air grease gun, you will want to prime it before using it to lubricate. A new grease gun will not have any grease on its hose, and you’ll need to eliminate any air pockets inside.
Even without the grease, the piston will still be able to pump the air inside. So, to eliminate this air, you will need to push grease all the way up into the barrel to prime it.
- Begin by unscrewing the barrel container from the housing.
- Now prime the container rim and the grease tube
- Pull out the handle of the plunger completely and secure it in position with the catch plate.
- Insert the cartridge of grease and remove the seal.
- Replace the container tube in the housing and screw it. Loosen the tube by one turn to ease the bleeding.
- Now release the catch plate and push the plunger inward.
- Connect the hose for the air and control the operating pressure. Ideally, the pressure should measure between 30 and 90 PSI.
- Now alternate by pressing the air vent valve and then pulling the gun trigger so you can bleed any excess air within.
- When all the air has been bled and released from the gun, retighten the container tube.
Your air grease gun is now ready for use.
Troubleshooting: My Air Grease Gun Isn’t Working
There are a couple of problems that are pretty common and that can pop up either with a new or used grease gun. Don’t panic if the following happens:
1. The grease gun is not pumping any grease?
- Purge the grease gun of any air pockets. Turn the gun’s base a couple of times in an anti-clockwise direction. Pump the gun while you are rotating its base. When grease appears at the nozzle, close the base. It should be turned clockwise. The other option is to push grease to the end of the container or cartridge manually.
- Check to see if the cap holding the grease in the cartridge has been removed. Also, look for a small metal tab on some cartridges.
2. Your air grease gun is working and then suddenly it stops?
- You may have a blockage somewhere. The air hose may be bad and collapsing under pressure.
