Troubleshooting
Grease gun won't prime or dispense grease.
Ensure the cartridge is correctly seated and the follower plate is making contact. Check for air pockets by fully extending the piston and re-pumping. Verify the fill valve is properly sealed if using bulk fill.
Grease leaks from the barrel or head.
Check that the barrel is securely tightened. Inspect the head seal and follower plate for damage or wear and replace if necessary.
Low pressure or volume output.
Confirm you are using the full stroke on the lever handle. Ensure the air bleeder valve (if applicable) is closed. Check for blockages in the delivery tube or coupling.
Coupling won't attach securely to grease fitting.
Ensure the grease fitting on the component is clean and undamaged. Inspect the jaws of the coupling for debris or damage and clean/replace as needed.
