Troubleshooting
Grease will not dispense
Ensure the main body is securely tightened to the head. Operate the air bleeder valve to release any trapped air. Check that the cartridge is properly seated or the barrel is fully loaded.
Air leaks from the head
Check the seal between the main body and the head, and ensure the cartridge is correctly installed without damage to its seal.
Stiff operation or reduced grease output
Clean the threads and moving parts. Ensure the grease being used is suitable for the ambient temperature and the equipment. Check for blockages in the extension tube or nozzle.
Difficulty priming
Operate the air bleeder valve while pumping the lever to purge air effectively. Ensure the follower rod is making good contact with the grease.
