Puma compressor 5 HP peak 2 HP running

Hey bill, I have a 5hp(peak) 2hp(running) puma cast iron,oil liberated air compressor. It runs for a few seconds and iit shuts off or trips the reset switch. I've drained tank and started over. Same thing, keeps shutting off. Plenty of oil in the sight glass, runs good while it does run, starts up with not struggle turning on. Any ideas? Thank you

If you are powering this air compressor (I added a photo of one that may be like yours) with 120 VAC you are surely not getting anywhere near 5 HP out of the motor.

If you are running this compressor with a 120 Volt extension cord, that may be the problem.

If you are plugged into a 20 amp circuit with little or no other items pulling power at the same time as your air compressor is trying to run, and it still pops the reset, the next thing I would do is check the capacitor. See that page on this site.
