3hp sanborn magna force slows way down
by Tom Connell
sanborn 3 HP magna force air compressor
I just bought a sanborn 3 hp magna force compressor. It looks to be rather new.
When I turn it on it starts pumping but quickly slows way down and quits running before it gets to 30 lbs of pressure.
I took the belt off the motor and turned it on and the motor runs fine. When I put the belt back on the same thing happens again.
Any ideas on what's going on with this compressor?
