I recently bought a new Yong Heng. I was having trouble with my 5 year old one that I have since fixed. The new one seems to heat up very fast. Ran it for 10-15 minutes under no pressure. I then topped of my Benjamin bottle a couple of times. It was at .5 hours of run time so I changed the oil. I’m using Amsoil synthetic compressor oil. Yesterday I went to top off my 6.8l bottle and had some issues. I only needed to run it about 10 minutes. It heated up fast again. Went up to almost 70 C and right before I went to shut it down my breaker blew. I’m wondering if it just needs some more break in time or if it has an internal problem? When I first got the old one I didn’t own a bottle so it had some hours on it just filling guns.
