Testimonial: "Thank-you so vey much much. "
Mike, an EP 75 Should not use more than 3 to 5 parts per million of oil. Your oil issue sounds like you have a separator that needs replacing or a plugged scavenge line. The separator is located in the oil tank. the scavenge line and orifice come from the bottom of the separator filter to and Thur the oil tank lid. then to the air end. In this line approx. 1ft from the lid should be the orifice. make sure its clean. your high air end temp can be from several different problems. 1- low oil level from separator or scavenge line plugged. 2- A plugged oil cooler. Dirt and debris pushed against the cooler by the the cooling fan. This needs to be cleaned using a pressure washer. Wash in the opposite direction of air flow. Be careful with the pressure washer. You can damage the cooler. Low oil level and dirty coolers are the most common problems when getting high air end discharge temp shutdowns. However you could also have a bad thermal valve located where the three cooler lines come together. you will have to remove one line and 4 bolts. inside is the thermal element. You may also have a bad HAT switch (high air end temperature). It is located in the end of the air end and simply unscrews. I do not know of any adjustment.

SOURCE: 7.5 tas high airend temperature
1. Check your oil level, top up, or totally replace it
2. Check your cooler (Radiator looking thing) blow it out with a blow gun
3. Check your thermo valve (may need replacing)
4. Is the room that your compressor is in very warm, ambient air is a big factor in the running of your compressor
5. Do you have all the panels fitted to the machine? These are needed to aid airflow past your air-end
These are the main causes of high air end temperature. It may just need a good service
Hope this helps
