Yes, you would be barking up the right tree

MIGHT CAN HELP. NOT AN I.R. EXPERT BUT KNOW A GOOD BIT ABOUT SCREW COMP. ARE YOU SHUTTING UNIT DOWN SUDDENLY WITH EMERGENCY STOP OR SOMETHING. SOME UNITS DO THIS MORE THAN OTHERS BECAUSE THE WAY THE VALVE CLOSES. BURPING OIL THROUGH THE INTAKE IS ALSO CAUSED BY SUDDEN STOP INSTEAD OF THE UNIT SLOWLY SHUTTING DOWN AND THE OIL IS RUNNING BACK SLOWLY. THE UNIT ACTUALLY TURNS BACKWARDS A LITTLE BIT. YOUR OIL SHOULD NOT COST THAT MUCH. YOU CAN CONTACT ME FOR PARTS AND PRICING ON THE OIL. YOU CAN SAVE ALOT OF MONEY WITH AFTERMARKET SERVICE PARTS AND OIL -THEYRE JUST AS GOOD AS OEM.I WOULDNT USE 30W OIL ! YOUR POOR AIR DELIVERY MAY BE AFFECTED BY WORN PARTS DUE TO LUBRICATION. HOW OLD IS UNIT? MODEL # ? CONTACT ME [email protected] FOR INFO & PRICING. ME AND 1 TECH WOULD PROBABLY COME DOWN AND FIX IT FOR YOU FOR AN ALL EXPENSE TRIP FOR FREE. WE ARE IN NC AND DONT GET OUT ENOUGH.

I am assuming this has a Intellisys controller.

Look for any problem involving a dropped phase of the input power. It could be a transient one such as a poor contact that the sensor detects a glitch which then cures itself when you overide the watchdog of the system. Tighten all electrical connections and while doing so look for any heating indicators such as discolored insulation. The electronics can see very short failures that are punched through when running manually. That is what the smart controllers are for to protect the motor. The controller itself probably only uses one phase for its own power. The transient might happen in a tenth of a second.

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.

Hi, Yes there is a key combination on these, but it depends on the controller that i fitted onto it, is it an Intelisis with the 3 Oval buttons with the up and down arrows in the middle of them? If so, as you look at the left hand Oval button, just to the left of that is an invisible button. you need to press/swipe your thumb from the far left of the controller, going over the invisible button, to the left hand oval button. pressing both buttons in the process. Hope that helps
