I purchased a Hill EVO-310 sometime last year. It worked perfectly since I purchased it, until yesterday. I tried to top-off my air tank from ~220-310 bars as I normally would. Usually, I start the compressor and let it pre-charge to a pressure close to the tank pressure before opening the tank valve.
Problem: Now the unit only pre-charges to about 85 bars and then hangs there. After about 10-20 seconds or so the dump valve blows open blowing the disk off of the rubber boot. This happened three times in a row. Has anyone seen this issue before? If so, what did you do to correct the issue?
BTW: Oil and silicone levels are normal. I currently have a little over 12 hours on it so far.
