My search skills are rubbish i know,,,,, uk 4.6 eas compressor running continously pretty much - piston seal cream crackered replaced still keen to run way too long swapped for known good compressor - sorted but then an eas fault cropped up - hadn;t had to use my RSW software for years (also have an MSV EXTREME) and couldn't initially find the handbook i downloaded so played with what i could remember and ended up deleting all settings then used figures that gave me way off settings and eventually standard setting that was akin to extended height now found the electronic handbook but cannot see where it mentions what the HEIGHTS tab would be used for to get heights when the CALIBRATE does this doesn't it? and i'm confused about what, on the FAULTS tab the boxes labelled F8 F9 FA FB and FC mean... any ideas anyone please
