Good morning, it’s not so nice to write about a problem right now, if you experience the terrible earthquake in Turkey/Syria life, please excuse me. As you can see, I’m new here and as always you often register at a forum only if you can’t keep going. For several years now I have been the owner of this machine. Initially the error E1, so the contact that the hood is not closed, I could get out of the pdf file, which kindly Snap On g A year ago the error E2 – maximum speed not reached – came. After I cleaned the optoelectronics, it went again. But now the error comes again, clean does nothing. If I see the “bollen heavy” machine, I think actually this is a machine that can not break, heavy mechanical engineering. Okay, here too is electronics contained, but relatively manageable. Nevertheless, there are a few hurdles that already start with 5 pots, where I think that maybe a little bit could be turned here. Or the optodiodes don’t shine so great anymore. There’s also a pot with “P”, could be called “Power”? Does anyone possibly have a tip where else I could look for? The diodes might be measured? At the first start without a wheel the machine slows down, that is, it finds the maximum speed. If it doesn’t fix the speed, it runs out. Thanks in advance for the right tip. Maybe even someone has a Set-up instructions.
