I have had the above tool for a few years now and it suddenly stopped working for no apparent reason. I contacted Gesswein hoping they’d help me troubleshoot and fix whatever’s wrong with it on my own, but no dice–they want me to ship it back for an estimate on the cost of repair. I’d rather spend that money on a new micro motor that also supports a hammer handpiece rather than pouring it down an uncertain repair rabbit hole without any means of verification.
All thoughts on the troubleshooting/repair/replacement issue welcome–I paid in the $200 range for the tool originally and it has served me well. I could try to fix it myself, but Gesswein did not respond when I asked for more detailed schematic information than shipped in the box. Thanks in advance for any and all advice!
