Few days ago member here reported that backing plate flew off his Festool RO 150 FEQ while 95% in the job. That thread is here: http://autopia.org/forum/machine-polishing/94878-festool-rotex-150-fe-users-beware.html
At that point in time I could not see how that can happen. Well, as of this weekend I can see how that can happen because bp on my own 150 FEQ flew off on me. However, when it did that tool was not operating under conditions it was exactly designed for.
Tool was in random orbit mode. I was working with it for a while at speed 1. Metal part of "dust extraction port" was heating up due to it, as well as rest of the tool, and I could feel it (I was working with handle off). I have decided to lift the tool of the paint and run it a little bit in the air at speed 6 to increase air flow and cool it down. Some 15 seconds later or so bp separated itself from the tool and flew off.
Thank God nobody was hit and nothing was damaged due to it. I have taken a look at it and separation was not due to mechanical failure. Also bp did not separate itself for a while prior to it, it did it in those seconds when it was at full speed in the air.
Therefore it seems to be due to fact that no resistance against pad on one side with being thrown back and forth due to inertia on other side alllowed bp to wiggle itself eventually free.
Once bp was put back on it continued being used without any further failures. However, I was not using it at speed 6 so that factor might still remain.
I will be trying to contact Festool on this matter.
