Bosch PMF 180e multi tool just stopped working today.
(The same apply for PMF 190e)
I was using my Bosch PMF 180e today and it just stopped.
It was strange that it gave up the ghost without smelling burnt or being hot at all.
I had been using it for 10 minutes doing some light DIY.
I decided to open it up to check out what could be wrong.
9 x screws keep it together (see red circles). I used a normal flat headed screwdriver.
I could not see anything wrong after I've opened it. I used a multimeter in order to check for continuity through the cable and to the coil. Everything was ok. I removed then the 2 screws (red circle) to be able to remove the circuit board.
I checked for continuity between the orange cable which was connected to the coil (without red circle) and the blue cable connected to the coil. It was ok.
Then I checked the other pair (white cable and the orange cable with red circle). There was no continuity. I realised then that the winding connections had snapped (the thin bit of wire winding where it joins the connector within the red circle).
I soldered the wire winding to the connector and put the multi tool together again.
Surprise, it worked again.
I think vibration could be a problem for this kind of tool an most probably the reason for the failure.
