wingless' Bosch 1581vs Jigsaw Brush Cleaning

Recommended Posts

My Bosch 1581vs didn't want to work tonight.


When the trigger was squeezed the jigsaw would give a few sluggish pumps, then stop.


This is a great tool for disassembly / inspection / repair. Easy to open / close.


The skins were removed, AC power restored, then the trigger carefully squeezed. An AC sniffer was used to verify power through the switch and through the adjustable speed controller, pointing to the brushes being the problem for no rotation.


The motor was manually jogged, the trigger squeezed again, this time sluggish rotation was observed, along w/ abundant sparks from one of the brushes. That brush was removed, then the surface lightly cleaned w/ smooth emery paper.


Now the tool again works normally.
