Hello everybody,

I bought Erbauer ER2100 at an auction some time ago.
When I received it, it was not working. I removed the top and noticed the brushes were disintegrated therefore I replaced them with these ones on Ebay
Once replaced the brushes, the router started working but I can see sparks from the motor as this video shows.

Is that normal or there is something wrong with it?

Many thanks
Alberto

Last time I replace brushes in a router, they also sparked until the end of the brushes was ground down to the curve of the spinning center

I was thinking the same but as I am no expert I made the question. I will try the suggestion from TenGees any way and report the outcome.
