Brushes aren't much money, so worth trying anyway -def sounds like brushes.

I think brushes mostly have a limiting wire so when the carbon wears down, there becomes a point where the limiting wire is taught and stops the carbon seating fully on the armature and creates sparking.

^^ yup, this is whats happeneing, had a similar issue years ago with my previous smaller mitre saw. It may have even come with spares, check the box again - or whichever drawer is the junk drawer in your house .

A word to the wise - you can source new brushes for A LOT less than I've seen advertised in places - things like £5 a pair etc... remove one and make a note of its shape then google replacement brushes - you'll get lots of hits from chinese manufacturers of brushes with various shapes - check the dimensions, find a match and buy a set or more. I managed to get a box of 20 brushes for less than a single pair costs over here. Sold half of them to boot
