  Use a 24-grit disc for less resistance, tighten flange nut to stop jamming.

  Check spindle lock, it is probably loose.

  Worn brushes causes stalling. Replace them, use a 24-grit disc, my Bosch grinder stopped stalling. Tighten flange nut for stability, clean spindle with alcohol for better spin.
