The circular saw is very difficult and still smoking when cutting wood. What's the matter?
It's too fast. 500-750 turns is enough
Serrated opening is small, that is, sawtooth left one, the right one (terminology): small opening, easy to clamp saw, but also easy to saw blade and material friction, heating, smoke!
You change a saw blade, try it, maybe the saw blade is flat, and when you cut the thick wood, the friction is too big.
