The buildup of dirt and resin behind the saw blade teeth slows the speed of cutting and increases the wood burn chances.
2. Inaccurate Feed Speed

Take time to know the feel suitable to the wood types and place the right speed feed. Inaccuracy in the speed feed is the reason causing burn marks on the wood.

Replace the Blade
Warped or broken blades are the wood burn problem source. If you notice the wood burn marks, remove the blade after unplugging and look closely.
If not, take it to a professional and examine it to know if replacing the blade is essential.
Woodcut faster with a saw leaves no chances of burn marks. It is annoying to cut faster as it results in less smooth cuts. However, with experience, you can get the right balance.
Wood having burn marks is hard to eliminate. The common reason is the blade in the saw. You may visit the local hardware store or align the blade to avoid wood burn.
