Pushing the stock through the saw too slowly is a common cause of saw blade burn. Sometimes a blade that feels dull might only be dirty. If wood pitch resins build up behind the teeth of the blade, the cutting speed will slow down, increasing the chances for burns. Commercial blade cleaners are sold for this purpose.
