i borrowed a dw dw733 planer today. tried to surface some cypress,soft wood--should go pretty good right? well i had to help feed it through.knifes leaving burn marks,and what a racket that thing makes. imthinking dull blades. am i on track here with that thought...im only taking a 1/16 -3/32 per pass so i dont think thats the problem. also to youguys who have this model,how do you read the clear height indicator,i would think there should be a line in it somewhere to line up...mabie its faded,or mabie i need to get out my glasses:lol::lol:
