Adjust blade guides properly
Use thinner blade
Replace blade
•Use finer tooth blade
Gently increase pressure
Reduce speed; increase rate of feed for
scale and change blades for hard spots
Remove blade, twist inside out and reinstall
blade
Use miter gauge; adjust tilt of table at 90 °
Reduce rate of feed
Move both guide blocks within .002" from
