workpiece as it leaves cutterhead.
1. Align outfeed table with cutterhead knife at top dead

3. Workpiece not suitable for jointing.
4. Feeding workpiece too fast.
5. Excessive cut depth.
6. Lack of proper dust collection or clogged
dust port.

2. Sharpen/replace knives ( Page 47).
3. Ensure workpiece is suitable for jointing (
Page 26).
4. Reduce feed rate.
5. Reduce cut depth (
Page 31).
