Possible Solution
5. Fix/replace fan cover; replace loose/damaged fan.

Possible Solution
1. Lower the bed rollers (Page 25).
2. Adjust the rear extension wing set screws to make

1. Inspect workpiece for knots and grain direction; use
only clean stock (Page 23).
2. Rotate/replace insert (Page 34).
3. Reduce feed rate (Page 24).
4. Reduce the depth of cut (Page 25).
5. Properly adjust the bed roller height (Page 25).
6. Adjust both sides of chip breaker to the correct
height (Page 38).
