Possible Solution
1. Replace cutter, or have it professionally sharpened.
2. Increase feed speed (Page 25).
3. Clean cutter with blade and bit cleaning solution.
4. Reverse direction of cutter rotation/reverse feed
direction (Page 25).
5. Make several passes of light cuts.
1. Check moisture content and allow to dry if moisture is
more than 20%.
2. Replace cutter, or have it professionally sharpened.
1. Cut with grain of wood.
2. Replace cutter, or have it professionally sharpened.
3. Decrease feed rate.
4. Take a smaller depth of cut. (Always reduce cutting
depth when working with hard woods.)
5. Inspect workpiece. Use a different workpiece if
necessary.
1. Move smoothly or use a power feeder.
2. Apply constant pressure.
3. Adjust fence (Page 27).
1. Make several passes of light cuts.
2. Inspect workpiece; only use smooth, dry stock without
large/loose knots.
3. Ensure proper clearance between cutter, guard, and
table.
1. Feed workpiece in opposite direction of cutterhead
rotation.
1. Adjust fence (Page 27). Align fence boards with
straightedge, verify parallelism (Page 50).
1. Adjust outfeed/infeed fence parallelism to support
workpiece as it passes cutterhead (full face removal)
(Page 50).
2. Apply even pressure to workpiece throughout cut and
use featherboards or power feeder.
