Excessive step
(snipe)
(gouge at the end
of the workpiece
that is uneven with
the rest of the cut).
1. One or both of the bed rollers are
set too high.
2. Rear table extension slopes down or
is not level with the table
3. Chip breaker or pressure bar set too
low
4. Workpiece is not fully supported as it
leaves the thicknesser.
1. Lower the bed rollers
2. Adjust the rear extension wing set screws
to make the extension level with the table
3. Raise the height of the chip breaker or
pressure bar
4. Use a roller stands to properly support the
workpiece as it leaves the thicknesser.
Workpiece stops/
slows in the middle
of the cut.
1. Depth of cut too deep.
2. Pitch/glue build-up on thicknesser
components.
3. One or both of the bed rollers are set
too low or too high.
4. Chip breaker or pressure bar set too
low
5. Feed rollers set too low or too high.
1. Reduce the depth of cut.
2. Clean planer components with a pitch/
resin dissolving solvent.
3. Lower/raise the bed rollers
4. Raise the height of the chip breaker or
pressure bar
5. Adjust the feed rollers to the correct height
