6. Bed rollers protruding unevenly.
7. Motor bearings at fault.
8. Cutterhead bearings at fault.
9. Centrifugal switch is at fault.
10. Chip deflector hitting cutterhead.
5. Fix/replace fan cover; replace loose/damaged fan.
6. Adjust bed rollers (
Page 25).
7. Test by rotating shaft; rotational grinding/loose shaft
requires bearing replacement.

Machine Operation
Symptom
Possible Cause
Possible Solution
Excessive snipe
(gouge at the end of
the workpiece that
is uneven with the
rest of the cut).
Note: A small
amount of snipe
is inevitable
with all types of
planers—the key is
to minimize it.
1. One or both of the bed rollers are set too
high.
2. Rear extension wing slopes down or is not
level with main table.
3. Chip breaker or pressure bar set too low.
4. Workpiece is not properly supported as it
leaves the planer.
1. Lower the bed rollers (
Page 25).
2. Adjust the rear extension wing set screws to make
the extension level with the main table (
Page 16).
3. Raise the height of the chip breaker or pressure bar
(
Page 38).
4. Use an assistant or roller beds/stands to properly
support the workpiece as it leaves the planer.
Workpiece stops/
slows in the middle
of the cut.
1. Depth of cut too deep.
2. Pitch and glue build-up on planer
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 (
Page 25).
2. Clean planer components with a pitch/resin dissolving
solvent.
3. Lower/raise the bed rollers (
Page 25).
4. Raise the height of the chip breaker or pressure bar
(
Page 38).
5. Adjust the feed rollers to the correct height (
Page
38).
Consistent chipping
pattern.
1. Knots or conflicting grain direction in
workpiece.
2. Nicked or chipped insert.
3. Feed rate too fast.
4. Depth of cut too deep.
5. Bed rollers set too high or low; not even with
each other.
6. Misaligned chip breaker.
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).
