PROBLEM
POSSIBLE CAUSE
CORRECTIVE ACTION
Excessive snipe (gouge in
the end of the board 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 minimizing it as much as
possible.
1. One or both of the bed rollers are
set too high.
2. Outfeed extension slopes down or
is not level with the main table.
3. Chipbreaker or pressure bar set
too low.
4. Workpiece is not supported as it
leaves the planer.
1. Lower the bed rollers (
Page
20
).
2. Shim the outfeed extension wing level with the
main table.
3. Raise the height of the chipbreaker or pressure bar
(
Page 31
).
4. Hold the workpiece up slightly as it leaves the
outfeed end of the planer.
Workpiece stops/slows in
the middle of the cut.
1
. Taking too heavy of a cut.
2. One or both of the bed rollers are
set too low or too high.
3. Chipbreaker or pressure bar set
too low.
4. Feed rollers set too low or too
high.
5. Table not parallel with headstock.
6. Pitch and glue build up on planer
components.
1
. Take a lighter cut.
2. Lower/raise the bed rollers (
Page 20
).
3. Raise the height of the chipbreaker or pressure bar
(
Page 31
).
4. Adjust the feed rollers to the correct height (
Page
31
)
5. Adjust the table so it is parallel to the headstock.
6. Clean the internal cutterhead components with a
pitch/resin dissolving solvent.
Chipping (consistent pat-
tern).
1. Knots or conflicting grain direction
in wood.
2. Nicked or chipped knife.
3. Feeding workpiece too fast.
4. Taking too deep of a cut.
5. Misaligned chipbreaker.
1. Inspect workpiece for knots and grain direction;
only use clean stock.
2. Replace the affected knife (
Page 27
).
3. Slow down the feed rate (
Page 19
).
4. Take a smaller depth of cut. (Always reduce cut-
ting depth when surface planing or working with
hard woods.)
5. Adjust both sides of the chipbreaker to the correct
height (
Page 35
).
Fuzzy grain.
1. Wood may have high moisture con-
tent or surface wetness.
2. Dull knives.
1. Check moisture content and allow to dry if mois-
ture is too high.
2. Rotate/replace the knives (
Page 27
) or have them
professionally sharpened.
Long lines or ridges that
run along the length of
the board
1. Nicked or chipped knife(s).
1. Replace the knives (
Page 27
) or have them profes-
sionally sharpened.
Uneven knife marks, wavy
surface, or chatter marks
across the face of the
board.
1. Feeding workpiece too fast.
2. Chipbreaker or pressure bar set
unevenly.
3. Knives not installed evenly.
4. Worn cutterhead bearings.
1. Slow down the feed rate.
2. Adjust the height of the chipbreaker or pressure
bar (
Page 31
).
3. Adjust the knives with the knife gauge (
Page 27
).
4. Replace cutterhead bearings.
Glossy surface.
1. Knives are dull.
2. Feed rate too slow.
3. Cutting depth too shallow.
1. Rotate/replace the knives (
Page 27
) or have them
professionally sharpened.
2. Increase the feed rate (
Page 19
).
3. Increase the depth of cut.
Chip Marks (inconsistent
pattern).
1. Chips aren't being properly
expelled from the cutterhead.
1. Use a dust collection system; adjust the chip
deflector in or out depending on your setup (
Page
35
).
