Problem Possible Cause Possible Solution
Workpiece came out
twisted.
Workpiece is twisted
before the cut.
Planer is not the tool to flatten a twisted
workpiece. Flatten one side with a jointer before
proceeding with a planer.
Feed/bed roller is not
parallel with the
cutterhead.
Adjust roller/table parallelism.
Excessive snipe Extension tables slope
down.
Adjust the extension tables to make them
parallel with the planer bed.
Long workpiece is not
supported properly.
Use auxiliary rollers to support long workpiece.
A small amount of
sniping can happen
sometimes.
Add an extra 6” length on a workpiece for
planing, and then trim off the ends.
End of workpiece
chipping
Aggressive depth of cut
for the wood type.
Reduce depth of cut.
Planing end grain. Do not plane end grain. Use a drum sander
instead.
Chipping in workpiece
surface.
Damaged cutter. Rotate/replace cutter insert.
Planing against/across
grain; or knots.
Avoid planing workpiece with knots. Plane along
the grain and perform downhill cut whenever
possible. Moisten problematic areas before
planing.
Too much material
removed in one pass.
Reduce feed rate / depth of cut.
Indentation in
workpiece surface.
Dirty rollers. Remove all buildups on infeed, outfeed, and
table rollers.
Inefficient chip
removal.
Check dust collection system for suction.
Adjust chip breaker and chip deflector.
Fuzzy looking finish. Wood moisture content
too high.
Only process wood with less than 20% moisture
content.
Dull cutter. Rotate/replace cutter insert.
Some wood types tend
to have fuzzy grain.
Adjust feed rate / depth of cut.
Use sharp cutters.
Glossy looking finish. Dull cutter. Rotate/replace cutter insert.
Cutting depth too
shallow.
Increase depth of cut.
Long line or ridges
running along the
length of board.
Chipped cutter. Rotate/replace cutter insert.
Serrated marks on
workpiece.
Cutting depth too
shallow.
Increase depth of cut.
