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.
Excessive snipe
Extension wing slope
down.
Adjust extension wing elevation.
Long workpiece is not
supported properly.
Use auxiliary rollers to support the 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 the depth of cut.
Planing end grain.
Do not plane end grain. Use a drum sander
instead.
Chipping in workpiece

Damaged cutter.
Rotate/replace cutter insert.
Planing against/across
grain; or knots.
Avoid planing workpieces with knots. Plane
with grain whenever possible. Moisten
problematic areas before planing.
Too much material

Indentation in
workpiece surface.
Dirty rollers.
Remove all buildups on infeed, outfeed, and
table rollers.
