Symptom Possible Cause Possible Solution
Excessive snipe
(gouge in end of
board that is uneven
with rest of cut).
Note: A small
amount of snipe is
inevitable with all
types of planers. The
key is minimizing it
as much as possible.
1. Some snipe is inevitable.
2. Outfeed extension slopes down or is not
level with main table.
3. Workpiece is not supported properly as it
leaves planer.
4. Feed rollers and roller spring clogged with
material.
1. Plane lumber longer than your intended workpiece
length, then cut off excess after planing complete.
2. Adjust outfeed extension wing screws until wing is
level with main table.
3. Hold workpiece up slightly as it leaves outfeed end
of planer.
4. Clean feed rollers and roller springs (
Page 55).
Workpiece stops/
slows in middle of
cut. 1. Taking too heavy of a cut.
2. Pitch and glue build up on feed rollers. 1. Take a lighter cut.
2. Clean feed rollers with a pitch/resin dissolving
solvent.
Chipping (consistent
pattern). 1. Knots or conflicting grain direction in wood.
2. Taking too deep of a cut.
3. Feeding workpiece too fast.
4. Mis-adjusted chipbreaker.
5. Nicked or chipped knife.
1. Inspect workpiece for knots and grain direction;
only use clean stock, and cut WITH the grain.
2. Reduce depth of cut, especially when planing hard
woods.
3. Slow down feed rate.
4. Adjust both sides of chipbreaker to correct height.
5. Replace affected knife (
Page 45) or have it
sharpened.
Chipping/indentation
in workpiece surface
(inconsistent
pattern). 1. Chips aren't being properly expelled from
cutterhead.
1. Use a proper dust collection system.
Fuzzy grain. 1. Wood may have high moisture content.
2. Dull knives.
1. Verify moisture content is below 20%. Allow to dry
if moisture is too high.
2. Replace knives ( Page 45) or have them
professionally sharpened.
Long lines or ridges
that run along length
of board. 1. Nicked or chipped knife. 1. Replace knives ( Page 45) or have them
professionally sharpened.
Uneven cutting`
marks, wavy surface,
or chatter marks
across face of board. 1. Feeding workpiece too fast.
2. Knives not installed evenly.
3. Feed rollers set unevenly.
4. Worn cutterhead bearings.
1. Slow down feed rate.
2. Adjust knives with knife gauge (
Page 45); remove
knives, properly clean mounting channel, and re-
install (
Page 45).
3. Clean feed roller thoroughly; clean feed roller
springs (
Page 55).
4. Replace cutterhead bearings.
Glossy surface. 1. Knives are dull.
2. Feeding workpiece too slow.
3. Cutting depth too shallow.
1. Replace knives (
Page 45) or have them
professionally sharpened.
2. Increase feed rate.
3. Increase depth of cut.
