Model G0815 (Mfd. Since 09/18)
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
planers. The key
is minimizing it as
much as possible.
1. Chipbreaker set too low.
2. Workpiece is not supported as it leaves
planer.
3. Some snipe is inevitable.
1. Raise height of chipbreaker (
Page 39).
2. Hold workpiece up slightly as it leaves outfeed end
of planer.
3. Plane lumber longer than your intended workpiece
length, then cut off excess after planing complete.
Workpiece stops/
slows in middle of
cut.
1. Taking too deep of a cut.
2. Chipbreaker set too low.
3. Feed rollers set too low or too high.
4. Pitch and glue build up on planer
components.
1. Take a smaller depth of cut. (Reduce cutting depth
when planing hard woods.)
2. Raise height of chipbreaker (
Page 39).
3. Lower/raise feed rollers (
Page 39).
4. Clean internal planer components 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. Feed rate set 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. (Always reduce cutting depth
when planing hard woods.)
3. Slow down feed rate (
Page 25).
4. Adjust both sides of chipbreaker to correct height
(
Page 39).
5. Replace affected knife (
Page 25), or have it
sharpened.
Chipping/indentation
in workpiece surface
(inconsistent
pattern).
1. Chips aren't being properly expelled from
cutterhead.
2. Chip breaker not set correctly.
1. Use a proper dust collection system (
Page 19).
2. Correctly adjust chip breaker (
Page 39).
Fuzzy grain.
1. Wood may have high moisture content or
surface wetness.
2. Dull knives.
1. Check moisture content is below 20% and allow to
dry if moisture is too high.
2. Replace knives (
Page 25) or have them
professionally sharpened.
Long lines or ridges
that run along length
of board.
1. Nicked or chipped knife.
1. Replace knives (
Page 25) or have them
professionally sharpened.
Uneven cutting`
marks, wavy surface,
or chatter marks
across face of board.
1. Feed rate set too fast.
2. Chipbreaker set unevenly or not low
enough.
3. Knives not installed evenly in cutterhead.
4. Worn cutterhead bearings.
1. Slow down feed rate (
Page 25).
2. Adjust height of chipbreaker (
Page 39).
3. Adjust knives with knife-setting gauge (
Page 25).
4. Replace cutterhead bearings.
Glossy surface.
1. Dull knives.
2. Feed rate set too slow.
3. Cutting depth too shallow.
1. Replace knives (
Page 25) or have them
professionally sharpened.
2. Increase feed rate (
Page 25).
3. Increase depth of cut (
Page 24).
If workpiece twists in
machine.
1. Feed rollers not parallel with table.
1. Adjust feed rollers (
Page 39).
