Symptom Possible cause Possible Solution
Machine has
vibration or noisy
operation. 1. Motor or component loose.
2. V-belt(s) worn,loose, or slapping cover.
3. pulley loose.
4. Bed rollers protruding unevenly.
5. plastic chip deflector hitting knives.
6. Motor fan rubbing on fan cover.
7. Knives/gibs at fault.
8. Cutterhead bearings at fault.
9. Motor bearings at fault.
1. inspect/tighten loose bolts/nuts; replace damaged
components.
2. tension/replace belts as a matched set (
Page 41).
3. re-align/replace shaft, pulley set screw, and key.
4. adjust bed rollers (
Page 27).
5. adjust chip deflector ( Page 47); replace if
necessary.
6. Fix/replace fan cover; replace loose/damaged fan.
7. Sharpen/replace knives; set knife alignment/height
correctly ( Page 28).
8. replace bearing(s).
9. test by rotating shaft; rotational grinding/loose
shaft requires bearing replacement.
Motor & Electrical (cont.)
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. one or both of bed rollers are set too high.
2. outfeed extension slopes down or is not
level with main table.
3. Chip breaker set too low.
4. Workpiece is not supported as it leaves
planer.
5. Some snipe is inevitable.
1. lower bed rollers ( Page 27).
2. Shim outfeed extension wing level with main table.
3. raise height of chip breaker (
Page 43).
4. hold workpiece up slightly as it leaves outfeed end
of planer.
5. 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 heavy of a cut.
2. one or both of bed rollers are set too low or
too high.
3. Chip breaker or pressure bar set too low.
4. Feed rollers set too low or too high.
5. pitch and glue buildup on planer
components.
1. take a lighter cut.
2. adjust bed rollers (
Page 27).
3. raise height of chip breaker or pressure bar
(
Page 43).
4. adjust feed rollers ( Page 43).
5. Clean internal cutterhead 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. Feeding workpiece too fast.
4. Mis-adjusted chip breaker.
5. nicked or chipped knife/insert.
1. inspect workpiece for knots and grain direction;
only use clean stock, and cut With the grain.
2. take a smaller depth of cut. (reduce cutting depth
when planing hard woods.)
3. Slow down feed rate.
4. adjust both sides of chip breaker to correct height.
5. replace affected knife (
Page 28), or have it
sharpened; rotate/replace insert ( Page 31).
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.
2. Correctly adjust chip breaker ( Page 43).
