Symptom Possible Cause Possible Solution
Machine has
vibration or noisy
operation. 1. Motor or component loose.
2. V-belt worn,loose, or slapping cover.
3. Pulley loose.
4. Plastic chip deflector hitting knives.
5. Motor fan rubbing on fan cover.
6. Knives/gibs at fault.
7. Cutterhead bearings at fault.
8. Motor bearings at fault.
1. Inspect/tighten loose bolts/nuts; replace damaged
components.
2. Tension/replace belt (
Page 39).
3. Re-align/replace shaft, pulley set screw, and key.
4. Adjust chip deflector (
Page 43); replace if
necessary.
5. Fix/replace fan cover; replace loose/damaged fan.
6. Sharpen/replace knives; set knife alignment/height
correctly (
Page 27).
7. Replace bearing(s).
8. Test by rotating shaft; rotational grinding/loose
shaft requires bearing replacement.

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. Outfeed extension slopes down or is not
level with main table.
2. Workpiece is not supported as it leaves
planer.
3. Some snipe is inevitable.
1. Shim outfeed extension wing level with main table.
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 heavy of a cut.
2. Feed rollers set too low or too high.
3. Pitch and glue buildup on planer
components.
1. Take a lighter cut.
2. Adjust feed rollers (
Page 40).
3. 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. 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. Replace affected knife (
Page 27) or have it
sharpened; rotate/replace insert ( Page 29).
Chipping/indentation
in workpiece surface
(inconsistent
pattern). 1. Chips aren't being properly expelled from
cutterhead.
1. Use a proper dust-collection system.
