G0453W/ZW–G0454W/ZW (Mfd. Since 05/16)
Symptom Possible Cause Possible Solution
Machine has
vibration or noisy
operation. 7. Knives/gibs at fault.
8. Motor bearings at fault.
9. Cutterhead bearings at fault.
7. Sharpen/replace knives; set knife alignment/height
correctly ( Page 27).
8. Test by rotating shaft; rotational grinding/loose
shaft requires bearing replacement.
9. Replace bearing(s).
Motor & Electrical (Continued)
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. Chipbreaker/pressure bar set too low.
4. Workpiece is not supported as it leaves
planer.
5. Some snipe is inevitable.
1. Lower bed rollers ( Page 42).
2. Shim outfeed extension wing level with main table.
3. Raise height of chipbreaker or pressure bar
( Page 42).
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. Chipbreaker or pressure bar set too low.
4. Feed rollers set too low or too high.
5. Pitch and glue build up on planer
components.
1. Take a lighter cut.
2. Lower/raise bed rollers (
Page 42).
3. Raise height of chipbreaker or pressure bar
( Page 42).
4. Lower/raise feed rollers ( Page 42).
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 chipbreaker.
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 chipbreaker to correct height.
5. 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.
2. Chip breaker not set correctly.
1. Use a proper dust collection system.
2. Correctly adjust chip breaker ( Page 42).
Fuzzy grain. 1. Wood may have high moisture content or
surface wetness.
2. Dull knives/inserts.
1. Check moisture content is below 20% and allow to
dry if moisture is too high.
2. Replace knives ( Page 27) or have them
professionally sharpened; rotate/replace inserts
(
Page 29).
Long lines or ridges
that run along length
of board. 1. Nicked or chipped knife/inserts. 1. Replace knives (
Page 27) or have them
professionally sharpened; rotate/replace inserts
(
Page 29).
