PROBLEM
POSSIBLE CAUSE
CORRECTIVE ACTION
Table(s) difficult
to adjust.
1. Table lock(s) engaged/partially engaged.
2. Infeed table stops blocking movement.
1. Completely loosen table lock(s) (
Page 30
).
2. Loosen/reset infeed table stops (
Page 30
).
Excessive snipe
(gouge in end
of board that is
uneven with rest
of cut).
1. Outfeed table set too low; or knives set too
high.
2. Operator pushing down on trailing end of
workpiece as it leaves cutterhead.
1. Align outfeed table with cutterhead knife at top
dead center (
Page 25
); adjust height of knives
evenly with outfeed table (
Page 25
).
2. Focus most of the workpiece pressure against
outfeed table while cutting.
Workpiece stops
in middle of cut.
1. Outfeed table set too high.
1. Align outfeed table with cutterhead knife at top
dead center (
Page 25
).
Workpiece chip-
ping, tear-out, or
overall rough cut.
1. Not feeding workpiece to cut "with the
grain."
2. Dull knives.
3. Workpiece not suitable for jointing.
4. Nicked or chipped knives.
5. Feeding workpiece too fast.
6. Excessive cut depth.
7. Lack of proper dust collection or clogged
dust port.
1. Turn the workpiece 180° before feeding again.
2. Sharpen/replace knives (
Page 40
).
3. Ensure workpiece is suitable for jointing (
Page 29
).
4. Sharpen/replace knives (
Page 40
).
5. Reduce feed rate.
6. Reduce cut depth (
Page 30
).
7. Clear blockages, ensure dust collector is operating
efficiently; upgrade dust collector.
Fuzzy grain.
1. Wood has high moisture content.
2. Dull knives.
1. Ensure wood moisture content is less than 20%.
Allow to dry if necessary.
2. Sharpen/replace knives (
Page 40
).
Long lines or
ridges that run
along length of
workpiece.
1. Nicked or chipped knives.
2. Loose or incorrectly installed knives.
1. Sharpen/replace knives (
Page 40
).
2. Remove/replace knives/individual blade, and
install properly (
Page 40
).
Uneven cutter
marks, wavy
surface, or
chatter marks
across face of
workpiece.
1. Feeding workpiece too fast.
2. Knives not adjusted at even heights in
cutterhead.
1. Reduce feed rate.
2. Adjust knives so they are set up evenly in
cutterhead (
Page 40
). Remove, clean, and re-
install any knife that is "raised" in cutterhead.
Glossy surface;
scorching or
burn marks on
workpiece.
1. Dull knives.
2. Feed rate too slow.
1. Sharpen/replace knives (
Page 40
).
2. Increase feed rate.
Workpiece is
concave or
convex along
its length after
jointing.
1. Workpiece not held with even pressure
against outfeed table during cut.
2. Workpiece too uneven at start of operation.
3. Outfeed table not parallel with infeed table.
1. Apply even downward pressure against workpiece
throughout entire travel along outfeed side during
cut.
2. Take partial cuts to remove extreme high spots
before doing a full pass.
3. Check/Adjust table parallelism (
Page 47
).
