Chipping.
Fuzzy Grain.
Long lines or ridges that
run along the length of the
board.
Uneven cutter marks, wavy

across the face of the
board.
Board edge is concave or
convex after jointing.
POSSIBLE CAUSE
1. Motor or component is loose.
2. Knife blades, clamp or jack screws
are at fault.
3. Belts worn or loose.
4. Motor fan is rubbing on fan cover.
5. Loose mounting bolts.
6. Blade is at fault.
POSSIBLE CAUSE

2. Operator pushing down on trailing
end of the workpiece.
1. Knives set too low.
1. Knots or conflicting grain direction
in wood.
2. Nicked or chipped blades.
3. Feeding workpiece too fast.
4. Taking too deep of a cut.
1. Wood may have high moisture con-
tent or surface wetness.
2. Dull knives.
1. Nicked or chipped knives.
1. Feeding workpiece too fast.
2. Knives not adjusted at even heights
in the cutterhead.
1. Board not held with even pressure
on infeed and outfeed table during
cut.
2. Board started too uneven.
3. Board has excessive bow or twist
along its length.
4. Insufficient number of passes.
CORRECTIVE ACTION
1. Inspect/replace stripped or damaged bolts/nuts,
and re-tighten with thread locking fluid.
2. Resharpen/replace knives as required; set knife
alignment correctly
3. Inspect/replace belts with a new ones
4. Replace dented fan cover; replace loose/damaged
fan.
5. Replace/tighten as required.

dull blade.
CORRECTIVE ACTION
1. Set the knives just even with the outfeed table when
they're at top dead center (Page 32).
2. Reduce/eliminate downward pressure on that end of
workpiece.
1. Set the knives just even with the outfeed table when
they're at top dead center (Page 32).
1. Inspect workpiece for knots and grain (Page 22);
only use clean stock.
2. Adjust one of the nicked knives sideways; replace
knives (Page 32).
3. Slow down the feed rate.
4. Take a smaller depth of cut. (Always reduce cutting
depth when surface planing or working with hard
woods.)
1. Check moisture content and allow to dry if moisture
is over 15%.
2. Replace knives (Page 32).
1. Sharpen or replace knives (Page 32).
1. Slow down the feed rate.
2. Adjust the knives so they are set up evenly in the
cutterhead (Page 32).
1. Hold board with even pressure as it moves over the
cutterhead.
2. Take partial cuts to remove the extreme high spots
before doing a full pass.
3. Surface plane one face so there is a good surface to
position against the fence.
4. It may take 3 to 5 passes to achieve a perfect edge,
depending on the starting condition of the board and
the depth of cut.
