Possible Cause
1. Outfeed table is out of alignment with
the cutterhead.
2. Operator is pushing down on trailing
edge of the workpiece
1. Cutterhead belt is damaged/broken.
1. Cutterhead is set lower than the
outfeed table.
1. Knots or conflicting grain direction in
wood.
2. Nicked or chipped knives.
3. Feeding workpiece too fast.
4. Taking too deep of a cut.
1. Nicked or chipped knives.
1. Feeding workpiece too fast.
2. Knives not adjusted evenly with each
other 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.
1. Knives are out of alignment or
cutterhead height is not even with the
outfeed table.
2. Fence stops are set incorrectly.
3. Fence bracket parts are loose or parts
are misaligned.
Possible Solution
1. Align
cutterhead
with
(Page 17).
2. Reduce/eliminate downward pressure on that
end of the workpiece.
1. Replace cutterhead belt (Page 33).
1. Align the cutterhead knives with the outfeed
table at top dead center (Page 17).
1. Inspect workpiece for knots and grain; only
use clean stock (Page 21).
2. Adjust one of the nicked knives sideways;
sharpen or replace blade (Page 35).
3. Slow down the feed rate.
4. Take a smaller depth of cut. Never exceed
per pass. Reduce cutting depth when working
with hard woods.
1. Adjust one of the nicked knives sideways;
sharpen or replace blade (Page 35).
1. Slow down the feed rate.
2. Adjust the knives so they are set up evenly
with the cutterhead (Page 35).
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
(Page 26).
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.
1. Reset the knives to correct height and alignment
with cutterhead assembly (Page 17).
2. Recalibrate the fence stops (Page 23).
3. Check/tighten the fence bracket fasteners
(Page 16).
