Excessive snipe (gouge in the
end of the board that is uneven
with the rest of the cut). 1. Outfeed table is out of alignment with
the cutterhead.
2. Operator is pushing down on trailing
edge of the workpiece
1. Align cutterhead with outfeed table.
2. Reduce/eliminate downward pressure
on that end of the workpiece.
Cutterhead stops during opera-
tion. 1. Cutterhead belt is damaged/broken. 1. Replace cutterhead belt.

wood.
2. Nicked or chipped knives.
3. Feeding workpiece too fast.
4. Taking too deep of a cut.
1. Inspect workpiece for knots and grain;
only use clean stock.
2. Adjust one of the nicked knives side-
ways; sharpen or replace blade.
3. Slow down the feed rate.
4. Take a smaller depth of cut. Never
exceed 1/8" per pass. Reduce cut-
ting depth when working with hard
woods.
Long lines or ridges that run
along the length of the board. 1. Nicked or chipped knives. 1. Adjust one of the nicked knives side-

infeed and outfeed table during cut.
2. Board started too uneven.
3. Board has excessive bow or twist

4. Insufficient number of passes.
1. Hold board with even pressure as it
moves over the cutterhead.

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.
Overall, cut quality is poor;
inconsistent snipe problems;
or consistent difficulty feeding
workpiece. 1. Knives are out of alignment or
cutterhead height is not even with the
outfeed table.
2. Jointer stops are set incorrectly.
3. Fence bracket parts are loose or parts

alignment with cutterhead assembly.
2. Recalibrate the fence stops.
