Operating Controls

The stop button is a mushroom style button
which is convenient for "emergency" shutdowns.
After being pushed, the stop button remains
engaged. To re-start the planer, twist the stop
button clockwise until it pops back out.
Test Cutting and
Troubleshooting
Using a piece of semi-finished stock, set up for a
1/16" (1.59mm) deep cut with the quick-set table
roller adjustment (shown in Figure 16) set at
zero. Start the machine and, standing to one
side of the table, begin feeding the stock into the
machine.
Never stand directly in line
with stock or allow anyone else to do so, and
do not bend down to see how stock is
feeding. Should a kickback occur, serious or
fatal injury could result.
The infeed roller should take the material and
force it under the chipbreaker and cutterhead. If
the material feeds through effortlessly, examine
the finished cut carefully for imperfections.
Learning to read a board for imperfections will
save hours in adjusting a planer to operate
properly.
Following are some problems that may arise
and their probable remedies. The Figure
illustrations are exaggerated for clarity. (Pages
19-21 also contain Troubleshooting remedies).
Washboard Finish
A very pronounced washboard finish down the
full length of the board results from one knife
being too high and forced to do all the cutting.
See Figure 20. Re-set
accordingly.
Clip Marks
If "clip" marks occur 6" (152mm) in from eac h
end of the board, the pressure bar is too high.
See Figure 21. Turn both right and left hand
adjusting screws (see Figure 15) the same
amount, 1/4 turn clockwise or less, and take
another 1/16" (1.59mm) deep cut. Re-examine
the board.
Continue the operate-adjust procedure until the
clip marks disappear. Should the board fail to
feed through, back off slightly on both adjusting
screws until feeding is
imperfections do not re-appear. Lock the
pressure bar adjusting screws with the jam nuts
