FEED RATE
The infeed and outfeed rollers move the work-
piece through the planer while keeping it flat
and providing a consistent rate of movement.
The speed that these rollers move the work-
piece through the planer is known as the feed
rate.
Generally, low feed rates are used for dimen-
sioning passes, while higher feed rates are
used for finishing passes.
Figure 8 illustrates the three different positions
of the feed rate control knob:
• Push the knob in to
use the high feed rate
(30 FPM for Model
CE1115, and 20 FPM
for Model CE1120A).
• Pull the know out
to use the low feed
rate of
16 FPM.
• Move the knob to the center position to
place the gearbox in neutral.
IMPORTANT: Only change the feed rate
when the planer is running, but DO NOT at-
tempt to change the feed rate during any cut-

DEPTH OF CUT
The depth of cut on a planer means the
amount of material that is removed from the
top of the workpiece as it passes underneath
the cutterhead.
The depth of cut is set by adjusting the dis-
tance of the table below the cutterhead. This
distance is the thickness of the workpiece mi-
nus the depth of cut.
Although the correct depth of cut varies ac-
cording to wood hardness and workpiece
width, we recommend a maximum depth of
cut no more than 1⁄16". A series of light cuts
will give better end results and put less stress
on the planer than trying to take off too much
material in a single pass.
The planing depth of
cut is controlled by us-
ing the table height
handwheel on the
right side of the ma-
chine. Rotating the
handwheel (Fig. 9-A)
clockwise raises the
table.
The depth of cut is read directly from the inch/
millimeter scale on the front of the planer, as
shown in Figure 9-B.
One complete turn of the handwheel raises
or lowers the table approximately 1/16". The
range of material thickness that can be planed
is 3/16"–8".
BED ROLLER HEIGHT
Bed Roller Height Range 0.002"–0.020". The
correct height of the bed rollers will vary, de-
pending on the type of material you intend
to plane. However, as a general rule, keep the
bed roller height within 0.002"–0.020" above
the table surface, as illustrated in figure 10.
