Feed Rate
Setting Feed Rate
Feed Rate ..............................................10–28 FPM
The infeed and outfeed rollers move the
workpiece through the planer while keeping it
flat and providing a consistent rate of movement.
The speed that these rollers move the workpiece
through the planer is the feed rate.
Generally, low feed rates are used for finishing
passes, while higher feed rates are used for
dimensioning passes.
Use the FEED SPEED control knob (see
Figure 26) to adjust the feed rate according
workpiece type and desired results.

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 distance
of the table below the cutterhead. This distance
is the thickness of the workpiece minus the depth
of cut. The planing depth of cut is controlled by
using the table height handwheel on the right
side of the machine. Rotating the handwheel
clockwise raises the table.
Although the correct depth of cut varies
according to wood hardness and workpiece width,
we recommend the maximum depth of cut (per
pass) be 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 depth of cut can be referenced directly from
the scale on the front of the planer, as shown in
the figure below.
Note:
The scale and digital readout function as a
general guide only, and is not intended for low-
tolerance, precision results. To ensure accuracy,
use a tape measure or caliper to measure your
workpiece thickness after each pass.
