Setting.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 distance of
the cutterhead above the table. This distance is the
thickness of the workpiece minus the depth of cut. The
planing depth of cut is controlled by using the cutterhead
elevation handwheel (see
Figure
14
) on the right side of
the machine. Rotating the handwheel counterclockwise
raises the headstock.
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 scale functions as a general guide only,
and is not intended for low-tolerance, precision results.
A small amount of backlash may be present with the
cutterhead elevation handwheel after switching height
directions. Switching height direction may cause slightly
less than
1
⁄
16
" backlash during the first handwheel turn.
As the handwheel is turned more rotations in the same
direction, backlash will not be a factor.

Elevation.Scale
The elevation scale (see
Figure.15
) on the righthand
side panel at the front of the machine shows workpiece
thickness after it leaves the planer. The thickness
measurement is indicated by the red line.
Note:
The cutterhead elevation scale does not provide
a precise measurement and should only be used for
approximate measurements. If precise workpiece
thicknesses are needed, use calipers to ensure your
workpieces meet your standards.
