RAISING AND LOWERING ROLLERCASE
The rollercase contains the motor, cutterhead and dust
collection impeller. The depth-of-cut is controlled by raising
or lowering the rollercase.
To raise or lower the rollercase, rotate handle with knob.
One complete rotation of handle will raise or lower rollercase
by _/_" (see Figure 13).
A rotational direction label with depth indicator is located
under the handle.

Counterclockwise Down/Clockwise Up
FEED RATE ADJUSTMENT
Refer to Figure 14.
The planer has a 2-speed gearbox that feeds the work-
piece at 22 feet per minute (standard planing) and at
11 feet per minute (finish planing).
Finish planing a workpiece results in a better surface finish
than that obtained by planing at the higher speed.
The knob for adjusting the feed rate is located on the left
side of the top of the rollercase.
NOTE: Only change feed rate while the machine is running.
DEPTH-OF-CUT
GAUGE AND SCALE
Refer to Figure 14.
A depth-of-cut gauge is attached to the front of the rollercase.
The pointer on the depth-of-cut gauge accurately displays the
depth-of-cut per pass when workpiece is positioned below the
gauge. Cranking the handle moves the rollercase down and
the pointer shows depth-of-cut up to 3/32".

The Thickness scale with pointer allows easy adjustment of
roller case height. This scale indicates the finished size of the
workpiece in inches and millimeters. The side pointer can
be adjusted by loosening the pointer screws, re-positioning
pointer and retightening pointer screws.

PRESET GAUGE
Refer to Figure 15.
A six position workpiece thickness pre-set control knob is
mounted on the right side of the planer. This feature allows
quick production of identically sized workpieces. Six settings
are provided: %", W', _/2",3/4%1" and 1W'. See "Maintenance"
section to calibrate thickness preset gauge.

Example: Plane a 2" thick workpiece down to 1'/4".
°
Raise or lower rollercase until it is just above the
workpiece.
°
Position the workpiece on the planer table below the
rollercase.
°
Rotate knob until 1W' is indicated.
°
The planer is now set to stop the rollercase when the
workpiece thickness reaches 1W'.
NOTE: To reset for a different depth stop, raise the rollercase
by about 2 rotations. Turn knob to desired setup.
DIGITAL DISPLAY PANEL
Refer to Figure 16, page 8.
°
The digital display panel consists of two LCD displays
and four control buttons.
°
Display "A" shows the absolute height of the rollercase
over the table, which is also the finished workpiece
thickness.
°
Display "B" shows the depth of cut on the workpiece.
°
Button 'A' is used to calibrate display 'A'.
°
Button 'B' is used to reset display 'B' to zero (0).
°
Button 'C' toggles both displays A and B between inches
and millimeters.
°
Button 'D' turns power On and Off to display 'A' and 'B'.
