Operating Controls
On/Off Switch (Sanding Drum)
To start the sander, pull
switch
(A, Fig. 17) out. To
stop the sander, push switch in. This switch
operates the sanding drum only. The conveyor is
controlled separately.
Switch Lockout
For safety and to prevent unauthorized use of the
sander, pull out the
key
(B, Fig. 17). Press
switch
(A, Fig. 17) to OFF position before removing the
key. When the key is removed, the drum cannot be
started.
Note:
The conveyor belt can still run when the key
is removed).
To replace the key, slide it back into the switch until
it snaps.
Conveyor
The conveyor speed is contolled by the conveyor
speed rate control knob
(E, Fig. 18) which sets the
conveyor speed from stopped (knob fully
counterclockwise) to 10fpm (knob fully clockwise).
Drum Height Control
Drum height is controlled by the
height adjustment
handwheel
. Rotating the handwheel counter-
clockwise lowers the drum; clockwise raises it.
One revolution of the handwheel moves the drum
approximately 1/16”.
Oscillator Switch
Referring to Figure 18:
The 22-44OSC sander can be operated as a
simple sander or as an oscillating sander.
When operating as a linear sander, the sander
drum rotates as the conveyor slides the workpiece
through. When in the oscillating mode, in addition
to the operation described, the sander drum head
oscillates from left to right as shown in Figure 18.
For linear
sanding mode:
1. Sander must be turned off.
2. Pull
the
oscillator switch
(A) OUT.
Note:
Before pulling the oscillator switch out for
linear sanding mode, turn the oscillator switch to
manually position the sanding drum to center or
where otherwise desired.
3. Turn
machine
on.

3. Turn the feed
rate control knob
(E) fully
clockwise.
Note:
The feed rate must be set to maximum
