Setting Belt Tracking
! WARNING
Setting belt tracking may require operator to
have machine hooked to electrical and air
power while having doors open. Use
extreme caution! Failure to comply may
cause serious injury!
The tracking has been set at the factory and
should not need adjusting. If you are
experiencing a tracking problem follow the steps
listed below.
The abrasive belt must track between the two
limit switches (A, Figure 12). The machine
functions will stop if the belt activates one of the
limit switches.
The air pressure should be approximately 80
psi, see “Connecting to Air,” page 7.
1. Start by turning both valves (B, Figure 13)
clockwise to close completely. This will turn
off the oscillation.
2. Loosen belt tension and position sanding
belt in the center of the idle roller.
3. Turn the sander main power switch to the
“ON” position. Jog the main motor by
pressing the spindle “ON” button quickly
followed by the spindle “OFF” button.
4. Once you have determined which way the
belt is drifting loosen the two hex nuts (C,
Fig. 13).
5. If belt is running too far to the left (viewed
from back of sander) rotate the top of the
turnbuckle (D, Figure 13) toward the user.
6. If belt is running to far to the right (viewed
from back of sander) adjust the top of the
turnbuckle (D, Figure 13) away from the
user.
7. Once the belt is tracking approximately in
the center of the idle roller press the spindle
“OFF” button.
8. Hold the turnbuckle in place while tightening
the lock nuts.
9. Press the spindle “ON” button and recheck
the tracking.
11

Setting Belt Oscillation
! WARNING
Setting belt oscillation may require operator
to have machine hooked to electrical and air
power while having doors open. Use
extreme caution! Failure to comply may
cause serious injury!
Now that the belt is tracking properly it is time to
set the oscillation. Follow the steps listed below.
1. Start by opening both valves (A, Figure 14)
approximately a 1/4 turn.
2. If the belt is oscillating too quickly, close
each valve by approximately 1/16 turn. If
the belt is oscillating too slowly, open each
valve by approximately 1/16 turn.
3. Once the belt is oscillating with the correct
speed (about one complete cycle every
second), lock the valves in place with the
lock rings (B, Figure 14).
Digital Controller
A. This LED readout displays the current
thickness setting of the machine.
B. The digital thickness controls are capable of
operating and displaying in either inches, or
millimeters.
C. This LED readout displays the value input by
the operator on the keypad.
D. Four function buttons are available to the
user: SET, STOP/CLEAR, UNITS, and
RUN. The use of these buttons is detailed
in the following sections.
E. The keypad is used to input set values (the
operator’s desired thickness setting). The
up and down arrows can be used to move
the table up or down without keying in an
exact numerical thickness value.
F. This indicator light will illuminate a steady
yellow when the table is moving up or down.
This light will blink if there is an error of any
sort.

Changing Units of Measure 5. If sander does not sand the top of your
board, raise the table 0.01" and re-run the
board.
1. Press “SET” button (A, Figure 16) once, and
two changes will occur. First the present
value will change to "uuuu". Second the
“SET” button indicator light will illuminate.
6. Repeat Step 5 until the wide belt sander
lightly sands the entire top surface of your
calibrating board.
2. Now press “UNIT” button (B, Figure 16)
once. The present value should now read
inches, and the "Inches" indicator light
should be illuminated.
7. Measure the thickness of the board using a
pair of calipers.
8. Enter the measured thickness value from
Step 7 on the keypad. The value keyed in
will be displayed as the SV (Set Value).
Note: To change back to millimeters from
inches follow the same procedure – press
the “SET” button then “UNIT” button.
9. Press the SET button. The PV readout will
now display "uuuu". Also, the SET indicator
light will be illuminated.
Sanding to a Specific Thickness
1. Key in the desired thickness setting on the
keypad. The desired thickness setting will
be displayed as the set value.
10. Press the SET button again.
11. The PV and SV readouts should now both
display the measured thickness of your
calibrating board.
2. Press the “RUN” button (C, Figure 16). This
will cause the table to move up, or down
until the set value is achieved.
3. While the table is moving you will notice that
the run indicator light will be illuminated.
Note: do not feed material through the
sander while the conveyor is raising or
lowering.
Calibrating the PV (Present Value)
The controller should be recalibrated in a variety
of circumstances: whenever the platen height is
adjusted, changing brands or grits of abrasive
belt, setting up the machine for the first time, or
the operator feels that the machine is not
sanding to exactly the proper thickness.
The following sections will describe the use of a
calibrating board. The calibrating board should
be made of a hardwood.
1. With the sanding belt and feed belt turned
“OFF”, place your calibrating board on the
feed belt and slide it into the machine.
2. Use the “UP” button (D, Figure 16) to raise
the table so that the pressure rollers are
about 1/32" above the calibrating board, see
Figure 17.
3. Remove calibrating board from sander and
turn the feed belt and abrasive belt “ON”.
13
4. Use the “UP” button to raise the table 0.02",
as indicated by PV (Present Value) and run
the calibrating board through the sander.

Thickness Scale
After setting the present value using the
calibration board adjust the pointer (A, Figure
18) so that it matches the present value.
Conveyor Tracking
1. Remove the guard (B, Figure 18).
2. Turn on the conveyor and adjust to the
highest speed.
3. If conveyor drifts to the left rotate tracking
bolt (C, Figure 19) clockwise a 1/2 turn. The
adjustments are not noticeable right away
due to the slow speed the conveyor travels.
4. If conveyor drifts to the right rotate tracking
bolt (D, Figure 19) clockwise a 1/2 turn. The
adjustments are not noticeable right away
due to the slow speed the conveyor travels.
5. Replace the guard after adjustments are
complete and the conveyor is tracking
properly.
