6. If the conveyor table moves in the wrong
direction, turn off the machine and
disconnect from power
. Switch any two of
the three incoming power leads at R,S,T.
7. Re-connect power to the sander.
460 Volt Conversion
To convert the sander to 460V:
1. Disconnect sander from power source.
2. In the electrical cabinet, switch the “R” wire
on the transformer from the 220V to the
440V terminal. See Figure 6. (Refer to the
wiring diagram on the inside cover of the
electrical box for clarification.)
3. Replace two 230V overload relays with two
460V overload relays (not included; see
parts list for stock numbers).
4. Change the wiring at the main motor, the
conveyor table motor, and the table
elevating motor, according to the wiring
diagrams inside their respective junction
boxes.
5. If using a plug, install a UL/CSA-listed plug
appropriate for 460V operation.
Extension cords
The use of an extension cord for this sander is
discouraged, because of the machine’s high
amperage draw. If an extension cord becomes
necessary, make sure the cord rating is suitable
for the amperage listed on the machine’s motor
plate. An undersized cord will cause a drop in
line voltage resulting in loss of power and
overheating.
Adjustments
Sanding Belt Tracking and Oscillation
The sanding belt should oscillate left and right
without a tendency to slide off the rollers. If the
sanding belt runs outside of the normal track, it
will contact a limit switch and the machine will
stop automatically.
The oscillation settings have been made at the
factory, but should be checked by the operator.
NOTE: When a new sanding belt is installed,
there may be a slight length tolerance between
the right and left sides of the sanding belt which
may result in incorrect tracking. If this occurs,
the oscillation timing can be set to compensate.
1. Adjust oscillation while the machine is
running.Turn on the air valve switch and
press the sanding belt start button (see
Figure 19).
