Test Run After Wiring
On the three-phase unit, after wiring has been
completed, you should check that the wires are
connected properly:
1. Connect machine to power source and
press the start button (A, Figure 8).
2. The sanding belt should move left to right,
as viewed from the front of the machine. If
the sanding belt movement is incorrect,
press the stop button (B, Figure 8) and
disconnect machine from power.
3. Switch any two of the three wires at "R,S,T".
4. Reconnect machine to power source.
Converting to 460 Volt
Refer to the diagrams on pages 31 and 32 for
connecting the motor leads for 460 volt power.
Also convert to a 460V switch. If using a plug, it
must be a proper UL/CSA listed 460 volt plug.
The edge sander must comply with all local and
national codes after being wired.
If hard-wiring directly to a control panel, follow
the same safety recommendations mentioned
under “230 Volt Operation.”
Extension cords
An extension cord is not recommended for this
machine, but if one is 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.
Use the chart in Figure 9 as a general guide in
choosing the correct size cord. If in doubt, use
the next heavier gauge. The smaller the gauge
number, the heavier the cord.
Adjustments
Main Table Positioning
The main table can be raised or lowered to suit
your workpiece, and is designed on a special
balance mount so that smooth adjustment is
achieved by a simple push or pull on the table.
To adjust, loosen the locking handles (A, Figure
10) and move the table to desired position by
hand, then tighten locking handles (A, Figure
10).
If the table is in low position,
it may spring up suddenly when the locking
handles are loosened.
