9.2 Converting to 460 Volt
T
Voltage conversion must be done by a qualifi ed
electrican.
The Band Saw is prewired for 230 volt. To change to 460
volt operation, proceed as follows. Additional purchases
will be required: see electrical box parts list for any part
numbers to order.
1. Open main motor junction box cover, and change
leads based on wiring diagram inside cover. This
diagram is also shown in Figure 9-1. (Note: In case of
discrepancy, diagram inside junction box cover takes
precedence.) Reinstall cover.
2. Remove oil pump motor junction box cover, and
change incoming leads for oil pump, based on dia-
gram shown in Figure 9-2. Reinstall cover.
3. Remove coolant pump motor junction box cover, and
change incoming leads for coolant pump, based on
diagram shown in Figure 9-3. Reinstall cover.
4. Open the electrical box.
5. On the transformer, change the wire position from
230V to 460V
6. Replace main motor 230V overload relay with the
460V overload relay: Set dial to 7A.
7. Replace oil pump 230V overload relay with the 460V
overload relay: Set dial to 1.8A.
8. Replace coolant pump 230V overload relay with the
460V overload relay: Set dial to 0.35A.
9. On the primary fuse block, replace the two 2A fuses
with two 1A fuses.
10. Voltage conversion is now complete.
