If the Band Saw is to be hard-wired to a panel,
make sure a disconnect is available for the
operator. During hard-wiring of the Band Saw,
make sure the fuses have been removed or the
breakers have been tripped in the circuit to
which the Band Saw will be connected. Place a
warning placard on the fuse holder or circuit
breaker to prevent it being turned on while the
machine is being wired.
Converting from 230 Volt to 460 Volt
(Three Phase)
To convert from 230 volt to 460 volt:
1. In the band saw’s electrical box, change the
setting on the dial of the overload relay
(“FR” on page 42).
2. Rewire the connections to the transformer
(“T2” on page 42).
3. Change the leads in the junction box on the
band saw motor.
4. If using a plug, install a proper UL-listed
plug suitable for 460 volt operation.
IMPORTANT: Consult the diagrams on pages
40 and 41 for clarification of each of these
changes on 230V to 460V conversion.
Three-Phase Test Run
After wiring the band saw, you should check that
the wires have been connected properly.
Connect machine to the power source and turn
it on for an instant to watch the direction of blade
movement.
If the blade runs upward instead of downward,
disconnect machine from power, and switch
any two of the three leads in the motor junction
box (see “Electrical Connections”, page 40).

Blade Removal and Installation
Wear leather gloves when
removing or installing band saw blades. New
blades usually come in a coiled position; to
prevent injury, hold the blade with one hand
while carefully uncoiling it with the other.
1. Disconnect machine from power source.
2. Open the upper and lower doors, and swing
away the guard (Figure 5).
3. Remove the block from the front edge of the
table (Figure 5).
4. Loosen tension on the blade by turning the
tension handwheel (Figure 6) to the left.
