Jet Tools VBS-3612 Adjustments, Converting from 230 Volt to 460 Volt Three Phase

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	Figure 5
tension handwheel (Figure 6) to the left.
