Power Connection
Electrocution or fire may occur if machine is ungrounded, incorrectly connected to power, or connected to an undersized circuit. Use a qualified electrician to ensure a safe power connection.
Once your machine is set up and assembled as previously described in this manual, it is ready to be connected to the power source.
Use the information in this section to determine the power source requirements needed to operate this machine. If your existing power source does not meet the stated requirements, consult with a qualified electrician about running a new circuit.
Note About Extension Cords: Using an incorrectly sized extension cord may decrease the life of electrical components on your machine.
Note About
220V Conversion for SB1021
Wiring diagrams are provided on Pages 44 and 46 in this manual, showing the Model SB1021 wired for both 110V and 220V. Refer to these diagrams when following this procedure.
To convert the Model SB1021 to operate on 220V:
1.DISCONNECT BANDSAW FROM POWER!
2.Rewire the motor for 220V, as shown in the diagram on the inside of the motor junction box. If there is not a diagram in the junction box, use the motor wiring diagram in this manual (see Page 46).
3.Locate the power transformer in the electrical panel (see Page 48, Figure 50) and remove the wire attached to the 110V terminal and connect it to the 220V terminal.
4.Turn the dial on the overload relay (see Page 48, Figure 50) from 14A for 110V to 7A for 220V.
5.Locate the welding transformer in the control panel (see Page 48, Figure 49). Remove the wire connected to the #2 terminal and move it to the #5 terminal; remove the wire connected to the #4 terminal and move it to the #7 terminal.
6.The machine is now wired for 220V.
