220V Conversion
To operate your mill with 220V power, you must: 1)
replace the 110V power ON/OFF switch with the
included 220V switch, 2) re-wire the motor, 3) re-
wire the transformer, and 4) install a NEMA 6-15
plug and receptacle.
Refer to Page 44 for the full 220V Conversion
Wiring Diagram.
You MUST disconnect the
mill from the power source
before beginning any of
the following 220V conver-
sion procedures to avoid
serious personal injury or
death by electrocution.
Replacing the Power Switch
Record the wire connections on the 110V switch
before you remove it, then replace it with the
included 220V power switch and make the same
wire connections.
