Instructions for Power Connection (Refer to Figure 1)
CAUTION ! Before connecting to the power supply, check the voltage supply switch setting located on the
side panel as shown in Figure 1.
To change from 110 volts service to 220 volt service simply slide the
switch fully to the top or to the bottom until “110V” or “220V” appears on the switch plate.
The acceptable range of input voltages for the “110 V” setting is between 110 V and 120 V @ 60 Hz and for
the “220 V” setting, between 220 V and 240 V @ 50 to 60 Hz. If you have any question regarding the input
voltage supply for your area, please ask your electric utility company.
To install the power cord, insert the female end of the power cord into the Power Cord Socket located on the side
panel and plug the male end into a grounded power outlet.
When using extension cords, use grounded heavy duty extension cords rated for 15 AMP service. To connect the
foot pedal switch, insert the 2 pin male connector located at the end of the foot pedal switch cord, into the two pin
receptacle located in the side panel. Tighten the connector with the sleeve nut located on the foot pedal switch
connector.
After checking to be certain that the machine is set for the correct input voltage, switch on the machine by
pressing the Lighted On-Off Power Switch on the side panel. At start-up, the LED will display a countdown from
“9.0” to “0.0” while the machine performs a self diagnostics check at start-up. The machine should be permitted
to warm-up for 10 minutes prior to stringing. After ten minutes, it is recommended that the “TEST” button be
pressed to self calibrate after warm-up.
