9. WIRING THE MACHINE HEAD

WARNING :

Junction cord preparation and wiring to the control box must be carried out by an electrical engineer

without exceptions. Be sure to turn off the power to the sewing machine and wait for five minutes before

starting the wiring work.

If the pin numbers of the connectors are not correctly connected, errors and breakage of parts and

control box can result. Carefully connect the machine-head connectors and the control-box connectors.
