WARNING :
To prevent personal injuries caused by electric shock hazards or abrupt start of the sewing
machine, carry out the work after turning OFF the power switch and a lapse of 5 minutes or more.
To prevent accidents caused by unaccustomed work or electric shock, request the electric expert
or engineer of our dealers when adjusting the electrical components.
It is adaptable to the voltage of single phase 100V to 120V/3-phase 200V to 240V by changing the
voltage changeover connector mounted on FLT p.c.b.
(Caution) When the changing procedure is wrong, the control box will be broken. So, be very
careful.
Changing procedure of the changeover connector
1. Turn OFF the power source with the power
switch after conrming that the sewing machine
has stopped.
2. Draw out the power cord from the power plug
