Machine Adjustment
Caution
▶ Always turn off the power when mounting a needle.
▶ If the operator mistakenly steps on the pedal while the power is on, the machine will start
automatically and can result in physical injuries.
▶ When using clutch motor, be aware that the motor will continue to rotate for a while even
after the power is switched off due to inertia. Start to work on the sewing machine only
after the motor has come to a complete stop.
