not light up after having turned ON the power
switch, immediately turn OFF the power switch
and check the supply voltage. In addition, in
such a case as this, re-turn ON the power
switch when 2 to 3 minutes or more have
passed after turning OFF the power switch.
2) When the needle bar is not in UP position, it
automatically turns to the UP position.
When turning ON the power, the needle bar moves.
Do not put your hands or things under the needle.

3) The pedal is operated in the following four steps:
a. The machine runs at low sewing speed when you
❷
lightly depress the front part of the pedal. ❷
b.
The machine runs at high sewing speed when
you further depress the front part of the pedal. ❷
(If the automatic reverse feed stitching has been
preset, the machine runs at high speed after it
completes reverse feed stitching.)
c. The machine stops (with its needle up or down) when you reset the pedal to its original position.
d. The machine trims threads when you fully depress the back part of the pedal. ❹
* When the auto-lifer (AK device) is used, one more operating switch is provided between the sewing ma-
chine stop switch and thread trimming switch. The presser foot goes up when you lightly depress the back
part of the pedal ❸, and if you further depress the back part ❹, the thread trimmer is actuated.
When starting sewing from the state that the presser foot has been lifted with the Auto-lifter and you depress the back part of the pedal, the presser foot only comes down.
