HOW TO USE THE THREAD TRIMMER
■
Pressing the pedal with toe (position A) starts the
machine.
Releasing the pedal (position B) stops the needle at the
top/bottom of its stroke (adjustable with the motor).
■
If the needle stops at the bottom of its stroke as adjusted,
pressing the pedal with heel (position C) raises the needle.
As soon as the needle stops at the top of its stroke by
pressing the pedal with heel, the thread trimmer gets
actuated (if the needle stops at the top of its stroke as
adjusted, the thread trimmer gets actuated by pressing
the pedal with heel).
■
Returning the pedal to position B lowers the presser foot.
■
The presser foot can be raised or lowered freely by releasing the pedal (position B) or
pressing the pedal with heel (position C) until the pedal is placed at position A for the
next sewing operation after the threads are cut.
