HOW TO USE THE PEDAL
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). 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 without pressing the pedal with heel).
After the needle and looper threads are cut with the
needle stopped at the top of its stroke, the looper
thread is held by the clamp spring and the needle
thread is moved up to the presser foot by the air wiper.
Keep on pressing the pedal with heel to raise the presser foot.
Then remove the fabric. If you want to raise the presser foot while the machine stops,
press the pedal with heel (position C).

ADJUSTING THE THREAD TRIMMER
6-1 Position of the movable knife
Adjust movable knife A so that the bottom of movable
knife base D is flush with that of movable knife A.
Adjustment is made by loosening two screws C.
The point of the movable knife should be 0.6mm to the
left of the center of the needle hole.
With the movable knife retracted, front E of the needle
plate support bracket should be almost aligned with
front F of the movable knife base.
6-2 Position of the stationary knife
With the movable knife fully retracted, there should be
a overlap of 0.3mm between stationary knife G and the
movable knife. Adjustment is made by loosening
screw H.
< Note >
If the gauge width is large, the overlap of the stationary
knife and the right m vable knife should be equal to that
of the stationary knife and the left movable knife.
o
To achieve this adjustment, check to see if the stationary
knife is placed in a horizontal position.
