1. THREADING
A new sewer is apt to run the balance wheel in a reverse direction, thus rendering the
thread hitched in the shuttle race or breaking the thread, so it is necessary to practice idle
running. This is carried out as follows.
Loosen the stop motion screw (Fig. 1), so as to turn merely the balance wheel. Then place
both feet upon the treadle, with the left foot a bit ahead of the right, while keeping them
eight or nine cm apart from each other (Fig. 2). Turn the balance wheel towards you
continuously until it gathers speed and you can run the balance wheel on and on always
in the same direction. Thereafter you can tighten the stop motion screw and commence
sewing.

2. WINDING THE BOBBIN
Loosen the stop motion screw. Fix a reel of thread onto the spool pin on the machine bed.
After that pass the free end of thread through the tension disc (Fig. 3-1) and then pass it
through one of the holes of the bobbin. Press the bobbin onto the winder spindle, taking
care to see that the small pin in the spindle engages the notch in the right disc of the
bobbin. Then press down the winder-adjusting latch (Fig. 3-3), the bobbin winder latch
(Fig. 3-4) will drop at the same time upon the bobbin and the rubber pulley drops as well
and keeps in close with the hub of the balance wheel. After that with the tight hand turns
the balance wheel towards you and continues to turn the wheel with the assistance of
treading, the thread is thereby wound upon the bobbin. When it is fully wound, the
bobbin winder latch will skip off automatically. Take down the bobbin and retighten the
stop motion screw.
