4. Winding the bobbin
Place a spool of ttfread on pin 1 (Fig. 5) and pass the thread from left to right through
eyelet 2, clockwise around and between tension discs 3 and from the inside through
the slot in the bobbin. Wind a few turns of thread on the bobbin and place the latter on
spindle 4. Start the bobbin winder by pressing down lever 5. The bobom is wound
automatically while the machine is sewing. When a sufficient amount of thread has been
wound on the bobbin, a latch stops the bobbin winder.
The amount of thread to be wound on the bobbin is regulated by screw 6.
Turn this screw clockwise for more thread, or counter-clockwise lor less thread.
If the thread should pile up at one end of the bobbin, adjust the position of the bobbin
winder tension sideways, as may be required. To do this, loosen screw 7, adjust th.
tension and tighten the set screw again.
The tension on the thread is regulated by turning nut 8.
Maks sure the bobbin winder pulley rotates in the direction Indicated by an arrow in
Fig. 5.
