Threading the Top Throad Fig. 8
The thread spool is placed on one of the two pins 22 placed at rear of top arm. From
there pass thread through the rear eyelet 8, through front eyelet 8 down to the thread
tension between the tension discs in the tension box 31, up to the take-up lever 7 and
down again behind the thread guide pin 32 and through the needle thread guide 33 and
finally through the needle eye from front to rear. Make sure that take-up lever 7 and
needle are in the raised positions when threading the machine. Thread tension

is
formed as a double tension. When only one thread is inserted, it is immaterial whether
the thread is passed between the front or rear tension disc.
Bringing up the Bobbin Thread
The end of the top thread projecting from
the needle eye is loosely held between
thumb and index finger of the left hand,
while the fly wheel is turned towards the
operator by une revolution with the right
hand, until the take-up lever is approxi¬
mately in its extreme upper position. The
upper thread end is now slightly pulled,
which causes the bobbin thread to conic
up. Top and bottom threads are slightly
tightened and placed rearwardly under
the presser foot.
