Warning:
Make sure that the sewing mahine is switched
off and the plug has been pulled out of the
socket when threading in order to avoid injury
if the sewing machine should be accidentally
switched on.
a) Threading the lower bobbin
To load the lower bobbin with thread:
• Pull out one of the two thread spool carriers
i
on top and place a spool of thread there.
• You can place a felt pad underneath the
spool of thread , so that the bobbin runs
evenly.
• Place an empty spool on the winder
spindle
o
.
• Pull the thread through the upper thread
guide
t
.
• Wind the loose end of the thread clockwise
a few times around the empty spool .
• When the first windings of thread are taut
against the spool, press the spool with the
winder spindle
o
against the spool stop
a
.
• Pull the handwheel
s
on the right of the
machine slightly outward in order to discon-
nect the sewing mechanism from the motor.
• Now switch the sewing machine on and step
on the foot switch . Once the spool is full,
cut the thread.
• Press the winder spindle
o
back to the left
and remove the full spool.
• Do not forget to push the handwheel
s
back
in – otherwise the sewing mechanism remains
disconnected from the motor.
