14 35 37 36 39 II ig. 8 For winding the cover 14 is turned upwards and the lever 34 carrying the winding device is swivelled out towards backside onto the stop (fig. 8). A more perfect stitch is obtained if the under thread is chosen somewhat finer than the one used for upper thread. The reel from which the winding has to be done is placed onto one of the two reel-pins 35. In order to prevent the whole machine from running needlessly when winding, turn with your right hand the handwheel release screw 16 as far as possible towards you, at the same time holding the handwheel 34 15 firmly with your left hand. Place the bobbin 37 onto the bobbin shaft 36 pro- jecting from the hinged cover. The threading is done 15 as follows: First lead the thread from the reel to the winder pretension device 34, and from here around thread guide bolt 38 to the bobbin 37. The thread should wind in clockwise direction. Now push 16 lever 39 towards the bobbin until it gets engaged. Then the motor can be started by a slight pressure on the knee lever, respectively on the pedal starter, the mechanism being still at rest. Operate the machine until the bobbin is filled, whereupon the winder will stop automatically. When the filled bobbin has been taken off, lever 34 with winder pretension device has to be turned in and hinged cover 34 can be returned to its starting position. Tighten handwheel release screw 16 again. 13

For
winding
the
cover
14
is
turned
upwards
and
the
lever
34
carrying
the
winding
device
is
swivelled
out
towards
backside
onto
the
stop
(fig.
8).
A
more
perfect
stitch
is
obtained
if
the
under
thread
is
chosen
somewhat
finer
than
the
one
used
for
upper
thread.
The
reel
from
which
the
winding
has
to
be
done
is
placed
onto
one
of
the
two
reel
-pins
35.
In
order
to
prevent
the
whole
machine
from
running
needlessly
when
winding,
turn
with
your
right
hand
the
handwheel
release
screw
16
as
far
as
possible
towards
you,
at
the
same
time
holding
the
handwheel
15
firmly
with
your
left
hand.
Place
the
bobbin
37
onto
the
bobbin
shaft
36
pro-
jecting
from
the
hinged
cover.
The
threading
is
done
as
follows:
First
lead
the
thread
from
the
reel
to
the
winder
pretension
device
34,
and
from
here
around
thread
guide
bolt
38
to
the
bobbin
37.
The
thread
should
wind
in
clockwise
direction.
Now
push
lever
39
towards
the
bobbin
until
it
gets
engaged.
Then
the
motor
can
be
started
by
a
slight
pressure
on
the
knee
lever,
respectively
on
the
pedal
starter,
the
mechanism
being
still
at
rest.
Operate
the
ma-
chine
until
the
bobbin
is
filled,
whereupon
the
winder
will
stop
automatically.
When
the
filled
bobbin
has
been
taken
off,
lever
34
with
winder
pretension
de-
vice
has
to
be
turned
in
and
hinged
cover
34
can
be
returned
to
its
starting
position.
Tighten
handwheel
release
screw
16
again.
