Snap-on
presser foot
The
presser
foot No. 383,
which
accompanies
the
machine, is
applied for straight
seams,
zig-zag and
a lot
of other
utility seams. As you
can see,
it offers different
notches,
sewing
could be
done accordingly.
In case the
seam
should be
abt.
7 mm
in width
(l/4),
let the
material
run
at
the outer
edge
of presser foot,
for straight
seam.
The
next step
offers
a
seam
of 4 mm of
width
( 5 Lia),
and
the
step
inwards
a
seam
allowance
of
2
mm.
Changing
the snap-on
presser
foot
The presser
feet, which
accompany
the
machine,
have
the
form
of
loose
soles, which are
held in
place on the
presser foot
‘ankle’ by a
spring.
If
you
whish
to change
the presser
foot,
turn the
handwheel
towards
you,
until the needle
is in its
highest
position.
FRemove
the
presser
foot
by
drawing it
towards you,
while pressing
it
slightly downwards.
Slide the new presser
foot over
the
front
edge of the
ankle
bracket as shown in
the illustration.
There is
a
spring
on the
lower
end
of
the ankle
bracket. Slide
on
the
presser
foot
so
that the round
transverse pin on the
presser
foot fits into the
space
between
the bracket and
the
spring. Then press slightly
backward
and downward
and
the
presser
foot will snap into the
correct
position.
Sewing
foot
for zippers
The
sewing
foot
for
zippers
989
is
set
in quite the same
way
than the ordinary
sewing
foot.
The
construction
of
this
presser foot
renders
it
possible
by either inserting it right
or left
of
the
needle
to
sew
both sides
of
the zipper without
turning the material.
See
page 20.
Changing the
presser
foot
“ankle”
Certain
presser feet
cannot be
constructed
as
loose soles
and then
the ankle
bracket
must
also be changed.
Make
sure that the needle
is
in
its
highest
position. Then
loosen the retaining
screw
at the
left and
take off
the
presser foot.
