Maintenance
Care
of the
machine
To keep
your
sewing
machine
operating
satisfactorily
it requires,
like
other
precision
machines,
regular
clean
ing.
It need
not,
however,
be
lubricated.
The
stitchplate
should
occasionally
be removed.
Remove
the
presser
foot
and
lower
the feed
teeth.
There
is
a recess
in the
free
arm to
the right
above
the
hook
cover.
Push
the stitch
plate
straight
up
approx.
1
mm and
backward at the
same
time until
it
loosens.
Clean
be
tween
the
feed
teeth
with
the
brush
you
will
find
in
the
accessory
box.
When
replacing
the
stitch
plate,
insert
it from
behind
into
the
recess
in the
arm.
Ease
the front
edge
up
onto
the
small
pin and
continue
to
push
it forward
until
it
snaps
into
place.
Whenever
necessary
the bobbin
case and
hook
should
also
be brushed
clean.
Sizing
or finishing
compounds
from
fabric
may
adhere
to the
spindle
of the
hook.
If
this
has
happened,
the
spindle
should
also
be
cleaned
with
the
brush.
Remove
any pieces
of
thread
which
may
have
become
wound
around
the spindle.
Belts
Belt
adjustment
is not
required.
Changing
the
light
bulbs
The
machine
is
equipped
with
two
lights,
to
provide
the best
possible
lighting
and avoid
shadowing
from
the
presser
bar
and
needle
bar. They
are
located
on each
side
of
the needle
bar, as
illustrated.
In both
cases,
the
plastic
guard
can be
removed
by
inserting
the
small screwdriver
at the
rear
edge
of
the guard,
by
the arrows,
and
apply
ing
slight downward
leverage.
Do not
turn
the light,
just
pull
it
downward
and
fit in
a
new
one. The
plastic
guard
can
now
be
replaced
in the
recess.
Start
by
inserting
the
front
edge
and
press
it
into
the
holder.
Use light
bulbs
designed
for 12
V
and
maximum 5
W
as indicated
on
the light
guard.
