Maintenance
Саге 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 stitch plate 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.

from fabric may adhere to the spindle of the hook. If this
has happened, the spindle should also be cleaned with
the brush. Remove anv nieces of thread which mav have

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.
