HOW TO THREAD THE TOP THREAD (fig1)
-Lift up the presser foot lever and lift the needle by turning the
balance wheel following the arrow indicated on the same. Follow
the following instructions:
1.- Lift the bobbin pin and put it in place (n).
2.- Pull the thread through guide 3 (o).
3.- Lead the thread through the tension disc (q).
4.- Pull the thread through guide 4 (s).
5.- Lead the thread through the hole in the bar to tighten (r).
6.- Lead the thread through guides 1 (a) and 2 (c).
7.- Lead the thread through the eye of the needle (d) from front
to back.
PUTTING THE LOWER BOBBIN IN PLACE
1.- With your left hand, hold the end of the thread leaving about
8 cm outside.
2.- Pull the threader downwards by the central plate groove
(fig2). Lead the thread between the wires of the threader and
pull to take the thread out by the groove.
3.- Put the bobbin in place. The thread has to be lead clockwise.
4.- Leave out about 10 cm of thread on the top part of the bobbin
towards the presser foot.
5.- Cover the bobbin with its lid.
HOW TO START SEWING
1.- Lift the needle by turning the balance wheel clockwise. Lift up
the presser foot.
2.- Make sure that the two ends of the thread are placed needle
backwards at least 10 cm.
3.- Put the garment in place, hold it down with the presser foot
and lower the needle manually.
4.- Press the pedal or press the O/I button until I position and
start sewing. Slide the garment with your hand. Do it slowly for
the first few stitches. If, while sewing, by using either the pedal
or through the On button, you need to modify the sewing speed,
press the speed control button: I position, normal speed and II
position, faster speed.
5.- To stop sewing, either stop pressing the pedal or place the on
button in O position.
IMPORTANT:
When finishing, lift up the needle manually, and in this way it will
not bend when taking the garment out; lift up the presser foot
and withdraw the garment. Then cut both threads at 10 cm. in
length.
HOW TO ADJUST THE THREAD TENSION
-Revise if the lower thread and the top one have the same tension
and if this tension is strong enough to close both threads in the
centre.
-If the top thread is too tight, the bobbin thread will be in the top
part of the garment. For this, slacken the needle thread tension.
-If the top thread is too loose, the needle thread will be on the
lower part of the garment. To correct this, tighten the thread.
WINDING THE LOWER BOBBIN
1.- Slide back the lid and extract the empty bobbin.
2.- Adjust the rewinding spindle in the hole for the winding of the
bobbin (l). Turn counter-clockwise.
3.- Lift up the foldable spindle (p) and insert a thread bobbin.
