6.4 Bobbin thread winding
- Insert the bobbin (1).
- Spool counter-clockwise manually onto the bobbin, mini-
mum six threads of the lower thread (3).
- Insert the thread ends into the equipment (4) and cut off the
ends.
- Press the lever (2) until it reaches its limit.
- Switch on the machine.
- The winder will automatically switch off after winding.
- Take off the hook bobbin and cut off the end in the equip-
ment (4).
- The nut (5) is instrumental to thread tension control for
winding. Turning clockwise sense the thread tension is in-
creased and the single threads are more firmly fixed on the
bobbin.
- The tension cannot be so extensive as far as slipping of the
winder friction drive has occured.
6.5 Needle replacement
Caution! Risk of injury!
Before remowing and inserting the needle turn
the main switch off and wait until the motor
stops!
- Turn with the hand wheel as far as the top needle (1) position
has been reached.
- Loosen the screw (2), (3) and remove the required needle.
- When inserting a new needle, care is to be taken that groove
(4) above the needles eye was in the same direction as the
hook.
- Tighten the screw (2), (3).
The inserted needle must respond to the sewing
category according to paragraph No. 5, table 3.
Otherwise it will cause damage to sewing, or even-
tually the machine could be broken.
6.6 Regulation of pressing the top roller
The pressing of the top roller should be as low as possible but
on a level so that the top roller would not fly over when needle
comes off the material and that the feeding power got over
the thread pull by stitch tightening.
By turning of the screw (1) clockwise pressing of the top roller
has been increased, by counter-clockwise turning pressing of
the top roller has been decreased.
