Bringing the upper blade into a rest position
To make certain types of seam, or to more easily operate the adjust-
ment wheel for cutting width f, you must bring the upper blade i into
a rest position.
For this, press the upper blade i to the right and rotate it a little, so
that it is firmly seated (Fig. 2 and 3).
Needle Information
This machine uses standard commercial flat-shaft needles for sewing machines.
These prevent the incorrect insertion of the needle. You can purchase these
needles in any specialist shop.
You can use needles of the sizes 11 and 14 in this machine.
The adjoining table gives you a brief overview of the differences when using a
needle (for detailed information, see "Setting the seam width).
Upper looper element
For some kinds of stitches you will need to use the upper looper element.
When you need to insert it is described in the individual stitches.
Insert the small wire from behind in the eyelet of the upper looper o and
the plastic bolt, on the other end and from the front, in the hole in the upper
looper o (Fig. 4a).
You can store the upper looper ready for use in the slot behind the front
