5 Operating the machine
The machine is operated with an electronic-pneumatic control. The operation is
very easy:
5.1 Right hand treadle
By means of the right hand treadle the motor is operated, the front cup is
opened and the needle is positioned.
The process is as follows:
- Usually the front cup is opened.
- Insert the material.
- Step the treadle to the front, the front cup is closed.
- Step the treadle further down, the machine sews the quicker the more the
treadle is stepped down.
- Heel the treadle, the machine stops, the needle is in its first position (i.e.
approx. 12 mm in front of the feed cup). (See also point “5.2 Operating the
gathering device (EV)”– “5.2.2 Gathering (left hand treadle)”)
- Heel the treadle further, the needle moves into its second position, i.e. its
point stops approx. 7 mm within the feed cup, the front cup is opened.
5.2 Operating the gathering device (EV)
If the pneumatic gathering device is needed to gather extra fullness, e.g. at the
toe part, stop the sewing process at the previously determined point - as
described in point “5.1 Right hand treadle” the needle is now in the material and
keeps it in this position (Fig. 14).

Keep insole and upper apart in a way that the gathering device can swivel down
between the two parts.
