 Turn on the machine at the main switch and wait for it to be ready for operation.
 Press the presser foot key and raise the presser foot.
 Place the cut-to-size trouser piece under the raised presser foot directly in front of the
needle (attenuated "skip stitch" photo cell).

at a fi xed speed (set in P08) and possibly with the skip stitch system switched on until
the start cut is made ("Tape cutter" photo cell and the clearance programmed in P01).
 Switch on the skip stitch system after reaching the appropriate clearance (P02).
 After cutting the tape, sew with treadle control until the "Skip stitch" photo cell light up
again and the skip stitch system switches on after reaching the clearance in P03.
 Once the "Tape cutter" photo cell lights up, the machine continues to sew at a fi xed
speed (P08) until the fi nal cut clearance (P04) is reached and the fi nal cut is made.
 Now stop the machine with the needle down and raise the presser foot.
 The next piece can be sewn once the treadle is in the neutral position.
