End backtacks
● If this key is pressed, the backtacks at the end of the seam (end backtacks) are switched
on or off. The number of reverse stitches (C) or forward stitches (D) can be changed by
pressing the +/- key underneath. To convert from double backtack to single backtack set
the corresponding number of stitches at zero.
Needle position
● If this key is pressed the corresponding function is switched on or off. When the function
is switched on, the needle positions at t.d.c. after sewing stops.
Foot position after stop
● If this key is pressed the corresponding function is switched on or off. When the function
is switched on, the presser foot is raised after sewing stops.
Foot position after trimming
● If this key is pressed the corresponding function is switched on or off. When the function
is switched on, the presser foot is raised after thread trimming.
Thread trimmer
● If this key is pressed the thread trimming function is switched on or off.
Speed (only in programmed sewing)
● If this key is pressed the corresponding function is switched on or off. In the seam
program the speed is not dependent on the pedal. When the function is switched on, the
speed cannot be adjusted by pedal. Sewing can only be carried out at the set maximum
speed.
● If the function is switched off, the speed up to maximum speed is adjusted by the pedal.
Reverse sewing
● If this key is pressed the corresponding function is switched on or off. When the function
is switched during programmed sewing, the corresponding seam section is sewn in
reverse.
Manual seam (only in programmed sewing)
● If this key is pressed the machine switches to manual sewing. When the function is
switched on, the move to the next seam section is not carried out by stitch counting or
sensor, but manually with the use of the pedal (position "-2").
Stop
● If this key is pressed the corresponding function is switched on or off. When the function
is switched on, the machine stops automatically at the end of a seam section.
Sensor
● In manual sewing the number of compensating stitches from the point where the
photocell is light to the end of the seam can be set under parameter 111, and in
programmed sewing directly.
