4.8 Sewing material transport
The machine transports the sewing material using a rigid upper transport. The
feed (stitch length) can be adjusted between 5
–
8 mm in 4 levels. The standard
version of the machine is equipped with a sawtooth transporter.
4.8.1 Adjusting the stitch length
CAUTION!
Switch off the machine and depress the motor switch
pedal to ensure that the machine is truly at a standstill.
Press the stitch setting knob
((1) figure 2) and turn the handwheel until it simply
snaps into place. The configured stitch length corresponds to the number
engraved in the handwheel as it comes to a standstill in the highest position.
Press down the setting knob and move the handwheel forwards until the
desired stitch length noticeably snaps into place.
4.8.2 Adjusting the upper transporter
The transporter can be adjusted in its intrusion depth to the needle plate by
loosening the two fastening screws. If the stitch length is adjusted across
a greater range e.g., from 8 to 5, then the transporter should be readjusted.
Adjustments might also be required when changing to sewing materials that are
thicker or otherwise different in quality.
Here, observe the instructions given in the mechanic's manual.
