Setting steps
1. Position the upper stitch length adjusting wheel (2) > 3.
2. Switch machine to short stitch length.
 The key for the stitch length (1) does not light up. 
If the key lights up, press key (1) again.
WARNING
Risk of injury
The lower stitch length adjusting wheel has to be 
set when the machine is switched on, because 
a switchover is automatically made to the upper 
adjusting wheel when the machine is switched off.
Carry out all work with extreme caution.
