Turn the hand wheel in the direction of machine rotation until the symbol in the display goes out and Ref. Pos? appears in the display. The reference position is when the needle is in downward motion and the needle tip is at the end of the needle guide.

  • Page 53: Cutting Position (Fig. 23)

    For the VEB machines we set t 08 12 to the same value as t 08 13/cutting position. This allows us to disregard the key "Needle position after sewing stop"! For Strobel, the key "needle position after sewing stop" must be switched on as soon as t 08 12 has a different value than t 08 13!
