    Feed dog (upper feed) (Fig. 10) The machine is equipped with a pyramid-teethed feed dog (4). Its movement in relation to the stitch plate can be adjusted after releasing screws (5). Or it can be replaced by saw-teethed feed dog. 3.5.1 Setting the feed dog A T T E N T I O N !

  • Page 24: Feed Plates

    Feed plates 3.6.1 Setting the feed plates A T T E N T I O N ! Switch off machine electrically! The feed plates should tilt easily and should sit close to the stitch plate. To guarantee a material feed free of twist, the pressure should be set to 12N on the left and to 6N on the right side, measured at the pivot of the feed plates.

  • Page 25: Plunger

    Plunger A T T E N T I O N ! Switch off machine electrically! 3.7.1 Replacing the plunger shafts (Fig. 11) Remove cloth support arm extension. Remove the rubber cover on the cloth support arm. Loosen the screw (7) and the attachment screw (1) at lever (2) and pull out the left plunger shaft (3).

  • Page 26: Setting The Plunger (Fig. 12)

    3.7.2 Setting the plunger (Fig. 12) Blind stitch settings for thick fabrics as shown in Fig. 12a and for thin fabrics as shown in Fig. 12b. The plungers are placed centrically in the stitch plate opening and 0.2 mm left from the needle shaft center (Fig.

  • Page 27: Setting The Cloth Support Arm (Fig. 11)

    3.7.3 Setting the cloth support arm (Fig. 11) Set the cloth support arm upwards by means of the stitch depth regulation until the needle is lifted by 0.2 mm by means of the left plunger in its upper cusp point. Use threaded pin (8) to limit the maximum height of the plunger and fixate with threaded pin (9).

  • Page 28: Thread Trimmer (Fig. 15)

    Thread trimmer (Fig. 15) The blade of the thread trimmer is activated by a rotary magnet, to which an electric release control system (microswitch) is connected. This prevents the machine from starting when the blade is no longer in its inital position. Thus the release control system prevents a possible collision between blade and looper.

  • Page 30: Adjustment (Fig. 15)

    3.8.2 Adjustment (Fig. 15) The thread trimmer drive must be inserted as far as it will go into the stitch plate clamp. Swivel the drive backwards so that there is a gap of about 1 mm between the drive and the sewing head. The blade of the knife has until about 2 - 3 mm from needle lever, stand forward, readjust if necessary.

  • Page 31: Replacing The Knife (Fig. 15)

    The machine should be positioned in such a way as the pedal is stepped back that the distance between looper and blade in cutting position is approx. 1 mm. For Strobel and EFKA controls, this corresponds to parameter 171, position P2E. MA_VEB200-2_A3_210511_en.doc...

    3.11 Positions Function Parameter Setting the reference position F-170 This function sets the reference position. Function Parameter Setting positions 1 and 2 F-171 This function sets the two positions. The AB611A control has two positions. The positions are set exclusively by programming the control.
  • Page 33 Machine with or without thread trimmer: Reference position: Turn hand wheel in the direction of the machine until the tip of the needle lines up with the right (inner) edge of the needle glide washers in the stitch-in direction. For that the right plunger needs to be up (Fig. 17). Fig.
  • Page 34 Notes for sewing drives which have two needle positions (i.e. sewing drive DC1210- AB611A (Fig. 19)): The above mentioned needle position is position 2 at the sewing drive. Position 1 must be set at the sewing drive in such a way, that the point of the needle (1) in the direction of stitch exit closes with the right (inner) edge of the needle slide plate.

  • Page 35: Setting The Positions

    3.12 Setting the positions 3.12.1 General notes The individual positions of the machine (machine positions) can be found in the operating manual of the sewing machine. N O T E ! For sewing machines that actually need only one position, both positions always need to be programmed anyway for the control programming.
