1 About this additional instructions
This additional instructions describes upgrade kit 0911 597774 Stitch
position optimization for class 911-210.
Background
Multi-directional stitching paths lead to difficulties with unreeling
directions. This may result in the hook thread forming a festoon stitch i.e.
double plaiting of the needle thread.
To prevent this festoon stitch occurring, stitch position optimization can be
activated so the hook thread is guided to the left of the stitch hole. This will
result in the needle always making the stitch to the right of the hook thread,
thereby avoiding a festoon stitch.

4. Secure the pneumatic hoses (2) with the cables ties to the existing
cables and hoses and guide them forwards to the hook.
3.2 Attaching stitch position optimization
Figure 4: Stitch position optimization
The path of the hook thread slide (2) is restricted by two eccentric (1)
screws. The eccentric screws can be adjusted while installed.
ATTENTION
Laying the hoses incorrectly may result in damage
The pneumatic hoses may become damaged if they come into contact
with the rotating shafts or moving parts.
Fix the pneumatic hoses so they are secure.
Cut off any protruding part of the cable tie.

1. Loosen the screws of the retainer (4).
2. Remove the retainer (4) with the throat plate (3) and needle guide (4).
3. Dismantle the throat plate (3) and needle guide (5) from the retainer (4).
4. Attach the throat plate (3) and needle guide (5) to the stitch position
optimization (6).
5. Insert stitch position optimization (6) into the machine.
6. Check the throat plate and needle guide setting ( see Service manual).
The hook thread pusher should be located as close as possible to the
underside of the throat plate without touching it.
7. Tighten the stitch plate optimization screws (6).
8. When opening out the upper section of the machine, ensure that stitch
position optimization does not collide with the oil tray. Bend the oil tray
forwards slightly if necessary.
Operation

4 Operation
4.1 Checking stitch position optimization
1. On the control panel, using the Service > Multitest > Test outputs
function, activate the magnet valve at output 7.
The hook thread pusher's path to the center of the stich hole is
restricted by the two eccentric screws so that the hook thread is
diverted to the left over the center of the stitch hole.

4.2 Programming stitch position optimization
Stitch position optimization is controlled by means of technology points in
the seam program e g. in DA-CAD:
• Output 7 = ON: Stitch position optimization activated:
• Output 7 = OFF: Stitch position optimization deactivated:
Figure 6: Programming stitch position optimization
Alternatively, stitch position optimization can be switched on and off via
contour adjustment on the control panel.
