Procedure:
1. Assure pantograph is in resting position.
2. Loosen check nuts (2) at base frame and at upper frame.
3. Adjustment is done by turning the coupling rod tube (1):
Perform adjustment in ¼-turnings.
Turning CLOCKWISE
(SHORTEN coupling rod)
= Static contact force increases in the lower
working height / friction decreases
Extension [mm]
Static
Contact
Force [N]
Turning COUNTER-
CLOCKWISE
(LENGTHEN coupling rod)
= Static contact force decreases in the lower
working height / friction increases
Extension [mm]
Static
Contact
Force [N]
4. Checkup:
The upper frame has to rest on the Limit stops.
6. Fix check nuts (2).
5. Check trend of static contact force.
6. Check resting position ( Chapter #14.3).
7. Repeat adjustment if necessary. 
By changing the length of the coupling rod, geometry of the
pantograph has been modified.
Check trend of static contact force ( Chapter #14.10).
Adjust static contact force, if necessary ( Chapter #14.9).
