7.3 Adjust predominance
Carry out test step only on variants 250 and
254.
The exact adjustement can be done by inser-
tion or removing of compensation washers.
Use washers with the following composition:
Material: Steel
Surface protection: gal Zn 6 c yellow
–
Adjust exact pressure with the cap (see fig. 8).
Clockwise rotation: pressure increase
Counter-clockwise rotation: pressure de-
crease
