The switching differential is changed by
turning the grub screw (2) inside the
setting screw (1). The switching point is
not changed by adjusting the differential,
only the reset point is shifted by the
amount of the differential. One 360°-
rotation of the differential screw varies the
switching differential by approx. 25 % of
the total differential range.
