Press down and turn setting spindle A (figure E) with screw driver (5 mm)
in direction of arrow, thereby observe switch cam B. While a ratchet is felt
and heard, the switch cam B moves 90° every time. When switch cam B is
90° from the switch, continue turning slowly.
When the switch cam B snaps and trips the switch, stop turning and
release setting spindle.
If you override the tripping point inadvertedly (ratchet is heard after the
switch cam has snapped), continue turning the setting spindle in the same
direction and repeat the setting process.
