Adjusting the prox-
imity switch holder

Carry out the following steps:

Screw the adjusting screw (6) into the proximity switch holder down to the upper
edge of the balancer (7).

By slightly slackening the countersunk screw, position the proximity switch holder in
the slot in the lantern so that the point of the adjusting screw (6) rests on the
shoulder of the balancer in the direction of the actuator (A).

Fix the proximity switch holder in position with the countersunk screw (3).
