Initially adjust unit on the pedestal so that armature
fingers do not touch the yolk in the rest position,
(viewed from top of switch between cover and frame).
This can be done by loosening the mounting screw in
the molded pedestal and moving the unit in the
downward position.
Target Manually raise the armature and check to
see that the target drops when the gap between the
armature and the core residual pin is not less than
1/64. The cover may be removed and the tab hold-
ing the target reformed slightly if necessary. How-
ever, care should be exercised so that the target will
not drop with a slight jar.
Pickup The unit should pickup at 98% rating and
not pickup at 85% of rating. If necessary, the cover
leaf springs may be adjusted. To lower the pickup
current use a tweezer or similar tool and squeeze
each leaf spring approximate equal by applying the
tweezer between the leaf spring and the front surface
of the cover at the bottom of the lower window.
If the pickup is low, the front cover must be removed
and the leaf spring bent outward equally.
