loaded with a lot of circuitry which
involves proper tim ing . Therefore,
bad contact will cause erratic opera-
tion . For instance , the bonus will take
longer to reset or will be improperly
scored . Most of the time , when the
motor cams are worn out , it will 'need
replacement. So , keep it lubricated
and properly adjusted for a lifetime
reliable operation .
NOTE : The dynamic brake of the
motor cams is made through a
formed blade located at position
#3 1 12 (see Figure 4) . Proper timing
requires the use of such device . Also
it prevents jarring and excessive wear
of the slot edges in the upper motor
cams.

Figure 6) and for reference switch
dog position is shown on chart of
Figure 7 .
Example : The switch dog actu-
ating the switch stack on position 11 2,
level C should be placed at the "L"
position . The n umber-letter combi-
nation is used by Gottlieb to
designate the number of switches
and their condition . For instance , 4A
means four switches normally open ,
IB one switch normally closed and C
stands for make-break switches .
The blades pressure applied to the
switch dog will determine the wear of
the cams . Some teeth or slots will
wear more than others , thus the
overall operation will not be uniform .
Usually the motor cam switches are

Physically , one must note , the
wires will jump from switch to switch
within the control motor harness ,
and be aware of the differences with
the other manufacturers , where the
wir€s will leave the score motor to the
relays.
The motor cams , actuate the
"switch dogs ," steel plates , move-
ables , that push the switch stacks and
are adjustable (factory only). The
bracket holding the switch dog has
two slots (5 and L, for Short and
