in order to prevent excessive rod
wear (Figure 5). Restretch the spring ,
check the plunger and stop .
Remember that the plunger
should be clean and completely free
of oils, a frequent cause of "sticking ."
Reassemble the unit. Make sure that
the round part of the coil spool is
down . Hold the unit firmly , pressing
the coil-link assembly and tighten the
two phillips screws; then reassemble
the un it with the playfield , and align
and lubricate the skirt stem to the
switch cup (Figure 6) . Mount the coil
bracket to the playfield . Check the

Little maintenance is required for
these units . Check the switch
adjustment and the direction the ball
is kicked out. Bend with a pair of
long nose pliers accordingly , to make
sure that the ball is shot in the proper
direction . The tension on the spring
mechanism will damage the playfield
sooner . Retighten the screws,
especiaHy the ones that hold the unit
to the playboard .

Adjust the ball shooter alignment.
Replace the rubber tip if necessary .
Rubber chipping, sluggish action ,
and jumping balls are common
causes of shooter misalignment;
rubbers in general are severly hit by
the balls in the new games . Because
of this , playfield clean-up is needed
much earlier than before .
Use a wide soft bristle brush to
wipe the excess dirt and big rubber
particles off the playfield through the
outhole . Remove all plastic for
cleaning and to give you access to
the rubbers and bulbs . A rubber
shaped by its standing position has
lost most of its flexibility and should
be replaced . Others can be cleaned
with a commercial rubber cleaner.
Rotate the clean ones to prevent
wear. Use a round . soft bristle brush
