Figure 5. Adjustments and Lubrication Points, Shooter Lane Feeder.
•
Because of the functional design (arm-actuated via solenoid plunger operation), the pivot points of the
Left and Right Kickers ("Slingshots") aU require lubrication as a regular servicing procedure.
Mechanical adjustments are simple and somewhat similar to the Shooter Lane Feeder. These
mechanisms should also be checked for proper fit (snugly tight) where they attach to the playlield.
Lubrication to ensure proper operation also applies to the target blades of the two 3-Bank Drop
Targets. Regular maintenance is essential to a game's continuing contribution to the operator's
earnings.
