and chips act as an abrasive to the playfield surface and can cause premature wear of
the finish. When the balls in your game develop a “hazy” or “foggy” look, or when you
can’t clearly see your reflection in the ball’s finish, they should be replaced.
Rubber rings and light bulbs should be replaced as required – when rings show signs of
wearing out and when light bulbs periodically burn out.
e) Changing Playfield Lamps:
To change the playfield lamps, you must raise the playfield. See section 7(b) ’Raising the
Playfield.’ Now you have complete access to most of the playfield lamps. See discussion
below.
To remove a bulb, turn the lamp counter-clockwise and pull out. Then pull the bulb out.

f) Game Adjustments:
Mechanical assemblies on the playfield may require some maintenance and adjustment
from time to time. While many assemblies have been reengineered to not require
adjustment, the targets and the slingshots may still require adjustment. If you have a
slingshot or target that is not responding well, or appears “sluggish” or “over sensitive”,
you may need to make a slight adjustment to the leaf-switch used on the device to adjust
its sensitivity.
If you’re uncomfortable making adjustments on your game, we can refer you to a
independent serviceman in your area.
DO NOT apply any lubrication to any of the mechanical devices on the playfield (flippers,
bumpers, etc.) These devices are designed to “run dry”, and any added lubricant, while
possibly providing a temporary solution, will soon cause the unit to “gum up” and cause
more problems. Adding lubricant to devices may also pose a fire hazard. Any lubrication
added to the game will void the game’s warranty.
g) Leaf Switch Adjustment:
There are 7 targets on the playfield, 3 round and 4 rectangular. These targets utilize
mechanical leaf switches. There are also 2 slingshots with similar switches. With constant
use these switches tend to lose their adjustments. It is necessary readjust them. This will
become evident when a target does not score properly. See the discussion below on
