The following will outline the basic operating principles of the NBA HOOPS™ basketball game. The ball gate uses micro
switches to determine positioning of the gate, which are activated by the cam on the ball gate shaft.
The gear motor uses a combination of hardware and software control to protect against over current damage. When an
over current condition is detected, the motor will shut off automatically. The game microprocessor will then decide wheth-
er or not the motor should be turned on. It will also determine at that time which way the motor should run.
Clean the surfaces of the cabinet and decals with a commercial cleaner such as 409™ or Fantastic™. Do NOT use
cleaners such as Wildcat pinball cleaner or alcohol. It can take the finish off of the decals. Use Pledge™ on all plastic
and painted surfaces. This product works especially well on clear plastics. Please note that other spray polishes do not
work as well.
The basketballs should be checked every week for proper inflation. A bicycle tire pump and inflating needle can be pur-
chased at any sporting goods store and most large discount stores. Keeping the balls properly inflated will make it more
difficult to pull them past the ball gate. It will also create more realistic basketball action when interacting with the hoop.
Any 8" basketball will work with this game.
NOTE: DO NOT OVER-INFLATE THE BASKETBALLS. THIS CAN CAUSE DAMAGE TO THE BALL AND SHORTEN
THE LIFE OF THE BALLS.
Remove AC power
•
Unfasten the (6) square drive screws and remove the ball gate housing, located on the right hand side of the ball
•
gate assembly.
Unbolt the control panel from the front of the game to gain access to the control panel.
•
•
Unplug the two mate-lock connectors (2 pin connector with the yellow/black and brown/white wires and the three pin
connector with the red, black and blue wires) located to the right of the transformer. Cut any tie-wraps holding the
harnessing.
•
Remove the two bolts that hold the ball gate bearing in place, located on the left hand side of the assembly. (Hint: a
long extension on a ratchet can be helpful for this operation.)
•
Pull the ball gate from the end by the bearing towards you. (the front of the game)
The gear motor can now be pulled away from the retaining bracket.
•
Remove the two Allen head set screws to remove the ball gate from the gear motor.
•
•
NOTE: When removing wires from the micro switches or motor, it is VERY important to make sure all wires are re-
turned to their proper terminals. Failure to do so will result in improper operation of the ball gate and could damage
the game. The wires are color coded so it will be easy to document where each wire goes.
•
IMPORTANT: Mark the position of the micro switch mounting bracket so that the switch actuators will line up correct-
ly with the cam on the ball gate when the unit is re-assembled.
•
Use thread locking compound on the Allen head set screws when re-assembling the ball gate to the gear motor.
Assemble in reverse order of disassembly. Tighten all hardware securely.
•
Re-test for proper operation
•
•
Temporarily shut off AC power, reconnect battery and turn AC power back on.
