TROUBLESHOOTING AND REPAIR
GEARBOX IS DIFFICULT TO TURN
1. A gearbox–coupling collar may have been forced
against a gearbox causing uneven or difficult
turning. The usual cause for this is a handle grip
coming off a rod and allowing the gearbox to hit
either another gearbox or a cabinet end. To
repair, simply loosen the collar and back it away
from the gearbox between 1/32” and 1/16”.
Retighten.
2. Gear teeth being stripped out will generally cause
binding at certain points of rotation. This situation
should not occur until many games have been
played. However, to check for bad gears, first
remove the gearbox from the game. Loosen the
gearbox collar and slide out the gearbox. If teeth
on gears are worn out, replace the gearbox.
3. A worn gear bearing can cause a gearbox to work
improperly. If you suspect a gear problem, first
remove the gearbox from the game. If no
problems are visible, disassemble the gearbox. If
a worn bearing is found, replace the gearbox.
GAME LIGHTING DIM
1. The scoreboard bulb may be burned out. Open
the dome and see if the bulb appears to be burned
out while the game is plugged in. Unplug the
game. Remove the screws holding the right
diffuser in place. Replace the light bulb and
reassemble.
2. Very low AC power will cause poor lighting. To
test, use a voltmeter on the suspect line to
determine voltage. A CHEXX" game hooked up to
a line with too many other games may experience
this difficulty. Move the game to its own AC line if
this problem is experienced.
NO LIGHT IN GAME
1. The light bulb may be burned out. Open dome
see if bulb is burned out. Replace if necessary.
2. A loose scoreboard connector is not likely to affect
the bulb without affecting some other component
in the scoreboard. However, make sure the
connectors are firmly seated.
PLAYERS RUN INTO THE END OF THEIR SLOTS
1. A rod collar slipping may cause a player to hit the
end of a slot in an ice surface. Open the game
and rotate the rod until you can see the rod and
gearbox touch, through the slot in the collar. If the
rod and the gearbox do not touch, loosen the
collar make sure the rod and gear box coupler
touch, and retighten the gearbox. Be sure to
leave 1/32” to 1/16” between the collar and the
gearbox body.
SCORE INDICATORS DO NOT WORK PROPERLY
1. A bad LED may cause malfunction. Replace the
scoreboard and run electronic tests on the faulty
unit.
2. A bad scoreboard chip may cause indicator
malfunction. Replace the scoreboard and run
electronic tests on the faulty unit.
3. A loose connection may cause malfunction.
Check and repair as necessary.
GAME LOSES PLAY SEQUENCE. GIVES FALSE
SCORE, WILL NOT START WHEN MONEY IS
INSERTED
1. Although game is protected against static
electricity, an unusually large shock will cause the
microprocessor to lose sequence. To correct the
problem, turn off power and turn it back on to
reset electronics.
2. A game plugged into an ungrounded outlet has no
protection from static electricity. A large enough
shock may destroy the IC chips. Electronic tests
may be run to determine the fault. Repair as
necessary .
