14. PERIODIC INSPECTION
The items listed below require periodic check and maintenance to retain the performance of this
machine and to ensure safe business operation.
When handling the Control Unit (Gun), the player will be in direct contact with it. In order to
always allow the player to enjoy the game, be sure to clean it regularly. Also, it is advisable to
provide wet tissue, etc. available for player use.
● Be sure to check once a year to see if power cords are damaged, the
plug is securely inserted, dust is accumulated between the socket
outlet and the power plug, etc. Using the product with dust as is
accumulated can cause fire and electric shock hazards.
● Never use a water jet, etc. to clean inside and outside the cabinet. If
wetness occurs for any reason, do not use the product until it has
completely dried.
● Periodically once a year, request the place of contact herein stated or
the distributor, etc. where the product was purchased from, as regards
the internal cleaning. Using the product with dust as is accumulated in
the interior without cleaning can cause a fire or accident. Note that
cleaning the interior parts can be performed on a pay-basis.
