Fruit Machine Chat

Hi I have just bought this machine of ebay for kids to play on and am trying to locate a manual/booklet on it so I can work out how to alter the payout and do general maintenance. Please can any one help me locate one or suggest where I can buy one. Thank you for any help.

careful with your good intentions jil, even if there is only a very small chance that any of the kids develop a problem with gambling and machines it isn't worth it. i certainlty wouldn't dream of getting one for kids, but then i am one of those that has had machines dominate their life for decades! of course it is possible it could have the oppposite effect i suppose...
