Being a Butters agent think I should clear this 7 year warranty up, the warranty covers the transformer, choke and rectifier, your machine has to be serviced once a year by a butters service centre, I dont advise my web customers that there is a seven year warranty on butters machines, its not practical to send your machine in 7 times and pay 14 transport charges? and seven services? after all that you could buy a new machine
