Hi, I believe that I have a 4inch galvanised nail trapped underneath the drum of my Jetsystem Turbodry 1200 machine. The drum still rotates freely but I can hear the nail rattling about when the drum rotates. Will the nail damage the drum if I use the machine ? Can I remove the drum myself and if so is there a manual available online which provides instructions ? Alternatively, can you quote a price for an engineer to remove said nail ? Thank you.
