Is it poss to resolve this problem ( protection VS506P?

I have a VS506P Pro Action Shredder, attempted to use yesterday motor noise different from normal, & was struggling, never the less I proceeded to use it started with 2 A4 sheets stopped half way through second sheet,left it then it kicked back in after five,so on & forth for abt 20 mins then I gave up, have to say top of machine felt as though it had been running for 10mins,& would I be right in saying the motor was over heating & the safety kicked in ? The previous usage the machine was perfectly ok & there was no indication of any forthcoming issues, can u assist please.?
