DCC300 belt threading

sorry for the basic question but I just replaced the drive belt on my 300 and now my transport is running at around 10x the speed it should. It looks simple to thread the belt but perhaps it is threaded in a not so obvious way. Is is straightforward - or can someone point me to a drawing of it please

Hope this helps.

Please be gentle. This is my first attempt at drawing with a pen on my laptop screen.
