Well after giving her a bit of a work out the other day I could smell hot dust coming from my HK3480, so there was only one thing to do...


Give her a quick blow out... And take a few photos at the same time.

Remember people, its always a good idea to unplug these things before removing the lid!!! (Unless your like me and like to listen to music while you work  :lol: )
