Ok, so you're looking for help oiling the Shark Euro Pro? Ive got two pieces of useful information:
1 - Don't hesitate to contact Euro-Pro for advice.
They've got a customer support section of their site, with a live chat service - so take advantage of it. Not all companies go to such lengths to help out, trust me!
To use their live chat service, just go here: http://www.sharkclean.com/cgi-bin/livew/site.w?location=mcopy.w&mcopy=customerSupport&target=main&frames=no&sponsor=000006
2. Shark Euro pro model oiling instructions can be found on manuals online.
Ok, this method is going to need a bit of digging around (which is why I suggested the live chat first).
But if you want access to manuals, then here are a few sites that claim to have what you're looking for:
If any of these aren't what you expected, please come back and leave me a comment and I'll remove them from my answer!
