google/bing/search-engine-you-like will help you. Sorry, I don't know of any off the top of my head. It's all webpage or video tutorials (is there a reason why you prefer pdf over webpages?)
are you after something in particular?
if you're just starting off you should look at the tutorials that come with maya
that's a "Ch" pronounced as a "K"
Computer skills I should have:
Objective C, C#, Java, MEL. Python, C++, XML, JavaScript, XSLT, HTML, SQL, CSS, FXScript, Clips, SOAR, ActionScript, OpenGL, DirectX
Maya, XSI, Photoshop, AfterEffects, Motion, Illustrator, Flash, Swift3D
