Seriously, check this out.
First you find a radical by the number of strokes (presumably you know how to write it), this gives you a page and column number.
You open that page, locate radical, and under it look for the kanji you need. This gives you an 音読み reading… which is not what you need in many cases! (Unless you look up compound word)
Then search through the book to find the kanji by 音読み reading to identify the 訓読み reading!
Finally you find the word you need and a definition!
