Get your bench pin set up, get your blade installed properly. The teeth of the saw blade should be pointing down (in the photo I use a very large saw blade for you to see the details of the saw teeth). When you run your finger from the top to the bottom of the saw blade, it should be a relatively smooth stroke down.
Bonus tip, if you have room on your saw frame, you can write the size of the blade (in pencil) on the frame. This makes it really easy to remember what size of blade you are using. To lubricate your saw blade, run the blade through the lube.
