How exactly do you use it? I feel stupid asking, but I'm not at all sure... can someone tell me in full detail, please?

That being said......
First take the clutch cover off
Second remove the set screw that keeps the star nut from turning, may need a little help with a tool such as a DULL screwdriver and a hammer. I use a old blunt screwdriver and a leather mallet.
Thirdly, disengage the clutch and lock it disengaged with the pin on the clutch handle.
Fourth, remove the star nut by turning counter clockwise.
Finally take the tool, remove the threaded puller bolt and thread the tool into the center threads in the clutch, followed by reinserting the threaded bolt and while holding the tool with a wrench, tighten the threaded puller bolt.
Should slide off easy, and keep in mind there is a key waiting to fall out.

By the way, as you can see I didn't break the clutch apart...there are 50+ ball bearings in it.
