First, go to Stihl website and request a free manual.
Then basically, remove the two cover nuts, slacken the chain adjuster, remove chain and bar. Remove the single nut in the center of the clutch/brake assembly. Comes apart easily.

I can answer this question...
how do I replace the clutch on a Stihl wood boss 028 av I bought in 1986?
