How do you change plug in stihl 024 AV chainsaw?

To change the spark plug on a Stihl 024 AV chainsaw, first ensure the engine is cool and disconnect the spark plug wire. Use a spark plug wrench to remove the old plug by turning it counterclockwise. Install the new spark plug by hand to avoid cross-threading, then tighten it with the wrench until snug, but avoid over-tightening. Finally, reconnect the spark plug wire, and your chainsaw is ready to use.
