Today, we're going to change the Spark Plug on a Stihl MS180 Chainsaw. First of all use a flathead screwdriver to unlock the shroud. You can now remove the shroud from the machine. Lift the air filter from the machine, this will make it easier to access the spark plug. Remove the rubber cap from the spark plug. Use the 19mm Hex Socket Spanner to loosen the Spark Plug. Once it's loose you can remove the spark plug by hand. By hand, screw the new spark plug into the machine. Make sure it's secure. Place the spark plug cover back on. Relocate the air filter back into place. Place the shroud back over the machine. Fix the shroud onto the machine by tightening the screw located at the back of the shroud.
