Stihl Troubleshooting

Check the spark plug to ensure it is not damaged or broken. Do this by removing the spark plug's rubber adapter before removing the spark plug itself with a wrench. Have a damaged spark plug removed straight away.

Clean the air filter with a damp rag and a toothbrush (for the hard-to-reach areas.) Remove as much debris from the air filter's screen as you can. Replace the filter if it is too dirty and/or damaged.

Inspect the gas tank. Remove the cap from the tank and look for any clogs or debris, which should be cleaned away. Check the fuel lines for cracks or holes where fuel might escape.
