Here are the steps on how to mix fuel for a Stihl saw:
1. Determine the correct fuel mixture ratio for your saw. This information can be found in your saw's owner's manual.
2. Measure out the correct amount of gasoline and oil. Use a measuring cup or graduated cylinder to measure the liquids precisely.
3. Pour the oil into the gasoline.
4. Stir the mixture thoroughly until the oil and gasoline are completely mixed.
5. Label the fuel container with the fuel mixture ratio and the date it was mixed.
It is important to use fresh fuel in your Stihl saw. Old fuel can cause problems with starting and performance. It is also important to store fuel in a cool, dry place away from direct sunlight.
