The Jonsered Little Red 220 chainsaw requires a 50:1 fuel mix ratio of gasoline to 2-cycle oil. This means that for every 50 parts of gasoline, you will need to add 1 part of 2-cycle oil.
Preparation:
1. Use fresh, unleaded gasoline with an octane rating of 89 or higher.
2. Use only high-quality 2-cycle oil specifically formulated for air-cooled, 2-stroke engines. Do not use automotive oil or outboard motor oil, as these can damage the engine.
3. Mix the fuel and oil thoroughly in a separate container before adding it to the chainsaw's fuel tank.
Fuel Mix Calculation:
To determine the amount of fuel and oil you need for a specific task, you can use the following formula:
Gasoline amount in gallons / Fuel mix ratio (50:1) = Oil amount in ounces
For example, if you want to mix 1 gallon of fuel:
1 gallon / 50 = 0.02 gallons of oil
0.02 gallons x 128 ounces/gallon = 2.56 ounces of oil
Therefore, you will need 1 gallon of gasoline and 2.56 ounces of 2-cycle oil to achieve a 50:1 fuel mix ratio.
Remember, always refer to the chainsaw owner's manual for the recommended fuel mix ratio and consult with a qualified mechanic if you have any doubts or concerns.
