Leaded gasoline will destroy your products catalytic converter, causing it to no longer work properly. The manual says you can use eighty seven octane, but you should use at least eighty nine octane in order to prevent knocking, a condition caused by high engine temperature and increased bearing load, sometimes resulting in serious engine damage. For the best results, use husqvarna brands two stoke engine oil that is FDA certified.

    This oil is specially formulated for our air cooled two stoke engines. All Husqvarna products use a 50 to 1 mix, which means 2.6 ounces of oil are used to one gallon of gas. Husqvarna two stroke oil comes in convenient bottles that are easily added to one gallon of gas with no measuring required.Never use two stoke oil intended for water cooled engines, such as tcw3, sometimes referred to as outboard oil. When mixing, never attempt to mix the oil with the fuel in the gas tank on the unit. Always mix gasoline and oil in a clean container intended for fuel. Start by filling half the amount of gasoline to be used, then add the entire amount of two stoke oil. Shake the fuel mixture for at least ten to fifteen seconds. Add the remaining amount of gasoline and re-shake for an additional ten to fifteen seconds.

    Proper lubrication not only extends the life of your husqvarna product, but it also helps prevent the chain from breaking, which could result in serious or fatal injuries. Start by checking your chain oil. Chain oil must demonstrate good adhesion to the chain and also maintain its flow characteristics regardless of whether it is warm summer or cold winter weather. As a chainsaw manufacturer we have developed optimal chain oil. Use this oil in order to maximize chain life and minimize environmental damage. If our own chain oil isn't available, make sure you use an oil specifically designed for bar and chains. Never use waste oil, which can be dangerous to you, damage the oil pump in the machine and also harm the environment.

    All of our chainsaws have an automatic chain lubrication system, on some models the oil flow is also adjustable. The saw chain oil tank and the fuel tank are designed so that the fuel runs out before the chain oil. However, this safety feature requires that you use the right oil. If the oil is too thin, it will run out before the fuel.

Xpert Advisor Tips:If your Husqvarna product is equipped with a two stroke engine, it must always be run using a mixture of gasoline and two stroke oil. When mixing fuel, even small inaccuracies can drastically effect the ratio of the mixture. Never refuel the machine while the engine is running or is hot from recent use. Always make sure your fueling area has plenty of ventilation. After refueling, move the machine at least 10 feet from the refueling point before starting it. Never start the machine if you've spilled fuel on it. Wipe off spillage and allow remaining fuel to evaporate before use. Never start the machine if you have spilled fuel on yourself or your clothes.
