FUEL AND REFUELING

HANDLING THE FUEL SAFELY

WARNING:

Check for fuel leaks. If any are found, correct them before using the saw to prevent fire or burn injury.

nAlways handle fuel with care; it is highly flammable.

nAlways refuel outdoors and do not inhale fuel vapors.

nDo not let gasoline or oil come in contact with skin.

nKeep gasoline and oil away from the eyes. If gasoline or oil comes in contact with the eyes, wash them immediately with clean water. If irritation is still present, see a doctor immediately.

nClean up spilled fuel immediately.

Refer to Refueling in the Specific Safety Rules section of this manual for additional safety information.

MIXING THE FUEL

nThis product is powered by a 2-cycle engine and requires pre-mixing gasoline and 2-cycle oil. Pre-mix unleaded gasoline and 2-cycle engine oil in a clean container approved for gasoline.

nThis engine is certified to operate on unleaded gasoline intended for automotive use with an octane rating of 87 [(R + M) / 2] or higher.

■nDo not use any type of pre-mixed gasoline/oil from fuel service stations, this includes the pre-mixed gasoline/oil intended for use in mopeds, motorcycles, etc.

■nUse a high quality 2-cycle self-mixing oil for air-cooled engines. Do not use automotive oil or 2-cycle outboard oil.

■nMix 2% oil into the gasoline. This is a 50:1 ratio.

nMix the fuel thoroughly and each time before fueling.

■nMix in small quantities. Do not mix quantities larger than usable in a 30-day period. A 2-cycle oil containing a fuel stabilizer is recommended.

OXYGENATED FUELS

Some conventional gasolines are blended with alcohol or an ether compound. These gasolines are collectively referred to as oxygenated fuels. To meet clean air standards, some areas of the United States and Canada use oxygenated fuels to help reduce emissions.

If using an oxygenated fuel, make sure it is unleaded and meets the minimum octane rating requirements. Before using an oxygenated fuel, try to confirm the fuel’s contents. Some states/provinces require this information to be posted on the pump. The following are the EPA approved percentages of oxygenates:

Ethanol (ethyl or grain alcohol) 10% by volume. You may use gasoline containing up to 10% ethanol by volume. Gasoline containing ethanol may be marketed under the name “Gasohol.” Do not use E85 fuel.

MTBE (methyl tertiary butyl ether) 15% by volume. You may use gasoline containing up to 15% MTBE by volume.

Methanol (methyl or wood alcohol) 5% by volume. You may use gasoline containing up to 5% methanol by volume as long as it also contains cosolvents and corrosion inhibi- tors to protect the fuel system. Gasoline containing more than 5% methanol by volume may cause starting and/or performance problems. It may also damage metal, rubber, and plastic parts of the product or your fuel system.

If you notice any undesirable operating symptoms, try another service station or switch to another brand of gasoline.

NOTE: Fuel system damage or performance problems resulting from the use of an oxygenated fuel containing more than the percentages of oxygenates stated previously are not covered under warranty.
