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.
 Always handle fuel with care; it is highly flammable.
 Always refuel outdoors and do not inhale fuel vapors.
 Do not let gasoline or oil come in contact with skin.
 Keep 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.
 Clean up spilled fuel immediately.
Refer to Refueling in the Specific Safety Rules section of
this manual for additional safety information.
MIXING THE FUEL
 This 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.
 This engine is certified to operate on unleaded gasoline
intended for automotive use with an octane rating of 87
[(R + M) / 2] or higher.
 Do 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.
 Use a high quality 2-cycle self-mixing oil for air-cooled
engines. Do not use automotive oil or 2-cycle outboard
oil.
 Mix 2% oil into the gasoline. This is a 50:1 ratio.

Mix the fuel thoroughly and each time before fueling.
 Mix 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.
