REFUELING
This engine is certified to operate on unleaded gasoline with a pump
octane rating of 86 or higher.
We recommend refueling after each use to minimize the air present in
the fuel tank.
Refuel in a well-ventilated area with the engine stopped. If the engine
has been running, allow it to cool first. Never refuel the engine inside a
building where gasoline fumes may reach flames or sparks.
You may use regular unleaded gasoline containing no more than 10%
ethanol (E10) or 5% methanol by volume. In addition, methanol must
contain cosolvents and corrosion inhibitors. Use of fuels with content
of ethanol or methanol greater than shown above may cause starting
and/or performance problems. It may also damage metal, rubber, and
plastic parts of the fuel system. In addition, ethanol is hygroscopic,
which means it attracts and retains water in the fuel system. Engine
damage or performance problems that result from using a fuel with
percentages of ethanol or methanol greater than shown above are not
covered by warranty.
If your equipment will be used on an infrequent or intermittent basis
(more than 4 weeks before next use), refer to the Fuel section of the
STORAGE chapter (page15) for additional information regarding fuel
deterioration.
Never use stale or contaminated gasoline or an oil/gasoline mixture.
Avoid getting dirt or water in the fuel tank.
To refuel, remove the fuel tank
cap, and fill the tank with
gasoline to the shoulder of the
filler neck. Refuel carefully to
avoid spilling fuel. Do not
overfill.
After refueling, tighten the fuel
tank cap securely.
Move the pump at least 10 feet
(3 meters) away from the
fueling source and site before
starting the engine.
NOTICE
Fuel can damage paint and plastic. Be careful not to spill fuel when
filling your fuel tank. Damage caused by spilled fuel is not covered by
the DISTRIBUTOR’S LIMITED WARRANTY (page21).

Fuel Storage Container

Store your gasoline in a clean, plastic, sealed container approved for
fuel storage. Close the vent (if equipped) when not in use, and store
the container away from direct sunlight. If it will take more than 3
months to use the fuel in the container, we suggest adding a fuel
stabilizer to the fuel when you fill the container.
If you have some fuel left in your storage container at the end of the
season, the Environmental Protection Agency (EPA) recommends
adding the gasoline to your vehicle's gas tank
(http://epa.gov/reg5oair/mobile/winter.html).
