REFUELING
Honda recommends using a No-Spill

gas can, which meets the
demanding requirements of the California Air Resources Board
(
).
This engine is certified to operate on unleaded gasoline with a pump
octane rating of 86 or higher.
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. 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,
please refer to the fuel section of the
STORAGE
chapter (
) 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 snowthrower at least 10 feet (3 meters) away from the
fueling source and site before starting the engine.
