Honda HS521 Owner's Manual page 12

Gasoline is extremely flammable and is explosive under certain
conditions.
Refuel in a well-ventilated area with the engine stopped. Do not smoke
or allow flames or sparks in the area where the engine is refueled or
where gasoline is stored.
Do not overfill the fuel tank (there should be no fuel in the filler neck).
After refueling, make sure the tank cap is closed properly and securely.
Be careful not to spill fuel when refueling. Spilled fuel or fuel vapor may
ignite. If any fuel is spilled, make sure the area is dry before starting the
engine.
Avoid repeated or prolonged contact with skin or breathing of vapor.
KEEP OUT OF REACH OF CHILDREN.
m Don't let snow get in the fuel tank. Water in the fuel system can
cause stalling and difficult starting.
FUEL TANK CAPACITY: 1.25 e (0.33 US gal, 0.27 Imp gal)

GASOLINES CONTAINING ALCOHOL
If you decide to use a gasoline containing alcohol (gasohol), be sure it's oc-
tane rating is at least as high as that recommended by Honda. There are
two types of "gasohol":
one containing ethanol, and the other containing
methanol. Do not use gasohol that contains more than 10% ethanol. Do
not use gasoline containing methanol (methyl or wood alcohol) that does
not also contain cosolvents and corrosion inhibitors for methanol. Never
use gasoline containing more than 5% methanol, even if it has cosolvents
and corrosion inhibitors.
NOTE:
l
Fuel system damage or engine performance problems resulting from the
use of fuels that contain alcohol is not covered under the warranty.
Honda cannot endorse the use of fuels containing methanol since
evidence of their suitability is as yet incomplete.
l
Before buying fuel from an unfamiliar station, try to find out if the fuel
contains alcohol, if it does, confirm the type and percentage of alcohol
used. If you notice any undesirable operating symptoms while using a
gasoline that contains alcohol, or one that you think contains alcohol,
switch to a gasoline that you know does not contain alcohol.
