Honda HS621 Bedienungsanleitung Seite 23

Gasoline spoils very quickly depending on factors such as light
exposure, temperature and time.
In worst cases, gasoline can be contaminated within 30 days.
Using contaminated gasoline can seriously damage the engine
(clogged carburetor, stuck valve).
Such damage due to spoiled fuel is disallowed from coverage by the
warranty.
To avoid this please strictly follow these recommendations:
Only use specified gasoline (see page
Use fresh and clean gasoline.
To slow deterioration, keep gasoline in a certified fuel container.
If long storage (more than 30 days) is foreseen, drain fuel tank and
carburetor (see page
GASOLINES CONTAINING ALCOHOL
If you decide to use a gasoline containing alcohol (gasohol), be sure its
octane 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.
Fuel system damage or engine performance problems resulting
from the use of gasoline that contains alcohol is not covered under
the warranty. Honda cannot endorse the use of gasoline containing
methanol since evidence of its suitability is as yet incomplete.
Before buying gasoline from an unfamiliar station, first determine if
the gasoline contains alcohol, if it does, find out 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.
