Purchase gasoline in small quantities. Fresh gasoline
reduces chance of gum deposits forming and clogging
the fuel system and ensures a fuel blended for the
season. Do not use gasoline left over from the
previous season.
Do not add oil to the gasoline.
If a restriction of fuel occurs, replace the filter and
clean the vent in the fill cap.
IMPORTANT: Damage to fuel system components will
occur if gasoline containing alcohol is
used. Use only regular leaded or no-
lead gasoline, which does not contain
alcohol. Avoid using gas line de-icer
additives.
FUEL
Always use clean, fresh gasoline and a funnel with a
filter. Use regular no-lead gasoline with minimum
octane ratings as follows:
Research Method
90
Motor Method
82
Average 87
In the United States the average octane rating is
shown on gasoline pumps. In other countries, if the
method is not given, it is the Research Method. No-
lead fuel leaves less combustion chamber deposits.
Leaded gasoline may be used only if no-lead
gasoline is not available.
CAUTION:
Never store the
equipment with gasoline in the
tank inside a building where
fumes may reach an open flame
or spark. Allow the engine to cool
before storing in any enclosure.
CAUTION: Do not smoke when
working near fuel.
CAUTION: Handle gasoline with
care—it is highly flammable.
a. Use approved gasoline
container.
b. Never remove the cap of the
fuel tank or add gasoline to a
running or hot engine, or fill the
fuel tank indoors. Wipe up spilled
gasoline.
c. Open doors if the engine is run
in the garage—exhaust fumes are
dangerous. Do not run the engine
