OPERATION
Mixing Fuel/Filling With Fuel
WARNING!
Minimize the risk of fire burns and
personal injury!
IMPORTANT!
Shindaiwa high-performance 2-cycle
engines are designed to operate on a
50:1 mixture of unleaded gasoline
and 2-cycle engine oil. Using a fuel
mixture less than 50:1 ratio (such as
80:1 or 100:1) can cause cata-
strophic engine failure!
■ STOP engine before refueling.
■ ALWAYS allow the engine to
cool before refueling!
■ ALWAYS open the fuel cap
slowly to allow any pressure
build-up in the tank to release
fuel vapor slowly.
■ Wipe all spilled fuel and move
the engine at least 10 feet (3
meters) from the fueling point
and source before restarting!
■ NEVER start or operate this
unit if there is a fuel leak.
■ NEVER start or operate this
unit if the carburetor, fuel lines,
fuel tank and/or fuel tank cap
are damaged.
■ NEVER smoke or light any
fires near the engine or fuel
source!
■ NEVER place any flammable
material near the engine
muffler!
■ NEVER operate the engine
without the muffler and spark
arrester in good working condition.
CAUTION!
Ⅵ Some types of gasoline contain
alcohol. Never use any type of
gasoline containing more than
10% alcohol by volume! More
than 10% alcohol by volume
may affect the lubricating
qualities of 2-cycle engine oils
reducing engine life and/or
causing engine failure.
Ⅵ Generic engine oil and marine
engine oil may not be intended
for use in high-performance 2-
cycle engines and should never
be used in Shindaiwa engines.
Engine oils not intended for use
high-performance air-cooled 2-
cycle engines can cause
excessive carbon deposits,
reduce engine life and/or cause
engine failure.
1. Use only fresh, clean unleaded
gasoline with a pump octane rating
of 87 or higher.
2. Mix fuel with a 2-cycle engine oil
designed for use in high-perfor-
mance 2-cycle air-cooled engines.
NOTE:
Shindaiwa offers two performance
levels of 2-cycle air-cooled engine oils,
Shindaiwa 2-Cycle Engine Oil and
Shindaiwa ONE High Performance 2-
Cycle Engine Oil. Shindaiwa 2-Cycle
Engine Oil is designed to meet the
lubrication demands of most 2-cycle
air-cooled engines. Shindaiwa ONE
High Performance 2-Cycle Engine Oil
is recommended when superior
lubrication is needed to help protect
engines used in severe operating
conditions. Shindaiwa ONE also
contains a fuel stabilizer to help
maintain fuel quality when fuel is
stored longer than 30 days.
