WARNING!
Minimize the Risk of Fire!
n ALWAYS stop the engine and allow it
to cool before refueling. Avoid overll-
ing and wipe off any fuel that may have
spilled.
n Wipe all spilled fuel and move the
engine at least 3 meters from the fueling
point and source before restarting!
IMPORTANT!
Mix only enough fuel for your immediate
needs! If fuel must be stored longer than
30 days and oil with fuel stabilizer
is not used, it should rst be treated with
a fuel stabilizer such as STA-BIL™.
Mixing Fuel
CAUTION!
This engine is designed to operate on
a 50:1 mixture consisting of unleaded
gasoline and ISO-L-EGD or JASO FC
class 2-cycle mixing oil only. Use of
non-approved mixing oils can lead to
excessive carbon deposits.
CAUTION!
n Some types of gasoline contain al-
cohol as an oxygenate. Oxygenated
gasoline may cause increased op-
erating temperatures. Under certain
conditions, alcohol-based gasoline
may also reduce the lubricating
qualities of some 2-cycle mixing oils.
n Never use any type of gasoline
containing more than 10% alcohol
by volume! Generic oils and some
outboard oils may not be intended
for use in high-performance 2-cycle
type engines, and should never be
used in your Shindaiwa engine.
n Use only fresh, clean unleaded gasoline
with a pump octane of 87 or higher.
n Mixed with 50:1 Shindaiwa ISO-L-EGD
or JASO FC class 2-cycle mixing oil at
a gasoline/ratio of 50:1. Shindaiwa One
meets or exceeds these requirements.
Oil is a registered JASO FC classi-
fied oil and also meets or exceeds ISO-L-EGD
performance requirements.Shindaiwa One is
recommended for use in all Shindaiwa low emis-
sions engines. Shindaiwa One also includes a
fuel stabilizer.
