WARNING!
When filling the fuel tank, make
sure the engine is stopped and
cool.
Filling the fuel tank or mixing
fuel and oil must be done in a
place where there is no risk of
fire.
CAUTION!
Some gasolines contain alcohol as
an oxygenate! Oxygenated fuels
may cause increased operating
temperatures. Under certain condi-
tions, alcohol-based fuels may also
reduce the lubricating qualities of
some mixing oils. Never use any
fuel containing more than 10% al-
cohol by volume! Generic oils and
some outboard motor oils may not
be intended for use in high-perfor-
mance air-cooled 2-cycle engines
and should never be used in your
Shindaiwa engine.
CAUTION!
This engine is designed to oper-
ate on a 50:1 mixture consisting of
unleaded gasoline and premium
2-cycle mixing oil only.

5 liters gasoline to 100ml mixing oil.
IMPORTANT!
Mix only enough fuel for your imme-
diate needs. If fuel must be stored
longer than 30 days and oil with fuel
stabilizer is not used, it should first be
treated with a fuel stabilizer such as
StaBil™.
