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 StaBil™.
Starting the Engine
4. While holding the outer tube firmly
with left hand, use your other hand to
slowly pull the recoil starter handle
until resistance is felt, then pull quickly
to start the engine.
1. Slide the ignition switch to the “I” posi-
tion (engine ON).
2. Press the primer bulb until fuel can be
seen flowing in the transparent return
tube.
3. Set the choke lever to the CLOSED
position if engine is cold.
Make sure the cutting
attachment
is clear of
obstructions!
IMPORTANT!
Engine ignition is controlled by a two position switch mounted on the throttle housing labeled, "I" for ON or START and "O" for
OFF or STOP.

Filling the Fuel Tank
WARNING!
Minimize the risk of
re!
n STOP engine before refueling.
n ALWAYS allow the engine to cool
before refueling!
n Wipe all spilled fuel and move the
engine at least 10 feet (3 meters)
from the fueling point and source
before restarting!
n NEVER start or operate this
unit if there is a fuel leak.
ON
CAUTION!
This engine is designed to oper-
ate 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!
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. Never use any type of gasoline
containing more than 10% alcohol by
volume! Generic oils and some out-
board oils may not be intended for
use in high-performance C4 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 Mix all fuel with a 2-cycle
air-cooled mixing oil that meets
or exceeds ISO-L-EGD and/or JASO FC
classified oils at 50:1 gasoline/oil ratio.
Examples of 50:1 mixing quantities
n 1 gallon of gasoline to 2.6 oz. mixing oil
n 5 liters of gasoline to 100 ml. mixing oil
Oil is a registered JASO FC
classified oil and also meets or exceeds
ISO-L-EGD performance requirements.
Shindaiwa One is recommended for
use in all Shindaiwa low emissions en-
gines. Shindaiwa One also includes
a fuel stabilizer.
