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 first be treated with a
fuel stabilizer such as STA-BIL™.
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 resis-
tance is felt, then pull quickly to start the
engine.
2. Press the primer bulb until fuel can be
seen flowing in the transparent return
tube.
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.

IMPORTANT!
The primer system only pushes fuel through
the carburetor. Repeatedly pressing the
primer bulb will not flood the engine with fuel.
CAUTION!
Do not pull the recoil starter to the end
of the rope travel. Pulling the recoil
starter to the end of the rope travel can
damage the starter.
Mixing Fuel
1. Place the trimmer on a flat, level surface.
2. Clear any dirt or other debris from
around the fuel filler cap.
3. Remove the fuel cap, and fill the tank
with clean, fresh fuel.
4. Reinstall the fuel filler cap and tighten
firmly.
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!
Some types of gasoline contain alcohol
as an oxygenate. Oxygenated gaso-
line may cause increased operating
temperatures. Under certain condi-
tions, 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 outboard oils may not be intend-
ed for use in high-performance 2-cycle
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 engines and
also includes a fuel stabilizer.
1. Slide the ignition switch to the “ON”
position. See Figure 14.
3. Set the choke lever to the CLOSED
position if engine is cold.

there is a fuel leak.
n NEVER start or operate this unit if
the carburetor, fuel lines, fuel tank
and/or fuel tank cap are damaged.
