Mixing Fuel
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
intended for use in high-performance
C4 engines, and should never be used
in your Shindaiwa engine.
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.
Starting the Engine
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.

Use only fresh, clean unleaded gasoline
with a pump octane of 87 or higher.
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
1 gallon of gasoline to 2.6 oz. mixing oil
5 liters of gasoline to 100 ml. mixing oil
Mix only enough fuel for your immediate
needs! If fuel must be stored longer than
30 days and
not used, it should first be treated with a
fuel stabilizer such
as STA-BIL™.
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.

The primer system only pushes fuel
through the carburetor. Repeatedly
pressing the primer bulb will not flood the
engine with fuel.

Filling the Fuel Tank
WARNING!
Minimize the Risk of Fire
NEVER smoke or light fires near the
engine.
ALWAYS stop the engine and allow
it to cool before refueling. Avoid
overfilling and wipe off any fuel that
may have spilled.
ALWAYS inspect the unit for fuel leaks
before each use. During each refill,
check that no fuel leaks from around
the fuel cap and/or fuel tank. If fuel
leaks are evident, stop using the unit
immediately. Fuel leaks must be re-
paired before using the unit.
ALWAYS move the unit at least 10 feet
(3 meters) away from a fuel storage
area or other readily flammable materi-
als before starting the engine.
NEVER place flammable material close
to the engine muffler.
NEVER operate the engine without the
muffler and spark arrester screen in
place.
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.
Make sure the
obstructions!

5. 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.
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.
