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™.
Starting the Engine
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.
3. 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 ood 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.
Filling the Fuel Tank
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 exces-
sive carbon deposits.
CAUTION!
Some types of gasoline contain alcohol
as an oxygenate. Oxygenated gasoline
may cause increased operating tem-
peratures. Under certain conditions,
alcohol-based gasoline may also reduce
the lubricating qualities of some 2-cycle
mixing oils. Never use any type of gaso-
line 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.
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 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 and also includes a fuel stabilizer.
1. Slide the ignition switch to the “ON”
position. See Figure 16.
2. Set the throttle lever to the “fast idle”;
a. Squeeze the throttle lever toward the
handgrip.
b. Depress and hold the throttle lock
button.
c. While depressing the throttle lock
button, release the throttle lever. See
Figure 16.

WARNING!
Minimize the Risk of Fire
n
NEVER
smoke or light res near the
engine.
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 ALWAYS inspect the unit for fuel leaks
before each use. During each rell,
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
repaired before using the unit.
n ALWAYS move the unit at least 10
feet (3 meters) away from a fuel stor-
age area or other readily ammable
materials before starting the engine.
n NEVER place ammable material
close to the engine mufer.
n NEVER operate the engine without
the mufer and spark arrester screen
in place.
