CAUTION
Never use any type of gasoline contain-
ing more than 10% alcohol by volume!
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.
Generic oils and some outboard
oils may not be intended for use in
high-performance 2-cycle engines,
and should never be used in your
Shindaiwa engine.
Mixing fuel
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 FD
class 2-cycle mixing oil only. Use of
non-approved mixing oils can lead to
excessive carbon deposits.
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 FD classified oils at
50:1 gasoline/oil ratio.
Examples of 50:1 mixing quantities
WARNING!
Minimize the Risk of Fire
Gasoline 2-cycle mixing oil
liters milliliters
2.5 - L 50 mL
5 - L 100 mL
10 - L 200 mL
20 - L 400 mL
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™.
Oil is a registered JASO FD 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. Shindaiwa One also includes a
fuel stabilizer.
NEVER smoke or light fires near the
engine.
ALWAYS stop the engine and allow
it to cool before refueling.
ALWAYS Wipe all spilled fuel and
move at least 3 meters (10 feet)
from the fueling point and source
before starting.
NEVER place flammable material
close to the engine muffler.
NEVER operate the engine with-
out the muffler and spark arrester
screen in place and in good work-
ing condition.
FUEL IS HIGHLY FLAMMABLE.
ALWAYS store gasoline in a con-
tainer approved for flammable
liquids.
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 repaired before using the unit.
ALWAYS move the unit at least 3
meters (10 feet) away from a fuel
storage area or other readily flam-
mable materials before starting
the engine.
Place the unit on a flat, level surface.1.
Clear any dirt or other debris from2.
around the fuel filler cap.
Remove the fuel cap, and fill the tank3.
with clean, fresh fuel.
Reinstall the fuel filler cap and tighten4.

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.
WARNING!
Never start the engine from
the operating position.
When the engine starts, slowly move5.
the choke lever to the “OPEN” position.
If the engine stops after the initial start,
close the choke and restart.
IMPORTANT!
The primer system only pushes fuel
through the carburetor. Repeatedly press-
ing 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.
WARNING!
The cutting attachment may
rotate when the engine is started!
IMPORTANT!
If the engine fails to start after several
attempts with the choke in the closed
position, the engine may be flooded with
fuel. If flooding is suspected, see the sec-
tion “Starting a Flooded Engine” for more
information
After the engine starts, allow the engine
to warm up at idle for 2 or 3 minutes
before operating the machine.
Advancing the throttle makes the cut-
ting attachment rotate faster; releasing
the throttle makes the attachment stop
running. If the cutting attachment con-
tinues to rotate refer to “Engine Idle
Adjustment” for engine idle adjust-
ment procedures.
When the engine starts
After the engine is warm, pick up the
unit and clip on the strap or harness if
so equipped. See the section “Opera-
tion: Shoulder Strap” for instructions.
Starting a warm engine involves all of the
steps of starting a cold engine, EXCEPT:
Starting a warm engine
Do not press the primer bulb.
The choke should be in the OPEN ( )
position.
If the engine does not start, follow the cold
engine starting procedure.
WARNING!
Keep all parts of your body
away from the rotating cutting attach-
ment and hot surfaces.
WARNING!
Never start the engine without
the tool assembly and cutting attach-
ments installed to the engine. Failure
to do so could damage the engine and
increase unexpected risk to the opera-
tor and any bystander.

Slide ignition to OFF
OFF
IMPORTANT
When the unit is turned off make sure the

Stopping the Engine
Adjusting Engine Idle
Idle Adjusting
Screw
The engine must return to idle speed
whenever the throttle lever is released.
Idle speed is adjustable, and must be set
low enough to permit the engine clutch to
disengage the cutting attachment.
Idle Speed Adjustment
WARNING!
The cutting attachment must
NEVER rotate at engine idle! If the
idle speed cannot be adjusted by the
procedure described here, return the
trimmer to your Shindaiwa dealer for
inspection.
Place the unit on the ground, then start1.
the engine, and then allow it to idle 2-3
minutes until warm.
If the attachment rotates when the2.
engine is at idle, reduce the idle speed
by turning the idle adjustment screw
counter-clockwise.
If a tachometer is available, the engine3.
idle speed should be final adjusted
to the settings recommended in the
Specifications section.
NEVER operate the unit with the cutting
attachment shield or other protective
devices removed!
Use only authorized Shindaiwa parts and
accessories with your Shindaiwa trimmer.
Do not make modifications to this unit with-
out written approval from Shindaiwa, Inc.
ALWAYS make sure the cutting attach-
ment is properly installed and firmly
tightened before operation.
NEVER use a cracked or warped cutting
attachment: replace it with a serviceable
one.
Checking Unit Condition
The cutting attachment may be moving
during carburetor adjustments. Wear your
protective equipment and observe all
safety instructions.
ALWAYS make sure the cutting attach-
ment fits properly into the appropriate
attachment holder. If a properly installed
attachment vibrates, replace the attach-
ment with new one and re-check.
ALWAYS stop the engine immediately and
check for damage if you strike a foreign
object or if the unit becomes tangled.
Do not operate with broken or damaged
equipment.
NEVER allow the engine to run at high
RPM without a load. Doing so could dam-
age the engine.
NEVER operate a unit with worn or dam-
aged fasteners or attachment holders.
When transporting, make sure the engine
is not running and blades are covered with
blade covers.
WARNING!
A cutting attachment shield
or other protective device is no
guarantee of protection against rico-
chet. YOU MUST ALWAYS GUARD
AGAINST FLYING DEBRIS!

components.
Daily maintenance
10-hour maintenance
Make sure nuts, bolts, and screws
(except carburetor idle speed adjusting
screws) are tight.
Carefully remove any accumulations of dirt
or debris from the muffler and fuel tank.
Check cooling air intake area at base of
crankcase. Remove all debris. Dirt build-up
in these areas can lead to engine overheat-
ing, fire, or premature wear.

the spark plug electrode gap to 0.6 - 0.7 mm
(0.024 - 0.028 inch). If the spark plug must
be replaced, use only the an NGK BPMR6A
or equivalent resistor type spark plug of the
correct heat range
CAUTION!
Before removing the spark plug, clean
the area around the plug to prevent
dirt and debris from getting into the
engine’s internal parts.
10/15 hour maintenance
Maintenance (continued)
NOTE
The NGK BPMR6A also meets the
requirements for electro magnetic compli-
ance (EMC).
Before reinstalling the new filter element,
inspect the condition of all the fuel system
components (fuel pick-up line, fuel return
line, tank vent line, tank vent, fuel cap
and fuel tank). If damage, splitting or
deterioration is noted, the unit should
be removed from service until it can be

engine will no longer start.
Remove the spark plug and pour about
7.4 mL (1/4 oz.) of 2-cycle mixing oil
into the cylinder through the spark plug
hole. Slowly pull the recoil starter 2 or 3
times so oil will evenly coat the interior
of the engine. Reinstall the spark plug.
IMPORTANT!
All stored fuels should be stabilized with a
fuel stabilizer such as STA-BIL, if oil
with fuel stabilizer is not used.
CAUTION
Gasoline stored in the carburetor for
extended periods can cause hard start-
ing, and could also lead to increased
