WARNING!
Alternative fuels, such as E15 (15% ethanol), E-85 (85% ethanol) or any fuels not meeting Shindaiwa
requirements are NOT approved for use in Shindaiwa gasoline engines. Use of alternative fuels may cause
performance problems, loss of power, overheating, fuel vapor lock, and unintended machine operation, including,
but not limited to, improper clutch engagement. Alternative fuels may also cause premature deterioration of fuel
lines, gaskets, carburetors and other engine components.
Fuel Requirements
Gasoline - Use 89 Octane [R+M/2] (mid grade or higher) gasoline known to be good quality. Gasoline may contain
up to 10% Ethanol (grain alcohol) or 15% MTBE (methyl tertiary-butyl ether). Gasoline containing methanol (wood
alcohol) is NOT approved.
2 Stroke Mixture Oil - A 2-stroke engine oil meeting ISO-L-EGD (ISO/CD 13738) and J.A.S.O. M345/FD standards
must be used. Shindaiwa OneTM 2-Stroke Oil is strongly recommended as it meets this standard and is specically
formulated for use in all Shindaiwa 2-stroke engines. Engine problems due to inadequate lubrication caused by fail-
ure to use an ISO-L-EGD (ISO/CD 13738) and J.A.S.O. M345/FD certied oil will void the engine warranty.
Mixing Fuel
For increased engine protection, Shindaiwa recommends using Shindaiwa Red ArmorTM engine oil to protect the
engine from harmful carbon build up, maintain engine performance, and increase engine life. Shindaiwa Red
ArmorTM engine oil exceeds ISO-L-EGD and J.A.S.O. M345/FD performance requirements.
Examples of 50:1 mixing quanti-
ties
IMPORTANT!
Shindaiwa OneTM 2-Stroke oil or Red ArmorTM engine oil may be mixed at 50:1
ratio for application in all Shindaiwa engines sold in the past, regardless of ratio
specied in those manuals.
IMPORTANT!
Stored fuel ages. Do not mix more fuel than you expect to use in thirty (30)
days, ninety (90) days when a fuel stabilizer is added. Use of unmixed, improp-
erly mixed, or stale fuel, may cause hard starting, poor performance, or severe
engine damage and void the product warranty. Read and follow instructions in
the Long Term Storage section of this manual.
Handling Fuel
DANGER
Fuel is VERY ammable. Use extreme care when mixing, storing or handling or serious personal injury may result.
• Use an approved fuel container.
• DO NOT smoke near fuel.
• DO NOT allow ames or sparks near fuel.
• Fuel tanks/cans may be under pressure. Always loosen fuel caps slowly allowing pressure to equalize.
• NEVER refuel a unit when the engine is HOT or RUNNING!
• DO NOT ll fuel tanks indoors. ALWAYS ll fuel tanks outdoors over bare ground.
• DO NOT overll fuel tank. Wipe up spills immediately.
• Securely tighten fuel tank cap and close fuel container after refueling.
• Inspect for fuel leakage. If fuel leakage is found, do not start or operate unit until leakage is repaired.
• Move at least 3m (10 ft.) from refueling location before starting the engine.

10
Storage - Fuel storage laws vary by
locality. Contact your local govern-
ment for the laws affecting your area.
As a precaution, store fuel in an ap-
proved, airtight container. Store in a
well-ventilated, unoccupied building,
away from sparks and ames.
IMPORTANT!
Stored fuel may separate. ALWAYS
shake fuel container thoroughly
before each use.
Mixing Instructions
1. Fill an approved fuel container with half of the required amount of gasoline.
2. Add the proper amount of engine oil to gasoline.
3. Close container and shake to mix oil with gasoline.
4. Add remaining gasoline, close fuel container, and remix.
IMPORTANT!
Spilled fuel is a leading cause of hydrocarbon emissions. Some states may
require the use of automatic fuel shut-off containers to reduce fuel spillage.
After use
• DO NOT store a unit with fuel in its tank. Leaks can occur. Return unused fuel
to an approved fuel storage container.
Remove
the
Fuel
Filler
Cap
Filling the Fuel Tank
1. Place the unit on a at, level surface.

Using The Blower
Operating Tips
In the hands of an experienced opera-
tor, the blower can efciently move
a wide variety of debris ranging from
grass clippings to gravel. As a general
rule, operate your blower at the lowest
throttle setting required to get the job
done:
■Use low throttle settings when
clearing lightweight materials from
around lawns or shrubbery.
■Use medium to higher throttle set-
tings to move grass or leaves from
parking lots or walkways.
■Use full throttle when moving heavy
loads such as dirt or snow.
IMPORTANT!
Blower noise increases at higher
throttle settings! Always use the lowest

Maintenance (continued)
Daily Maintenance
WARNING!
To reduce re hazard, keep
the engine and mufer free of dirt,
debris, and leaves.
■Inspect the engine, tank, and hoses
for possible fuel leaks, and repair
as necessary.
■Inspect the entire blower for loose,
damaged, or missing components,
and repair as necessary.
■Carefully remove any accumula-
tions of dirt or debris from the
mufer and fuel tank. Dirt build-up
in these areas can lead to engine
overheating, re or premature wear.
CAUTION!
The engine is cooled by air drawn
into the air intake cover on the
blower housing. The blower fan then
pushes the cooling air through an
opening in the fan housing, forcing it
past the cylinder cooling ns. Failure
to keep the cooling system and its
passages clear of debris will likely
result in engine overheating, a major
cause of serious engine problems
that can lead to failure.
Prior to each workday, perform the
following:
■Remove all dirt and debris from
blower exterior and the engine.
Check the cooling ns and air
cleaner for clogging and clean as
necessary.

■Replace the spark plug annually:
Use only NGK BPMR8Y or equiva-
lent resistor type spark plug of the
correct heat range. Set spark plug
electrode gap to 0.6 mm (0.024
inch).
NOTE:
The NGK BPMR8Y also meets the require-
ments for electro-magnetic compliance
(EMC).

fuel tank.
(more frequently if reduced perfor-
mance is noted)
■Inspect the lter element for signs
of contamination from debris. A
contaminated fuel lter should be
replaced with a new Shindaiwa
replacement element. Before rein-
stalling the lter, inspect the con-
dition of the fuel line. If you note
damage or deterioration, the blower
should be removed from service
until it can be inspected by a Shin-
daiwa-trained service technician.
■COOLING SYSTEM Use a wood
or plastic scraper and a soft brush
to remove dirt and debris from the
cylinder ns and crankcase.
Every 50 Hours
CAUTION!
Make sure you do not pierce the fuel
line with the end of the hooked wire.

1. Place the unit on the ground and
start the engine, then allow it to idle
2-3 minutes until warm.
2. If a tachometer is available, the
engine idle speed should be nal
adjusted to 2,000 (±200) RPM.
NOTE:
Carburetor fuel mixture adjustments are
preset at factory on units with emission
control systems and cannot be serviced
in the eld.
IMPORTANT!
Blower tubes and the air cleaner must
be in place while adjusting engine idle!
Engine idle speed will also be affected
if the blower tubes are blocked or incor-
rectly installed!
Carburetor Adjustment
Engine Break-In
New engines must be operated a minimum duration of two tanks of fuel break-in before carburetor adjustments can be
made. During the break-in period your engine performance will increase and exhaust emissions will stabilize. Idle speed can
be adjusted as required.
NOTE:
Every unit is run at the factory and the carburetor is set in compliance with emission regulations. Carburetor adjustments,
other than idle speed, must be performed by an authorized Shindaiwa dealer.
IMPORTANT!!
If the engine is adjusted for operation above 1,100 feet ASL, the carburetor must be re-adjusted when operating the
engine below 1,100 feet ASL, otherwise severe engine damage may result.
High Altitude Operation
This engine has been factory adjusted to maintain satisfactory starting, emission, and durability performance up to
1,100 feet above sea level (ASL) (96.0 kPa). To maintain proper engine operation and emission compliance above
1,100 feet ASL the carburetor may need to be adjusted by an authorized Shindaiwa service dealer.
Long Term Storage
CAUTION!
Gasoline stored in the carburetor for
extended periods can cause hard start-
ing, and could also lead to increased
service and maintenance costs.
Whenever the unit will not be used
for 30 days or longer, use the follow-
ing procedures to prepare it for storage:
• Clean external parts thoroughly.
• Drain all the fuel from the fuel tank.
IMPORTANT!
Stored fuel ages. Do not mix more fuel
than you expect to use in thirty (30)
days, ninety (90) days when a fuel sta-
bilizer is added.
• Remove the remaining fuel from the
fuel lines and carburetor.
1. Prime the primer bulb until no more
fuel is passing through.
2. Start and run the engine until it
stops running.
3. Repeat steps 1 and 2 until the
engine will no longer start.
• Remove the spark plug and pour
about 1/4 ounce of engine oil into the
cylinder through the spark plug hole.
Slowly pull the recoil starter 2 or 3
times so oil will evenly coat the inte-
rior of the engine. Reinstall the spark
plug.
• Before storing the unit, repair or
replace any worn or damaged parts.
• Remove the air cleaner element
from the carburetor and clean it
thoroughly.
• Store the unit in a clean, dust-free
