this unit.
WARNING!
WARNING!
Use Good Judgment
ALWAYS wear eye protection that complies with ANSI Z 87.1 or your ap-
plicable national standard to shield against thrown objects.
NEVER run the engine indoors! Make sure there is always good ventilation. Fumes from engine exhaust can cause serious injury or death.
ALWAYS stop the unit immediately if it suddenly begins to vibrate or
shake. Inspect for broken, missing or improperly installed parts.
ALWAYS keep the unit as clean as practical. Keep it free of loose vegetation, mud, etc.
ALWAYS keep the handles clean.
ALWAYS disconnect the spark plug wire before performing any mainte-
nance work.
ALWAYS turn off the engine before putting the unit down. When transporting the unit in a vehicle, properly secure it to prevent the unit from over
turning, fuel spillage and damage to the unit.
NEVER insert any foreign objects into the air intake or outlet opening of
the blower while in operation.
Never operate power equipment
of any kind if you are tired or if you
are under the inuence of alcohol,
drugs, medication or any other
substance that could affect your

Be Aware of the Working Environment
Reduce the risk of bystanders
being struck by ying debris.
Make sure no one is within
15 m (50 feet)—that’s
about 16 paces—of an
operating blower.
Make sure bystanders
15
METERS
Do not direct the air blast
towards bystanders. The high
air ow could blow small
objects at great speed
causing possible eye injury.
Be constantly alert
for objects and debris that
could be thrown from

or very cold weather.
Never operate the
blower if any
component parts
are damaged,
loose, or missing!
Be extremely careful of
slippery terrain, especially
during rainy weather.
Never operate this blower
on a roof, ledge or ladder.

Mixing Fuel
WARNING!
Alternative fuels, such as E15 (15% ethanol), E-85 (85% ethanol) or any fuels not meeting Shin-
daiwa 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.
Hybrid 4TM Mixture Oil - Engine oil meeting ISO-L-EGD (ISO/CD 13738) and J.A.S.O. M345/FD standards must be
used. Shindaiwa highly recommends using Shindaiwa Red ArmorTM engine oil in all Shindaiwa Hybrid 4TM engines 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. Engine problems
due to inadequate lubrication caused by failure to use an ISO-L-EGD (ISO/CD 13738) and J.A.S.O. M345/FD certied
oil will void the engine warranty.
IMPORTANT!
Shindaiwa Red ArmorTM engine oil may be mixed at 50:1 ratio for applica-
tion in all Shindaiwa engines sold in the past, regardless of ratio specied
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,
improperly 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.
Examples of 50:1 mixing quantities
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 overll 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.

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.
Filling the Fuel Tank
1. Place the blower on a at, level surface.
2. Clear any dirt or other debris from around the fuel ller cap.
3. Remove the fuel cap, and ll the tank with clean, fresh fuel.
4. Reinstall the fuel ller cap and tighten rmly.
5. Wipe away any spilled fuel before starting the blower.
Starting the Engine
The impeller will rotate whenever the blower is operated! Never operate
this blower unless the intake cover and blower tubes are properly installed
and in good working order!
WARNING!
Danger from thrown dust or debris!
Always wear eye protection when operating this machine! Never direct the
blower stream toward people or animals!
Never operate this blower unless all controls are properly installed and in
good working order.
WARNING!
Danger from rotating impeller!
Storage - Fuel storage laws vary by
locality. Contact your local government for the laws affecting your area.
As a precaution, store fuel in an approved, 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.

Figure 4
Starting Procedure
1. Place the blower on the ground.
2. Prime the fuel system by repeatedly
depressing the fuel primer bulb
until no air bubbles are visible in
the fuel discharge line.
IMPORTANT!
The primer system only pushes fuel
through the carburetor. Repeatedly
pressing the primer bulb will not ood
the engine with fuel.
CAUTION!
The recoil starter can be damaged by abuse!
• Never pull the starter cord to its full length!
• Always engage the starter before cranking the engine!
• Always rewind the starter cord slowly!
Never operate the blower if blower tubes are missing or damaged!
