Safety (continued)
The Properly Equipped Operator
Always protect yourself from hazards
such as thorny brush and ying debris
by wearing gloves and close tting
clothing that covers arms and legs.
Never wear shorts. Don’t wear loose
clothing or items such as jewelry that
could get caught in machinery or
underbrush. Secure long hair so it is
above shoulder level.
Keep a proper footing and do not
overreach—maintain your balance
at all times during operation.
Wear sturdy footwear with nonslip
soles to provide good footing. Steeltoed safety boots are recommended.
Never operate unit bare-footed!
Always wear eye and hearing protection.
Shindaiwa recommends wearing a face shield as
additional face and eye protection.
Always operate with both hands
rmly gripping the unit.
Keep away from rotating
sweeper belts or bristles at
all times, and NEVER lift a
moving attachment above
waist-height.
Be Aware of the Working Environment
Be careful when operating on a slope or on slippery
terrain, especially during rainy weather or when pulling
debris toward you.
If the drum assemblies jam, switch the
engine OFF and inspect the drums,
axles and gearcase for damage.
Do not use this unit on
rooftops or elevated surfaces
When transporting the unit in a
vehicle, tie it down securely to
prevent damage and fuel spillage.
Never operate the PowerBroom around
objects that could tangle in the drums
and cause loss of control.
Never allow the engine to run at
high RPM without a load. Doing
so could damage the engine.
Be constantly alert for objects and debris that could be
thrown either from the sweeper belts or bounced from a
hard surface.
ALWAYS clear your work area of trash or
hidden debris that could be thrown back at you
or toward a bystander. When operating in rocky
terrain or near electric wires or fences, use
extreme caution to avoid contacting such items
with the sweeper belts.
Keep bystanders
at least 15 meters
away from the unit
while operating
to reduce the risk
of being struck by
thrown debris.
Keep the unit as clean as
possible. Keep it free of loose
vegetation, mud, etc.

Mixing Fuel
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.
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 Armor
in all Shindaiwa engines sold in the past, regardless of ratio specied in those
manuals.
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.
TM
engine oil may be mixed at 50:1 ratio for application
IMPORTANT!
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.
