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.
Keep bystanders
at least 15 meters
away from the unit
while operating
to reduce the risk
of being struck by
thrown debris.
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 the unit as clean as
possible. Keep it free of
loose vegetation, mud,
etc.
Maintain a low working angle
and avoid steep angles of
operation. A steep working
angle risks loss of control of
the machine.
Transport the
machine with the
engine OFF.
Always keep the
handles clean.

Assembly (continued)
Push one of the drum axles onto 1.
either of the two gearcase output
shafts. If necessary, rotate the drum
axle until the clevis pin hole in the
axle aligns with the matching hole
in the gearcase output shaft.
CAUTION!
The two drum assemblies are
identical, but each drum must be
installed with its recessed end
facing toward the gearcase.
Use a clevis pin and hitch pin to 2.
secure the drum axle to the shaft.
Slide the recessed end of a 3.
sweeper drum assembly over the
installed axle, and then push the
drum down the axle until the cotter
pin hole in the axle extends above
the drum surface.
Use a cotter pin to secure the drum 4.
assembly on the axle (see inset).
The cotter pin is designed to t
tightly against the outboard end of
the drum, so you may need to compress the drum face slightly during
installation. spead the ends of the
cotter pin to secure.
Repeat Steps 1-4 to install the 5.
remaining axle and drum assembly.
The PowerBroom tool should now be
completely assembled.
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.

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 shutoff containers to reduce fuel spillage.
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.
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
CAUTION!
Slowly remove the fuel cap only after stopping the engine
WARNING!
Minimize the Risk of Fire
NEVER ■ smoke or light res near the engine.
■ stop the engine and allow it to cool before
ALWAYS
refueling.
■ Wipe all spilled fuel and move at least 3
ALWAYS
meters (10 feet) from the fueling point and source before
starting.
■ place ammable material close to the engine
NEVER
mufer.
NEVER ■ operate the engine without the mufer and spark
arrester screen in place and in good working condition.
FUEL IS HIGHLY FLAMMABLE. ■
Place the unit on a at, level surface.1.
Clear any dirt or other debris from around the fuel ller cap.2.
ALWAYS ■ store gasoline in a container approved for
ammable liquids.
■ inspect the unit for fuel leaks before each
ALWAYS
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.
ALWAYS ■ move the unit at least 3 meters (10 feet)
away from a fuel storage area or other readily am-
mable materials before starting
the engine.
Remove the fuel cap, and ll the tank with clean, fresh 3.
fuel.
Reinstall the fuel ller cap and tighten rmly.4.
Wipe away any spilled fuel before starting engine.5.
