starting engine. Place sweeper
belts on a smooth level surface
when starting.
■ Always make sure the Power-
Broom attachment is properly
installed and rmly tightened
before operation.
■ Always wear eye protection to
shield against thrown objects.
■ Never modify or disable any of the
unit’s safety devices.
■ Do not make unauthorized modi-
cations to this unit.
■ Make sure there are no missing or
loose fasteners, and that the ignition switch and throttle controls
are working properly.
■ Do not operate the unit with the
mufer removed.
■ NEVER operate this unit indoors.
Operate this unit only in a well ventilated area. Be aware of carbon
monoxide poisoning. Exhaust gases
and lubrication oil mist can cause
serious injury or death.
■ Always hold the machine rmly with
both hands when sweeping, and
maintain control at all times.

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.
Never operate the PowerBroom around
objects that could tangle in the drums
and cause loss of control.
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 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.
Be constantly alert for objects and debris that could be
thrown either from the sweeper belts or bounced from a
hard surface.
Never allow the engine to run at
high RPM without a load. Doing
so could damage the engine.
When transporting the unit in a
vehicle, tie it down securely to
prevent damage and fuel spillage.
Always keep the
handles clean.
Keep the unit as clean as
possible. Keep it free of
loose vegetation, mud,
etc.
Do not use this unit on
rooftops or elevated surfaces

An Emission Control Label is located on the engine. (This is an EXAMPLE ONLY; information on label varies by engine
FAMILY).
PRODUCT EMISSION DURABILITY (EMISSION COMPLIANCE PERIOD)
The 300 hour emission compliance period is the time span selected by the manufacturer certifying the engine emissions output meets applicable emissions regulations, provided that approved maintenance procedures are followed as
listed in the Maintenance Section of this manual.
Emission Control (Exhaust & Evaporative)
EPA 2010 and Later and/or C.A.R.B. TIER III
The emission control system for the engine is EM (engine modication) and, if the second to last character of the Engine
Family on the Emission Control Information label (sample below) is “C”, “K”, or “T”, the emission control system is EM and
TWC (3-way catalyst). The fuel tank/fuel line emission control system is EVAP (evaporative emissions). Evaporative emissions for California models may only be applicable to fuel tanks.

The PowerBroom tool should now be
completely assembled.
1. Push one of the drum axles onto
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.
2. Use a clevis pin and hitch pin to
secure the drum axle to the shaft.
3. Slide the recessed end of a
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.
4. Use a cotter pin to secure the drum
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.
5. Repeat Steps 1-4 to install the
remaining axle and drum assembly.

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.
Mixing Fuel
Examples of 50:1 mixing quantities
IMPORTANT!
Shindaiwa Red Armor
TM
engine oil may be mixed at 50:1 ratio for application
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.
