Mixing Fuel
ENGLISH
CAUTION!
Some gasolines contain alcohol as an
oxygenate! Oxygenated fuels may
cause increased operating temperatures. Under certain conditions,
alcohol-based fuels may also reduce
the lubricating qualities of some
mixing oils. Never use any fuel
containing more than 10% alcohol by
volume!
Generic oils and some outboard
motor oils may not be intended for
use in high-performance air cooled 2cycle engines, and should never be
used in your Shindaiwa engine!
CAUTION!
This engine is designed to operate on
a 50:1 mixture consisting of unleaded
gasoline and a premium 2-cycle
mixing oil only. Use of non-approved
mixing oils can lead to excessive
maintenance costs and/or engine
damage.
■ Use only fresh, clean unleaded
gasoline with a pump octane rating of
87 or higher.
■ Mix gasoline with 50:1 Shindaiwa
Premium 2-cycle mixing oil or with an
equivalent high quality 2-cycle mixing
oil.
Example of 50:1 mixing quantites:
■ 1 gallon of gasoline to 2.6 oz. mixing
oil.
■ 5 liters of gasoline to 100 ml. mixing
oil.
IMPORTANT!
Mix only enough fuel for your immediate
needs! If fuel must be stored longer than
30 days and Shindaiwa One oil with fuel
stabilizer is not used, it should first be
treated with a fuel stabilizer such as
StaBil™.
Filling the Fuel Tank
WARNING!
Minimize the risk of fire!
■ STOP the engine before refueling.
■ ALWAYS allow the unit to cool
before refueling!
■ Wipe all spilled fuel and move the
unit at least 10 feet (3 meters) from
the fueling point before restarting!
■ NEVER start or operate this unit if
there is a fuel leak.
■ NEVER start or operate this unit if
the carburetor, fuel lines, fuel tank
and/or fuel tank cap are damaged.
■ NEVER smoke or light any fires
near the unit or fuels!
■ NEVER place any flammable
material near the engine muffler!
■ NEVER operate the engine without
the muffler and spark arrester in
place and properly
functioning!
1. Place the PowerBroom on a flat, level
surface.
2. Clear any dirt or other debris from
around the fuel filler cap.
3. Remove the fuel cap, and fill the tank
with clean, fresh fuel.
4. Reinstall the fuel filler cap and tighten
firmly.
Break-in and Operation
The PowerBroom works best when its
rubber fins can quickly slide or “skim”
over the surface being swept.
New or replacement sweeper belts
tend to grip or drag on hard surfaces, and
should be thoroughly broken in or
“scuffed” before the broom is actually put
to work.
Break-in is easily accomplished by
operating the PowerBroom at full throttle
for 3 to 5 minutes in loose gravel or
similar abrasive material. Once broken in,
a PowerBroom will effortlessly move an
amazing variety of materials, ranging
from snow or standing water to heavier
objects such as gravel or wood chips.
Experience will help you understand
the operating principles of the
PowerBroom, but safe operation must be
practiced from the start.
WARNING!
BURN DANGER! The gearcase will
become very hot during normal
operation.

Starting the Engine
2
IMPORTANT!
Engine ignition is controlled by a two
position switch mounted on the throttle
housing labeled, "I" for ON or START
and "O" for OFF or STOP.
ON
Make sure the
sweeper belts
are clear of
obstructions!
IMPORTANT!
If the engine fails to start after several
attempts with the choke in the closed
position, the engine may be flooded with
fuel. If flooding is suspected, move the
choke lever to the open position and
repeatedly pull the recoil starter to
remove excess fuel and start the engine.
If the engine still fails to start, refer to the
troubleshooting section of this manual
(Starting a flooded engine).
ENGLISH

Return
Figure 16
Primer Bulb
Tube
2. Press the primer bulb until fuel can be
seen flowing in the transparent return
tube.
IMPORTANT!
The primer system only pushes fuel
through the carburetor. Repeatedly
pressing the primer bulb will not flood
the engine with fuel.
PB2500.13
Figure 18
4. While holding the outer tube firmly
with left hand. Use your other hand to
slowly pull the recoil starter handle
until resistance is felt, then pull
quickly to start the engine.
CAUTION!
Do not pull the recoil starter to the
end of the rope travel. Pulling the
recoil starter to the end of the rope
travel can damage the starter.
WARNING!
The sweeper belts may rotate when
the engine is started!
5. When the engine starts, slowly move
the choke lever to the "OPEN"
position. See Figure 19. (If the engine
stops after the initial start, close the
choke and restart.)
Open
When the Engine Starts...
■ After the engine starts, allow the
engine to warm up at idle 2 or 3
minutes before operating the unit.
■ After the engine is warm, pick
up the unit and clip on the shoulder
strap if so equipped. See page 16.
■ Advancing the throttle makes the
sweeper belts turn faster; releasing the
throttle permits the attachment to stop
turning. If the sweeper belts continue
to rotate when the engine returns to
idle, carburetor idle speed should be
adjusted (see the next page).
Stopping the Engine
PB19
Figure 20
Idle the engine briefly before stopping
(about 2 minutes), then slide the ignition
switch to the “O” (Engine OFF) position.
Closed

position if engine is cold.
Figure 19
PB2500.14
WARNING!
Never start the engine from the
operating position.
11
Adjusting Engine Idle
ENGLISH
The engine must return to idle speed
whenever the throttle lever is released.
Idle speed is adjustable, and must be set
low enough to permit the engine clutch
to disengage the cutting attachment.
Idle Speed Adjustment
WARNING!
The cutting attachment must NEVER
rotate at engine idle! If the idle speed
cannot be adjusted by the procedure
described here, return the trimmer to
your Shindaiwa dealer for inspection.
Operating Techniques
Operate the PowerBroom at or near full
throttle with its sweeper fins resting on
the work surface.
IMPORTANT!
It is both tiring and unnecessary to lift or
hold the fins from the work surface
during sweeping.
When sweeping narrow areas such as
sidewalks, the PowerBroom can be used
to throw material directly ahead of the
operator. Clearing wider areas may
require sweeping at an angle to create
windrows to one side of the path being
cleared.
Windrows of lighter materials often
can be combined into one main row or
pile for eventual pickup, while heavy or
bulky material may need to be collected
row-by-row. See Figure 22.
To pull debris from corners, reverse
sweeper drum rotation by turning the
powerhead over (throttle facing “up”).
See Figures 23 and 24.
WARNING!
Reversing the PowerBroom will cause
debris to be thrown back toward the
operator. When reversing the
PowerBroom, use lower throttle
settings and be aware that thrown
debris may also affect your footing!
PB2500.16
Idle Adjusting
Figure 21
Screw
1. Place the trimmer on the ground, then
start the engine, and then allow it to
idle 2-3 minutes until warm.
2. If the attachment rotates when the
engine is at idle, reduce the idle speed
by turning the idle adjustment screw
counter-clockwise.
See Figure 21.
3. If a tachometer is available, the engine
idle speed should be final adjusted to
3,200 (±300) rpm (min
