SAFETY
WARNING
Gasoline is highly Àammable and gasoline
vapor is explosive. Never smoke while
working on vehicle. Keep all open Àames
away from gasoline tank and lines. Wipe up
any spilled gasoline immediately.
WARNING
Engine exhaust contains lethal fumes.
Breathing these fumes, even in low
concentrations, can cause death. Never
operate an engine in an enclosed area without
venting exhaust to the outside.
TORQUE CHART
CAUTION
Read instructions before assembling.
Fasteners should be ¿nger tight until
instructed to tighten according to the torque
chart. Use standard methods and practices
when assembling the rotary broom, including
proper personal protective safety equipment.

Lit. No. 72356, Rev. 00 9 March 1, 2019
OPERATING IN WINTER
Check regularly that the air ¿lter is dry. If the air
¿lter has become wet, let it dry overnight. There is a
possibility of the engine not starting due to a clogged
air ¿lter.
Spray the throttle cable with silicone spray at both
ends and the throttle linkage before operating to
prevent the cable or throttle mechanism from freezing
up.
Silicone spray attracts dust and binds it to the rotary
broom. It is only a suitable lubricant in wintry and
snowy conditions.
Do not spray silicone spray on hot engine. It could
cause a ¿re. Follow the instructions on the spray can.
Before putting the rotary broom away, sweep it clear of
snow.
Avoid freezing the rotary broom. Store the rotary
broom in a frost-free room.
Remove foam pre-¿lter.
Use SAE 5W-30 motor oil.
GENERAL SAFETY
Do not operate the rotary broom in an unsafe
manner. Make yourself familiar with the surroundings
before starting work in a new location. The working
surroundings include any obstacles in the work area or
on roads, the ground load-bearing capacity, and any
necessary workplace safety precautions in live traf¿c.
Take precautions to ensure that the rotary broom is
only operated in a safe and functional condition. Only
operate the rotary broom if all protective and safety
devices are present and working.
Check the rotary broom for externally visible damage
and faults before operation. If malfunctions occur stop
the rotary broom and secure it immediately. Repair
malfunctions immediately. Only start the rotary broom
from the operator's position. Ensure that no one can
be endangered by starting the rotary broom before
switching it on or operating it.
Check that braking, steering, and brushing are fully
functional before operation.
Before operating the rotary broom, always check that
accessories are ¿tted correctly.
Always observe applicable traf¿c regulations before
operating on public roads, paths, or parks, and ensure
that the rotary broom is in a condition suitable for use
in traf¿c.
Always ensure that suitable lighting is available before
working in poor light or darkness. Always keep a
suf¿cient distance between the rotary broom and
drop-offs, holes, or slopes.
Do not permit any method of working which will affect
the stability of the rotary broom.
Never traverse across slopes; always travel up and
down, not across.
Adjust the speed to suit the conditions on inclines.
Change gear before the incline, not on it. Always
secure the rotary broom against rolling away and
unauthorized operation before leaving it unattended.

not press any levers.

Lit. No. 72356, Rev. 00 13 March 1, 2019
OPERATING INSTRUCTIONS
Shutting Down the Motor
Move the throttle to the "OFF" position.
ADJUSTING HANDLEBAR HEIGHT
There are four settings for adjusting the handlebar height.
1. Push the adjustment lever with your foot.
2. Adjust handlebars to the desired height. Release
the lever.
3. Fold the handlebars forward to save space when
storing.

OPERATING INSTRUCTIONS
TRANSPORTING
Carrying
Position hands to hold the front of the broom as shown
below.
Securing for Transport
1. Position the strap at the front of the broom as
shown.
2. Position the straps at the rear of the broom as
shown.
3. To save space when transporting, fold the
handlebars forward.

Lit. No. 72356, Rev. 00 15 March 1, 2019
ADJUSTING DISCHARGE DIRECTION
There are four settings available for the discharge
direction: three primary positions and a sideways
position when using the optional accessories.
Forward Discharge Direction:
The swept material will heap up in front of the brushes.
You should give preference to angled brush settings.
To adjust brush angle: Lift the lever. Turn the brush
in the desired direction. Release the lever, and ensure
that the lever is latched in place.
Right Discharge Direction:
With an angled setting, the material will be swept to
one side.
Left Discharge Direction:
Sideways Discharge Direction
(available with optional accessories):
A sideways setting is recommended if using the
optional debris collector box and optional debris
shield. This will allow sweeping against a wall or curb.

OPERATING INSTRUCTIONS
SWEEPING
1. Lift up the brushes by pushing down on the
handlebars. Engage the brushes.
2. Carefully lower the brushes to the ground.
3. Engage the movement drive. Just follow behind
the rotary broom.
4. Set the speed by using the throttle lever. Do not
try to hold the rotary broom back or push it.
5. When sweeping dust, use a low brush speed (low
throttle).
6. When using the debris collector box, or the debris
shield, use a medium speed (half-throttle).
IMPORTANT: The brush pressure adjusts
automatically to the ground pro¿le. However, you
can inÀuence the brush pressure by either pulling
back or pushing on the handlebar. Pulling the
handlebar back decreases the pressure; pushing
will increase the pressure (for heavily soiled areas).
7. If the brush pressure is too heavy, the cleaning
effect is decreased because the brush ¿bers are
bent too much.

MAINTENANCE
TIRE PRESSURE
IMPORTANT: If the tire pressure is too low,
the inner tube will rub against the wheel and
be damaged. Over-inÀation can cause the tire
to burst. Check the tire pressure for both the
support and drive wheels regularly.
1. Lock the handlebar at the front-most setting.
2. Tip the rotary broom backward to rest on the
handlebar and the rear wheels. Have a second
person hold the rotary broom in this position.
3. Turn the wheel counterclockwise to expose the
valve stem.
4. InÀate the tire to 35 psi (2.5 bar), or for sweeping
rough surfaces, 30 psi (2 bar).
WARNING
Use safety glasses and gloves when inÀating
and installing the tires. Use manual pump
only to inÀate. Refer to the tire sidewall for
manufacturer's recommended pressure. Do
not exceed the maximum inÀation pressure.
