BASIC POWERBOSS® SAFETY
PowerBoss® sweepers should never be operated
unless:
1. The operator is trained and authorized to
operate the equipment and,
2. The equipment is free of malfunctions.
Malfunctioning equipment should be removed
from service.
DANGER
Keep cigarettes, matches and all other ame
sources away from the sweeper. Gasoline, LP
gas and diesel fuel are highly ammable. Lead
acid batteries are equally dangerous due to the
highly explosive hydrogen gas they emit.
WARNING
Before starting the engine, make sure that:
* You are securely seated in the operator’s
seat.
* The parking brake is locked.
* The directional control pedal is in neutral.
* The throttle is in idle.
* Hydraulic controls are in the OFF position.
WARNING
During operation:
* Keep your hands and body clear of moving
parts, especially when the hopper or lift arms
are partially or fully raised.
* Make sure others in the area stay clear of the
equipment and moving parts.
* Never attempt to dump debris from a dock or
mezzanine. Dump from ground level only.
WARNING
When leaving the sweeper unattended:
* Place the controls in the OFF position.
* Set the parking brake.
* Shut off the engine.
WARNING
During cleaning and maintenance:
* Always stop the engine and set the parking
brake before servicing.
* Never use detergents or cleansers that are
ammable or combustible.
* Never inate a pneumatic tire without using a
safety cage.
* Do not attempt any impeller adjustment
unless you have shut off the engine. Never
place your hands near the intake hoses or
inlet when the engine is running.
* Always engage the safety arm before
servicing the hopper. Do not rely on the
hydraulic cylinder to keep the hopper raised.
* Never test for hydraulic hose leaks using
your hand or any other part of your body.
High pressure leaks can be very dangerous
and should only be checked using a piece or
paper.
WARNING
When servicing or repairing the fuel system:
* Work in a properly ventilated area, do not
smoke or allow an open ame near the fuel
system.
* Never bypass safety components unless you
are testing them.
* Never bypass the fuel lter lock, except when
testing them (and always reconnect them
after testing).
* Wear gloves to disconnect the tank coupling.

WARNING
Do not operate an LPG powered sweeper
when any component in the fuel system is
malfunctioning or leaking.
WARNING
Replace any defective safety components
before operating the sweeper.
CAUTION
Do not drive with the hopper in the raised
position except the few feet necessary to
position the hopper over the dumpster or
receptacle. Driving with the hopper raised
reduces visibility and creates conditions
for striking over-head objects, throwing the
machine off-balance and other hazards.
CAUTION
Travel slowly on grades.
CAUTION
Place a block or chock behind the wheels when
parking on inclines.
CAUTION
Use special care when traveling on wet
surfaces.
CAUTION
Observe all proper procedures for operation and
maintenance of the sweeper, as outlined in this
manual.
CAUTION
Remain alert at all times to people and
equipment in and around your area of operation.
ATTENTION!
Do not operate the #2 RTR lever before the #1
light illuminates.
ATTENTION!
Never push or tow a machine faster than 6 mph.
ATTENTION!
Engage tow valve before towing or pushing.

TROUBLESHOOTING PROCEDURES
AIR INTAKE SYSTEM
Check Air Filter Service Indicator
The air lter service indicator shows when to
change the air lter element. Check the indicator
on a daily basis. The red indicator gradually
becomes visible as the air lter elements load
with dirt. It is not necessary to change the air lter
elements until the red indicator reaches the top of
the service indicator and locks into position.
1. Lift engine cover.
2. Inspect air lter service indicator
NOTE: The indicator may return to the nonviable
position when the engine is shut off. To
check, reset indicator and turn on the

WARNING
Never attempt to perform any service on the
equipment or components until the engine is
OFF, the parking brake is LOCKED, and the
wheels are CHOCKED.
WARNING
Never operate an LPG powered sweeper
when any component in the fuel system is
malfunctioning or leaking.
WARNING
Never bypass safety components unless you
are testing them.
WARNING
Replace any defective safety components
before operation the sweeper.
WARNING
During repair or servicing of the fuel system,
work in a properly ventilated area and do not
smoke or allow an open ame near the fuel
system.
WARNING
When disconnecting the tank coupling, always
wear gloves. LPG fuel can freeze bare hands.
WARNING

Blowing Out Radiator Fins
NOTE: Make sure radiator is cool before
blowing out the radiator ns with
compressed air.
Reverse Flow Flushing
1. At the engine, disconnect the hoses.
2. Make sure the radiator cap is on tight.
3. Using a hose clamp, attach a ushing gun
onto the lower hose.
4. Turn on the water and ll the radiator.
5. To keep from damaging the radiator, apply air
pressure slowly and carefully.
6. Shut off the air pressure, rell the radiator
