SAFETY INFORMATION

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.

Page 18

Armadillo 6X and AM7D-III PB# 4100043UM Rev. A 08/14

SAFETY INFORMATION

WARNING

When leaving the sweeper unattended:

* Place the controls in the OFF position.

* Set the parking brake.

* Shut off the engine.

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

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.

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.

Floor Clearance and Dump Angle Adjustment

NOTE: In order to perform properly, the hopper must

maintain a distance of 3½” (8.89 cm) from the oor to the rear hopper entrance lip. The front of the hopper should be adjusted so that the front bumper aligns with the hopper frame where the two meet. When properly adjusted, the front edge of the hopper will be 5” (12.7 cm) to 6” (15.24 cm) from the oor.

1. Park the machine on a level surface, shut off the engine and engage the parking brake.

WARNING

Do not rely upon the hydraulic cylinders to keep the hopper raised for maintenance. Always engage the safety arm before servicing the hopper.

2. Adjust the lift arm stop bolts located on top of the wheel wells as low as possible while still allowing the side broom assembly to clear the lift arms when the hopper is in the NORMAL position. Be sure that both lift arms contact the stop bolts at the same time.

HYDRAULIC MANIFOLD SOLENOIDS

The curb broom, main broom, main broom lift, and impeller are activated when certain solenoids are energized. Solenoids are remotely signaled by pushing the desired switch on the control panel. When troubleshooting the electro-hydraulic system, it is important to determine if the problem is electrical or mechanical. The electrical side should be eliminated rst. When a function is summoned, the corresponding solenoid is energized and emit a magnetic eld. A small steel washer will stick to an energized coil. Be sure that only the required solenoid is energized. If the solenoid is correct, the problem is mechanical.
