٭

You have read and understand the operation

manual.

٭

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.

2. During operation:

٭

Keep your hands and body clear of moving

parts, expecially 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.

3. When leaving the sweeper unattended:

SAFETY (Continued)

4. During cleaning and maintenance:

٭

Always stop the engine and set the parking

brake before servicing.

٭

Never use detergents or cleansers that are

flammable or combustible.

٭

Never inflate 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.

5. When servicing or repairing the fuel system:

٭

Work in a properly ventilated area, do not smoke

or allow an open flame near the fuel system.

٭

Never bypass safety components unless you are

testing them.

٭

Never bypass the fuel filter lock, except when

testing them (and always reconnect them after

testing).

٭

Wear gloves to disconnect the LPG tank

coupling.

6. Do not operate an LPG powered sweeper when any

component in the fuel system is malfunctioning or

leaking.

7. Replace any defective safety components before

operating the sweeper.

1. 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.

The Power of Clean

Never use detergents or cleaners that are flammable or

combustible. Always wear safety glasses when using

chemicals of any kind.

This machine is designed so that the scrub brushes will not

turn and solution will not be delivered to the brushes while

the machine is not moving.

To operate the scrub brushes, follow these steps:

1. Lower the scrubheads to the floor with the scrubhead

switch. This will lower the scrubhead and turn the

brushes on when the machine begins to move.

2. The scrubhead will apply the selected pressure to the

brushes.

3. To select the proper brush pressure for conditions,

locate the brush pressure selection knob on the left

console. There are four (4) selections. The lightest

pressure is applied with the knob turned to the left, the

heaviest to the right. Once set, it is not necessary to

change this knob as the scrubhead is raised and

lowered. Each time the brushes are activated, the

scrubhead will return to the setting selected.

For normal scrubbing, the main broom and side broom

remain off.

To sweep simultaneously, lower the brooms at this time.

4. When the scrubhead is lowered and the machine is

moved forward or reversed, solution will automatically

begin to flow. To select the rate of solution flow, locate

the solution control knob on the left console. If turned

completely to the left, no solution will flow. Rotating the

knob to the right will increase the flow through three (3)

more settings. It is not necessary to change this knob as

the scrubhead is raised or lowered. When the

scrubhead is raised, solution flow automatically stops.

When the scrubhead is lowered and the machine is

moved, solution flow resumes at the selected rate.

5. Lower the squeegee with the squeegee switch. The

squeegee can also be raised with the same switch.

Lowering the squeegee activates the scrubbing impeller

automatically. When the squeegee is raised, the

impeller will continue to run for ten (10) seconds before

shutting off.

When machine travel stops, the scrub brushes stop rotating

and solution flow is interrupted until travel resumes. This

prevents flooding the floor and prevents excessive brush

wear and floor damage.

6. Drive forward slowly.

Use care when driving on wet surfaces.

Always travel slowly on grades.

For double scrubbing, proceed as follows:

1. Follow the procedures on the previous page for

scrubbing without lowering the squeegee to the floor

and with the sweeping brooms off.

2. Make multiple passes over the same area of the floor as

conditions dictate.

3. Lower the squeegee with the squeegee switch for the

final pass. The squeegee can be raised with the same

switch.

HIGH DUMP

MODELS

ROTARY TRASH

RELOCATOR

(RTR™)

The lever on the front control panel is used to raise the

hopper to a height up to 60” (1.52 m) and dump it.

The lever is spring loaded to a center OFF position.

•

To raise the hopper, pull back the lever to the RAISE

position and hold until the hopper raises to the proper

height for the dumpster or container.

•

To empty debris, locate the dump door/filter shaker

switch at the left side of the instrument panel.

•

Press and hold the left side of the switch until the dump

door has opened.

•

To lower the hopper, push the lever forward to the

LOWER position until the hopper stops.

The dump door will remain open until the hopper has been

completely lowered.

Rotary Trash Relocator (RTR™) is a standard feature on

this machine. Its purpose is to increase the holding capacity

of the debris hopper to make dumping the hopper less

frequently required. Each time the main broom is turned off,

the dump door closes automatically. This action relocates

the debris to the front of the hopper.

ADJUSTMENT

REMOVING SIDE

SQUEEGEE

REPLACING THE

SIDE SQUEEGEE

RUBBER

If the yellow “Check Engine Light” illuminates, this indicates

that the engine has experienced a fault. Contact your

service provider and advise them of the indicator light.

Most hydraulic functions are controlled by three hydraulic

manifold blocks containing electronically controlled valves.

These manifold blocks are located behind the hopper and

can be accessed by raising the hopper and engaging the

safety arm.

The manifold blocks can also be unbolted from the frame

and tilted forward for easier servicing.

There are two adjustments for the side squeegee. The first

is the pitch adjustment which controls making the rubber

edger parallel to the floor surface. This is controlled by the

knob on the leading (forward on machine) end of squeegee

tool. By rotating clockwise the front (forward) end of the

rubber will be raised. Turning the knob counterclockwise

will lower the front edge. The second adjustment is the

spring alignment. By adjusting the spring anchor pin to

stretch the spring tighten, more pressure will be applied to

the rubber producing a more aggressive contact with the

floor. Greater force may be modified for rough, pitted floor.

Smooth floor requires less pressure.

To replace the rubber parts, simply remove the side

squeegee assemblies from the machine by attaching the

handle on top of the scrubhead. When sweeping only along

the edge, walls or shelving, remove the side squeegees

and right side brush to make side broom use easier.

The long rubber components are 4-sided squeegees. Two

edges may be used on the right side of the machine and

then transferred to the left side of the machine for using the

other two edges. Both sides use the same rubber

components. Because of its unique shape, the short rubber

parts are 2 sided. When one edge is worn, it may be

transferred to the opposite side of the machine to use the

other edge. The longest edge must always make contact

with the floor.

CAUTION

Do not leave the hopper in the RAISE position for an

extended period of time.
