TOWING THE SCRUBBER

NOTE: The scrubber must only be towed for short distances. For example, from inside a building to the outside. It must never be towed for long distances on the road in heavy trafﬁ c.

NOTE: To transport the scrubber, load it, complete with its four tires, onto a truck.

Should it be necessary to tow the scrubber, use a strong chain. Tow the scrubber from the rear using only the drawbar, the rear towhitch or three-point linkage. Tow the scrubber from the front using the tow-hitch ﬁ tted to the front support or ballast. THE SCRUBBER MUST BE TOWED WITH A DRIVER ON BOARD TO STEER AND STOP THE SCRUBBER WHEN NECESSARY.

To avoid damaging the transmission or other components which turn but are not lubricated during towing, observe the following:

1. Only tow for short distances

2. Do not exceed 5 mph (8 km/h)

3. If possible, run the engine to lubricate the power steering components

4. Position the gear and range levers in neutral

CAUTION

Never use ropes or cables to tow the scrubber.

These may slip or break, presenting the risk of serious injury.

CAUTION

Never exceed 5 mph (8 km/h) when towing.

Effort to control steering is much greater and response much slower.

LOADING THE SCRUBBER ON A TRANSPORTER

Load the scrubber with all four wheels on the truck platform or ﬂ atbed trailer.

Secure the scrubber to the transporter with suitable chains.

Secure the front of the scrubber using the towing hitch; secure the rear using the tow bar or tow bar supports.

SCRUBBER OPERATION

https://harrissupplyind.com - To Order Parts Call 608-268-8080

CHECKS BEFORE USING THE SCRUBBER

Before using the scrubber, make sure you are familiar with the position and function of all controls. Ensure the maintenance and lubrication operations described in the NEW HOLLAND manual have been carried out, followed by a visual inspection of the outside of the scrubber. Give particular attention to the following:

1. Check the air ﬁ lter and levels on the oil, coolant, hydraulic ﬂ uid and fuel.

2. Signs of leaks or damaged components connected to pressure tubes, sleeves and connectors.

3. Signs of cracking on the fanbelt.

4. Accumulation of foreign matter or leaks around the engine and hydraulic pump and related hoses.

5. Loose fasteners.

Always complete any necessary repairs before using the scrubber.

SAFETY COVERS

The scrubber is ﬁ tted with covers designed for the personal safety of the operator and others when in use. The BONNET covers the moving parts of the engine and must be closed before starting. The fan has COVERS on both the left and right sides.

CAUTION

Before starting the engine or using the scrubber, always make sure all safety covers, panels and access doors are securely closed.

Before starting the engine or moving the scrubber, follow these instructions:

1. Do not start or operate the scrubber in an enclosed area.

2. Before starting the engine, make sure all controls are in neutral and the parking brake is set.

3. Operate controls from driver’s position only.

4. Stop engine before performing any service or maintenance operations.

5. Use the steps provided for entering and exiting the scrubber.

6. When driving on roads, indicate all intentions to stop, turn or slow down; use appropriate warning devices to indicate a slowmoving vehicle.

CAUTION

When SHIFTING from one range to another, forward to reverse, or reverse to forward, the operator MUST reduce the speed (throttle) to LOW IDLE, shift range and/or gear, then increase the speed (throttle).

STARTING THE ENGINE

1. If the scrubber has not been used for some time, or is being started for the ﬁ rst time in low outside

temperature conditions, operate the fuel pump starting lever approximately 20 times.

2. Press down the clutch pedal, place the shuttle control lever in neutral to close the starting safety device switch.

3. Move the throttle lever to approximately the halfway position.

4. Turn the starter key and release as soon as the engine starts.

STARTING IN LOW OUTSIDE TEMPERATURES

When the outside temperature is low and the engine cold, cover the radiator before starting so the engine coolant can quickly reach the correct temperature, then remove the cover. To avoid running down the battery, any single attempt to start the engine should last no longer than 15 seconds. If, however, the engine ﬁ res but does not start, continue attempt for up to 30 seconds. Wait at least one minute between each attempt to start the engine. To avoid excessive depletion of battery, make no more than six attempts at starting.

STARTER KEY SWITCH

The following three positions appear on this switch:

A -No power supply to any of the circuits (key can be removed); engine stops - injection shutoff activates automatically.

B -Standby for engine start-up; indicator and control instruments ON.

C -Engine start-up (when released, key automatically returns to position B).

12 - FORM NO. 56041803 SR9772

Page 13

SCRUBBER OPERATION

https://harrissupplyind.com - To Order Parts Call 608-268-8080

STARTING WITH THE THERMOSTART

Carry out pre-start operations as previously described; turn starter switch key to position B (stand-by); turn on the thermostart by pressing pushbutton and hold for 25 seconds; move starter switch key to position C while holding down the thermostart button until engine starts. Once the engine has started, release both the key and thermostart button. If after two or three attempts the engine has not started and black smoke is coming from the exhaust, start engine without using the thermostart.

CAUTION

When starting the engine after an extended period of non-use, avoid using the hydraulic system immediately since all moving parts will require lubrication before they are subjected to full load. Especially when the outside temperature approaches 0º C (32º F), run the engine at 1300-1500 rpm for approximately ﬁ ve minutes to heat the rear transmission oil to working temperature.

CAUTION

If any warning lights illuminate to signal a fault, check and repair the faulty part. If the warning light continues to signal a fault, have the scrubber checked by your NEW HOLLAND dealer.

CAUTION

When the outside temperature is below 0º C, in order to prevent separation of the parraﬁ n components in the diesel fuel which leads to a reduction in ﬂ uidity and subsequent fuel supply problems, mix the diesel fuel with antifreeze (or similar product) in the proportions described on the container. Put the antifreeze in the tank ﬁ rst, followed by the fuel. The antifreeze will ensure there is optimum fuel supply to the engine without reducing performance (up to -20º C/-68º F). The diesel must be mixed with the antifreeze before any sign of parraﬁ n separation - adding it later will have no effect on the engine if the cold has already caused it to stop running or prevented it from starting.

TO DRIVE MACHINE (FOR TRANSPORT)

Follow these steps to drive (transport) the machine to the area to be cleaned.

1. Be sure the scrub brushes and the squeegee are in the “up” position with all other controls in the “OFF” position.

2. Release the parking brake.

3. Depress the clutch and move the gear and range levers to desired positions, slowly release clutch while depressing accelerator.

4. To stop, reduce speed, depress clutch and apply brakes. When scrubber is stationary, reduce to low idle, move range and

gearshift levers into neutral, release the clutch and set the parking brake.

THE SCRUBBING SYSTEMS

https://harrissupplyind.com - To Order Parts Call 608-268-8080

HOW IT WORKS (Without Camel System)

During the scrubbing process, a solution of detergent and water from the solution tanks is fed through the solution lines where it is disbursed to the ﬂ oor through the four scrubbing brushes that aggressively work to dislodge dirt and grime.

As the machine moves forward, the solution vacuum system lifts dirty water and debris from ﬂ oor surface, through the squeegee tools and a recovery tank air/water separation system. A ﬂ oat switch in the tank activates an indicator light on the control panel when the water level in the tank becomes too high. Debris and sludge settle to the bottom of the recovery tank.

THE SCRUBBING SYSTEMS

https://harrissupplyind.com - To Order Parts Call 608-268-8080

HOW IT WORKS (with Camel System)

During the scrubbing process, ﬁ ltered water from the solution tank is fed through the solution lines where it combines with the detergent from the metering pumps. This mixture is then fed to the ﬂ oor where four disc scrubbing brushes aggressively work to dislodge dirt and grime.

After scrubbing, the used solution is vacuumed from the ﬂ oor and discharged into the containment chamber of the recovery tank. Once there, a system of bafﬂ es helps to clarify the solution on its way to the pumping chamber of the recovery tank. At intervals, a system of sensors activates the recycling pump which sends ﬁ ltered solution from the pumping chamber on its way to the centrifugal separator which further aids clarifying of the solution for re-use. In the separator, solids are removed and purged into the containment chamber. The solids-free solution is then fed up through the separator outlet and into the solution tank where it is ready to be mixed with fresh, metered detergent, allowing the cleaning process to continue.

BRUSH PRESSURE AND BRUSH WEAR

Factors affecting brush wear are type of bristle, bristle, area, and load on the bristles. See your authorized distributor for the type of brush and bristle most suitable.

Brush pressure may be adjusted by adding or removing counterbalance springs. The counterbalance springs are located on the underside of the tractor foot rest.

The pressure will vary as follows:

No. of Springs Pressure per Brush

0 353.8 lbs. 1 315 lbs. 2 291.4 lbs. 3 272 lbs. 4 252 lbs.

Adding springs will decrease scrub brush load. Shorter brush life can be expected as the scrub brush pressure is increased.

REAR SQUEEGEE

The squeegee will require service when the inner edges of the blades become round with wear, impairing the wiping action or water pickup. To service the rear squeegee use the following steps:

1. Loosen the aluminum knobs ( these hold the squeegee tool to the squeegee support).

2. Remove the squeegee tool and turn upside down to service the blades or caster wheels. The squeegee blades are designed to ﬂ ip over and use another unworn edge.

To service the blades:

1. Loosen the clamp bolts.

2. Loosen far enough to slip the end clamp brackets off the squeegee tool. This will allow ﬂ ipping the blades or installing new blades.

3. Install blades so that outer blade is 3/16” longer than inner blades by assembling the top edge of the blade against the squeegee tool weldment.

4. Reinstall squeegee clamp band and tighten clamp bolt tight.

VACUUM RELIEF VALVE

The vacuum manifold inlet system is equipped with a factory-adjusted relief valve which limits the pressure produced by the solution vacuum at 90 - 95” of water.

CAUTION

Continuous operation at vacuum pressures exceeding 95” of water will cause excessive heat in the turbine resulting in turbine failure.

The relief valve is located on top of the recovery tank and is part of the air inlet system for the solution vacuum.

To check the factory setting:

1. Remove the squeegee suction hoses from the recovery tank pick-up hoses.

2. Cover inlet pipe (must be air-tight seal).

3. Run engine at 2000 rpm.

4. Place vacuum gauge on other inlet pipe and check reading.

To adjust relief valve setting:
