MACHINE INFORMATION/PREPARATION
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 traffic.
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 tow-
hitch or three-point linkage. Tow the scrubber from the front using the tow-hitch fitted 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 flatbed 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.
WARNING
Do not hook or connect chains around the front axle transmission shaft,
power steering cylinders, front axle, or other parts of the scrubber that could be damaged
by the chains or excessive strain during transport.

MACHINE INFORMATION/PREPARATION
MACHINE PREPARATION
YOUR AMERCAN-LINCOLN SR9772 HAS BEEN SHIPPED COMPLETE, BUT DO NOT ATTEMPT TO
OPERATE WITHOUT READING THE FOLLOWING INSTRUCTIONS:
1. Fill tank with diesel fuel only
WARNING
Never fill fuel tank while the engine is running.
2. Check engine crankcase oil level. Although properly lubricated at factory, check before starting engine. No special break-in oil
is used and recommended number of operating hours before the initial oil change is 50 hours. See lubrication and maintenance
section of the New Holland manual.
3. Check radiator coolant level. Permanent type antifreeze is added at the factory to provide protection to approximately -35ºF. To
retain this protection level, always add ½ part water to ½ part anti-freeze.
4. In addition to regular service operations listed, the following items should be checked every 10 hours or daily during the first 50
hours of operation.
-Engine Oil Level
-Rear Axle Oil Level (at turbine cover access)

SCRUBBER OPERATION
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 filter and levels on the oil, coolant, hydraulic fluid 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 fitted 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 slow-
moving 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 first 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 fires 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).

American-Lincoln 1-13
SR9772
SCRUBBER OPERATION
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 five 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 parrafin components in the diesel fuel which leads
to a reduction in fluidity 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 first, 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 parrafin 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.
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).

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 floor 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 floor surface, through the squeegee tools
and a recovery tank air/water separation system. A float 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
HOW IT WORKS (with Camel System)
During the scrubbing process, filtered 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 floor where four disc scrubbing brushes aggressively work to
dislodge dirt and grime.
After scrubbing, the used solution is vacuumed from the floor and discharged into the containment chamber of the recovery tank.
Once there, a system of baffles 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 filtered 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.
