FIGURE 1
YOUR ATS 46/53 MACHINE HAS BEEN SHIPPED COMPLETE, BUT DO NOT ATTEMPT TO OPERATE
WITHOUT FOLLOWING THESE INSTRUCTIONS.
PREPARING THE MACHINE FOR OPERATION (IC Engine Powered)
1. Connect and tighten battery cables.
2. Fill the tank with REGULAR GRADE gasoline. (Diesel fuel if equipped with diesel engine.)
WARNING
Never fill the tank while the engine is running. Always be sure the gasoline container and sweeper are electrically connected before pouring gasoline. This can easily be done by providing an insulated wire (permanently
attached to container) with a battery clip on the other end.
3. Check engine crankcase oil level. Although properly lubricated at the factory, check before starting the
engine. No special break in oil is used and recommended number of operating hours before the initial oil
change is the same as normal. See Maintenance.
4. Check radiator coolant level. Permanent type antifreeze is added at the factory to provide protection to
approximately -35°F (37°C). To retain this protection level, always add ½ part water to ½ part antifreeze.
5. Check oil level in the hydraulic reservoir located at the center of the machine beside the engine. The oil
fill level should be halfway on sight glass. If oil is needed, add HYDRAULIC FLUID ONLY, automatic
transmission fluid FORD type “F.” After the first 50 operating hours, service must be performed on your
engine to ensure future high performance and trouble free operation. See Maintenance.
NOTE
After the first 50 operating hours, service must be performed on your engine to ensure
future high performance and trouble free operation. See Maintenance.

ADJUSTMENT
To lower the main broom, grasp the lever and move it to
the left out of the “UP” position, and place it in the
“SWEEP” or “FLOAT” position.
The “SWEEP” position is used for normal sweeping and
should be used under most sweeping conditions (approximately 2” broom pattern).
The “FLOAT” position is used for sweeping very uneven
surfaces only. Using the float position will cause premature
wear on the main broom if used under normal operating
conditions for extended periods of time (approximately 4”
broom pattern).
NOTE
The Main Broom will automatically engage when lowered to
the sweep position or the float position. The hopper must be
completely closed.

When the oil pressure drops below approximately 5 PSI an automatic protection circuit shuts
down the engine and illuminates the light to indicate low engine oil pressure. When this occurs,
have the machine serviced by a qualified service technician.
CHARGING SYSTEM LIGHT
The charging system light illuminates to indicate a charging system fault. When this occurs the
machines charging system is not working properly, have the machine serviced by a qualified
service technician.
CLOGGED FILTER LIGHT (Option)
The clogged filter light illuminates to indicate that the dust control filter is clogged. When this
occurs, stop the machine and use the filter shaker to clear the dirt and debris from the filter. After
using the filter shaker, continue sweeping.
HOPPER TEMPERATURE LIGHT (Option)
When the temperature of the air moving through the hopper dust control system exceeds 140° F,
an automatic protection feature shuts down the dust control fan and illuminates the hopper
temperature light. When this occurs, shut down the machine and carefully investigate for a
possible fire in the hopper, then manually reset the switch.
SOLUTION LOW LIGHT
The solution low warning light will illuminate when the solution tank is empty, indicating the end of
the scrubbing cycle.
RECOVERY HIGH LIGHT
The recovery high warning light will illuminate approximately 5 minutes before the recovery tank is
full, giving ample time to complete the scrubbing cycle, before the mechanical float shuts off the
vacuum to the recovery tank.

THE SCRUBBING SYSTEM - HOW IT WORKS
There are two scrubbing systems available for the ATS 46/53 machine, the non-recycling or standard scrubbing
system and the recycling or ESP scrubbing system.
THE NON-RECYCLING OR STANDARD SCRUBBING SYSTEM - HOW IT WORKS
During the scrubbing process, detergent solution water from the solution tank is fed to the solution line. There
it is fed to the floor where three disc scrubbing brushes work to dislodge soil.
After scrubbing, the dirty solution is vacuumed from the floor and discharged into the containment chamber in
the forward portion of the recovery tank, where a system of baffles helps to clarify the solution.
Sensors in each tank will indicate, by lights on the control panel, when the water in the solution tank is too low
or when the water in the recovery tank is too high.

American-Lincoln
ATS 46/53
ESP SYSTEM OPERATING INSTRUCTIONS
THE RECOVERY OR ESP AND AUTOFIL SYSTEM - HOW IT WORKS
During the scrubbing process, filtered water from the solution tank is fed to the solution line, where it combines
with detergent from the metering pump. This mixture is then fed to the floor where three disc scrubbing
brushes work to dislodge soil.
After scrubbing, the dirty solution is vacuumed from the floor and discharged into the recovery tank. At intervals, a float switch activates the recycling pump, which sends filtered solution from the recovery tank to the
solution tank. Detergent is added continuously to solution water from the flow valve.
The autofil system distributes water from the supply hose into the recovery and solution tanks. Then a solenoid valve is closed when the proper level in the solution tank is reached.

Both tanks must be drained and cleaned before filling.

The use of an extension cord with the charger should be avoided. Risk of fire and electrical shock is possible if
the wrong type or size extension cord is used. Locate all cords so they cannot be stepped on, tripped over, or
otherwise subjected to damage or stress.
GASOLINE-POWERED MACHINES
Machines to be stored over 30 days should be completely drained of fuel to prevent gum deposits from
forming on essential engine parts, fuel filter, and tank.
The use of a fuel additive, such as STA-BIL, or an equivalent, will minimize the formation of fuel gum deposits
during storage. Such an additive may be added to the gasoline in the fuel tank of the engine.
The following procedures should be used to prepare the machine for storage:
1. Remove all fuel from the tank. Run the engine until it stops from lack of fuel.
2. While the engine is still warm, drain oil from the crankcase. Refill with fresh oil.
3. Remove spark plug, pour approximately ½ ounce (15 grams) of engine oil into the cylinder and crank
slowly to distribute oil. Replace spark plug.
4. Store in a clean and dry area.
BATTERY-POWERED MACHINES
When batteries are not in use, they will discharge much sooner in cooler temperatures than in warm temperatures. Recharging and storing is more efficient at room temperature.
Do not discharge the batteries excessively (do not go below 80%). Excessive discharge can cause polarity
reversal of the individual cells in the battery. This will lead to complete failure of the batteries.
Use a hydrometer to monitor the specific gravity of the individual cells in the batteries. When checking the
specific gravity of the batteries, you should not see a large difference between the individual cells. The batteries
may need to be replaced if the battery shows a significant difference of specific gravity between the cells.

WARNING
Do not turn the steering wheel sharply when the machine is in motion. The machine is very responsive to
movement of the steering wheel. Do not make sudden turns. Scrub in straight paths. Do not bump posts. Do
not scrape the sides of the machine.
When the machine is in motion, do not push the directional/speed control pedal all the way forward. This is the
same as starting in “High” and will put a strain on the motor and drive system.
1. Plan your sweeping and scrubbing in advance. Try to arrange long runs with minimum stopping and start
ing. Sweep debris from narrow aisles out into main aisles ahead of time. Do an entire floor or section at
one time.
2. Pick up oversize debris before sweeping.
3. Allow a few inches of overlap of sweep and scrub paths. This will eliminate leaving dirty patches.
4. Do not turn steering wheel too sharply when the machine is in motion. The machine is very responsive to
movement of the steering wheel, so avoid sudden turns.
5. Try to follow as straight a path as possible. Avoid bumping into posts or scraping the sides of the machine.
6. When placing the machine in motion, avoid slamming the directional control pedal all the way forward
quickly. This is equivalent to starting in “High” and puts needless strain on the engine and drive system.
7. Always allow the machine to warm up before operating in cold temperatures.
8. Periodically turn the sweeping broom end-over-end to prevent the bristles from “setting” in one direction.
NOTE
Replace the sweeping broom when the bristles are worn to 3 inch (8cm) length. Replace disc brushes when
bristles are reduced to ½ inch (1.3 cm) in length. Replace squeegee rubbers when all usable edges have become
rounded with wear, impairing the wiping action.

SERVICE INSTRUCTIONS
SWEEPING SYSTEM SERVICE
MAIN BROOM
To prevent the broom from “setting” in one direction and to provide the maximum life of the broom it is recommended that the broom be turned end over end periodically.
CHECKING THE MAIN BROOM SWEEP PATTERN
Check the main broom sweep pattern after changing the broom or when poor sweeping performance is
encountered while sweeping.
1. While the machine is not moving, lower the main broom to the “SWEEP” position and let machine sweep
in
one spot for a short period of time.
2. Before moving the machine, raise main broom lever to the “UP” position and move the sweeper forward
enough to see the pattern left by the main broom bristles on the floor.
3. Check the width of the pattern on the floor to determine if the main broom requires adjustment.
-A normal sweep pattern left on the floor will be between 1 and 2 inches wide.
-A pattern that is more than 2 inches wide indicates the broom linkage needs to be adjusted “UP.”
-A pattern that is less than 1 inch wide indicates the broom linkage needs to be adjusted “DOWN.”
ADJUSTING THE MAIN BROOM HEIGHT
When changing the sweep height adjustment it is recommended that the bolt be adjusted 1 turn at a time.
After adjustment, recheck the sweep pattern to determine if further adjustment is necessary.
-Turn the adjustment knob counterclockwise to INCREASE the sweep pattern width.
-Turn the adjustment knob clockwise to DECREASE the sweep pattern width.
REPLACING THE MAIN BROOM
The Main Broom should be replaced when the bristles become worn to less than 2". The main broom is held in

HOPPER
The hopper houses the debris compartment, the dust control filter and the removable dust baffle. For maximum
performance and service life, keep the hopper clean and inspect the seals and flaps daily.
Clean the hopper prior to parking the sweeper at the end of the day. A clean hopper will make inspecting the
flaps and seals much easier and will prevent premature deterioration of hopper components. Do not leave the
hopper full of debris while in storage or when parked for extended periods of time
CLEANING THE HOPPER
Once the hopper has been emptied the insides of the hopper should be rinsed out with water.
CHECKING THE HOPPER SEALS
The hopper seals are important to positive dust control while sweeping. Damaged seals will reduce vacuum
pressure at the broom. Inspect for cuts, tears and proper positioning of the seal material. Replace all seals that
become damaged.
DUST CONTROL FILTER
The dust control filter should be checked daily for damage and cleaned if necessary. A damaged filter must be
replaced to prevent damage to other dust control system components. Inspect the filter for tears in the filter
media or excessive dirt lodged in the pleats. A tear in the filter media will allow dirt to pass through the filter and
can be easily seen as a dirty patch on the top side on the filter. Cleaning of the filter is necessary when the
filter shaker fails to adequately clean the pleats.
CHECKING THE DUST CONTROL FILTER
1. Park the machine on a smooth level surface, turn the key switch to the “O” position and engage the
parking brake.
2. Raise the hopper lid for access to the filter compartment.
3. Turn the filter latch, lift the filter frame and remove the filter.
4. Inspect the panel filter for tears and clean or replace if necessary.
5. Reinstall the filter, lower the filter frame and engage the filter latch.
6. Close the hopper cover.
CLEANING THE DUST CONTROL FILTER
Clean the dust control filter when the shaker fails to adequately clear the filter. The filter can be cleaned with
compressed air not to exceed 100 PSI.
To clean the filter with compressed air, apply the compressed air to the topside of the panel to backflush the
lodged dirt from the filter pleats. Be careful to not damage the filter media while cleaning.
The filter can be cleaned with a solution of soap and water. If this cleaning method is used do not use the filter
until it has completely dried.

CHECKING THE DUST FLAPS
The dust flaps are used on the wheel well, broom chamber and broom door. Inspect the flaps daily and replace
any flap that shows signs of wear or deterioration. All flaps should be replaced when worn or damaged to the
point that they can no longer perform their normal function. The adjustable flaps have slotted mounting holes
to facilitate adjustment.

AIR INTAKE SYSTEM
NOTE
Monitor the air filter indicator daily
The importance of replacing the air filter at the appropriate time cannot be overemphasized. Even a small amount
of dirt ingested through the air intake system will wear out a set of piston rings in just a few hours.
Always cover the air intake when removing the air filter for replacement. Keep all other air intake components,
such as hoses and clamps, secure and in good condition to prevent intake of unfiltered air.
AIR FILTER
The elements contained within this air filter are NOT reusable. There is no interim cleaning involved
other than a daily emptying of the dust collector housed in the filter cap. Squeeze and release the
rubber valve on the filter cap several times to expel any dust or dirt that has accumulated. Replace
BOTH the safety and main filter elements when the filter service indicator reaches the red band. The

COOLING SYSTEM
COOLANT LEVEL
Check the coolant level in the radiator daily, only when the engine is cool. Maintain the coolant level at approximately ¾ inches (1.9cm) below the filler neck seat on the radiator when the coolant is cool. Whenever coolant
level checks are made, check the condition of the radiator cap rubber seal. Make sure it is clean. Rinse off with
clean water if necessary. When replacing the cap on the radiator, also make sure the radiator filler neck is
clean.

P4404-1
FIGURE 49
WARNING
Never remove the radiator cap under any conditions while the engine is operating. Failure to follow these
instructions could result in damage to the cooling system or engine and/or personal injury. To avoid having
scalding hot coolant or steam blow out of the radiator, use extreme care when removing the cap from a hot
radiator. If possible, wait until the engine has cooled, then wrap a thick cloth around the radiator cap and turn it
slowly to the first stop. Step back while the pressure is released from the cooling system. When you are sure all
the pressure has been released, press down on the cap (still with a cloth) turn and remove it. Do not add coolant
to an engine that has become overheated until the engine cools. Adding coolant to an extremely hot engine can
result in a cracked block or cylinder head.
Use only a permanent type coolant that meets FORD specification ESE-M97B44-A such as FORD Cooling
System Fluid. Refer to the coolant chart on the container for additional antifreeze protection information. Do not
use alcohol or methanol antifreeze or mix them with the specified coolant. Plain water may be used in an
emergency, but replace it with the specified coolant as quickly as possible to avoid damage to the system.
With only water in the system, do not let the engine run hot.
RADIATOR
Inspect the exterior of the radiator for obstructions. Remove all bugs, dirt or foreign material with a soft brush or
cloth. Use care to avoid damaging the fins. If available, use compressed air or a stream of water in the opposite
direction to normal airflow. Open door for access. Check all hoses and connections for leaks. If any of the
hoses are cracked, frayed, or feel spongy, they should be replaced.
DRIVE BELTS
The drive belt(s) should be properly adjusted at all times. Loose drive belts cause improper alternator, fan and
water pump operation and overheating. Over tightening the belt may result in excessive wear on the alternator
and water pump bearings, as well as premature wear on the belt itself. Therefore, it is recommended that proper
belt tension be maintained.

when inspecting for gas leaks, or when LP tanks are present.
WARNING
Check all components for proper operation. Replace LP components when needed.
Never bypass defective safety components.
WARNING
Check routing of all LP hoses. Keep them away from sharp edges, exhaust manifolds, or other hot surfaces.
Check for signs of abrasion or deterioration.
WARNING
Check for gas odor before and during starting operations. If gas odor is noticed,
stop and check for leaks or component malfunction.
WARNING
Make sure the LP tank is free of dents or gouges.
WARNING
Keep the engine properly tuned.
WARNING
Make sure the LP tank is securely mounted on the machine with the retainer bracket
clamping the tank and with the locating pin in position.
WARNING
Make sure service coupling is clean and free of damage.
Make sure service coupling of tank matches machine servicing coupling.
WARNING
Park the machine in a shaded, cool area when not in use.
WARNING
Keep the LP tank service valve closed when the tank is not in use.
WARNING
Never overfill the LP tank. Fill the LP tank to the recommended weight stamped on the tank.
WARNING
Use care in handling LP tanks. Never drop or drag them.
WARNING
Always store and transport LP fuel tanks with the safety relief valve in the “UP” position.
WARNING
Avoid contact with the LP fuel to avoid frostbite.
WARNING
When the machine is to stand unused for a period of time (overnight), park it in a designated area.
Shut off the service valve at the tank and operate engine until the remaining fuel is consumed. Turn off key.

LP GAS COMPONENTS
LP FUEL SYSTEM
The LP fuel system consists of several components not found on the gasoline system. The LP fuel system also
contains the associated mounting hardware and plumbing for the LP components. The major LP components
are as follows:
1. Throttle plate & mixer
2. Combination water-heated vaporizer & regulator
3. LP fuel tank, valves & fittings
These components are factory set; attempts at adjusting these components should only be made by authorized
service personnel.

FIGURE 53
LP VAPOR WITHDRAWAL SYSTEM
The liquid fuel flows from the tank under its own pressure to the pressure relief valve. This valve is normally closed,
which prevents fuel from escaping into the atmosphere. When the engine is running, LP then flows through the
open fuel lock (lock automatically closes when engine is shut down) and into the vaporizer/regulator where it is
converted to a gaseous state. (The regulator reduces the tank pressure and makes the flow more constant.) The
LP is then piped into the mixer where it is introduced into the air flow and sent to the combustion chamber.
LP FUEL VAPORIZER-REGULATOR QUICK CHECK
Turn on the key switch and open the radiator cap. Check the coolant for bubbles. If bubbles are present, the
vaporizer may have a leaking gasket or may have developed a pinhole leak, allowing the LP fuel to enter the
cooling system.
LP CHECKLIST
This checklist can be performed quickly and should be done before every use. Be sure to make all necessary
checks as listed on the Maintenance Chart discussed earlier.
1. Check connections for leaks.
2. Open the LP storage tank valve.
3. Check the regulator. Momentarily press the fuel primer on the regulator cover to bleed air out of the
system.
4. Start the machine’s engine.

LP TANK COMPONENTS
LP FUEL TANKS
The LP tank is located under the driver’s seat. Use only the proper size and type of LP tank. The ATS 46/53 LP
powered sweeper/scrubber uses a 33.5 lb. Liquid withdraw tank. The DOT designation of the tank is DOT 4BW240. Standard D.O.T. LP fuel tank sizes have 14, 20, 33.5, and 43.5 pound capacities. The liquid volume
permitted in these containers is less than the total volume of the cylinder. This provides for expansion of the LP
fuel in the case of a temperature increase above the normal amount. Excessive heat may cause the fuel to
expand too much, causing the safety relief valve to vent some LP fuel, relieving internal tank pressure.
Each tank is marked showing the type of construction (liquid or vapor), the manufacturer, the date of manufacture, the capacity, the weight, and the date of requalification. D.O.T. fuel tanks must be requalified (checked)
periodically. This requalification must be recorded and maintained for the life of the container.
LP fuel tanks are equipped with the following approved valves and fittings:
* Safety Relief Valve - This is a spring-loaded valve that relieves excessive pressures which may develop in
the tank due to unusual conditions.
* Liquid Service Valve - Liquid is withdrawn from the tank through this valve. The LP tank may be filled
through this valve if the tank is not equipped with a filter valve.
* Excessive Flow Valve - This valve is part of the liquid service valve. It is mounted inside the tank and
prevents LP fuel from leaving the LP tank in the event of accidental breakage of external fittings or hoses.
* Filler Valve - This valve is optional. If this valve is not present, the tank is filled through the service valve.
* Liquid Level Gauge - This gauge is optional.

LP TANK CARE
USE AND CARE OF LP TANKS
If an LP tank is damaged or leaking, it should be immediately removed to a designated safe area and the proper
personnel should be notified. Do not attempt to make repairs to the cylinder regardless of its condition. Repairs
must be made by qualified personnel.
The care an LP tank receives has a direct bearing on how long the tank can be used safely. LP tanks must not
be dropped, dragged, or slid across any surface. To move the LP tank, use a hand truck or roll the tank on its
foot ring while it is being held in a position slightly off the vertical.
CHANGING LP TANKS
Refueling machines with LP tanks is an important process. Refueling is accomplished by replacing the empty
LP tank with a full tank.
The tank changing operation presents an opportunity for the machine operator to carefully inspect the tank, tank
fittings, the fuel lines and fuel line fittings. If abnormal wear is detected, the operator should report these findings
to the appropriate personnel for immediate action.
CHANGING THE LP TANK
1. Park the machine in a designated safe area and set the parking brake.
2. Close the tank valve.
3. Remove the quick-disconnect coupling from the tank valve.
4. Inspect the machine’s fuel lines and the quick-disconnect coupling for damage or abnormal wear.
5. Remove the empty tank from the holding device.
6. Inspect the tank and tank fittings for damage or abnormal wear. Handle the tank carefully. It must not be
dropped or mishandled.
7. Store the LP tank in a designated safe area.
8. Select a full LP tank and observe for damage or leaks.
9. Carefully install the full tank in the machine so the tank-centering pin enters the aligning hole in the tank
collar. This assures that the tank is positioned properly and allows for proper operation of the safety relief
valve, liquid level gauge, and service valves.
10. Fasten the tank-retaining bracket so the tank is locked into position.
11. Reconnect the fuel line to the tank-servicing coupling.
12. Open the service valve slowly and check for leaks. If a leak is found, close the valve immediately and
notify the appropriate personnel.
13. If no leaks are detected, the engine is ready to start. Do not start the engine unless the operator is in
position with the directional control pedal in the neutral position.
STORING LP FUEL TANKS
Whether the storage is inside or outside, the LP tanks should not be in the vicinity of combustible materials or
high temperature sources such as ovens or furnaces. This may cause the heat to raise the pressure of the
fuel to a point where the safety relief valves would begin operation. Care should be taken to ensure that the
cylinders are stored in such a manner that if the safety relief valves are triggered, the vapor will be relieved rather
than any liquid.
Valves on empty tanks must be closed during storage and transportation.
