HOPPER FILTER COVER
(See Figure 29)
The hopper filter cover is actually the front cover or “hood”
of the machine. It opens forward by releasing latches to
access the filter compartment for service/inspection of the
dust control filter and optional hopper temp sensor.
Inspect gaskets daily. Replace any gaskets that show
signs of deterioration. Failure to maintain the gaskets in
serviceable condition will degrade dust control at the floor
and will result in less than optimal sweeping performance.

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.

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 inter-
vals, 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.
NOTE
Both tanks must be drained and cleaned before filling.

14. Move the hopper dump door lever to the “OPEN” position until the dump door opens.
WARNING
Do not turn off the machine with the hopper in the lifted position.
NOTE
After stopping the machine, perform these post-operation checks.
POST-OPERATION CHECKLIST
1. Clean the debris hopper.
2. Check sweeping brooms for wear or damage.
3. Check all flaps for wear, damage and adjustment.
4. Check all systems for leaks.
5. Charge and service motive power batteries (see battery charging instructions).
6. Check squeegees for damage.
BATTERY CHARGING INSTRUCTIONS
Charge the batteries at the end of each day or when the battery condition meter indicates low battery voltage.
The batteries need to be charged when the needle stays in the “red” zone while the machine is being operated.
When charging the batteries, only use the quick disconnect provided to ensure correct polarity. Follow the
instructions below.
Check the liquid level in the batteries at least once a week and add water when low. Use only distilled water.
Fill the batteries after charging them to prevent electrolyte from spilling over onto the tops of the batteries
during the charging process.
WARNING
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.
STORAGE FOR BATTERY-POWERED MACHINES
When batteries are not in use, they will discharge much sooner in cooler temperatures than in warm tempera-
tures. 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.

FIGURE 35
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 foot pedal all the way down. This will put a strain on drive
system.
1. Plan your sweeping and scrubbing in advance. Try to arrange long runs with minimum stopping and
starting. 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.

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 recom-
mended 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 encoun-
tered 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
place by the right side broom door. This feature provides for easy removal and installation of the main broom
without the need for special tools or equipment. Follow the instructions below for main broom removal &
replacement.
1. Park sweeper on a smooth level surface, engage parking brake, turn key switch to “O”, place the main
broom lever in the “SWEEP” position.
2. Lift the door latch to open the right side broom door.
3. Swing the broom drive idler hub out to clear the main broom.
4. Remove the broom from the broom compartment.
5. Install the replacement broom. Pay special attention to the slots on the broom, it may be necessary to
rotate the broom so the tabs on the drive hub align with the slots on the broom.
6. Swing the idler hub to engage the main broom and close the access door. Check the door latch for proper
engagement when closed.
7. Check the Main Broom sweep pattern and adjust as necessary.
MAIN BROOM LEVEL ADJUSTMENT
The main broom level is factory set and should not need adjustment. If the level becomes out of adjustment and
the broom bristle contact pattern is not an even 1" to 2" wide, the broom arm lift frame will need to be adjusted.
The frame is supported by two plates located inside the broom doors. The carriage bolts that secure the plates
to the frame will need to be loosened. The frame can then be leveled and the bolts re-tightened.

FIGURE 37
WARNING
The hopper could fall and cause serious injury.
Always engage the hopper safety arm before working under the hopper.
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 inside 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.

DUST FLAPS
The dust flaps are very important to sweeping and dust control and are susceptible to damage and should be
inspected daily and maintained in good condition.
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.
ADJUSTING THE DUST FLAPS
Adjust the flaps so there is a 1/8" to 1/16" gap between the floor and the bottom edge of the flaps. The rear
flap adjustment is 1/16" (16 cm.) above the floor.
1. Park the machine on a smooth level surface and engage the parking brake.
2. Loosen the flap retaining screws and adjust the flap to clear the floor and leave a 1/16" to 1/8" gap.
3. Tighten flap-retaining screws while holding flap in position.
4. Drive the machine on a smooth surface and recheck the flaps for proper floor clearance.

If the system fails to operate, consult the Electrical Troubleshooting Guide.
SOLUTION CONTROL (Non-Recycling or Standard)
The solution control lever controls the amount of solution applied to the scrubbing brushes.
The solution control should shut off completely with the lever in the (front) “off” position. If complete shut off
does not occur, the control valve should be adjusted.
SOLUTION CONTROL (Recycling or ESP System)
In the recycling mode, the solution control lever is also used to activate the detergent pump. If the detergent
pump fails to operate (engine running) when the solution control lever is moved into the low to high range, first
check the circuit by manually activating the switch. If the detergent pump does not operate at this time, a
further electrical or mechanical check is required (see Electrical Troubleshooting Guide or Detergent Pump
Troubleshooting).

GENERAL MACHINE MAINTENANCE
RECYCLING PUMP ESP SYSTEM
The recycling pump is located under the seat. The pump is electric and except for daily cleaning of the pump
intake screens, it requires no regular maintenance.
RECYCLING PUMP STORAGE
Always drain pump for extended storage, especially when freezing temperatures may be encountered.
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 four aluminum knobs (item 10, 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 flip over and use another unworn edge (items 5 & 6).
To service the blades
1. Loosen the clamp bolts which clamp items 8 & 9 together.
2. Loosen far enough to slip the end clamp brackets off the squeegee tool. This will allow flipping the blades
or installing new blades.
3. Install blades so that the outer blade is 3/16” longer than the inner blades. This is achieved by assembling
the top edge of the blade against the squeegee tool weldment.
4. Re-install the squeegee clamp band and tighten the clamp bolt.
SQUEEGEE CASTER WHEELS
There are 2 grease fittings on each caster wheel. The casters should be greased each time the blades are
serviced.

BATTERY
The battery is located in front of the operator’s compartment with easy access through the hopper door.
Keep the top of the battery clean and dry. Keep the terminals and connectors clean. To clean the top of the
battery, use a damp cloth with a weak solution of ammonia or bicarbonate of soda. To clean the terminals and
connectors, use a terminal and connector-cleaning tool.
WARNING
NEVER allow the soda solution to enter the cells.
This will permanently destroy the battery’s recharging capabilities.
