The solution tank fill (3) is located at the left rear corner of the machine and has a 75 gallon
(284 liter) maximum capacity. Fill the tank with the proper dilution of cleaning chemical
mixed with water according to the manufacturer’s recommendations. If using a powdered
chemical, mix it with water in a bucket before putting it into the machine’s solution tank.
NOTE: DO NOT fill the tank past the Maximum Level on the Water Level Gauge (24).
CAUTION!
Use only low-sudsing, non-flammable, non-caustic cleaning chemicals intended for machine application.
This is a rider-type automatic floor sweeping and scrubbing machine. It is designed to sweep up debris, lay down cleaning solution, scrub the floor, and vacuum dry all
in one pass. The sweeping and scrubbing operations can also be performed separately.
The controls were designed with one touch operation in mind. For single pass scrubbing the user can simply depress one switch and all scrub functions on the machine
will be ready to go. For sweeping, the operator can simply lower the main broom and all sweeping functions will be ready to go.
Use the Drive Pedal (MM) to control the speed of the machine. The speed of the machine will increase as the pedal is pushed closer to the floor. Do not press the Drive
Pedal (MM) until the Main Power Switch (CC) has been turned on.
SWEEPING
Follow the instructions in preparing the machine for use section of this manual.
1While seated on the machine, adjust the seat and steering wheel to a comfortable operating position using the adjustment controls (PP) and (LL).
2Release the Parking Brake (OO). To transport the machine to the work area, apply even pressure with your foot on the front of the Drive Pedal (MM) to go forward
or the rear of the pedal for reverse. Vary the pressure on the foot pedal to obtain the desired speed.
3Push the Lower Hopper Switch (Z) to make sure the hopper is seated properly.
4Move the Main Broom Lever (FF) to the SWEEP (middle notch) position to lower and enable the main broom. NOTE: The dump door opens automatically when
the main broom (FF) is lowered and closes when the broom is raised.
Use the FULL FLOAT (last notch forward) position only when sweeping extremely rough or uneven floors. Use at other times will only increase broom wear.
5When sweeping dry floors, push the Dust Control Switch (T) to turn ON the dust control system.
When sweeping floors with puddles, push the Dust Control Switch (T) to turn OFF the dust control system before the machine enters a puddle. Turn the dust control
system back ON when the machine is back on completely dry floor.
When sweeping wet floors, keep the Dust Control Switch (T) OFF at all times.
6Lower the Side Broom(s) (P) when sweeping along walls or curbs. Raise the Side Broom(s) (U) when sweeping in open areas. Push and hold the Side Broom
ON/DOWN Switch (P) to lower and start the side broom motor(s). NOTE: Hold the switch until the side broom(s) have lowered to the desired level. Side broom
sweeping pattern is adjusted by pushing switches (P & U) until the desired amount of down pressure is achieved. NOTE: If the side broom(s) were not raised
and turned OFF after last use, they will automatically lower and turn ON when the main broom is lowered and starts.
7Drive the machine straight forward at a quick walking speed. Drive the machine slower when sweeping large amounts of dust or debris or when safe operation dictates
slower speeds. Overlap passes 6 inches (15 cm).
8If dust comes out of the broom housing while sweeping, the Dust Control Filter (17) may be clogged. Push the Shaker Switch (S) to clean the dust control filter.
The dust control system (T) will automatically turn OFF while the shaker is running and turn ON after the shaker turns OFF (the shaker runs for 20 seconds).
9Check behind the machine occasionally to make sure that the machine is picking up debris. Dirt left behind in the path of the machine usually indicates that the machine
is moving too fast, the broom needs to be adjusted, or the hopper is full.
EMPTYING THE HOPPER
WARNING!
Make sure the Hopper Safety Support (HH) is in place whenever attempting to do any maintenance work under or near the raised
hopper. The Hopper Safety Support (HH) holds the hopper in the raised position to allow work to be performed under the hopper.
NEVER rely on the machine’s hydraulic components to safely support the hopper.
1Push the Shaker Switch (S) to remove excess dirt from the dust control filter. SERVICE NOTE:For best shaker performance always run the shaker with
the hopper
2Drive the machine close to a large trash receptacle and hold the Raise Hopper Switch (AA) until the hopper is all the way up. NOTE: The dump door automatically
closes when switch (AA) is pushed. You regain control of the dump door as soon as the hopper begins to raise so you can dump at any height if necessary.
3Move the machine forward until the hopper is over the receptacle, then press the Open Dump Door Switch (V) to open the dump door and empty the hopper.
4Check the back of the hopper and the front of the broom housing. Use a broom, if necessary, to remove litter from these areas. The back of the hopper must seal
tightly against the front of the broom housing for proper operation.
5Back the machine away from the receptacle until the hopper will clear it, and then lower the hopper (Z). NOTE: The dump door will automatically open when sweep
Follow the instructions in preparing the machine for use section of this manual.
1While seated on the machine, adjust the seat and steering wheel to a comfortable operating position using the adjustment controls (PP) and (LL).
2Release the Parking Brake (OO). To transport the machine to the work area, apply even pressure with your foot on the front of the Drive Pedal (MM) to go forward
or the rear of the pedal for reverse. Vary the pressure on the foot pedal to obtain the desired speed.
3Adjust the Solution Flow Control Lever (EE) to about 1/4 to 1/3 open position. The adjustment can be changed to allow variable solution flow for different types of
floors to be scrubbed. Example: A rough or absorbent floor surface, such as unfinished concrete will require more solution than a smooth finished floor.
5Press the Solution Switch (K) and hold for 5 seconds. This is done to pre-wet the floor. Note: This will help prevent scarring of the floor surface when starting to
scrub with dry brushes.
6Press the Scrub Pressure Decrease Switch (H) or the Scrub Pressure Increase Switch (I) to activate the scrub system. Note: refer to the “Operator’s Compartment
Descriptions” section for a more detailed explanation of these and other control panel functions.
7When the Scrub Pressure Decrease Switch (H) or the Scrub Pressure Increase Switch (I) are selected, the brushes and squeegee are automatically lowered to
the floor. The machine’s scrub brush rotation, solution system flow and vacuum starts when the Drive Pedal (MM) is activated. Note: When operating the machine
in reverse, only the brushes will rotate, the solution is automatically shut off to conserve the solution usage and the squeegee raises.
8Begin scrubbing by driving the machine forward in a straight line at a normal walking speed and overlap each path by 6 inches (15 cm). Adjust the machine speed
and solution flow according to the condition of the floor.
CAUTION!
To avoid damaging the floor, keep the machine moving while the brushes are turning.
9When scrubbing, check behind the machine occasionally to see that all of the waste water is being picked up. If there is water trailing the machine, you may be
dispensing too much solution, the recovery tank may be full, or the squeegee tool may require adjustment.
10 For extremely dirty floors, a one-pass scrubbing operation may not be satisfactory and a “double-scrub” operation may be required. This operation is the same as
a one-pass scrubbing except on the first pass the squeegee is in the up position (press the Vacuum Switch (N) to raise the squeegee). This allows the cleaning solution
to remain on the floor to work longer. The final pass is made over the same area, with the squeegee lowered to pick up the accumulated solution.
11 The recovery tank has an automatic vacuum shut-off to prevent solution from entering the vacuum system when the recovery tank is full. When the vacuum shut-
off is activated, the control system will shut down the vacuum system. The Recovery Tank FULL Indicator (M) will light. When the vacuum shut-off is activated,
the recovery tank must be emptied.
12 When the operator wants to stop scrubbing or the recovery tank is full, press the Scrub System OFF Switch (O) once. This will automatically stop the scrub brushes
and solution flow and the scrub deck will raise UP. NOTE: the vacuum/squeegee system will not be turned off when the switch is only pressed once. This is
to allow any remaining water to be picked up without turning the vacuum back on. Press the switch a second time and the squeegee will raise and the vacuum
will stop after a 10 second delay.
13 See the instructions below for emptying the recovery tank. Refill the solution tank and continue scrubbing.
EMPTYING THE RECOVERY TANK
1Drive the machine to a designated waste water “DISPOSAL SITE”.
2To empty, pull the Drain Hose (5) from its storage area, hold the end of the hose above the water level in the tank to avoid sudden, uncontrolled flow of waste water
and open the cap. NOTE: You can also pinch the flexible end of the hose to control waste water flow as shown below.
3Flush the tank and drain hose with clean water.
4Reclose the cap and return the hose to its storage area.
SERVICE NOTE: The recovery tank can be tipped out to the side for cleaning after emptying. Release the Latch (6) at the front of the tank and then pull out on the tank
with grip (26) until the tank reaches the end of its tether. Remove the recovery tank lid for easier cleaning. The recovery tank can also be removed for cleaning. You
will need to disconnect the wire harness and tether first and then use at least 2 people to lift off.
1Raise the squeegee, the scrub brushes, and the brooms.
2Shake the dust control filter and empty the hopper.
3Drain and flush the recovery tank.
4Tip the recovery tank out and check the squeegee hose elbow below the tank for debris. DO NOT run water down the recovery tank vacuum tubes, this may cause
damage to the vacuum motors.
5Remove and clean the squeegee tool.
6Remove and clean the scrub brushes. Rotate the scrub brushes.
7Wipe the machine with a damp cloth.
8Perform all required maintenance before storage.
9Move the machine to a clean, dry storage area.
10 Store the machine with the brooms, the squeegee and the scrub brushes in the UP position, and the tank covers open so that the tanks can air out.
REPORT ANY DEFECT OR MALFUNCTION NOTED DURING OPERATION TO AUTHORIZED SERVICE OR MAINTENANCE PERSONNEL.

Tighten the vent caps. If there is acid on the battery, wash the tops of the battery with a solution of baking soda and water (2 tablespoons
Since the Main Broom Motor always turns in the same direction, the bristles on the broom eventually become curved, reducing sweeping performance. Sweeping performance
can be improved by removing the broom and turning it around (end-for-end). This procedure, known as “rotating” the main broom, should be done once every 25 hours
of operation.
The main broom should be replaced when the bristles are worn to a length of 2-1/2 inches (6.35 cm). The main broom stop (GG) must be re-adjusted when the broom
is replaced. NOTE: Bristle length on a new broom is 3-1/4 inches (8.25cm).
NOTE: The machine should be stored with the Main Broom in the raised position.
WARNING!
Disconnect the battery (KK) before performing this operation.
To Rotate or Replace the Main Broom...
1Turn the Main Power Switch (CC) OFF.
2Put the Main Broom Raise / Lower (ON / OFF) Lever (FF) in the DOWN position.
3Open the Main Broom Right Access Door (29).
4See Figure 5. Remove the large T-Bolt (A) from the side of the broom idler arm. Pivot the idler arm assembly out of the main broom core.
5Pull the main broom out of the broom housing and remove any string or wire wrapped around it. Also inspect the skirts at the front, back and sides of the broom housing.
The skirts should be replaced or adjusted if they are torn or worn to a height of more than 1/4 inch (6.35 mm) off the ground.
6Turn the broom around (end-for-end) and slide it back into the broom housing. Make sure that the Lugs (B) on the broom drive hub (left side of machine) engage the
slots in the broom core.
7Swing the idler arm assembly back into the broom core and re-install the T-Bolt that holds the idler arm in place.
8Close and latch the Main Broom Right Access Door (29).
To Adjust the Main Broom Height...
1Drive the machine to an area with a level floor and set the parking brake (OO).
2Pull the Main Broom Raise / Lower (ON/OFF) Lever (FF) back and slide to the right and up to lower the main broom. Push lightly on the front of the Drive Pedal
(MM) to start the main broom rotating.
3Let the main broom run in place for 1 minute. This allows the broom to polish a “strip” on the floor. After 1 minute, raise the broom, release the parking brake and
move the machine so that the polished strip is visible.
4Inspect the polished strip on the floor. If the strip is less than 2 inches (5.08 cm) or more than 3 inches (7.62cm) wide, the broom needs to be adjusted.
5To adjust, loosen the Main Broom Adjust Knob (GG) and slide forward or backward to lower or raise the Main Broom. The farther the Knob (GG) travels up in the
slot, the
lower the Main Broom will be. Tighten Knob (GG) after adjustment is complete.
6Repeat steps 1-5 until the polished strip is 2-3 inches (5.08-7.62cm) wide.
The width of the polished strip should be the same at both ends of the broom. If the strip is tapered, move the machine to a different area and repeat steps 1-5. If
the polished strip is still tapered, contact your Nilfisk-Advance Dealer for service.
The side broom(s) move dirt and debris away from walls or curbs and into the path of the main broom. Adjust the side broom so that the bristles are contacting the floor
from the 10 O’clock (A) to the 3 O’clock (B) area shown in Figure 6 when the broom is down and running.
To adjust the Side Broom...
1The side broom(s) are adjusted simply by pressing and holding the Side Broom DOWN/ON Switch (P) or the Side Broom UP/OFF Switch (U) until the desired
amount of bristles are contacting the floor.
NOTE: The machine should be stored with the Side Broom(s) in the raised position. The Side Broom(s) should be replaced when the bristles are worn to a length of 3
inches (7.62 cm) or they become ineffective.
To replace the Side Broom...
1Raise the Side Broom(s).
2Reach under the Side Broom and remove the large Thumb-Nut holding the side broom on and remove the broom.
3Install the new broom by aligning the three alignment pins and pushing on. Re-install the Thumb-Nut and tighten.
After each use, clean the squeegee tool and check the blades for damage. If the squeegee leaves water in the middle of its path or at both ends of its path, it probably needs
to be adjusted. Reverse or replace the blades if they are cut, torn, wavy or worn.
To adjust the squeegee:
1Park the machine on a level floor, lower the squeegee and drive forward a short distance.
2See Figure 7. Loosen the two Squeegee Adjustment Lock Nuts (A).
3Turn the two Squeegee Adjustment Bolts (B) clockwise for forward tilt or counter-clockwise for backward tilt. Pull forward a short distance after each adjustment
to see if the squeegee blades touch the floor evenly across the entire width of the squeegee tool. Then re-tighten the two Nuts (A). NOTE: Hold Bolts (B) with wrench
while tightening Lock Nuts (A). If adjusting for more backwards tilt, tightening the Locknuts (A) after loosening the Adjustment Bolts (B) is what will actually tilt the
squeegee assembly.
To reverse or replace the rear squeegee blade:
1Unlatch the Rear Squeegee Blade Latch (C) and remove the (2) Wing Nuts (D).
2Remove both Rear Straps (E) and the Rear Squeegee Blade (F) from the machine.
3The squeegee blade has 4 working edges. Turn the blade so a clean, undamaged edge points toward the front of the machine. Replace the blade if all 4 edges are
nicked, torn or worn to a large radius.
4Install the blade, following the steps in reverse order and adjust the squeegee tilt.
To reverse or replace the front squeegee blade:
1Disconnect the Squeegee Hose from the squeegee tool.
2Loosen the (2) Squeegee Levers (G) and slide the squeegee assembly off of the squeegee mount.SERVICE NOTE: Depending on the position of the Squeegee Lever Handle (H), you may not be able to rotate the lever far enough to loosen or tighten depending on
which you are trying to do. In this case, simply lift UP on the Handle (H) and rotate the lever in the direction necessary to acquire adequate turning space and then
allow the lever to drop back DOWN into place on the hex. You can then either tighten or loosen as needed.
3Remove all of the Wing Nuts from the front squeegee blade strap.
4Remove the strap and blade from the squeegee assembly.
5The squeegee blade has 4 working edges. Turn the blade so a clean, undamaged edge points toward the front of the machine. Replace the blade if all 4 edges are
nicked, torn or worn to a large radius.
6Install the blade, following the steps in reverse order and adjust the squeegee tilt.
The hopper dust control filter must be cleaned regularly to maintain the efficiency of the vacuum system. Follow the recommended filter service intervals for the longest
filter life.
CAUTION!
Wear safety glasses when cleaning the filter.
Do not puncture the paper filter.
Clean the filter in a well-ventilated area.
To remove the hopper dust control filter...
1Lift the Hopper Cover (16) on top of the hopper. Make sure that the Hopper Cover Prop Rod (9) is in place.
2Inspect the top of the Hopper Dust Control Filter (17) for damage. A large amount of dust on top of the filter is usually caused by a hole in the filter or a damaged filter
gasket.
3Turn the two hold-downs to the side (one on each side at the front of the frame) to release the shaker frame, then swing the Dust Filter Shaker Assembly (18) up and
latch in place with the Shaker Assembly Latch (19).
4Lift the Hopper Dust Control Filter (17) out of the machine.
5Clean the filter using one of the methods below:
Method “A”
Vacuum loose dust from the filter. Then gently tap the filter against a flat surface (with the dirty side down) to remove loose dust and dirt. NOTE: Take care not
to damage the metal lip which extends past the gasket.
Method “B”
Vacuum loose dust from the filter. Then blow compressed air (maximum pressure 100 psi) into the clean side of the filter (in the opposite direction of the airflow).
Method “C”
Vacuum loose dust from the filter. Then soak the filter in warm water for 15 minutes, and then rinse it under a gentle stream of water (maximum pressure 40 psi).
Let the filter dry
6Follow the instructions in reverse order to install the filter. If the gasket on the filter is torn or missing, it must be replaced.
completely before putting it back into the machine.
HYDRAULIC OIL
Raise and prop (HH) the hopper. See Figure 8. The oil level should be approximately 1 inch (2.54cm) below the bottom of the Elbow (A) on the front of the reservoir
when the hopper is up (when the hopper is fully down the oil level should be up to the bottom of the elbow). If it is below this level, add 10W30 motor oil. Change the
oil if major contamination from a mechanical failure occurs. SERVICE NOTE: The Plug (B) on Elbow (A) on the side of the reservoir is for adding oil.
IMPORTANT!
This machine is equipped with an Indicator Light (F) which lights if the Hydraulic Oil Filter (C / Figure 8) requires changing. The
Hydraulic Filter (C / Figure 8) is found on the side of the Hydraulic Power Unit (27) as shown.
Change the gear lube in the drive wheel gear case after the first 350 hours of operation (break in period).
