PREPARE THE MACHINE FOR USE
LEAD-ACID BATTERIES
If your machine shipped with batteries installed do the following:
- Check that the batteries are connected to the machine.
- Turn ON the Power Switch (B) and check the Battery Indicator (C3). If the gauge is completely filled the batteries are ready for use. If the gauge is less than full the batteries should be charged before use. See the “Charging The Batteries” section.
If your machine shipped without batteries installed do the following:
- Consult your Authorized Advance dealer for recommended batteries.
- Install the batteries by following the instructions below.
LEAD-ACID BATTERY INSTALLATION
When Servicing Batteries...
- Remove all jewelry
- Do not smoke
- Wear safety glasses, rubber gloves and a rubber apron
- Work in a well-ventilated area
- Do not allow tools to touch more than one battery terminal at a time
- ALWAYS disconnect the negative (ground) cable first when replacing batteries to prevent sparks.
- ALWAYS connect the negative cable last when installing batteries.
LEAD-ACID BATTERIES - CONTINUED
- Remove the batteries from their shipping crate and carefully inspect them for cracks or other damage. If damage is evident, contact the carrier that delivered them or the battery manufacturer to file a damage claim.
- Turn the Power Switch (B) OFF and remove the magnetic SmartKey.
- Raise the steering column to the full upright position. Tip the seat forward and engage the Seat Prop Rod (9).
- Remove the crossbar and if installed also remove the overhead guard.
- Remove the recovery tank from the machine. NOTE: Disconnect the recovery switch wiring and the vacuum motor wiring then lift the tank straight up and off the machine.
- Your machine comes from the factory with enough battery cables to install six 6 volt batteries. Using at least (2) people and an appropriate lifting strap, carefully lift the batteries into the battery compartment and arrange them exactly as shown in FIGURE 1. Secure the batteries as close to the front and right side of the machine as possible. Use battery spacer to keep batteries from moving. If installing a mono-block battery use an overhead hoist (the seat support bracket will need to be temporarily removed to install a mono-block battery).
- Install the battery cables as shown. Position the cables so the battery caps can be easily removed for battery service.
- Carefully tighten the nut in each battery terminal until the terminal will not turn. Do not over-tighten the terminals, or they will be very difficult to remove for future service.
- Coat the terminals with spray-on battery terminal coating (available at most auto parts stores).
- Put one of the black rubber boots over each of the terminals and connect the Machine Battery Connector (10).
- Make sure the Fuse Holder Boot (14) is covering the fuse holder, the cable end of the Machine Battery Connector (10), and as much of the battery terminal as possible. Leave the protective caps supplied with the batteries in place or re-use to cover the terminal areas not protected by the terminal cover boots.
When changing batteries or the charger, please contact your local authorized service center for correct battery, charger and machine settings to prevent battery damage.
FIGURE 1

INSTALL THE BRUSHES (DISC SYSTEM)
- Make sure the Scrub Deck is in the RAISED position. Make sure the Power Switch (B) is off.
- Unlatch and swing open the Scrub Deck Side Doors (15).
- See Figure 2. Remove both Side Blade Assemblies (AA). NOTE: The blades are held in place by a large Knob (BB). Loosen these knobs and slide the Blade Assemblies (AA) forward slightly and then off of the Scrub Deck.
4a To manually install the brushes:
Lift the Brushes (DD) (or pad holders) and align the lugs on the brush with the holes on the mounting plate then turn to lock in place (turn the outside edge of brush towards the front of machine as shown by arrow (EE)).
4b To use the automatic Brush Install feature:
- Press the Guide Bar (CC) forward while sliding the brush under the deck and stop when the brush is contacting both legs of the guide bar. Repeat this step for the brush on the other side of the deck. NOTE: Do not push the first brush out of position with the second brush.
- Turn the machine ON at the Power Switch (B). (SCRUB SYSTEM MUST BE OFF and MACHINE IN NEUTRAL)
- Press the Brush Install Switch (O) the display will show Brush Install Indicator (C18) then wait for the brush install sequence to finish.
- Reinstall the side blade assemblies and close the deck side doors. NOTE: While scrubbing the brushes rotate as shown by arrow (FF).
FIGURE 2

INSTALL THE BRUSHES (CYLINDRICAL SYSTEM)
- Make sure the Scrub Deck is in the RAISED position. Make sure the Power Switch (B) is off.
- Unlatch and swing open the Scrub Deck Side Doors (15).
- See Figure 3. Unlatch and swing open both Side Blade Assemblies (AA).
- Unhook the Latch (AB) on top of the Idler Assemblies (AC) and remove.
- Slide the brush into the housing, lift slightly, push and turn until the tabs on the drive hub seat into the notches in the brush. NOTE: The idler is designed with a snug fit into the brush to reduce vibration. Re-install the Idler Assemblies (AC) make sure the tabs on the idler are inside of the weldment (as shown in Figure 3). Secure with Latch (AB). Close and latch both the Blade Assemblies (AA) and Scrub Deck Doors (15).
FIGURE 3

FILLING THE SOLUTION TANK
See Figure 4. Fill the solution tank with a maximum of 50 gallons (190 Liters) of cleaning solution. Do not fill the solution tank above 5 cm (2 inches) from the bottom of the Solution Fill (32). The solution should be a mixture of water and the proper cleaning chemical for the job. Always follow the dilution instructions on the chemical container label. NOTE: EcoFlex machines can either be used conventionally with detergent mixed in the tank or the detergent dispensing system can be used. When using the detergent dispensing do not mix detergent in the tank, plain water should be used.

SOLUTION TANK INDICATOR
See Figure 5-1. The solution tank has a level sensor with four measurement points. The Solution Level Indicator (C4) displays the level (1-4) of the solution in the tank. Once the tank is empty the Solution Empty Indicator (C26) will flash on the display.

SOLUTION SHUTOFF VALVE
See Figure 5-2. A bidirectional Shutoff Valve (30) permits the solution flow to be shutoff, directed toward the scrub deck, or directed toward the drain hose. The flow is off when the handle is perpendicular to the body. When the handle is turned completely in direction shown (arrow ‘A’), solution flow will be directed toward Solution Filter (29) & scrub deck.

SQUEEGEE INSTALLATION
- See Figure 6. Ensure the Squeegee Seal (AA) is free from debris and installed on the Squeegee Assembly (24). Lift the squeegee assembly by its Handles (AB) and slide it onto the Squeegee Mount (AC) and tighten the Squeegee Mount Thumb Nuts (21).

DETERGENT SYSTEM PREPARATION (ECOFLEX MODELS ONLY)
FILL THE DETERGENT CARTRIDGE
In the event of a detergent spill follow these four steps:
- Communicate the hazard. Immediately notify others working in the area and any supervisory personnel of the hazard, and if the situation warrants it, evacuate the area.
- Control the spill. Ensure the spill does not become any worse.
- Contain the hazard.
- Clean up the spill and any damage safely.
The Detergent Cartridge (8) is located beneath the seat. Fill the detergent cartridge with a maximum of 1 gallon (4 Liters) of detergent.
It is recommended that a separate cartridge be used for each detergent you plan to use. The detergent cartridges have a white decal on them so you can write the detergent name on each cartridge for clarification. When installing a new cartridge, remove the Factory Cap (AA) and place the cartridge in the machine. Install the Dry Break Cap (BB) and detergent hose as shown in Figure 7-1.
The system should be purged of previous detergent when switching to a different detergent (see “To Purge When Changing Detergent”).

To stop all machine functions immediately, press the Emergency Stop (U).- The display will show Emergency Stop Activated Indicator (C20).
- To reset the machine functions, rotate the emergency stop clockwise.

OPERATING THE MACHINE
While on ramps or inclines, avoid sudden stops when loaded. Avoid abrupt sharp turns. Use low speed down hills.
To Scrub...
Follow the instructions in “Starting the Machine” section and drive the machine to the starting point for cleaning.
- Press the Solution Switch (H) and hold for 5 seconds to pre-wet the floor. NOTE: This will help prevent scarring of the floor surface when starting to scrub with dry brushes. This must be done prior to pressing the One-Touch Scrub Switch (E).
- Press the One-Touch Scrub ON Switch (E) once for Regular Scrub. Press the Scrub Pressure Increase Switch (F) once for Heavy Scrub or twice for Extreme Scrub mode. The solution flow has settings that coincide with the scrub pressure, it will increase and decrease along with the scrub pressure.
NOTE: The solution flow rate can also be increased or decreased independently of the scrub pressure by pressing the Solution Flow Increase Switch (J) or Solution Flow Decrease Switch (K), observe the Solution Flow Rate Bar Graph (C10) (see Control Panel). Any subsequent scrub pressure adjustments will reset the solution flow rate to default. - When the One-Touch Scrub ON Switch (E) is selected, the brushes and squeegee are automatically lowered to the floor. The scrub, solution, vacuum and detergent (EcoFlex models) systems are all automatically enabled and will start when the Drive Pedal (3) is activated. Any individual system can be turned OFF or back ON by simply pressing its switch at any time during scrubbing.
NOTE: When operating the machine in reverse the squeegee automatically raises. - Begin scrubbing by driving the machine forward in a straight line at a normal walking speed and overlap each path by 2-3 inches (50-75 mm). Adjust the machine speed and solution flow when necessary according to the condition of the floor. Pull the Timed Solution Off Paddle (R) before entering a turn to temporarily turn off the solution flow. The Solution Flow Rate Bar Graph (C10) will be replaced by a 5 second countdown timer showing how long the solution flow will be off. Pull paddle again before timer runs out to cancel solution off.
NOTE: While scrubbing the maximum machine speed can be set by pressing the Speed Limiter Switch (N). Adjust the machine to the desired speed using the Drive Pedal (3) then press the Speed Limiter Switch (N). The operator can now press the pedal all the way forward without increasing the machine speed thereby reducing operator fatigue. The machine Speed (C5) is shown on the display.
- When 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.
- The machine defaults to the last cleaning mode used Minimum or Maximum Concentration Detergent (if detergent is installed and was activated). Pull the Burst of Power Paddle (S) to override the current cleaning mode and temporarily increase scrub pressure, solution flow and the detergent ratio (unless in Maximum Concentration). This will cause the Burst of Power Indicator (C15) to be displayed along with a countdown timer for one minute, solution flow rate will increase to the next level, scrub pressure will increase to the next level and the detergent ratio will be at the Maximum Concentration level (detergent system will be turned on at Minimum Concentration level if it was off).
NOTE: Repeatedly pressing and releasing the Detergent Switch (Q) will cycle between Minimum Concentration, Maximum Concentration and detergent off. The EcoFlex system will only function if the scrub system (E) has been enabled. - 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 and scrub deck blades are in the up position (press the Vacuum/Wand Switch (L) to raise the squeegee). Open both scrub deck Side Doors (15) and step down on the side blade Raise/Lower Lever (AA) to raise the side blades. 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 and side blades (step down on Lever (AA) again to lower) lowered to pick up the accumulated solution.
- The recovery tank has a Tank Full Switch (19) that causes ALL systems to turn OFF except the drive system when the recovery tank is full. When this switch is activated, the recovery tank must be emptied. The machine will not pick up water or scrub with the switch activated.
NOTE: Scrub, solution and detergent indicators vanish and the Recovery Tank Full Indicator (C13) appears on the Display Panel when the switch is activated. - When the operator wants to stop scrubbing or the recovery tank is full, press the One-Touch Scrub Switch (E) once. This will automatically stop the scrub brushes and solution flow and the scrub deck will raise up. The squeegee will raise up after a brief delay and the vacuum will stop after an additional delay (this is to allow any remaining water to be picked up without turning the vacuum back on).
- Drive the machine to a designated waste water “DISPOSAL SITE” and empty the recovery tank. To empty, pull the Drain Hose (20) from its rear storage area, then remove the plug (hold the end of the hose above the water level in the tank to avoid sudden, uncontrolled flow of waste water). Refill the solution tank and continue scrubbing.
When the batteries require recharging the Battery Low Voltage Indicator (C14) will come on, the scrub brushes and solution flow will stop and the scrub deck will raise up. The squeegee will raise up after a brief delay and the vacuum will stop after an additional delay. Transport the machine to a service area and recharge the batteries according to the instructions in the Battery section of this manual.
WET VACUUMING
Steps to follow in fitting the machine with optional attachments for wet vacuuming.
- Disconnect the recovery hose (33) from the squeegee mount. Connect the coupler and hose from the wand kit to the recovery hose.
- Attach suitable wet pick-up tools to the hose. (An optional Vac Wand Kit PN56116355 is available from Advance).
- Place the magnetic key onto the SmartKey Reader (A) and press the Power Switch (B). While standing alongside the machine (not on the seat) press the Vacuum/Wand Switch (L). The vacuum motor and the pump will run continuously until the switch is pressed again to turn it OFF. The Wand Indicator (C17) is displayed. NOTE: Pressing the Vacuum/Wand Switch (L) while seated on the machine will cause the squeegee to lower and the vacuum motor(s) to run while machine is moving forward. The Vacuum Indicator (C16) will be displayed.
SERVICE NOTE: Refer to the service manual for detailed functional descriptions of all controls and optional programmability.

- Tighten Tilt Stop Knob (AH) against the squeegee mount to lock adjustment.
SQUEEGEE MAINTENANCE - CONTINUED
FIGURE 13

SIDE BLADE MAINTENANCE
The side blade’s function is to channel the waste water to the squeegee, helping contain the water within the machines cleaning path. During normal use the blades will wear in time. The operator will notice a small amount of water leaking out underneath the side blades. A height adjustment can easily be made to lower the blades so that all the water can be picked-up by the squeegee.
To reverse or replace the scrub system side blades ...
- Unlatch and open the scrub deck side doors (15).
- See Figure 14-1. Unlatch the retaining strap (AA) and remove the strap and blade.
- The main side blade has 4 working edges as shown. Turn the blade so a clean, undamaged edge faces toward the center of the machine. Swap the right and left side blades to use the remaining two edges. Replace the blades as a set if all edges are nicked, torn or worn beyond their ability to be adjusted.
- Reinstall the blade onto the blade assembly and secure by latching the retainer strap (AA). Adjust the blade for proper contact to the floor when the brush deck is placed in the scrub position.
SIDE BLADE HEIGHT ADJUSTMENT
- The down stop can be adjusted on the side blades to compensate for blade wear.
- Make sure the machine is on a level surface.
- Lower the scrub deck by pressing the One-Touch Scrub Switch (E) and drive the machine forward a short distance to ensure the blades fold over.
- Open the scrub deck side doors (15) and observe blade fold over.
- To adjust, loosen the Side Blade Lock Knob (AB). Turn the Down Stop Knob (AC) (Up or Down) to where the blades just fold over enough when scrubbing that all the waste water is contained inside the deck. NOTE: Make small adjustments to obtain good blade wiping. Do not lower the blades too much to where they fold over excessively and cause unneeded blade wear.Tighten the Side Blade Lock Knob (AB) to lock the adjustment.
SIDE BLADE PRESSURE ADJUSTMENT
- The scrub deck side blades have two settings for down pressure.
- See Figure 14-2. Position 1 (AE) is normal wiping pressure, it is recommended to start at this setting. Position 2 (AF) is heavy wiping pressure, this setting can be used if wiping performance is not satisfactory. NOTE: Position 2 will cause faster blade wear.
- Pull Bracket (AG) to change between the two settings. Use the same setting on both sides of the scrub deck.
DOUBLE SCRUB POSITION
- See Figure 14-3. Step down on Blade Raise/Lower Lever (AH) to raise blade. NOTE: This position can also be used for installing/removing brushes.
- When finished double scrubbing with the machine, step down again on Lever (AH) or pull Release Bracket (AJ) to lower side blade back to its normal operating position.
