OPERATING THE MACHINE (DISC & CYLINDRICAL) WARNING! Be sure you understand the operator controls and their functions. 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 start point for cleaning. 1 See Figure 3-1. Press the One-Touch Scrub ON Switch (M) once for Regular Scrub. Press the Scrub Pressure Increase Switch (M+) once for Heavy Scrub or twice for Extreme Scrub mode. The solution ow has settings that coincide with the scrub pressure, it will increase and decrease along with the scrub pressure. NOTE: The solution ow rate can also be increased or decreased independently of the scrub pressure by pressing the Solution Flow Increase Switch (F+) or Solution Flow Decrease Switch (F-), observe the Solution Flow Rate Bar Graph (C10). Any subsequent scrub pressure adjustments will reset the solution ow rate to default. 2 When the One-Touch Scrub ON Switch (M) is selected, the brushes and squeegee are automatically lowered to the oor. 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. Detergent: See “Detergent System Preparation and Use (EcoFlex) for detailed information regarding adjustment and use. 3 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 ow when necessary according to the condition of the oor. Push the Timed Solution Off Paddle (O) before entering a turn to temporarily turn off the solution ow. The Solution Flow Rate Bar Graph (C10) will be replaced by a 5 second countdown timer showing how long the solution ow will be off. Push 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 (L). 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. The speed limit will be in effect every time you scrub until the speed limiter switch is pressed again (while scrubbing) to disable the speed limit. CAUTION! To avoid damaging the oor, keep the machine moving while the brushes are turning. 4 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. 5 For extremely dirty oors, 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 rst pass the squeegee (33) and scrub deck blades (AA) are in the up position see Side Blade - Double Scrub Position. Press the Vacuum Switch (G) to raise the squeegee. This allows the cleaning solution to remain on the oor to work longer. The nal pass is made over the same area, with the squeegee and side blades lowered to pick up the accumulated solution 6 The recovery tank has a Shutoff Float (25). When the tank is full the oat is activated and closes the inlet so no more water can enter the recovery tank. When the oat is activated the operator may notice a change in the sound of the vacuum motor or will notice machine is no longer picking up water. When the shutoff oat is activated, the recovery tank must be emptied. The machine will not pick up water with the oat activated but no machine functions will turn off. 7 When the operator wants to stop scrubbing or the recovery tank is full, press the One-Touch Scrub Switch (M) once. This will automatically stop the scrub brushes and solution ow 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). When scrub is turned off the speed limit is also turned off and machine speed will go back to normal operation. 8 Drive the machine to a designated waste water “DISPOSAL SITE” and empty the recovery tank. To empty, pull the Recovery Tank Drain Hose (28) from its storage area. Hold the end of the hose above the water level in the tank then unscrew the cap. Squeeze the hose as shown until the hose is near the drain to avoid sudden uncontrolled ow of waste water. Screw on the cap and push the recovery tank drain hose back into its storage area. Rell the solution tank and continue scrubbing. NOTE: Make sure the Recovery Tank Cover (24) and the cap on the Recovery Tank Drain Hose (28) are properly seated or the machine will not pick-up water correctly. If the batteries become discharged to the low voltage cutout threshold the Battery Low Voltage Indicator (C14) will come on, the scrub brushes and solution ow 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.

The side blades’ 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. DISC - To reverse or replace the scrub system side blades ... 1 See Figure 4-6. Loosen the two Side Blade Assembly Removal Knobs (16) (2 per side) and pull the Side Blade Assembly (AA) slightly forward and then off the scrub deck. 2 Loosen the two Thumb Nuts (AL) then rotate the two Retainers (AB) to be horizontal and separate the blade from the retainer strap. 3 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. Replace the blades as a set if all edges are nicked, torn or worn beyond their ability to be adjusted. 4 Reinstall the blade onto the blade assembly and secure with Retainers (AB) by rotating back to the vertical position and tighten Thumb Nuts (AL). Adjust the blade height for proper contact to the oor when the brush deck is placed in the scrub position. See “Side Blade Height Adjustment” section. CYLINDRICAL - To reverse or replace the scrub system side blades ... 1 See Figure 4-7. Unlatch the retaining strap (AD) and remove the strap and blade. 2 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. 3 Reinstall the blade onto the blade assembly and secure by latching the retainer strap (AD). Adjust the blade for proper contact to the oor when the brush deck is placed in the scrub position. See “Side Blade Height Adjustment” section.

SIDE BLADE HEIGHT ADJUSTMENT

DISC - 1 See Figure 4-6. The side blade assembly knob removal screw studs have leveling Adjuster Collars (AC), that are to be raised or lowered to compensate for blade wear. 2 Make sure the machine is on a level surface. 3 Lower the scrub deck by pressing the One-Touch Scrub Switch (M) and drive the machine forward a short distance to ensure the blades fold over. 4 Observe blade fold over. 5 The side blade Removal Knobs (16) can be loosened with assembly left on and the Adjuster Collars (AC) rotated by reaching under the blade assembly. 6 Turn the Adjuster Collars (AC) (Up or Down) to where the blades just fold over enough when scrubbing that all the waste water is contained inside the scrub 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. CYLINDRICAL - 1 Make sure the machine is on a level surface. 2 Lower the scrub deck by pressing the One-Touch Scrub Switch (M) and drive the machine forward a short distance to ensure the blades fold over. 3 Observe blade fold over. 4a Fixed Side Blades: See Figure 4-7a. The side blade assembly knob removal screw studs have leveling Adjuster Collars (AC), that are to be raised or lowered to compensate for blade wear. Turn the Adjuster Collars (AC) (Up or Down) to where the blades just fold over enough when scrubbing that all the waste water is contained inside the scrub deck. 4b Adjustable Side Blades: See Figure 4-7b. Each side blade assembly has a Down Stop (AE), that can be raised or lowered to compensate for blade wear. Loosen the Down Stop (AE) and adjust (Up or Down) to where the blades just fold over enough when scrubbing that all waste is contained inside the scrub 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.9/2022 A - 41 56091272 - Advance SC4000

POSITION DISC - 1 See Figure 4-9. Loosen Side Blade Assembly Removal Knobs (16) and remove the Side Blade Assemblies (AA). 2 Place the Blade Assemblies (AA) onto the Blade Assembly Holders (AC) at the round holes in the blade assemblies. Repeat for blade assembly on the other side of the scrub deck.3 When nished double scrubbing with the machine, reinstall Side Blade Assemblies into their normal operating position and tighten Removal Knobs (16). FIGURE 4-8 1 The cylindrical scrub deck side blades have two settings for down pressure. See Figure 4-8. 2 Position 1 (AF) is normal wiping pressure, it is recommended to start at this setting. Position 2 (AG) is heavy wiping pressure, this setting can be used if wiping performance is not satisfactory. NOTE: Position 2 will cause faster blade wear.3 Pull the end of Spring (AH) and move between the two settings. Use the same setting on both sides of the scrub deck.CYLINDRICAL - Adjustable only1 See Figure 4-10. Lift up on Blade Raise/Lower Lever (AJ) to raise blade. While holding the lever in the raised position, rotate and engage the Latch (AK).2 When nished double scrubbing with the machine, lift up on Raise/Lower Lever (AJ) again and disengage the Latch (AK) and lower side blade back to its normal operating position.
