DETERGENT SYSTEM PREPARATION AND USE (ECOFLEX MODELS ONLY)

COMMON INSTRUCTIONS:

Pressing and releasing the Detergent Switch (E) while the solution system is active will cause the detergent system to alternately turn on and off. The system should be purged of previous detergent when switching to a different detergent. SERVICE NOTE: Move machine over ﬂ oor drain before purging because a small amount of detergent will be dispensed in the process.

To Purge When Changing Chemicals:

1 Disconnect and remove the detergent cartridge. 2 Turn the Key Switch (A) ON. Press and hold the Solution Switch (C) and the Detergent Switch (E) down for 3 seconds. NOTE: Once activated the purge

process takes 20 seconds. See illustration on next page for Detergent System indicators. Normally one purge cycle is adequate to purge the system.

To Purge Weekly:

1 Disconnect and remove the detergent cartridge. Install and connect a Cartridge ﬁ lled with clean water. 2 Turn the Key Switch (A) ON. Press and hold Solution Switch (C) and the Detergent Switch (E) down for 3 seconds. NOTE: Once activated the purge

process takes 20 seconds. See illustration on next page for Detergent System indicators. Normally one purge cycle is adequate to purge the system.

When the Detergent Cartridge (13) is almost empty a Display Panel (F4) indicator will come on. The “Low Detergent” indicator will remain on until you reset the system. Once this indicator comes on you should be able to simply pour an entire gallon bottle of detergent into the Cartridge to reﬁ ll without worrying about measuring. NOTE: Only reset the system when the cartridge is full. When switching cartridges, the “Low Detergent” indicator is only accurate if the replacement cartridge is at the same level as the cartridge being replaced.

To Reset:

1 Turn the Key Switch (A) ON. Press and hold the Solution Increase Switch (B) and the Solution Decrease Switch (D) down for 3 seconds. See illustration on

next page for Detergent System indicators.

Detergent Ratio:

1 The detergent ratio is locked at 1:400, except while overriding the EcoFlex cleaning mode. The pre-programmed ratio that is used during EcoFlex override

can be adjusted. With the detergent system OFF, press and hold the Detergent ON/OFF Switch (E) for 2 seconds. The detergent indicator will ﬂ ash and each press of the switch will cycle through the available ratios (1:32, 1:50, 1:64, 1:100, 1:128, 1:150, 1:200, 1:256, 1:300, 1:400). Once the desired ratio is displayed on the screen (F5), stop and it will lock in after 5 seconds.

CARTRIDGE INSTRUCTIONS:

The Detergent Cartridge (13) is located behind the Detergent Cartridge Access Door (12) in the operator’s compartment. Fill the detergent cartridge with a maximum of 1.25 gallons (4.73 Liters) of detergent. SERVICE NOTE: Remove the detergent cartridge from the detergent box prior to ﬁ lling to avoid spilling detergent on the machine. 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 to avoid mixing them up. When installing a new cartridge, remove the Cap (AA) and place the cartridge in the detergent box. Install the Dry Break Cap (BB) and detergent hose as shown.

OPERATING THE MACHINE

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. Clean only while ascending (driving up) the ramp.

To Scrub...

Follow the instructions in “preparing the machine for use” section of this manual.

1 See Figure 6. While seated on the machine, adjust the steering wheel to a comfortable position using the Steering Wheel Tilt Adjust Knob (23). The seat can be adjusted if

necessary by tipping up the seat and using the adjustment knob (18) (Advenger models) or by loosening the mounting hardware (ST models).

2 Turn the Master Key Switch (A) ON (I). This will display the control panel indicator lights. Reference the Battery Condition Indicator (F6) and Hour Meter (F1) (Advenger models)

or Battery Indicator (M) (ST models) before proceeding.

3 To transport the machine to the work area, apply even pressure with your foot on the front of the Drive Pedal (3) to go forward or the rear of the pedal for reverse. Vary the

pressure on the foot pedal to obtain the desired speed.

4 Press and hold the Solution Switch (C) to pre-wet the ﬂ oor, solution will be dispensed while the switch is held. NOTE: This will help prevent scarring of the ﬂ oor surface when

starting to scrub with dry brushes. This must be done prior to pressing the Scrub ON Switch (H) (Advenger models) or lowering the scrub deck using Scrub Deck Raise/Lower Lever (14) (ST models).

5a Advenger models: Press the Scrub ON/OFF Switch (H), the scrub deck and squeegee will automatically be lowered to the ﬂ oor. The scrub, vacuum, solution and detergent

(EcoFlex models) systems all start when the Drive Pedal (3) is activated.

The scrub pressure will default to Normal (one scrub pressure indicator lit). Use the Scrub Pressure Increase Switch (G) and Scrub Pressure Decrease Switch (I) to change

between Normal, Heavy and Extreme Scrub modes. The solution ﬂ ow rate will automatically adjust to coincide with the scrub pressure. NOTE: The solution ﬂ ow rate can be changed independently of the scrub pressure by pressing the Solution Increase Switch (B) or Solution Decrease Switch (D). Any subsequent scrub pressure adjustments will reset the solution ﬂ ow rate to correspond with the scrub pressure. NOTE: The scrub, solution, vacuum and detergent (EcoFlex models) systems are automatically enabled when the Scrub ON/OFF Switch (H) is pressed. 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.

5b ST models: Lower the scrub deck using the Scrub Deck Raise/Lower Lever (14), this will activate the solution and scrub systems. Lower the squeegee using the Squeegee

Raise/Lower Lever (22), this will activate the vacuum system. All systems will start when the Drive Pedal (3) is activated.

NOTE: There are two scrub pressure settings. Normal Pressure is achieved by lowering the scrub deck, the pressure on the brushes is caused by the weight of the deck.

Extreme Pressure is achieved by lowering the deck and then pressing down on the Lever (14) and moving it to the notch, this compresses a spring to create additional pressure on the brushes. NOTE: The solution ﬂ ow rate can be changed by pressing the Solution Increase Switch (B) or Solution Decrease Switch (D).

6 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 ﬂ ow when necessary according to the condition of the ﬂ oor.

CAUTION!

To avoid damaging the ﬂ oor, keep the machine moving while the brushes are turning.

7 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.

8 Advenger models only: The machine defaults to the EcoFlex cleaning mode (EcoFlex Switch Indicator is lit GREEN) conserving solution and detergent. Press the EcoFlex

Switch (J) to override the EcoFlex cleaning mode and temporarily increase scrub pressure, solution ﬂ ow and the detergent ratio. This will cause the indicator to ﬂ ash yellow for one minute, solution ﬂ ow rate will increase to the next level, scrub pressure will increase to the next level and the detergent ratio will increase to the pre-programmed ratio. The pre-programmed ratio that is used during EcoFlex override can be adjusted. With the detergent system OFF, press and hold the Detergent ON/OFF Switch (E) for 2 seconds.

The detergent indicator will ﬂ ash and each press of the switch will cycle through the available ratios ( Once the desired ratio is displayed on the screen (F5), stop and it will lock in after 5 seconds.

9 For extremely dirty ﬂ 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 ﬁ rst pass the squeegee is in the up position (press the Vacuum/Wand Switch (L) to raise the squeegee for Advenger models or lift the Squeegee Raise/ Lower Lever (22) for ST models). This allows the cleaning solution to remain on the ﬂ oor to work longer. The ﬁ nal pass is made over the same area, with the squeegee lowered to pick up the accumulated solution.

10a Advenger models: The recovery tank has a shut-off ﬂ oat (29) that causes ALL systems to turn OFF except the drive system when the recovery tank is full. When this ﬂ oat is

activated, the recovery tank must be emptied. The machine will not pick up water or scrub with the ﬂ oat activated.

NOTE: All other indicators vanish and a “Recovery Tank FULL” Indicator (F7) appears on the Display Panel when the ﬂ oat is activated. 10b ST models: The recovery tank has a shut-off ﬂ oat (29) that causes ALL systems to turn OFF except the drive system when the recovery tank is full. When this ﬂ oat is activated,

the recovery tank must be emptied. The machine will not pick up water or scrub with the ﬂ oat activated.

11 When the operator wants to stop scrubbing or the recovery tank is full; Advenger models: Press the Scrub ON/OFF Switch (H) once. This will automatically stop the scrub brushes and solution ﬂ ow and the scrub deck will raise up. The squeegee

will raise up after a brief delay and the vacuum will stop after a brief delay (this is to allow any remaining water to be picked up without turning the vacuum back on).

ST models: Use the Scrub Deck Raise/Lower Lever (14) to manually raise the scrub deck, this will stop the scrub motors and the solution ﬂ ow. Use the Squeegee Raise/Lower

Lever (22) to manually raise the squeegee. The vacuum will stop after a brief delay (this is to allow any remaining water in the squeegee hose to be picked up without turning the vacuum back on).

12 Drive the machine to a designated waste water “DISPOSAL SITE” and empty the recovery tank. To empty, pull the Drain Hose (31) from its rear storage area, then unscrew the

cap (hold the end of the hose above the water level in the tank to avoid sudden, uncontrolled ﬂ ow of waste water). Reﬁ ll the solution tank and continue scrubbing.

NOTE: Make sure the Recovery Tank Cover (26) and the Recovery Tank Drain Hose (31) cap are properly seated or the machine will not pick-up water correctly. When the batteries require recharging the Battery LOW Indicator (F8) will come on (Advenger models) or the Battery Indicator (M) will ﬂ ash red (ST models). Then the scrub brushes

and solution ﬂ ow will stop and the scrub deck will raise up (Advenger models), manually raise the scrub deck on ST models. The squeegee will raise up after a brief delay and the vacuum will stop after a brief delay (Advenger models), manually raise the squeegee on ST models. Transport the machine to a service area and recharge the batteries according to the instructions in the Battery section of this manual.

1:32, 1:50, 1:64, 1:100, 1:128, 1:150, 1:200, 1:256, 1:300, 1:400).
