DETERGENT SYSTEM PREPARATION AND USE (ECOFLEX MODELS ONLY)
COMMON INSTRUCTIONS:
Pressing and releasing the Detergent Switch (F) 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 Àoor 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 (B) and the Detergent Switch (F) down for 2 seconds. NOTE: Once
activated the purge process takes 10 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 ¿lled with clean water
2 Turn the Key Switch (A) ON. Press and hold the Solution Switch (B) and the Detergent Switch (F) down for 2 seconds. NOTE: Once
activated the purge process takes 10 seconds. See illustration on next page for Detergent System indicators. Normally one purge cycle is
adequate to purge the system.
When the Detergent Cartridge is almost empty a Display Panel (D) indicator will come on. This “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 re¿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 Detergent Switch (F) and the EcoFlex Switch (G) down for 2 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 (F) for 2 seconds. The
detergent indicator will Àash 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 (D4), stop and it will lock in after 5 seconds.
CARTRIDGE SPECIFIC INSTRUCTIONS:
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 ¿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) as shown.

WET SCRUBBING
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.
1 Follow the instructions in the Preparing The Machine For Use section of this manual.
2 Turn the Master Key Switch (A) ON (I). This will display the control panel indicator lights, reference the Battery Indicator and Hour Meter on the Display (D or J).
3 To transport the machine to the work area, push the Drive Paddle (34) forward to go forward or pull the Drive Paddle (34) backward to move the machine in reverse. Vary the
pressure on the Drive Paddle (34) to obtain the desired speed.
NOTE: Speed Control Knob (35) is used to control the maximum speed in either forward or reverse.
4 Press and hold the Solution Switch (B) for 5 seconds to pre-wet the Àoor. NOTE: This must be done prior to pressing the Scrub ON Switch (I).
5 Press the Scrub ON Switch (I) once for Regular Scrub or twice for Heavy Scrub mode. Hold this switch for 5 seconds for Extreme Scrub mode. Both the solution system
and detergent system have 3 Àow rate presets that coincide with the 3 scrub modes (see Control Panel). NOTE: There is a solution Àow rate over ride function if you wish
to increase solution Àow without increasing scrub pressure. Hold the Solution Switch (B) for 3 seconds (solution indicator will start Àashing) and then let go. You then have 3
seconds to set a different Àow rate by simply pressing the Solution Switch (B) repeatedly until the Solution Flow Rate Indicator (D1) shows the rate you desire (Regular, Heavy or
Extreme / see Control Panel). Any subsequent scrub pressure adjustments will reset the solution Àow rate to default.
NOTE: The solution, vacuum and detergent (EcoFlex models) systems are automatically activated when the Scrub ON Switch (I) is pressed. No further action is required other
than lowering the squeegee (17). Any individual system can be turned OFF or back ON by simply pressing its switch at any time during scrubbing.
6 Lower the squeegee with the Squeegee Raise / Lower Lever (17).
7 When the Drive Paddle (34) is in the neutral position, the scrub, vacuum, solution and detergent (EcoFlex models) systems are activated but not running. Grip the Operator
Control Handle (2) and push the Drive Paddle (34) forward to start the scrub, vacuum, solution and detergent (EcoFlex models), and to move the machine forward. For best
results, move the machine at a slow walking speed. Press the Solution Switch (B) once to turn OFF while making sharp turns. Pull the Drive Paddle (34) backward to move the
machine in reverse. The brushes will run while moving the machine in reverse, but solution and chemical will not be dispensed.
CAUTION!
To avoid damaging the Àoor, keep the machine moving while the brushes are turning.
8 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.
9 EcoFlex models only: The machine defaults to the EcoFlex cleaning mode (EcoFlex Switch Indicator is lit GREEN) conserving solution and detergent. Press the EcoFlex
Switch (G) to override the EcoFlex cleaning mode and temporarily increase scrub pressure, solution Àow and the detergent ratio. This will cause the indicator to Àash green for
one minute, solution Àow 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 (F) for 2 seconds.
The detergent indicator will Àash 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 (D4), stop and it will lock in after 5 seconds.
NOTE: Pressing and holding the EcoFlex Switch (G) for 2 seconds disables the EcoFlex system. The only way to re-enable is to push the EcoFlex Switch (G) again. Cycling
the Key Switch (A) does not re-enable the system. The EcoFlex system will only function if the Scrub System (I) has been enabled.
10 For extremely dirty Àoors, 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 is in the up position. This allows the cleaning solution to remain on the Àoor to work longer. The ¿nal pass is made over the
same area, with the squeegee lowered to pick up the accumulated solution.
11 The recovery tank has an automatic shut-off switch that turns ALL systems 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: All other indicators vanish and a “Recovery Tank FULL” Indicator (D7) turns on in the Display Panel when the switch is activated on “EcoFlex” models. The Hour Meter
(J2) momentarily Àashes each letter of the word FULL over and over on “Standard” models.
12 When the operator wants to stop scrubbing or the recovery tank is full, press the Scrub OFF Switch (H) once. This will automatically stop the scrub brushes and solution Àow and
the scrub deck will raise UP. NOTE: The vacuum will stop after a 10 second delay. This is to allow any remaining water to be picked up without turning the vacuum back on.
13 Raise the squeegee and drive the machine to a designated wastewater “DISPOSAL SITE” and empty the recovery tank. To empty, pull the Recovery Tank Drain Hose (27) from
its hanger and open the cap (hold the end of the hose above the water level in the tank to avoid sudden, uncontrolled Àow of waste water). The Recovery Tank Drain Hose (27)
can be squeezed to regulate the Àow. Re¿ll the solution tank and continue scrubbing.
NOTE: Make sure the Recovery Tank Cover (5) and the Recovery Tank Drain Hose (27) cap is properly seated or the machine will not pick-up water correctly.
When the batteries require recharging the Battery LOW Indicator (D8) will come on (EcoFlex models) or the Battery Indicator (J1) will Àash red (Standard models)
and the vacuum motor will shut off after 30 seconds. Transport the machine to a service area and recharge the batteries according to the instructions in the Battery
section of this manual.
