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 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.

When the Detergent Cartridge 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 Percentage:

1 The detergent percentage default is 0.25%. To change the percentage, the detergent system must be OFF, then 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 percentages (3%, 2%, 1.5%, 1%,

0.8%, 0.66%, 0.5%, 0.4%, 0.3%., 0.25%). Once the desired percentage 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). 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) 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). 5 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. 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 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 percentage. 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 percentage will increase to the next larger percentage. NOTE: For

machines that do not have detergent installed, pressing the EcoFlex switch will temporarily increase scrub pressure and solution ﬂ ow. NOTE: Pressing and holding the EcoFlex Switch (J) for 2 seconds disables the EcoFlex system. The only way to re-enable is to push the EcoFlex Switch (J) again. Cycling the

Key Switch (A) does not re-enable the system. The EcoFlex system will only function if the Scrub System (H) has been enabled. 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). 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. 10 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. 11 When the operator wants to stop scrubbing or the recovery tank is full, 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). 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. Then the scrub brushes and solution ﬂ 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 a brief 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 ﬁ tting the machine with optional attachments for wet vacuuming.

1 Disconnect the Recovery Hose (37) from the Squeegee (11). Connect the coupler and hose from the wand kit to the recovery hose. 2 Attach suitable wet pick-up tools to the hose. (An optional Wand Kit PN56601087 is available from Nilﬁ sk). 3 Turn the Master Key Switch (A) ON and press the Wand Switch (L). NOTE: The operator cannot be in the seat for the vacuum motor to run. The vacuum motor will run

continuously until the switch is pressed again to turn it OFF. NOTE: The “Recovery Tank FULL” indicator is disabled when the wand mode is activated. The ﬂ oat will stop the

ﬂ ow into the recovery tank.

SERVICE NOTE: Refer to the service manual for detailed functional descriptions of all controls and optional programmability.
