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 8. While seated on the machine, adjust the seat and steering wheel to a comfortable operating position using the adjustment controls (23) and (5).
2 Turn the Master Key Switch (A) ON (I). This will display the control panel indicator lights. Reference the Battery Condition Indicator (K5) and Hour Meter (K3) before proceeding.
3 Release the Parking Brake (6). To transport the machine to the work area, apply even pressure with your foot on the front of the Drive Pedal (8) 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 the Solution Switch (F) and hold for 5 seconds to pre-wet the fl oor. 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 (D).
5 Press the Scrub ON Switch (D) once for Regular Scrub, twice for Heavy Scrub or three times for Extreme Scrub mode. Both the solution fl ow and detergent (EcoFlex models)
fl ow have 3 presets that coincide with the 3 scrub modes (see Control Panel).
NOTE: There is a solution fl ow rate override function if you wish to increase solution fl ow without increasing scrub pressure. Hold the Solution Switch (F) for 3 seconds (solution
indicator will start fl ashing) and then let go. You then have 3 seconds to set a different fl ow rate by simply pressing the Solution Switch (F) repeatedly until the Solution Flow
Indicator (K1) shows the rate you desire (1-5 / see Control Panel). Any subsequent scrub pressure adjustments will reset the solution fl ow rate to default.
NOTE: The scrub, solution, vacuum, detergent (EcoFlex models) and side broom (cylindrical models) systems are automatically enabled when the Scrub ON Switch (D) is
pressed. Any individual system can be turned OFF or back ON by simply pressing its switch at any time during scrubbing.
6 When the Scrub ON Switch (D) is selected, the brushes, squeegee and side brooms (cylindrical models) are automatically lowered to the fl oor. The scrub, solution, vacuum,
detergent (EcoFlex models) and side broom (cylindrical models) systems all start when the Drive Pedal (8) is activated.
NOTE: When operating the machine in reverse the squeegee automatically raises.
7 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.
NOTE: The maximum scrub speed can be increased by pressing the Scrub Speed Switch (L). The normal max scrub speed is 80% of transport speed. Pressing this switch
increases it to 100% of transport speed.
If scrubbing on a smooth fl oor surface or double-scrubbing turning on the Traction Control™ button (B) regulates the drive wheel torque providing increased control and
enhanced traction on the fl oor.
The side broom height can be adjusted. See the “Side Broom Maintenance” section of this manual.
CAUTION!
To avoid damaging the fl oor, 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 The machine defaults to the EcoFlex cleaning mode (EcoFlex Switch Indicator is lit) conserving solution and detergent. Press the EcoFlex Switch (G) 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 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.
10 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 (I) 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.
11 The recovery tank has a shut-off fl oat (15) 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 (K7) appears on the Display Panel when the fl oat is activated. If the control repeatedly gives a full
indication when the tank is not full, the automatic shut-off feature can be disabled, have a qualifi ed service technician refer to the service manual to perform this function.
12 When the operator wants to stop scrubbing or the recovery tank is full, press the Scrub OFF Switch (E) 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).
13 Drive the machine to a designated waste water “DISPOSAL SITE” and empty the recovery tank. To empty, pull the Drain Hose (19) 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 fl ow of waste water). Refi ll the solution tank and continue scrubbing.
NOTE: Make sure the Recovery Tank Cover (1) and the Recovery Tank Drain Hose (19) cap are properly seated or the machine will not pick-up water correctly.
When the batteries require recharging the Battery LOW Indicator (K8) will come on, 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 from the squeegee (17). 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 PN56413687 is available from Nilfi sk).
3 Turn the Master Key Switch (A) ON and press the Vacuum/Wand Switch (I). The vacuum motor and the pump 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.
