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 Panel (D).

3 To transport the machine to the work area, push the Drive Paddle (30) forward to go forward or pull the Drive Paddle (30) backward to move the

machine in reverse. Vary the pressure on the Drive Paddle (30) to obtain the desired speed.

NOTE: Speed Control Knob (13) 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 ﬂ oor. 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 ﬂ ow rate presets that coincide with the 3 scrub modes (see Control Panel). NOTE:

There is a solution ﬂ ow rate over ride function if you wish to increase solution ﬂ ow without increasing scrub pressure. Hold the Solution Switch

(B) 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 (B) repeatedly until the Solution Flow Rate Indicator shows the rate you desire (Regular, Heavy or Extreme / see Control

Panel). Any subsequent scrub pressure adjustments will reset the solution ﬂ ow rate to default.

NOTE: The solution, vacuum and detergent (EDS only) systems are automatically activated when the Scrub ON Switch (I) is pressed. No

further action is required other than lowering the squeegee (15). Any individual system can be turned OFF or back ON by simply pressing its

switch at any time during scrubbing. If you have installed the Extended Scrub Kit, it will not be automatically activated. You must press the

Recycle Switch (G) to activate this system. The recycle system will not turn ON until the water level in the recovery tank reaches a certain level.

6 Lower the squeegee with the Squeegee Raise / Lower Lever (15).

7 When the Drive Paddle (30) is in the neutral position, the scrub, vacuum, solution and detergent (EDS only) systems are activated but not

running. Grip the Operator Control Handle (2) and push the Drive Paddle (30) forward to start the scrub, vacuum, solution and detergent (EDS

only), 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 (30) 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 ﬂ oor, keep the machine moving while the brushes are turning.

8 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. 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.

9 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 (FF) turns on in the Display Panel when the switch is activated.

10 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 ﬂ ow 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.

11 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 (22) from its hanger, then open the cap (hold the end of the hose above the water level in the tank to avoid sudden,

uncontrolled ﬂ ow of waste water). The Recovery Tank Drain Hose (22) can be squeezed to regulate the ﬂ ow. Reﬁ ll the solution tank and

continue scrubbing.

NOTE: Make sure the Recovery Tank Cover (5) and the Recovery Tank Drain Hose (22) 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 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.

WET VACUUMING

Fit the machine with optional attachments for wet vacuuming.

1 Disconnect the Recovery Hose (28) from the Squeegee (12).

2 Attach suitable wet pick-up tools to the hose (Available from Nilﬁ sk).

3 Turn the Master Key Switch (A) ON.

4 Press the Wand Switch (E) once to turn ON the vacuum motor.

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