OPERATING THE MACHINE

WARNING!

Be sure you understand the operator controls and their functions.

While on ramps or inclines, avoid sudden stops. Avoid abrupt sharp turns. Use low speed down ramps.

To Scrub...

Follow the instructions in "Preparing the Machine for Use" section of this manual.

See Figure 6. Step onto the Platform (20) compressing Operator's Presence Pedal (19). NOTE: Do not press the Go Pedal (18) until you are ready to move the

machine.

Turn the Key Switch (A) ON (I). Wait a few seconds for the start-up sequence to ﬁ nish. The graphic display (F) will show the information screen [2]. Reference the

Battery Charge Level Indicator (F8) before proceeding.

To transport the machine to the work area, ﬁ rst push the Forward Drive Switch (L) or Reverse Drive Switch (N) to select the direction of travel and then apply pressure

with your foot on the Go Pedal (18). Safety Feature: If you press and hold the Go Pedal (18) prior to pressing either Forward (L) or Reverse (N) an "error 03" (F6) will

appear on the screen preventing the machine from moving. If this occurs cycle the key switch OFF and ON in order to operate the machine.

An audible alert from the horn will sound in reverse. Adjust machine speed by rotating the Speed Adjustment Knob (K) clockwise to go faster or counterclockwise to go

slower.

Press and hold the Solution Switch (W) to pre-wet the ﬂ oor, solution will be dispensed at the HIGH rate while the switch is held. NOTE: This will help prevent scarring

of the ﬂ oor surface when starting to scrub with dry brushes. This can only be done prior to pressing the One-Touch Scrub Switch (I).

Press the One-Touch Scrub Switch (I). The graphic display (F) will change to the scrubbing screen [1]. The scrub deck and squeegee will be lowered to the ﬂ oor. The

scrub, vacuum, solution and detergent systems are enabled and will all start when the Go Pedal (18) is activated. The scrub parameters are saved after each use.

When the key is turned ON and the One-Touch scrub button is pressed the scrub parameters (vacuum power, solution ﬂ ow rate, scrub pressure setting and detergent

strength) will all be remembered from previous use.

Scrub: Each press of the Brush Pressure Switch (T) will change between STANDARD pressure ((F3) bottom box ﬁ lled top box empty) and EXTRA pressure ((F3)

both bottom and top boxes ﬁ lled). The scrub system can only be turned OFF by pressing the One-Touch Scrub Switch (I).

Solution: The solution ﬂ ow rate can be changed independently of the scrub pressure by pressing the Solution Switch (W). Each press of the switch will cycle

between LOW, MEDIUM, HIGH, OFF and back to LOW. LOW is indicated when (F2) displays bottom box ﬁ lled, MEDIUM is indicated when (F2) displays bottom and

middle boxes ﬁ lled, HIGH is indicated when (F2) displays all three boxes ﬁ lled, and OFF is indicated when (F2) displays all three boxes empty.

Vacuum: The vacuum level can be changed independently. Each press of the Vacuum Switch (Y) will cycle between LOW, HIGH, OFF and back to LOW. LOW is

indicated when Vacuum Level Bar Graph (F1) displays bottom box ﬁ lled, HIGH is indicated when (F1) displays both bottom and top boxes ﬁ lled. OFF is indicated

when (F1) displays both bottom and top boxes empty. NOTE: To pick up solution without scrubbing, press the Vacuum Switch (Y) while in transport mode. This will

cause the squeegee to lower and the vac motor to turn ON at the LOW level.

Detergent: See "Detergent System Preparation and Use (EcoFlex)" for more detailed information regarding the adjustment and use of the detergent system.

Daily Scrub: Begin scrubbing by driving the machine forward in a straight line at a safe speed and overlap each path by 2-3 inches (50-75 mm). Adjust the machine

speed, scrub pressure, solution ﬂ ow and detergent level when necessary according to the condition of the ﬂ oor. NOTE: The machine speed can be adjusted by

rotating the Speed Adjustment Knob (K) clockwise to go faster or counterclockwise to go slower.

Floor Finish Removal (REV model only): Ensure there is a red pad attached directly to the ﬁ xed pad driver and that the maroon SPP pad is not attached to the ﬁ xed

pad driver. Adjust the scrub parameters as follows: Adjust the machine speed potentiometer to a slow scrub speed approximated by that shown in Figure 6 (K). Adjust

the solution ﬂ ow rate to low, the scrub pressure to high and turn detergent off. The vacuum power setting can be set to either low or high.

Press the Burst of Power Switch (P) to temporarily (1 minute) engage the strong detergent strength, extra scrub pressure, full vacuum power and increase the solution

ﬂ ow rate to the next available level. The Burst of Power Indicator (Q) will blink during this 1 minute interval, after which all scrub parameters will return to their previous

state.

CAUTION!

To avoid damaging the ﬂ oor, only start and stop the scrubbing function while the machine is in motion.

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.

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. Lift up the squeegee assembly and rotate the double scrub bracket (AA) down, to

hold the squeegee off the ﬂ oor. 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.

The recovery tank has a shut-off ﬂ oat (14) that causes a change in pitch in the vac motor. When this ﬂ oat is activated, the recovery tank must be emptied. The machine

will not pick up water with the ﬂ oat activated.

When the operator wants to stop scrubbing:

Press the One-Touch Scrub Switch (I) 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 with the scrub deck and the vacuum will stop after a brief time delay (this is to allow any remaining water to be picked up without turning the

vacuum back on) if the vacuum switch is pressed during this time delay the vacuum will turn off.

Drive the machine to a designated waste water "DISPOSAL SITE" and empty the recovery tank. To empty, pull the Recovery Tank Drain Hose (30) 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). The drain hose can

be squeezed to regulate the ﬂ ow. Unlatch (29) and lift open the Recovery Tank Cover (13) to inspect and empty the Debris Catch Tray (16) in the recovery tank. Reﬁ ll

the solution tank and continue scrubbing.

NOTE: Make sure the Recovery Tank Cover (13) and the Recovery Tank Drain Hose (30) cap are properly seated or the machine will not pick-up water correctly.

When the batteries require recharging the Battery Low Voltage Screen [3] will come on. Then the scrub brushes and solution ﬂ ow will stop and the scrub deck will raise up.

Once the battery voltage drops below a second cutoff level the squeegee will raise up 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.
