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) (Advenger models) or by loosening the mounting hardware (ST models).
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) (Advenger models)
or Battery Indicator (M) (ST models) 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) (Advenger models) or lowering the scrub deck using Scrub Deck Raise/Lower
Lever (14) (ST models).
5a Advenger models: 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
(AXP 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 (AXP 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.
5b ST models: Lower the scrub deck using the Scrub Deck Raise/Lower Lever (14), this will activate the solution and scrub systems. Lower the squeegee using the Squeegee
Raise/Lower Lever (22), this will activate the vacuum system. All systems will start when the Drive Pedal (3) is activated.
NOTE: There are two scrub pressure settings. Normal Pressure is achieved by lowering the scrub deck, the pressure on the brushes is caused by the weight of the deck.
Extreme Pressure is achieved by lowering the deck and then pressing down on the Lever (14) and moving it to the notch, this compresses a spring to create additional pressure
on the brushes.
NOTE: The solution fl ow rate can be changed by pressing the Solution Increase Switch (B) or Solution Decrease Switch (D).
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 Advenger models only: The machine defaults to the EverGreen cleaning mode (EverGreen Switch Indicator is lit GREEN) conserving solution and detergent. Press the
EverGreen Switch (J) to override the EverGreen cleaning mode and temporarily increase scrub pressure, solution fl ow and the detergent ratio. 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 ratio will increase to the pre-
programmed ratio. The pre-programmed ratio that is used during EverGreen override can be adjusted. With the detergent system OFF, 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 ratios (
1:256, 1:300, 1:400
). Once the desired ratio is displayed on the screen (F5), stop and it will lock in after 5 seconds.
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 for Advenger models or lift the Squeegee Raise/
Lower Lever (22) for ST models). 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.
10a Advenger models: 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.
10b ST models: 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.
11 When the operator wants to stop scrubbing or the recovery tank is full;
Advenger models: 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).
ST models: Use the Scrub Deck Raise/Lower Lever (14) to manually raise the scrub deck, this will stop the scrub motors and the solution fl ow. Use the Squeegee Raise/Lower
Lever (22) to manually raise the squeegee. The vacuum will stop after a brief delay (this is to allow any remaining water in the squeegee hose 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 (Advenger models) or the Battery Indicator (M) will fl ash red (ST models). Then the scrub brushes
and solution fl ow will stop and the scrub deck will raise up (Advenger models), manually raise the scrub deck on ST models. The squeegee will raise up after a brief delay and the
vacuum will stop after a brief delay (Advenger models), manually raise the squeegee on ST models. Transport the machine to a service area and recharge the batteries according to
the instructions in the Battery section of this manual.
