OPERATING THE MACHINE MANUAL MODE
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.
1
Follow the instructions in "Starting the Machine" section and drive the machine to the work area to begin cleaning.
2
Press the One-Touch Scrub ON Switch (M) once for Regular Scrub. The brushes and squeegee are automatically lowered to the floor.
The scrub, solution, vacuum and detergent systems are all automatically enabled and will start when the Drive Pedal (3) is pressed. Any
individual system can be adjusted or turned OFF or ON by pressing its increase/decrease switches at any time during scrubbing.
Scrub Pressure: Scrub pressure can be adjusted by pressing the Scrub Pressure Increase Switch (A+) and Scrub Pressure Decrease
Switch (A) to change between (Regular, Heavy, Extreme). Observe the Scrub Pressure Indicators (A1).The scrub system can only be turned
OFF by pressing the One-Touch Scrub Switch (M).
Solution: The solution flow rate is increased or decreased independently of the scrub pressure by pressing the Solution Flow Increase
Switch (B+), and Solution Flow Decrease Switch (B) to change between (Low, Medium, High and Off). Observe the Solution Flow Indicators
(B1).
Vacuum: The vacuum is either ON (default) or OFF. Pressing the Vacuum Switch (F) will cycle between ON and OFF. While ON Vacuum
On Indicator (F1) will be lit.
NOTE: To pick up solution without scrubbing, press the Vacuum Switch (F) while in transport mode. This will cause the squeegee to
lower and the vac motor to turn ON.
Detergent: See "Detergent System Preparation and Use (EcoFlex)" for more detailed information regarding the adjustment and use of the
detergent system.
3
Begin scrubbing by driving the machine forward in a straight line at a normal walking speed and overlap each path by 2-3 inches (5 - 7.6 cm).
Adjust the machine speed and scrub parameters when necessary according to the condition of the floor.
4
Press the Burst of Power Switch (D) to temporarily (1 minute) increase detergent strength, scrub pressure and increase the solution flow rate
to the next available level. The Burst of Power Indicator (D1) will flash, after which all scrub parameters will return to their previous state.
5
When scrubbing, check behind the machine occasionally to see that all of the used solution is being picked up. If there is water trailing the
machine; you may be dispensing too much solution, the recovery tank may be full, there may be debris in the squeegee tool, squeegee
blades may be worn or the squeegee tool may require adjustment.
6
The recovery tank has a Tank Full Switch that causes ALL systems to turn 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: The Recovery Tank Full alert appears on the touchscreen when the switch is activated.
7
When the operator wants to stop scrubbing:
Press the One-Touch Scrub Switch (M) once. The scrub brushes and solution flow will stop and the scrub deck will raise. The squeegee
will raise up after a brief delay and the vacuum will stop after an additional 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.
8
Drive the machine to a designated waste water "DISPOSAL SITE" and empty the recovery tank. To empty, pull the Recovery Tank Drain Hose
(36) 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
flow of waste water). The drain hose can be squeezed to regulate the flow. Lift open the Recovery Tank Cover (29) to inspect and empty the
Debris Catch Tray (32) inside the recovery tank. Refill the solution tank and continue scrubbing.
NOTE: Make sure the Recovery Tank Cover (29) and the Recovery Tank Drain Hose (36) cap are properly seated or the machine will not pick-up
water correctly.
When the batteries require recharging the touchscreen will display a message stating low battery, the scrub brushes and solution flow will stop
and the scrub deck will raise up. The squeegee will raise up after a brief delay and the vacuum will stop after an additional delay. Transport the
machine to a service area and recharge the batteries according to the instructions in the Charging Gel/AGM (VRLA) Batteries section of this
manual.
