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 (D or J).
3
To transport the machine to the work area, push either of the Palm Buttons (29) to go forward or press either Palm Button (29) and the Reverse Button (28) to move the machine
in reverse.
NOTE: Speed Control Knob (30) 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 Pressure or twice for Heavy Scrub Pressure mode. Hold this switch for 5 seconds for Extreme Scrub Pressure mode.
Once the scrub system is activated, pressing the Solution Switch (B) will toggle between solution off, low, medium and high solution fl ow rates.
NOTE: The solution, vacuum and detergent (EcoFlex models) systems are automatically activated when the Scrub ON Switch (I) is pressed. No further action is required other
than lowering the squeegee (17). Any individual system can be turned OFF or back ON by simply pressing its switch at any time during scrubbing.
6
Lower the squeegee with the Squeegee Raise / Lower Lever (17).
7
When the Palm Buttons (29) are not being pressed (machine stationary), the scrub, vacuum, solution and detergent (EcoFlex models) systems are activated but not running.
Grip the Operator Control Handle (2) and press either of the Palm Buttons (29) to start the scrub, vacuum, solution and detergent (EcoFlex models), and to move the machine
forward. For best results, move the machine at a slow walking speed. Press either palm button and the reverse button to move the machine in reverse. The brushes will run
while moving the machine in reverse, but solution and dteregent will not be dispensed.
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
EcoFlex models only: The machine defaults to the EcoFlex cleaning mode (EcoFlex Switch Indicator is lit GREEN) 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 ratio. This will cause the indicator to fl ash green 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 EcoFlex override can be adjusted. With the detergent system OFF, press and hold the Detergent ON/OFF Switch (F) for 2 seconds.
The detergent indicator will fl ash and each press of the switch will cycle through the available ratios (1:32, 1:50, 1:64, 1:100, 1:128, 1:150, 1:200, 1:256, 1:300, 1:400). Once the
desired ratio is displayed on the screen (D4), stop and it will lock in after 5 seconds.
NOTE: Pressing and holding the EcoFlex Switch (G) for 2 seconds disables the EcoFlex system. The only way to re-enable is to push the EcoFlex Switch (G) again. Cycling
the Key Switch (A) does not re-enable the system. The EcoFlex system will only function if the Scrub System (I) has been enabled.
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. 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 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 (D7) turns on in the Display Panel when the switch is activated on "EcoFlex" models. The Hour Meter
(J2) momentarily fl ashes each letter of the word FULL over and over on "Standard" models.
12
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.
13
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 (27) from
its hanger and 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 (27)
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 (27) cap is properly seated or the machine will not pick-up water correctly. When the batteries
require recharging the Battery Indicator (G1) will fl ash red 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.
SERVICE NOTE: Refer to the service manual for detailed functional descriptions of all controls and optional programmability.
