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.
To Scrub...
1 Follow the instructions in the "Preparing the Machine for Use" section of this manual.
2a SC750, SC800 models: 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) before proceeding.
3a To transport the machine to the work area, push the Drive Paddle (29) forward to go forward or pull the Drive Paddle (29) backward to move the machine in reverse. Vary the
pressure on the Drive Paddle (29) to obtain the desired speed.
NOTE: Speed Control Knob (30) is used to control the maximum speed in either forward or reverse.
4a Press and hold the Solution Switch (C) for 5 seconds to pre-wet the fl oor. NOTE: This must be done prior to pressing the Scrub ON/OFF Switch (H).
5a Press the Scrub ON/OFF Switch (H), 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 Regular and Heavy Scrub modes. Only one pressure sensing is available for cylindrical machines.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 (EcoFlex 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. No further action is required other than lowering the squeegee (12).
6a Lower the squeegee with the Squeegee Raise / Lower Lever (14).
7a When the Drive Paddle (29) is in the neutral position, the scrub, vacuum, solution and detergent (EcoFlex models) systems are activated but not running. Grip the Operator
Control Handle (2) and push the Drive Paddle (29) forward 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 the Solution Switch (C) once to turn OFF while making sharp turns. Pull the Drive Paddle (29) 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.
2b ST models: Turn the Master Key Switch (A) ON (I). This will display the control panel indicator lights, reference the Battery Indicator (E) before proceeding.
3b To transport the machine to the work area, push either of the Palm Buttons (32) to go forward or press either Palm Button (32) and the Reverse Button (31) to move the machine
in reverse.
NOTE: Speed Control Knob (30) is used to control the maximum speed in either forward or reverse.
4b 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 (D).
5b Press the Scrub ON Switch (D) once for Regular Scrub Pressure (one scrub pressure indicator lit) or twice for Heavy Scrub Pressure (two scrub pressure indicators lit). Only one
pressure sensing is available for cylindrical machines. 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 and vacuum systems are automatically activated when the Scrub ON Switch (D) is pressed. No further action is required other than lowering the squeegee
(12). Any individual system can be turned OFF or back ON by simply pressing its switch at any time during scrubbing.
6b Lower the squeegee with the Squeegee Raise / Lower Lever (14).
7b When the Palm Buttons (32) are not being pressed (machine stationary), the scrub, vacuum and solution systems are activated but not running. Grip the Operator Control
Handle (2) and press either of the Palm Buttons (32) to start the scrub, vacuum, solution, and to move the machine forward. For best results, move the machine at a slow
walking speed. Press either palm button plus the reverse button to move the machine in reverse. The brushes will run while moving the machine in reverse, but solution 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 (J) 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 (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 EcoFlex 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
1:400)
. Once the desired ratio is displayed on the screen (F5), stop and it will lock in after 5 seconds.
NOTE: Pressing and holding the EcoFlex Switch (J) for 2 seconds disables the EcoFlex system. The only way to re-enable is to push the EcoFlex Switch (J) again. Cycling the
Key Switch (A) does not re-enable the system. The EcoFlex system will only function if the Scrub System (H) 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.
11a SC750, SC800 models: The recovery tank has a shut-off fl oat (4) 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) turns on in the Display Panel when the switch is activated on "EcoFlex" models.
11b SC750 ST, SC800 ST models: The recovery tank has a shut-off fl oat (4) 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.
12 When the operator wants to stop scrubbing or the recovery tank is full;
SC750, SC800 models: Press the Scrub ON/OFF Switch (H) once. This will automatically stop the scrub motors and the solution fl ow and the deck will raise to its upper limit.
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.
SC750 ST, SC800 ST models: Press the Scrub ON/OFF Switch (D) once to the down position when it is in the regular scrub mode. This will automatically stop the scrub motors
and the solution fl ow and the deck will raise to its upper limit. 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 with the Squeegee Raise / Lower Lever (14). and drive the machine to a designated wastewater "DISPOSAL SITE" and empty the recovery tank. To empty,
pull the Recovery Tank Drain Hose (24) 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 (24) can be squeezed to regulate the fl ow. Refi ll the solution tank and continue scrubbing.
