OPERATING THE MACHINE (DISC & CYLINDRICAL)
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.
To Scrub...
Follow the instructions in "Starting the Machine" section and drive the machine to the start point for cleaning.
See Figure 3-1. Press the One-Touch Scrub ON Switch (M) once for Regular Scrub. Press the Scrub Pressure Increase Switch (M+) once for Heavy Scrub
1
or twice for Extreme Scrub mode. The solution flow has settings that coincide with the scrub pressure, it will increase and decrease along with the scrub
pressure.
NOTE: The solution flow rate can also be increased or decreased independently of the scrub pressure by pressing the Solution Flow Increase Switch (F+)
or Solution Flow Decrease Switch (F-), observe the Solution Flow Rate Bar Graph (C10). Any subsequent scrub pressure adjustments will reset the solution
flow rate to default.
2
When the One-Touch Scrub ON Switch (M) is selected, the brushes and squeegee are automatically lowered to the floor. The scrub, solution, vacuum and
detergent (EcoFlex models) systems are all automatically enabled and will start when the Drive Pedal (3) is activated. 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.
Detergent: See "Detergent System Preparation and Use (EcoFlex) for detailed information regarding adjustment and use.
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 (50-75 mm). Adjust the
machine speed and solution flow when necessary according to the condition of the floor. Push the Timed Solution Off Paddle (O) before entering a turn to
temporarily turn off the solution flow. The Solution Flow Rate Bar Graph (C10) will be replaced by a 5 second countdown timer showing how long the solution
flow will be off. Push paddle again before timer runs out to cancel solution off.
NOTE: While scrubbing the maximum machine speed can be set by pressing the Speed Limiter Switch (L). Adjust the machine to the desired speed using
the Drive Pedal (3) then press the Speed Limiter Switch (N). The operator can now press the pedal all the way forward without increasing the machine speed
thereby reducing operator fatigue. The machine Speed (C5) is shown on the display. The speed limit will be in effect every time you scrub until the speed
limiter switch is pressed again (while scrubbing) to disable the speed limit.
CAUTION!
To avoid damaging the floor, keep the machine moving while the brushes are turning.
4
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.
5
For extremely dirty floors, 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 first pass the squeegee (33) and scrub deck blades (AA) are in the up position see
Position. Press the Vacuum Switch (G) to raise the squeegee.
This allows the cleaning solution to remain on the floor to work longer. The final pass is made over the same area, with the squeegee and side blades
lowered to pick up the accumulated solution
The recovery tank has a Shutoff Float (25). When the tank is full the float is activated and closes the inlet so no more water can enter the recovery tank.
6
When the float is activated the operator may notice a change in the sound of the vacuum motor or will notice machine is no longer picking up water. When
the shutoff float is activated, the recovery tank must be emptied. The machine will not pick up water with the float activated but no machine functions will turn
off.
7
When the operator wants to stop scrubbing or the recovery tank is full, press the One-Touch Scrub Switch (M) once. This will automatically stop the scrub
brushes and solution flow 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
(this is to allow any remaining water to be picked up without turning the vacuum back on). When scrub is turned off the speed limit is also turned off and
machine speed will go back to normal operation.
8
Drive the machine to a designated waste water "DISPOSAL SITE" and empty the recovery tank. To empty, pull the Recovery Tank Drain Hose (28) from its
storage area. Hold the end of the hose above the water level in the tank then unscrew the cap. Squeeze the hose as shown until the hose is near the drain
to avoid sudden uncontrolled flow of waste water. Screw on the cap and push the recovery tank drain hose back into its storage area. Refill the solution tank
and continue scrubbing.
NOTE: Make sure the Recovery Tank Cover (24) and the cap on the Recovery Tank Drain Hose (28) are properly seated or the machine will not pick-up water
correctly.
If the batteries become discharged to the low voltage cutout threshold the Battery Low Voltage Indicator (C14) will come on, 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. Recharge the batteries according to the instructions in "Charging Wet Batteries" or "Charging Gel/AGM (VRLA) Batteries" sections of this
manual.
