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.
To Scrub...
Follow the instructions in "preparing the machine for use" section of this manual.
1 See Figure 8. While seated on the machine, adjust the seat and steering wheel to a comfortable operating position using the adjustment controls (23) and
(5).
2 Turn the Master Key Switch (A) ON (I). This will display the control panel indicator lights. Reference the Battery Condition Indicator (K5) and Hour Meter (K3)
before proceeding.
3 Release the Parking Brake (6). To transport the machine to the work area, apply even pressure with your foot on the front of the Drive Pedal (8) 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 the Solution Switch (F) and hold for 5 seconds to pre-wet the oor. NOTE: This will help prevent scarring of the oor surface when starting to scrub
with dry brushes. This must be done prior to pressing the Scrub ON Switch (D).
5 Press the Scrub ON Switch (D) once for Regular Scrub, twice for Heavy Scrub or three times for Extreme Scrub mode. Both the solution ow and detergent
(Eco Flex models) ow have 3 presets that coincide with the 3 scrub modes (see Control Panel).
NOTE: There is a solution ow rate override function if you wish to increase solution ow without increasing scrub pressure. Hold the Solution Switch (F) for
3 seconds (solution indicator will start ashing) and then let go. You then have 3 seconds to set a different ow rate by simply pressing the Solution Switch
(F) repeatedly until the Solution Flow Indicator (K1) shows the rate you desire (1-5 / see Control Panel). Any subsequent scrub pressure adjustments will
reset the solution ow rate to default.
6 When the Scrub ON Switch (D) is selected, the brushes, squeegee and side brooms (cylindrical models) are automatically lowered to the oor. The scrub,
solution, vacuum, detergent (EcoFlex models) and side brooms (cylindrical models) systems are all automatically enabled and will start when the Drive Pedal
(8) 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.
7 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 ow when necessary according to the condition of the oor.
NOTE: The maximum scrub speed can be increased by pressing the Scrub Speed Switch (L). The default maximum scrub speed is less than the maximum
transport speed. Pressing this switch overrides this default and allows scrubbing at the maximum transport speed.
If scrubbing on a smooth oor surface or double-scrubbing turning on the Traction Control™ button (B) regulates the drive wheel torque providing increased
control and enhanced traction on the oor.
The side broom height can be adjusted. See the "Side Broom Maintenance" section of this manual.
CAUTION!
To avoid damaging the 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 The machine defaults to the last cleaning mode used Minimum or Maximum Concentration Detergent (if detergent is installed and was activated). Press the
Burst of Power Switch (G) to override the current cleaning mode and temporarily increase scrub pressure, solution ow and the detergent ratio (unless in
Maximum Concentration). This will cause the indicator to ash for one minute, solution ow rate will increase to the next level, scrub pressure will increase to
the next level and the detergent ratio will be at the Maximum Concentration level (detergent system will be turned on if it was off).
NOTE: Pressing and holding the Burst of Power Switch (G) for 2 seconds changes between the Minimum and Maximum Concentration operating modes.
The EcoFlex system will only function if the scrub system (D) has been enabled.
10 For extremely dirty 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 rst pass the squeegee is in the up position (press the Vacuum/Wand Switch (I) to raise the squeegee). This
allows the cleaning solution to remain on the oor to work longer. The nal pass is made over the same area, with the squeegee lowered to pick up the
accumulated solution.
11 The recovery tank has a shut-off oat (15) that causes ALL systems to turn OFF except the drive system when the recovery tank is full. When this oat is
activated, the recovery tank must be emptied. The machine will not pick up water or scrub with the oat activated.
NOTE: All other indicators vanish and a "Recovery Tank FULL" Indicator (K7) appears on the Display Panel when the oat is activated. If the control
repeatedly gives a full indication when the tank is not full, the automatic shut-off feature can be disabled, have a quali ed service technician refer to the
service manual to perform this function.
12 When the operator wants to stop scrubbing or the recovery tank is full, press the Scrub OFF Switch (E) once. This will automatically stop the scrub brushes
and solution 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).
13 Drive the machine to a designated waste water "DISPOSAL SITE" and empty the recovery tank. To empty, pull the Drain Hose (19) from its rear storage area,
then remove the plug (hold the end of the hose above the water level in the tank to avoid sudden, uncontrolled ow of waste water). Re ll the solution tank
and continue scrubbing.
NOTE: Make sure the Recovery Tank Cover (1) and the Recovery Tank Drain Hose (19) cap are properly seated or the machine will not pick-up water correctly.
When the batteries require recharging the Battery LOW Indicator (K8) will come on, the scrub brushes and solution ow will stop 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. Transport the machine to a service area and recharge the batteries
according to the instructions in the Battery section of this manual.
