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. Clean only
while ascending (driving up) the ramp.
To Scrub...
Follow the instructions in “preparing the machine for use” section
of this manual.
1 See Figure 4. While seated on the machine, adjust the
steering wheel to a comfortable position using the Steering
Wheel Tilt Adjust Knob (23). The seat can be adjusted if
necessary by tipping up the seat and using the adjustment
knob (18).
2 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.
3 To transport the machine to the work area, apply even
pressure with your foot on the front of the Drive Pedal (3)
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 and hold the Solution Switch (C) to pre-wet the fl oor,
solution will be dispensed while the switch is held. NOTE:
This will help prevent scarring of the fl oor surface when
starting to scrub with dry brushes. This must be done prior to
pressing the Scrub ON Switch (H).
5 Press the Scrub ON/OFF Switch (H), the scrub deck and
squeegee will automatically be lowered to the fl oor. The
scrub, vacuum, solution and detergent (EDS models)
systems all start when the Drive Pedal (3) is activated.
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 Normal, Heavy and Extreme Scrub modes.
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 (EDS
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.
NOTE: When operating the machine in reverse the
squeegee automatically raises.
6 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 fl ow when
necessary according to the condition of the fl oor.
CAUTION!
To avoid damaging the fl oor, keep the machine moving while the
brushes are turning.
7 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.
8 The machine defaults to the EverGreen cleaning mode
(EverGreen Switch Indicator is lit GREEN) conserving solution
and detergent. Press the EverGreen Switch (J) to override
the EverGreen cleaning mode and temporarily increase scrub
pressure, solution fl ow and the detergent percentage. 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 percentage will increase to the
next larger percentage.
9 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 (press
the Vacuum/Wand Switch (L) to raise the squeegee). 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.
10 The recovery tank has a shut-off fl oat (29) 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) appears on the Display Panel when the fl oat is
activated.
11 When the operator wants to stop scrubbing or the recovery
tank is full, press the Scrub ON/OFF Switch (H) once. This will
automatically stop the scrub brushes and solution fl 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).
12 Drive the machine to a designated waste water “DISPOSAL
SITE” and empty the recovery tank. To empty, pull the Drain
Hose (31) 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 fl ow of waste water). Refi ll the solution
tank and continue scrubbing.
NOTE: Make sure the Recovery Tank Cover (26) and the Recovery
Tank Drain Hose (31) cap are properly seated or the machine will not
pick-up water correctly.
