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.
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. The Hour Meter will display for 5 seconds followed by the Battery
Indicator in the upper left on the Display Panel (D2).
3 To transport the machine to the work area, push the Drive Paddle (20) forward to go forward or pull the Drive Paddle (20) backward to move the machine in
reverse. Vary the pressure on the Drive Paddle (20) to obtain the desired speed.
NOTE: Speed Control Knob (21) is used to control the maximum speed in either forward or reverse.
Extracting
4a With scrub deck raised (OFF), press the orange Floor Mode Switch (K) until the display shows (D11). The Display (D11) is shown to indicate that Extract Mode
has been selected and also to alert the operator to connect the Vacuum Recovery Hose (30A) to the extractor shoe port for extracting. NOTE: The squeegee
can be removed if desired while extracting.
4b Press the green Scrub ON Switch (J) once for LIFT Extraction (D5) or twice for Restoration Extraction (D6) mode.
LIFT Low Moisture Mode: Lower solution fl ow, higher travel speed. Recommended for frequent cleaning and when fast dry times are required.
Restoration Mode: Higher solution fl ow, lower travel speed. Recommended for less frequent deep cleaning.
Once pressed, the scrub deck and extractor shoes will be lowered. NOTE: The solution, vacuum and detergent systems are automatically activated once the
green Scrub ON Switch (J) is pressed. Any individual system can be turned OFF or back ON by simply pressing its switch at any time while extracting.
4c When the Drive Paddle (20) is in the neutral position, the scrub, vacuum, solution and detergent systems are activated but not running. Grip the Operator
Control Handle (19) and push the Drive Paddle (20) forward to; start the scrub motors, start both vacuum motors, dispense solution/detergent, and to move the
machine forward. The Adphibian/AX 651 will move at a preprogrammed speed for optimum cleaning results. Press the Solution/Pre-Spray Switch (C) once to
turn OFF while making sharp turns. Pull the Drive Paddle (20) backward to move the machine in reverse. The brushes will run while moving the machine in
reverse, but solution and detergent will not be dispensed.
4d For extremely dirty fl oors, a one-pass extraction operation may not be satisfactory and a pre-spray operation may be required. See Pre-Spraying the Carpet in
the Preparing the Machine for Use section.
4e Watch the fl uid entering the Recovery Tank Dome Lid (3). If there is a large amount of suds in the recovery tank, add a defoamer chemical to the recovery
tank.
Scrubbing
4a With scrub deck raised (OFF), press the orange Floor Mode Switch (K) until the display shows (D12). The Display (D12) is shown to indicate that Scrub Mode
has been selected and also to alert the operator to connect the Vacuum Recovery Hose (30B) to the squeegee assembly for scrubbing.
4b Press and hold the Solution/Pre-Spray Switch (C) to pre-wet the fl oor, solution/detergant will be dispensed while switch is held. NOTE: This must be done prior
to pressing the green Scrub ON Switch (J).
4c Press the green Scrub ON Switch (J) once for Light Scrub [display will show (D15) and (D14)] or twice for Heavy Scrub Mode [display will show (D15) and
(D16)].
Once pressed, the scrub deck will be lowered (extractor shoes remain up). NOTE: The solution, vacuum and detergent systems are automatically activated
once the green Scrub ON Switch (J) is pressed. Any individual system can be turned OFF or back ON by simply pressing its switch at any time while
scrubbing.
4d Lower the squeegee assembly using the Squeegee Raise/Lower Lever (36).
4e When the Drive Paddle (20) is in the neutral position, the scrub, vacuum, solution and detergent systems are activated but not running. Grip the Operator
Control Handle (19) and push the Drive Paddle (20) forward to; start the scrub motors, start one vacuum motor, dispense solution/detergent, and to move
the machine forward. For best results, move the machine at a slow walking speed. Press the Solution/Pre-Spray Switch (C) once to turn OFF while making
sharp turns. Pull the Drive Paddle (20) backward to move the machine in reverse. The brushes will run while moving the machine in reverse, but solution and
detergent will not be dispensed.
4f 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.
CAUTION!
To avoid damaging the fl oor, keep the machine moving while the brushes are turning.
5 The recovery tank has an automatic shut-off switch that turns ALL system 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 (D9) turns on in the Display Panel when the switch is activated.
6 When the operator wants to stop scrubbing/extracting or the recovery tank is full, press the red 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 motor(s) will stop after a 10 second delay, this is to allow any remaining
water left in the vacuum hose to be picked up rather than draining back onto the fl oor.
7 Raise the squeegee if necessary and drive the machine to a designated wastewater "DISPOSAL SITE" and empty the recovery tank. To empty, pull the
Recovery Tank Drain Hose (25) from its hanger, then open the Cap (32) (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 (25) can be squeezed to regulate the fl ow. Refi ll the solution tank and continue cleaning.
NOTE: Make sure the Recovery Tank Cover (3) and the Recovery Tank Drain Hose Cap (32) are properly seated or the machine will not pick-up water correctly. When the batteries
require recharging the Battery Low Indicator (D10) will come on and the vacuum motor(s) will shut off after 30 seconds. Transport the machine to a service area and fully recharge the
batteries according to the instructions in the Battery section of this manual.
