SCRUBBING
Follow the instructions in preparing the machine for use section of this manual.
1 While seated on the machine, adjust the seat and steering wheel to a comfortable operating position using the adjustment controls (PP) and (LL) .
2 Release the Parking Brake (OO) . To transport the machine to the work area, apply even pressure with your foot on the front of the Drive Pedal (MM) to
go forward or the rear of the pedal for reverse. Vary the pressure on the foot pedal to obtain the desired speed.
3 Adjust the Solution Flow Control Lever (EE) to about 1/4 to 1/3 (40%-100% on AXP/EDS) open position. The adjustment can be changed to allow
variable solution fl ow for different types of fl oors to be scrubbed. Example: A rough or absorbent fl oor surface, such as un fi nished concrete will require
more solution than a smooth fi nished fl oor.
4 Press the Solution Switch (K) and hold for 5 seconds. This is done to pre-wet the fl oor. Note: This will help prevent scarring of the fl oor surface when
starting to scrub with dry brushes.
5 Press the Scrub Pressure Decrease Switch (H) or the Scrub Pressure Increase Switch (I) to activate the scrub system.
6 When the Scrub Pressure Decrease Switch (H) or the Scrub Pressure Increase Switch (I) are selected, the brushes and squeegee are automatically
lowered to the fl oor. The machine’s scrub brush rotation, solution system fl ow, detergent fl ow(AXP/EDS only) and vacuum starts when the Drive
Pedal (MM) is activated. Note: When operating the machine in reverse, only the brushes will rotate, the solution and detergent(AXP/EDS only) is
automatically shut off and the squeegee raises.
7 Begin scrubbing by driving the machine forward in a straight line at a normal walking speed and overlap each path by 6 inches (15 cm). Adjust the
machine speed and solution
fl ow according to the condition of the fl oor.
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 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 Switch (N) 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 an automatic vacuum shut-off to prevent solution from entering the vacuum system when the recovery tank is full. When the
vacuum shut-off is activated, the control system will shut down the vacuum system. The Recovery Tank FULL Indicator (M) will light. When the vacuum
shut-off is activated, the recovery tank must be emptied.
11 When the operator wants to stop scrubbing or the recovery tank is full, press the Scrub System OFF Switch (O) once. This will automatically stop the
scrub brushes, solution fl ow, detergent fl ow(AXP/EDS only) and the scrub deck will raise UP. NOTE: the vacuum/squeegee system will not be turned
off when the switch is only pressed once. This is to allow any remaining water to be picked up without turning the vacuum back on. Press the switch a
second time and the squeegee will raise and the vacuum will stop after a 10 second delay.
12 See the instructions below for emptying the recovery tank. Re fi ll the solution tank and continue scrubbing.
EMPTYING THE RECOVERY TANK
1 Drive the machine to a designated waste water “DISPOSAL SITE”.
2 To empty, pull the Drain Hose (5) from its storage area, hold the end of the hose above the water level in the tank to avoid sudden, uncontrolled fl ow of
waste water and open the cap. NOTE: You can also pinch the fl exible end of the hose to control waste water fl ow as shown below.
3 Flush the tank and drain hose with clean water.
4 Reclose the cap and return the hose to its storage area.
SERVICE NOTE: The recovery tank can be tipped out to the side for cleaning after emptying. Release the Latch (6) at the front of the tank and then pull
out on the tank with grip (26) until the tank reaches the end of its tether. Remove the recovery tank lid for easier cleaning. The recovery tank can also be
removed for cleaning. You will need to disconnect the wire harness and tether fi rst and then use at least 2 people to lift off.
SERVICE NOTE: Refer to the service manual for detailed functional descriptions of all controls and optional programmability.
