SCRUBBING

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. Start the engine following the instructions in the appropriate "Starting the ...
Engine" section.
1 See Figure 5. While seated on the machine, adjust the seat and steering wheel to a comfortable operating position using the adjustment controls (18 & 27).
2 Release the Parking Brake (28). To transport the machine to the work area, apply even pressure with your foot on the front of the Drive Pedal (29) to go forward or the rear of
the pedal for reverse. Vary the pressure on the foot pedal to obtain the desired speed.
3 Press the Solution Switch (56) and hold for 5 seconds to pre-wet the fl oor. 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 (54).
4 Press the Scrub ON Switch (54) once for Light Scrub (1), twice for Medium Scrub (2) or three times for Heavy Scrub (3) mode. Both the solution fl ow and detergent (AXP
models) fl ow have 3 presets that coincide with the 3 scrub modes (see Display Panel (64)). The right side scrub brush pressure is also affected when pressing this switch.
NOTE: The solution fl ow rate can be overridden simply by pressing the Solution Flow Decrease or Increase Switches (56a / 56b). Any subsequent scrub pressure adjustments
will reset the solution fl ow rate to correspond with the scrub pressure.
NOTE: The scrub, solution, vacuum, detergent (AXP models) and side broom(s) / brush systems are automatically enabled when the Scrub ON Switch (54) is pressed.
Any individual system can be turned OFF or back ON by simply pressing its switch at any time during scrubbing. If you have installed the Extended Scrub Kit, it will not be
automatically activated. You must press the Extended Scrub Switch (60) to activate this system. The Extended Scrub system will not turn ON until the water level in the recovery
tank reaches a certain level and the clean solution has been used up.
5 When the Scrub ON Switch (54) is selected, the brushes, squeegee and side broom(s) / brush are automatically lowered to the fl oor. The scrub, solution, vacuum, detergent
(AXP models) and side broom(s) / brush systems all start when the Drive Pedal (29) is activated.
NOTE: When operating the machine in reverse the squeegee automatically raises and the solution fl ow will stop.
6 Begin scrubbing by driving the machine forward in a straight line at a normal walking speed and overlap each path by 2-3" (5.08-7.62cm). Adjust the machine speed and solution
fl ow when necessary according to the condition of the fl oor.
The side broom height can be adjusted by pressing the Side Broom DOWN and UP Switches (53a/53b). The side broom(s) will return to the last used position each time the
sweep system is turned on. The side brooms have a misting function (Dust Guard) (52) for use in dusty conditions. NOTE: The "Dust Guard" (52) comes on automatically
with the Side Brooms (53) but can be turned OFF by pressing (52). NOTE: If equipped with Extended Scrub, the "Dust Guard" will shut off when the machine runs out of clean
solution.
CAUTION!
To avoid damaging the fl oor, keep the machine moving while the brushes are turning (the brushes will turn OFF after a 2 second delay when the
drive pedal is placed in the neutral position).
Raise scrub deck and side scrub brush, if so equipped, when crossing speed bumps. Do not attempt to operate the scrub deck or side brush in the
down position when crossing speed bumps. Hydraulic pressure pushes down on the brushes and attempting to operate in the scrub mode over a
speed bump can cause damage to the machine.
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 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 (57) to raise the squeegee). This allows the cleaning solution to remain on the
fl oor to work longer. The Side Skirts (13 & 31) can also be raised for double scrubbing if needed with the Skirt Holders (20). The fi nal pass is made over the same area, with the
squeegee and skirts lowered to pick up the accumulated solution.
9 The recovery tank has a fl oat switch that causes ALL systems to turn OFF except the drive system when the recovery tank is full. When this fl oat switch is activated, the
recovery tank must be emptied. The machine will not pick up water or scrub with the fl oat switch activated.
NOTE: The Attention Indicator Light (66) will light up YELLOW and the Recovery Full Icon (66e) will display when the fl oat switch is activated. If the control repeatedly gives a
full indication when the tank is not full check to make sure the fl oat moves freely.
10 When the operator wants to stop scrubbing, press the Scrub OFF Switch (55) once. This will automatically stop the scrub brushes, side broom(s) / brush, solution fl ow and
detergent fl ow. The scrub deck and side broom(s) / brush 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).
11 Drive the machine to a designated waste water "DISPOSAL SITE" and empty the recovery tank. To empty, pull the Drain Hose (9) from its storage area, then remove the plug
(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 (9) can be squeezed to regulate
the fl ow. Refi ll the solution tank and continue scrubbing.
NOTE: Make sure the Recovery Tank Cover (4) and the Recovery Tank Drain Hose (9) cap are properly seated or the machine will not pick-up water correctly.
SERVICE NOTE: Refer to the service manual for optional programmability.
