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 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 (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 ow and
detergent (EcoFlex models) 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 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 ow rate to correspond with the scrub pressure.
NOTE: The scrub, solution, vacuum, detergent (EcoFlex 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 oor. The scrub, solution,
vacuum, detergent (EcoFlex 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 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 ow when necessary according to the condition of the 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 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 The machine defaults to the EcoFlex cleaning mode (if detergent is installed) (EcoFlex Switch Indicator is lit) conserving solution and detergent. Press the
Burst of Power Switch (57) to override the EcoFlex cleaning mode and temporarily increase scrub pressure, solution ow and the detergent ratio. 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 increase to the next higher ratio from the last one used (detergent system will be turned on if it was off).
NOTE: Pressing and holding the Burst of Power Switch (57) for 2 seconds disables the EcoFlex system. The only way to re-enable is to push the Burst of
Power Switch (57) again. Cycling the Key Switch (50) does not re-enable the system. The EcoFlex system will only function if the Scrub System (54) has
been enabled.
9 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 Switch (58) to raise the squeegee). This allows
the cleaning solution to remain on the oor to work longer. The Side Skirts (13 & 31) can also be raised for double scrubbing if needed with the Skirt Holders
(20). The nal pass is made over the same area, with the squeegee and skirts lowered to pick up the accumulated solution.
10 The recovery tank has a oat switch that causes ALL systems to turn OFF except the drive system when the recovery tank is full. When this oat switch is
activated, the recovery tank must be emptied. The machine will not pick up water or scrub with the oat switch activated.
NOTE: The Attention Indicator Light (66) will light up YELLOW and the Recovery Full Icon (66e) will display when the oat switch is activated. If the control
repeatedly gives a full indication when the tank is not full check to make sure the oat moves freely.
11 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 ow and detergent 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).
12 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 ow of waste water). The Recovery Tank Drain
Hose (9) can be squeezed to regulate the ow. Re 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.
