AFTER USE
1 When finished scrubbing, press the Scrub Off Switch (E). This will automatically raise, retract and stop all the machine systems (brush, squeegee, vacuum,
solution and detergent (EDS models)). Then drive the machine to a service area for daily maintenance and review of other needed service up keep.
2 To empty the solution tank, remove the Solution Drain Hose (4) from it’s storage clamp. Direct the hose to a designated “DISPOSAL SITE” and remove the
plug. Rinse the tank with clean water.
3 To empty the recovery tank, pull the Recovery Tank Drain Hose (19) from its storage area. Direct the hose to a designated “DISPOSAL SITE” and remove the
plug (hold the end of the hose above the water level in the tank to avoid sudden, uncontrolled flow of waste water). The Recovery Tank Drain Hose can be
squeezed to regulate the flow. Rinse the recovery tank with clean water. Inspect the recovery and vacuum hoses; replace if kinked or damaged.
4 Remove the brushes or pad holders. Rinse the brushes or pads in warm water and hang up to dry.
5 Remove the squeegee, rinse it with warm water and re-install on mount.

FUNCTIONAL DESCRIPTION OF CONTROL PANEL SWITCHES:
The controls on your rider scrubber were designed with one touch operation in mind. For single pass scrubbing the user can simply depress one
switch and all systems on the machine will be ready to go. For most single-pass scrubbing operations, the operator should only need to use the
middle switches on the control panel. These are the red Scrub OFF and the green Scrub ON/Pressure increase switches.
(A) Key Switch – Main power switch, when turned on controls the battery input to the machine’s main control board and the wheel drive speed
control.
(B) Traction Control Switch - Pressing this switch when the unit is in a scrub mode will cause the following to occur.
• The torque value of the wheel drive motor is reduced to minimize drive wheel slippage thus providing better traction.
(D) Scrub ON/Pressure increase Switch (Auto Scrub Mode) – If the scrub system is off, pressing this switch once will cause the following to
occur:
• The scrub system will be enabled with the scrub pressure set to the #1 normal setting and the scrub deck and squeegee will automatically be
lowered. On the cylindrical units the side brooms will also be lowered to the floor. Note press the switch twice for #2 heavy scrub setting and three
times for the #3 extreme scrub setting.
• The vacuum system will be enabled.
• The solution system will be enabled.
• As soon as the throttle (operator foot pedal) is moved from its neutral position the scrub brushes will start turning and the vacuum will turn on. If
the direction is forward the solution will also start automatically. If the direction is reverse, the solution flow will be stopped. When the unit is already
scrubbing additional activating of the switch will increase to the next highest scrub pressure setting (cycling through example 1,2,3 back to 1), at the
same time the control panel display will show the correct changed value chosen.
• Special Operational Note: The solution, vacuum and detergent systems are automatically enabled when the scrub ON switch is pressed. Any
individual system can be turned OFF or back ON by simply pressing its switch at any time during scrubbing.
(E) Scrub OFF Switch – Pressing this switch when the unit is in a scrub mode will cause the following to occur:
• The scrub brushes will turn off and the scrub deck will be raised to the up position and on cylindrical models the side brooms will also be raised.
• The solution will be stopped.
• The vacuum switch indicator light will start to blink the squeegee will be raised to its up position after 4-5 seconds and the vacuum motor will shut
off after a 10 second delay. Pressing the switch a second time before completing the vacuum delay will turn off the vacuum motor immediately.
(F) Solution Switch –
• Press the solution switch and hold for approximately 5 seconds to pre-wet the floor. Note this must be done prior to pressing the Scrub ON switch
(D).
• When operating in any (3) of the auto scrub pressure modes both the standard solution and detergent (EDS models) systems have 3 flow rate
presets that coincide with the 3 scrub modes.
• Note: There is a solution flow rate over-ride function if the operator needs to set a different flow rate without increasing scrub pressure. Hold the
solution switch (F) for 2 seconds (solution indicator will start flashing) and then let go. You then have 3 seconds to set a different flow rate by pressing
the switch repeatedly until the flow indicator (K1) shows the rate needed. The machine is programmed for two additional dosage levels plus the 3
normal default values for a total of 5 flow volumes. If any scrub pressure change is made in the solution over-ride mode it will reset to its default
solution output.
(G) Vacuum Switch – This switch is used to select the mode of operation for the vacuum recovery system. Following is an explanation of the
different operational modes and how they are selected.
• Scrub ON Auto Mode: Pressing the vacuum switch when scrubbing will raise the squeegee tool and the vacuum motor will run for additional 5-6
seconds then shut OFF. This mode is used when the operator desires to double-scrub (scrub without recovering the solution).
• Scrub OFF Mode: In this mode (non-scrubbing) when the vacuum switch is pressed the squeegee is lowered and the vacuum motor will run
continuously, no throttle pedal input needed. When the machine is moved into reverse the squeegee will be raised and lowered when moving the
machine forward. This mode is used to pickup water from the floor without selecting a scrub mode.
• Pressing the scrub OFF switch when the unit is in the auto scrub mode will cause the following to occur: The squeegee will raise and the vacuum
motor will go into a 10sec time delay and then shut off. Press the vacuum switch again before the time delay has ended will shut the vacuum off
immediately. See the scrub OFF (E) explanation above for all the complete scrub OFF functions.
• Note: When the recovery tank becomes full (when in the auto scrub mode) the vacuum motor shuts off and all the other systems except the drive
motor, the full tank icon is displayed on the dash panel.
(H) Horn Switch – Pressing this switch will activate (turn ON) the horn.
(I) Wand Switch – The switch is used when the optional (external) vacuum scrub wand is used. Pressing this switch will turn ON the vacuum motor
and optional solution pump continuously until the switch is pressed again to turn it OFF. Note: When operating in the wand mode and the vacuum
switch is pressed the vacuum will turn off in 5-6 seconds (time delay).

FUNCTIONAL DESCRIPTION OF CONTROL PANEL SWITCHES:
(J) Detergent System ON/OFF switch – Pressing this switch will turn ON or OFF the detergent option. See the main programming options in this
manual to select (activate) the onboard detergent detergent delivery system.
(C) Side Broom ON/Down Switch and (L) Side Broom OFF/UP Switch - These switches are only functional on the cylindrical scrub models
equipped with side brooms. When the scrub system is ON the side brooms are lowered to the floor to the same position when the scrub system
was last turned OFF (auto memory operating position). Note: There is a broom height over-ride adjustment function for raising or lowering the side
brooms to obtain the corrected broom contact patterns in compensating for normal broom wear. To enter to adjust hold either the down (C) or up
(L) side broom switches for 2-3 seconds (both switch indicators will flash) and then let go. You then have 3 seconds to press either switch to reset
the needed broom(s) working pattern position. The machine is now reprogrammed to work with the new setting.
(M) Scrub Speed Switch – When the machine is operating in any one of its scrub settings the machine’s travel speed is reduced to the speed
controllers pre-programmed 70% of its maximum transport speed. Pressing the switch increases (over-rides) the 70% max programmed scrub
speed to 100% of transport speed.

FUNCTIONAL OVERVIEW
The plastic (polyethylene) molded main body structure fulfills three (design) functional uses. They are the platform for the operator’s seat, mount location cavity for
the electrical panel and as the storage tank for the machine’s scrubbing solution. The solution tank fill capacity is 70 gallons (265 L). See Figure 1.1 & 1.2. Plumbed
into the bottom of the solution tank outlet is a tee fitting and combined shut-off valve (A) (ball valve). The right branch of the tee fitting has attached a short flexible
hose (B) to be used to drain the tank for system maintenance. The left branch of the shut-off valve feeds solution to a serviceable filter (C) that keeps debris from
entering the solenoid valve.
The standard model machine’s solution system uses an electrically activated solenoid valve. The solution in the tank is fed by gravity to the L1 valve and its output
volume is controlled by the A2 board’s programmable capability. The L1 solenoid’s coil circuit opens and closes (pulsing ON & OFF) pulling its valve diaphragm ON
and OFF its seat. This is how the (3) different auto flow volumes are managed. Note on the EDS systems the L1 valve is not pulsed it is just turned ON and OFF
and a separate solution pump is turn ON and OFF (pulsed) by the A2 control board’s program. Note: Reference the EDS manual section for its detailed component
layout and operational explanation.
During machine scrubbing the solution system’s Auto Mode is pre-selected and works in conjunction with the (A1) wheel drive speed controller and R1 throttle pot
input, this is what activates the main control board’s outputs to turn ON and OFF the L1 solenoid valve. The solution then flows to the scrub brushes any time the
scrub deck is lowered and the drive pedal is pushed into the forward drive position. Note: When the dash panel solution switch is pressed (turned off), no flow can
occur regardless of the drive pedal Fwd position and the scrub deck being down.
Threaded into the tank bottom is the S5 liquid level tank switch (float switch). When the solution level drops to about 2-3 inches left in the tank it signals the main
control board of a low level condition. The operator will then notice on the dash panel that its solution indicator light is flashing ON & OFF. Note: The machine will
continue to function, the flashing indicator is just a low level reminder.

TROUBLESHOOTING GUIDE
Problem Possible Cause
Inadequate or no solution flow
- on standard models
No solution in the tank
Solution shut-off valve lever is in the off position
Clogged solution filter, valves, hoses & solution delivery trough (cyl.)
Defective solution solenoid valve (L1)
Solution system fault in the main controller A2*
Inadequate or no solution flow
- on EDS systems See EDS system section for its troubleshooting guide
*Reference the Main Control Board Troubleshooting Guide in the Electrical System of this manual for further information.
SOLUTION SYSTEM MAINTENANCE
• Solution Tank: See Figure 1.1. Weekly empty the solution tank; remove the solution Drain Hose (B) from its storage area (located above the left rear tire). Direct
the hose to a designated “Disposal Site” and flush the tank with clean water.
• Solution Filter: Remove and clean the inline Solution Filter (C). To access the filter housing for removal, work underneath the middle left side chassis solution
tank. No tools are needed to remove the filter (hand tighten only). Service Tip: The manual solution ball valve (shut-off) handle must be placed in the full
OFF position. This prevents loss of solution when servicing the filter strainer with a partial or full tank.
• Solution Delivery Trough: Note on the cylindrical scrub deck clean the holes in the delivery trough to assure even distribution of solution.
