INSTRUCTIONS FOR USEA- ENGLISH
OPERATING THE MACHINE
WARNING!
Be sure you understand the operator controls and their functions.
While on ramps or inclines, avoid sudden stops. Avoid abrupt sharp turns. Use low speed down ramps.
To Scrub...
Follow the instructions in “Preparing the Machine for Use” section of this manual.
1 See Figure 6. Step onto the Platform (20) compressing Operator’s Presence Pedal (19). NOTE: Do not press the Go Pedal (18) until you are ready to move
the machine.
2 Turn the Key Switch (A) ON (I). Wait a few seconds for the start-up sequence to finish. The graphic display (F) will show the information screen [2].
Reference the Battery Charge Level Indicator (F6) before proceeding.
3 To transport the machine to the work area, first push the Forward Drive Switch (L) or Reverse Drive Switch (N) to select the direction of travel and then apply
pressure with your foot on the Go Pedal (18).
An audible alert from the horn will sound in reverse. Adjust machine speed by rotating the SpeedAdjustment Knob (K) clockwise to go faster or
counterclockwise to go slower.
4 Press and hold the Solution Switch (S) to pre-wet the floor, solution will be dispensed at the HIGH rate while the switch is held. NOTE: This will help prevent
scarring of the floor surface when starting to scrub with dry brushes. This can only be done prior to pressing the Scrub ON/OFF Switch (I).
5Press the Scrub ON/OFF Switch (I). The graphic display (F) will change to the scrubbing screen [1]. The scrub deck and squeegee will be lowered to the
floor. The scrub, vacuum and solution systems are enabled and will all start when the Go Pedal (18) is activated. The scrub parameters are saved after each
use. When the key is turned ON and the scrub button is pressed the scrub parameters (vacuum power, solution flow rate and scrub pressure setting) will all
be remembered from previous use.
Scrub: Each press of the Brush Pressure Switch (P) will change between STANDARD pressure ((F3) bottom box filled top box empty) and EXTRApressure
((F3) both bottom and top boxes filled). The scrub system can only be turned OFF by pressing the Scrub Switch (I).
Solution: The solution flow rate can be changed independently of the scrub pressure by pressing the Solution Switch (S). Each press of the switch will cycle
between LOW, MEDIUM, HIGH, OFF and back to LOW. LOW is indicated when (F2) displays bottom box filled, MEDIUM is indicated when (F2) displays
bottom and middle boxes filled, HIGH is indicated when (F2) displays all three boxes filled, and OFF is indicated when (F2) displays all three boxes empty.
Vacuum: The vacuum level can be changed independently. Each press of the Vacuum Switch (U) will cycle between LOW, HIGH, OFF and back to LOW.
LOW is indicated when Vacuum Level Bar Graph (F1) displays bottom box filled, HIGH is indicated when (F1) displays both bottom and top boxes filled.
OFF is indicated when (F1) displays both bottom and top boxes empty. NOTE: To pick up solution without scrubbing, press the Vacuum Switch (U) while in
transport mode. This will cause the squeegee to lower and the vac motor to turn ON at the LOW level.
6 Daily Scrub: Begin scrubbing by driving the machine forward in a straight line at a safe speed and overlap each path by 2-3 inches (50-75 mm). Adjust the
machine speed, scrub pressure and solution flow when necessary according to the condition of the floor. NOTE: The machine speed can be adjusted by
rotating the SpeedAdjustment Knob (K) clockwise to go faster or counterclockwise to go slower.
CAUTION!
To avoid damaging the floor, only start and stop the scrubbing function while the machine is in motion.
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 floors, 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 first pass the squeegee is in the up position. Lift up the squeegee assembly and rotate the double scrub
bracket (AA) down, to hold the squeegee off the floor. This allows the cleaning solution to remain on the floor to work longer. The final pass is made over the
same area, with the squeegee lowered to pick up the accumulated solution.
9 The recovery tank has a shut-off float (14) that causes a change in pitch in the vac motor. When this float is activated, the recovery tank must be emptied.
The machine will not pick up water with the float activated.
10 When the operator wants to stop scrubbing:
Press the Scrub Switch (I) once. This will automatically stop the scrub brushes and solution flow and the scrub deck will raise up. The squeegee will raise up
after a brief delay with the scrub deck and the vacuum will stop after a brief time delay (this is to allow any remaining water to be picked up without turning the
vacuum back on) if the vacuum switch is pressed during this time delay the vacuum will turn off.
11 Drive the machine to a designated waste water “DISPOSALSITE” and empty the recovery tank. To empty, pull the Recovery Tank Drain Hose (30) from its
rear storage area, then unscrew the cap (hold the end of the hose above the water level in the tank to avoid sudden, uncontrolled flow of waste water). The
drain hose can be squeezed to regulate the flow. Unlatch (29) and lift open the Recovery Tank Cover (13) to inspect and empty the Debris Catch Tray (16) in
the recovery tank. Refill the solution tank and continue scrubbing.
NOTE: Make sure the Recovery Tank Cover (13) and the Recovery Tank Drain Hose (30) cap are properly seated or the machine will not pick-up water correctly.
When the batteries require recharging the Battery Low Voltage Screen [3] will come on. Then the scrub brushes and solution flow will stop and the scrub deck will
raise up. Once the battery voltage drops below a second cutoff level the squeegee will raise up and the vacuum will stop after a brief delay. Transport the machine
to a service area and recharge the batteries according to the instructions in the Battery section of this manual.

CHARGING GEL/AGM (VRLA) BATTERIES
Charge the batteries each time the machine is used or when the Battery Charge Level Indicator (F6) is reading less than full.
WARNING!
Charge batteries in a well-ventilated area. If battery acid makes contact with your skin, flush the affected area with water for 5
minutes and seek medical attention.
Do not smoke while servicing the batteries.
FIGURE 9
When Servicing Batteries...
*Remove all jewelry
*Do not smoke
*Wear safety glasses, rubber gloves and a rubber apron
*Work in a well-ventilated area
*Do not allow tools to touch more than one battery terminal at a time
*ALWAYS disconnect the negative (ground) cable first when replacing batteries to
prevent sparks.
*ALWAYS connect the negative cable last when installing batteries.
CAUTION!
Your voltage regulated lead acid (VRLA) battery will deliver superior
performance and life ONLY IF ITIS RECHARGED PROPERLY! Under
or overcharging will shorten battery life and limit performance. Be
sure to FOLLOW PROPER CHARGING INSTRUCTIONS! DO NOT
ATTEMPTTO OPENTHIS BATTERY! If a VRLAbattery is opened, it
loses its pressure and the plates become oxygen contaminated. THE
WARRANTY WILLBE VOIDED IF THE BATTERYIS OPENED.
If your machine shipped with an onboard battery charger do the following:
1 Turn the Key Switch (A) OFF.
2 See Figure 9. Open the Control Panel Housing (13) set the Prop Rod (32).
3 Empty the Recovery Tank (15) using the Recovery Tank Drain Hose (30). Tip the
Recovery Tank (15) back for proper ventilation.
4 Unwind the electrical cord for the onboard charger near the front of the machine
and plug it into a properly grounded outlet. Refer to the OEM product manual for
more detailed operating instructions. WhileAC power is applied to the onboard
charger all machine functions are disabled.
5 The Battery Charge Status LED (35) will begin flashing green. This indicates that
the charging cycle has begun.As the charging cycle continues, the flashing of the
LED will become more rapid.
6 When the Battery Charge Status LED (35) is steady on, the charging process
has completed. This may take several hours depending upon the condition of the
batteries before charging.
If your machine shipped without an onboard battery charger do the following:
1 Turn the Key Switch (A) OFF.
2 See Figure 9. Open the Control Panel Housing (13) set the Prop Rod (32).
3 Empty the Recovery Tank (15) using the Recovery Tank Drain Hose (30). Tip the
Recovery Tank (15) back for proper ventilation.
4 Disconnect the batteries from the machine and push the connector from the
charger into the Machine Battery Connector (33). Follow the instructions on the
battery charger. SERVICE NOTE: Make sure you plug the battery charger into the
connector that attaches to the batteries.
IMPORTANT: Make sure you have an appropriate charger for use on Gel cell
batteries. Use only “voltage-regulated” or “voltage-limited” chargers. Standard
constant current or taper current chargers MUST NOT be used. A temperature-
sensing charger is recommended, as manual adjustments are never accurate and
will damage any VRLAbattery.

INSTRUCTIONS FOR USEA- ENGLISH
SQUEEGEE MAINTENANCE
If the squeegee leaves narrow streaks or water, the blades may be dirty or damaged. Remove the squeegee, rinse it under warm water and inspect the blades.
Reverse or replace the blades if they are cut, torn, wavy or worn.
To Reverse or Replace the Rear Squeegee Wiping Blade...
1 See Figure 10. Raise the deck and squeegee assembly off the floor, then unsnap the Rear Squeegee Blade Removal Latch (23).
2 Remove the Tension Strap (AA).
3 Slip the rear blade (AB) off the alignment pins.
4 The squeegee blade has 4 working edges. Turn the blade so a clean, undamaged edge points toward the front of the machine. Replace the blade if all 4
edges are nicked, torn or worn to a large radius.
5 Install the blade, following the steps in reverse order and adjust the squeegee tilt if necessary.
To Reverse or Replace the Front Squeegee Blade...
1 Raise the squeegee off the floor, then rotate the squeegee towards the outside of the machine to access. Disconnect the squeegee hose (AD) from the
squeegee. Squeeze the back of the Squeegee Mount Bracket (AE) to open the bracket and pull the squeegee assembly off the machine.
2 Loosen the four Squeegee Cover Knobs (11). Then lift the Squeegee Cover (AF) off of the Squeegee Casting (AG).
3 Slip the front blade (AH) off the alignment pins.
4 The squeegee blade has 4 working edges. Turn the blade so a clean, undamaged edge points toward the front of the machine. Replace the blade if all 4
edges are nicked, torn or worn to a large radius.
5 Install the blade, following the steps in reverse order and adjust the squeegee tilt if necessary.
SQUEEGEEADJUSTMENT
There is only one squeegee assembly adjustment possible, tilt.
Adjust the squeegee tilt if the squeegee is not wiping the floor dry.
1 Park the machine on a flat, even surface and lower the squeegee. Then drive the machine forward enough to have the squeegee blades fold over to the
rear.
2 Adjust the squeegee tilt using the Rear Caster Wheel (AC) so that the rear squeegee blade touches the floor evenly across its entire width and is bent over
slightly as shown in the squeegee cross section (AI).FIGURE 10
