then apply pressure with your foot on the Go Pedal (24). An audible alert from the speaker will sound in reverse.
NOTE: Stepping off of the Operator’s Presence Pedal (25) for more than 2 seconds will cause the Forward or Reverse Drive Switch Indicator to turn
off. The operator will need to select forward or reverse again before the machine can be driven.
7 Adjust machine speed by rotating the Speed Adjustment Knob (P) clockwise to go faster or counterclockwise to go slower.
NOTE: While the machine is operating in autonomous mode the machine’s speed is set by the computer and not adjustable by using the speed
adjustment knob.
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.
Do not operate autonomously when ambient RF signal falls at or near the frequency range of 340 MHz to 460 MHz.
Operating Modes
The Nilfi sk Liberty SC50 has three operating modes:
• Manual Operating Mode: Provides normal functioning of the machine, without autonomy. In this mode the machine is driven and controlled by an operator,
and operates in a conventional manner. The machine must be driven in the manual mode while creating plans the machine will follow during Autonomous
Operation. This includes driving to and from the autonomous scrubbing plans (locations). Full details of the Manual Operating Mode are contained in the
OPERATING THE MACHINE MANUAL MODE section of this manual.
• Autonomous Mode: The Autonomous Operating Mode is used to perform scrubbing operations automatically, without active Operator involvement. This is
done by training the machine to follow a specifi c plan or perimeter of an area.
- Plans may also include specifi c actions the machine will make while performing the scrubbing activity. Such actions might include knowing when to raise
or lower the scrub deck, how much solution to dispense. When played back, the plan tells the machine exactly what to do; what path it should follow, and
what scrubbing actions it should take along the way.
- To operate autonomously, the machine needs to always know exactly where it is in relation to the recorded plan, and the operating environment. This
mapping process operates constantly, in every operating mode, whenever the machine is turned on.
• Training Mode: Used to create plans (either CopyCat™ or Fill-In) the machine will follow when scrubbing autonomously. Before the machine can operate
autonomously, it must be trained to follow a specifi c plan(s) while scrubbing. During training, both the plan and required actions are recorded and saved.
STARTING THE MACHINE
1 Follow the instructions in “Preparing the Machine for Use” section of this manual and verify the following;
• Exterior of machine is free of damage. Report any damage to your supervisor.
• Proper brush/pad is correctly installed.
• Squeegee is installed.
• Camera and laser lenses are clean, see CLEAN SENSOR LENSES section.
• Batteries are fully charged.
• Solution tank is full.
• Recovery tank is empty.
• Location tag is properly installed to a wall
• Home Position is set (required for autonomous operation).
• Ensure that area to be scrubbed is clear of obstacles that are not fi xed, such as hoses, buckets or pails, boxes, electrical cords, carts, pallets, etc.

WHILE TRAINING/RECORDING IN COPYCAT OR FILL-IN MODES...
Operator is interrupted
1 If operator is interrupted during the recording process, release foot from Go Pedal to stop machine and step off the machine to stop all
functions. If operator steps off the machine at any time during the record process the machine will stop.
2 Remove the magnetic SmartKey and attend to other issues.
3 After returning step back onto the machine, replace the SmartKey and press the Record Switch (U) to resume training.
Training needs to be stopped
1 If training needs to be stopped during the recording process (to re-fi ll solution tank, empty recovery tank etc.) release foot from Go Pedal to
stop machine movement and press the Play/Pause Switch (T) to stop recording.
2 The machine will not remember where it left off training and plan must be re-recorded. After emptying recovery tank, refi lling solution etc.,
return to starting point and re-train the plan.
Important to Know About Training a Plan
• Be mindful of where you start a plan so it’s not in a busy or congested area, but also in a logical place to start cleaning. Start point should
be in a location that’s easy to remember and get to in the future since machine will need to start there each time to playback.
• Be mindful of where you will end the plan (only for CopyCat) so that machine is not blocking a doorway or otherwise in the way when it
comes to a stop at the end of the plan.
• Train plan with the left side of the machine facing into the room.
• Two plans cannot have the same starting point. If two starting points are close to each other the machine will playback the plan which has
the starting point nearest to the machine. Any two starting points should be a minimum of 8 ft. (2.4m) apart.
• For CopyCat plans the start and end points do not need to be the same location.
Results of Training a Plan Include
• Saved plan guides machine movements during autonomous operation.
• Machine will follow exact plan(s) recorded, avoiding known obstacles identifi ed on plan.
• Machine will drive around new obstacles detected but not recorded.
• Machine will signal the remote to notify Operator if there are problems or machine cannot move around newly detected obstacles.
• Machine will signal the remote when the machine has fi nished cleaning and reached the end of the plan.
DELETE A PLAN
1 Cancel Current Recording:
a. During training press Stop Switch (T) at any time to bring up a menu which allows the operator to cancel/delete the current plan being
trained.
2 Delete Existing Plan:
a. Drive machine to the start area of the plan.
b. Machine will recognize the plan by an audible alert (2 beeps), lighting the appropriate LED either CopyCat or Fill-In that corresponds to
the plan.
c. Press Autonomous Switch (S) to enter Autonomous menu choose “Delete this plan”.

OPERATING THE MACHINE MANUAL MODE
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.
1 Follow the instructions in “Starting the Machine” section and drive the machine to the starting point for cleaning.
2 Press and hold the Solution Switch (J) to pre-wet the brush or pad, solution will be dispensed at the HIGH rate while the switch is held. NOTE: This will
help prevent scarring of the fl oor surface when starting to scrub with dry brushes. This can only be done prior to pressing the One-Touch Scrub Switch (M).
Additionally when the machine starts scrubbing the solution will fl ow at the High rate for 2 seconds to fl ood the fl oor.
3 Press the One-Touch Scrub ON Switch (M) once for Regular Scrub. Press the Extra Pressure Switch (N) once for Heavy Scrub. The solution fl ow has
settings that coincide with the scrub pressure, it will increase and decrease along with the scrub pressure.
NOTE: The solution fl ow rate can also be increased or decreased independently of the scrub pressure by pressing the Solution Flow Adjustment Switch (J),
observe the Solution Flow Rate Bar Graph (X10) (see Control Panel). Any subsequent scrub pressure adjustments will reset the solution fl ow rate to default.
4 When the One-Touch Scrub ON Switch (M) is selected, the brushes and squeegee are automatically lowered to the fl oor. The scrub, solution, vacuum and
detergent systems are all automatically enabled and will start when the Go Pedal (24) is activated. Any individual system can be adjusted or turned OFF or
ON by simply pressing its switch at any time during scrubbing.
Scrub Pressure: Each press of the Extra Brush Pressure Switch (N) will change between REGULAR pressure and HEAVY pressure (shown on the display
(X12)). The scrub system can only be turned OFF by pressing the One-Touch Scrub Switch (M).
Solution: The solution fl ow rate can be changed independently of the scrub pressure by pressing the Solution Switch (J). Each press of the switch will cycle
between LOW, MEDIUM, HIGH, OFF and back to LOW. The setting is shown on the display (X10).
Vacuum: The vacuum level can be changed independently. The default setting is REGULAR mode. Each press of the Vacuum Switch (L) will cycle
between QUIET, OFF and REGULAR. The setting is shown on the display (X5).
NOTE: To pick up solution without scrubbing, press the Vacuum Switch (L) while in transport mode. This will cause the squeegee to lower and the vac
motor to turn ON at the REGULAR level.
Detergent: See “Detergent System Preparation and Use (EcoFlex)” for more detailed information regarding the adjustment and use of the detergent system.
5a Daily Scrub: Begin scrubbing by driving the machine forward in a straight line at a normal walking speed and overlap each plan by 2-3 inches (50-75 mm).
Adjust the machine speed and scrub parameters when necessary according to the condition of the fl oor.
5b Floor Finish Removal (REV model only): Ensure there is a red pad attached directly to the fi xed pad driver and that the maroon SPP pad is not attached
to the fi xed pad driver. Adjust the scrub parameters as follows: Adjust the machine speed potentiometer to a slow scrub speed approximated by that shown
in Figure 6 (P). Adjust the solution fl ow rate to low, the scrub pressure to high and turn detergent off. The vacuum power setting can be set to either quiet or
regular mode.
6 Press the Burst of Power Switch (O) to temporarily (1 minute) engage the high detergent strength, extra scrub pressure, full vacuum power and increase the
solution fl ow rate to the next available level. The Burst of Power Indicator (X22) will display along with a 60 second countdown timer, after which all scrub
parameters will return to their previous state.
7 When scrubbing, check behind the machine occasionally to see that all of the used solution 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 raised position. Lift up the squeegee assembly and rotate the double scrub
bracket (AA) down, to hold the squeegee off the fl oor. 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.
9 The recovery tank has a Tank Full Switch (21) that causes ALL systems to turn OFF except the drive system when the recovery tank is full. When this switch
is activated, the recovery tank must be emptied. The machine will not pick up water or scrub with the switch activated.
NOTE: Scrub, solution and detergent indicators vanish and the Recovery Tank Full Indicator (X16) appears on the Display Panel when the switch is
activated.
10 When the operator wants to stop scrubbing:
Press the One-Touch Scrub Switch (M) once. This will automatically stop the scrub brushes and solution fl ow 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 an additional 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 “DISPOSAL SITE” and empty the recovery tank. To empty, pull the Recovery Tank Drain Hose (37) 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 fl ow of waste water). The
drain hose can be squeezed to regulate the fl ow. Unlatch (36) and lift open the Recovery Tank Cover (20) to inspect and empty the Debris Catch Tray (23) in
the recovery tank. Refi ll the solution tank and continue scrubbing.
NOTE: Make sure the Recovery Tank Cover (20) and the Recovery Tank Drain Hose (37) cap are properly seated or the machine will not pick-up water correctly.
When the batteries require recharging the Battery Low Voltage Indicator (X13) will come on, the scrub brushes and solution fl ow will stop and the scrub deck will
raise up. The squeegee will raise up after a brief delay and the vacuum will stop after an additional delay. Transport the machine to a service area and recharge
the batteries according to the instructions in the Battery section of this manual.

AFTER USE
1 When fi nished scrubbing, press the One-Touch Scrub Switch (M), this will automatically raise, retract and stop all the machine systems
(brush, squeegee, vacuum, solution and detergent). Drive the machine to a service area for daily maintenance and review of other needed
service upkeep.
2 To empty the solution tank;
• Solution tank only needs to be emptied if detergent was mixed in the tank and machine will not be used for a while.
• Drive the machine over a designated “DISPOSAL SITE” and open the Solution Drain Valve (8).
• The tank can also be drained by closing the Solution Shutoff Valve (34) and removing the cap from the Solution Filter (33), then open the
Solution Shutoff Valve to drain the solution out through the fi lter.
• Rinse the tank with clean water if detergent was used in the tank.
3 To empty the recovery tank;
• Pull the Recovery Tank Drain Hose (37) from its storage area.
• Direct the hose to a designated “DISPOSAL SITE” and unscrew the cap (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 can be squeezed to regulate the fl ow.
• Unlatch (36) and lift open the Recovery Tank Cover (20) set the prop rod (39).
• Empty and rinse the Debris Catch Tray (23) in the recovery tank.
• Thoroughly rinse the recovery tank with clean water.
• Inspect the squeegee and drain hoses; replace if kinked or damaged.
4 Remove the brush or pad holder. Rinse it in warm water and hang up to dry.
5 Remove the squeegee, rinse it with warm water and hang it up to dry. Inspect the squeegee blades for wear or tears.
6 Check the maintenance schedule below and perform any required maintenance before storage.
7 Store the machine indoors in a clean dry place. Keep from freezing. Leave the tanks open to help prevent odors.
8 Turn the machine off by pressing the Power Switch (B) and then remove the magnetic SmartKey.
9 Batteries are one of the most expensive replacement items on this machine. To protect your investment and to get as many cycles from the
batteries as possible, remember the following:
When installing batteries make certain the machine and charger are programed for the correct battery type.
Batteries will last longer if they are kept fully charged.
Batteries will prematurely fail if stored in a discharged state.
Battery chargers will not over or undercharge the batteries.
Every day after use, the battery charger must be plugged in and the charger must be allowed to run through a full charging sequence to
fully charge the batteries. This may take 8-12 hours depending on the battery status.
Always have the charger plugged into an AC outlet if the machine will not be used for a longer period of time to keep the battery(s)
charged.

Use grease type Lubriplate® 730-2 or equivalent
• Steering Chain
• Drive Wheel Chain
• Drive Chain Idler Sprocket (grease fi tting)
FIGURE 4-1
ELECTROMAGNETIC BRAKE
See Figure 4-2. The drive wheel motor has a built in electromagnetic brake that is engaged whenever the machine Power Switch (B) is OFF or
the Go Pedal (24) is not being pressed, machine in neutral. This brake can be manually overridden if necessary by reaching up around the back
of the front drive wheel and rotating the Brake Arm (AC) as shown. This should only be done in the event the machine needs to be pushed or
pulled. Remember to re-engage the brake arm after the machine is moved.
CAUTION!
Disconnect the batteries before
reaching into this area and rotating the
brake arm. Severe injury could occur if
steering components suddenly move.
IMPORTANT: The steering is controlled
electronically rather than by mechanical
linkage. This means that whenever the
power is off the machine cannot be steered
using the steering wheel.

CHARGING GEL/AGM (VRLA) BATTERIES
Charge the batteries each time the machine is used or when the Battery Indicator (X3) is reading less than full.
X3
20
WARNING!
Charge batteries in a well-ventilated area. If battery acid makes contact with your skin, fl ush the affected area with water for 5
minutes and seek medical attention.
Do not smoke while servicing the batteries.
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 fi rst when replacing batteries to prevent sparks.
* ALWAYS connect the negative cable last when installing batteries.
CAUTION!
Your valve regulated lead acid (VRLA) battery will deliver superior performance and life ONLY IF IT IS RECHARGED PROPERLY!
Under or overcharging will shorten battery life and limit performance. Be sure to FOLLOW PROPER CHARGING INSTRUCTIONS!
DO NOT ATTEMPT TO OPEN THIS BATTERY! If a VRLA battery is opened, it loses its pressure and the plates become oxygen
contaminated. THE WARRANTY WILL BE VOIDED IF THE BATTERY IS OPENED.
CAUTION!
When the Control Panel Housing (20) is opened it creates a pinch point between the LED lens and the solution tank. Do not route
the power cord through this area or the cord will be pinched and may be damaged.

FIGURE 4-4
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 VRLA battery.
FIGURE 4-3
5 The Battery Charge Status Indicator (X3) will begin showing the
batteries’ state of charge. This indicates that the charging cycle has
begun. As the charging cycle continues, the battery charge level will
fi ll in. Each of the fi ve bars within the icon will fl ash and then become
solid until all of the fi ve bars are lit solid. The Display (X) will also
show battery voltage and percent of charge (X47).
6 The LED status bar (4) will also display the state of charge, using
advancing colors from red to green see Figure 4-5.
7 When the Battery Charge Status Indicator (X3) is completely fi lled
and status bar is solid green, the machine senses fully charged
batteries, however the charging process may not be complete. Rely
on the status lights on the Charger (31) (and its OEM manual) to
verify when the batteries are completely charged. This may take
several hours depending upon the condition of the batteries before
charging.
8 After charging is complete unplug the charger and wind up the Cord
(40). Wait at least 10 seconds before turning on the machine after
unplugging the charger.
