urethane blade system. The “curved” squeegee has a
urethane rear blade and neoprene front blade.
PREPARING THE MACHINE
Installing the Batteries:
 Turn off all switches and tilt the recovery tank open to
expose the battery compartment.
 Batteries are heavy - use two people to install.
 Refer to the wiring diagram inside the battery
compartment. Align batteries in the compartment as
shown on the diagram.
 Install battery cables as shown on the wiring diagram.
 Tighten bolts and hex nuts with a wrench.
Caution: Do not short across two terminals with a
wrench. Possible personal injury may occur.
 Loose or improper battery connections will cause
battery or machine damage and possible personal
injury.
 Charge the batteries before use!
Battery Charging
 To recharge the batteries plug the charger cord,
located at the rear of the machine, into an electrical
outlet (100/115/230 50/60HZ VAC).
 When the cord is plugged into an outlet the machine
will become disabled.
See Battery Charger section for more details.
Preparing the Solution and Recovery tanks:
 Never use water over 140°F (60°C) degrees.
 Excessively hot water may damage components such
as the tanks.
 Make sure the drain plug of the recovery tank is
closed tightly and in its holding clip.
 Put 1 to 2 gallons of clean water into the solution tank
first to help dilute the chemicals and prevent excess
sudsing. Dilute the cleaning chemicals according to
the manufacturer’s instructions.
 Fill the tank by pouring the water and cleaning
chemicals through the mesh filter that covers the
opening at the front of the solution tank.
 Always use a defoamer to protect the vac motor.
 Consult your local distributor for complete chemical
advice.
Install a pad driver and pad:
 There is a wide range of pads or brushes available for
the many cleaning applications of this machine.
Consult your local NSS distributor for application
recommendations.
 Turn the pad driver upside down on the floor and
remove the pad holding cup.
 Remove the center cutout of the pad. Place the pad
on the face of the pad driver.
 The pad must be centered on the driver to prevent
wobbling or bouncing.
 Install and secure the pad holding cup to the pad
driver. Turn the pad driver over so that the pad faces
the floor.
 Raise the brush motor into the transport position.
 Align the slots of the pad driver with the lugs of the
drive casting.
 Turn the pad driver until it stops and stays in place.
Install a Brush:
 Raise the brush motor into the transport position.
 Align the slots of the brush with the lugs on the drive
casting.
 Turn the brush until it stops and stays in place.
Install the squeegee assembly:
 Place the squeegee lift handle in the storage (up)
position.
 The squeegee assembly mounts to a metal bracket at
the rear center of the machine, using two (2)
mounting knobs. Loosen the mounting knobs and
slide the squeegee assembly onto the mounting plate.
 The squeegee assembly has two (2) small wheels to
prevent “rollover” while in reverse. The roller wheels
must face the operator. Hand tighten the mounting
knobs. Do not use pliers to tighten knobs, as this will
defeat the “breakaway” design.
 Do not add any weights or other pressure to the squeegee mechanism. This will not improve the performance and will shorten the life of the blades.
 It is recommended that, with new blades, the rear
wheels be adjusted to their lowest position. Loosen
the two screws on the bracket rotate the bracket
downward as far as it will go, then tighten the screws.
Perform this adjustment on both wheels/brackets.
 When the squeegee becomes worn, and the wiping
edge no longer contacts the floor properly, further use
may be possible by adjusting the rear wheels upward
enough to restore proper engagement of the blades
wiping edge with the floor. Be sure to adjust the
wheels back down fully when a new blade is installed.
Operating the Machine
The Wrangler 2016 has the brush motor offset to the
right side of the machine. This offset allows you to
clean the edge of a floor or an obstructed area (walls or
shelving) with the right side of the machine.
Normal Cleaning
 Sweep and dust mop the floor to remove dirt and
debris before scrubbing. Accumulations of dirt or
debris on the floor will reduce cleaning performance.
 You may also need to preclean some types of spills
or stains before scrubbing.
 Plan your work so that you make long, straight paths
with the fewest amount of turns possible, overlapping
each cleaning path about 2 in. (5 cm.) to prevent
streaking and dirty areas.
 Move machine to area to be cleaned.
 Place “Wet Floor” warning signs in area.
 Turn on master switch.
 Turn on vacuum motor switch.
 Lower the brush motor and squeegee assembly into
the operating position on the floor.
 AB Models - The brush motor is turned on and off
with the brush switch on the control panel.
 DB Models - The brush motor will automatically turn
on when moving either forward or backwards.
 Lift solution valve handle to start liquid flow to floor.
Adjust amount of flow as needed. Close the solution
valve completely 10 ft (3 m) before you turn at the
end of your cleaning path. This will reduce the
amount of liquid on the floor when you make your
turn.
 Reopen the solution valve when starting the next
pass. Repeat this procedure for each pass.
 NOTE: Solution will not flow until brush turns on.
 Watch the level of liquid in the recovery tank and
listen for the float shut-off to change the sound of the
vac motor. When the vacuum airflow stops, you must
turn off the vacuum motor and empty the recovery
tank.
 Take the machine to an approved disposal drain and
turn off all switches.
 Pull the flexible rubber drain hose out from behind the
brush motor. Raise the end of the hose above the
level of the recovery tank, loosen and remove the
hose drain plug. Carefully direct the drain hose into
the drain.
 When the recovery tank is empty, replace and tighten
the drain plug. Place the drain hose back behind the
brush motor. Do not obstruct the lift mechanism or
brush motor.
Special Cleaning
This machine may be used to perform special cleaning
jobs other than “normal” scrubbing.
Double scrubbing
 This procedure provides deeper cleaning on heavily
soiled floors. One or more cleaning passes are made
before picking up the chemicals with the squeegee.
This allows dwell time. Best results are achieved by
placing the brush motor in the heavy scrub position.
Caution: The floor surface becomes extremely slippery
in this operation. This machine should be operated only
in slow to medium speed and great care should be
taken when walking on this wet surface.
Stripping
 This procedure is used to remove moderate build-up
of floor finish from the floor. The most aggressive
pads or brushes are used in this procedure.
 The stripper solution is applied to the floor with a mop
and then double scrubbed as described above.
Stripping solution should not be put into the solution
tank. Clean water from the solution tank is applied to
the floor to keep the chemicals and finish in a “liquid”
condition. The floor surface becomes extremely
slippery in this operation. This machine should be
operated only in slow to medium speed and great
care should be taken when walking on this wet
surface.
MACHINE MAINTENANCE
Routine maintenance is critical to ensure proper
machine operation and cleaning performance. Perform
all maintenance procedures as follows.
Always turn OFF all machine switches before
performing any maintenance.
Adjusting the squeegee assembly:
 Turn the vacuum motor ON and open the water valve
slightly.
 Squeegee blades should lie over slightly (like a
window squeegee) when the machine is moving.
 If adjustment is required adjust the blade angle by
turning the wing nut on the squeegee mount.
Daily Maintenance
Battery Charging
 The master power switch and all other switches
must be turned OFF.
 You must recharge the batteries when indicated by the
battery meter, and after every use. Read the battery

 Determine which Battery Charger you have - then see
the Operating Instructions for that Charger.
 NSS-Pro Charging: LED’s & metal housing
 SPE – digital display and plastic housing.
Battery Electrolyte (liquid) Level (Flooded only)
Inspect the electrolyte level of at least one cell in each
battery before daily charging. The liquid must be visible
above the internal plates. Do not charge the batteries if
the liquid is below the plates.
 NEVER let the electrolyte level fall below the tops of
the plates. This will damage the batteries
immediately, and void the warrantee.
 Add only distilled water to the cell of a battery to adjust
the liquid level. Do not use well or tap water. Before
charging, add only enough water to cover the top of
the internal plates. After charging, add only enough
water to bring the level to the bottom of the fill tube.
 Do not overfill the battery liquid, this will cause
electrolyte (acid) spill. Spilled electrolyte (acid) can
cause machine damage and personal injury. Clean
and dispose of spills immediately.
 Every cell of every battery must be checked and
replenished (if needed) once per week
 See the battery-warning sheet (page 2) for more
details.

 Two (2) 12 volt, 145 Amp Hour Batteries - SPE.
Solution and Recovery Tanks
 The recovery tank is emptied through a large rubber
hose at the front of the machine. Remove the plug
and drain the liquids according to your local and
federal regulations.
 Every time you empty the recovery tank, we
recommend that you add at least 4 to 6 ounces of
defoamer chemical into the recovery tank before
resuming work. Vacuum the defoamer into the empty
recovery tank through the squeegee vac hose.
 At the end of the day empty all liquids from both
solution and recovery tanks. Rinse both tanks with
clean water to prevent chemical residue build-up,
allow to air - dry to prevent odors.
 Remove any residue from screen and float ball to
ensure proper operation. Replace float assembly in
recovery tank.
 Check clear lid for airtight seal.
 Check the drain hose for damage.
 Inspect and clean the vac filter located under the top
metal plate. Every 50 hours.

of according to local and federal regulations.
 Check solution flow to pad driver and / or brush.
Remove, inspect and clean solution filter assembly.
 Flush solution tank and hoses with a mixture of
8oz/250 ml white vinegar to 1 gal/4 l water.
 Repair or replace any worn or damaged components
as needed.
 Inspect and clean float screen and small vac filter
above float.
****CAUTION****
Inspect and replenish battery water in every cell in
every battery weekly. Failure to maintain proper
electrolyte level in every cell of every battery will cause
premature battery failure, and void the warrantee.
Monthly Maintenance (100 Hours)
 Equalize your batteries (Flooded only). To equalize
the batteries, after they have been fully charged,
unplug the charger (from the wall outlet), and plug it
back in. The charger will skip thru the first few
phases of the charge cycle, and run thru the finish
phase. This will balance out all the cells in the
batteries, and provide maximum battery life. THIS
STEP IS ESPECIALLY IMPORTANT IF YOU
PRACTICE OPPORTUNITY CHARGING.
 Verify all daily and weekly maintenance has been
performed.
 Lube the caster and swivel bearings. Spray with
Silicone Lubricant.
 Inspect all mechanical linkages, pivot points and ball
joints for freedom of movement. Use a penetrating
spray lubricant that is water resistant. Do not use
WD-40 lubricant.
 Inspect all fasteners (bolts, screws, nuts) at
mechanical linkages, pivot points and ball joints for
tightness. Tighten as needed.
 Clean polyethylene body components to remove
chemical and liquid residue and maintain a “like new”
appearance.
Mandatory Periodic Maintenance
It is mandatory that the following maintenance procedure
be performed at the described interval. Failure to perform
this procedure may result in poor machine performance,
component damage and failure. This procedure should be
performed by an NSS authorized distributor or service
center. Repairs not performed by an unauthorized
company will void the machine warranty. If you require
assistance finding an authorized service center, contact
NSS Enterprises.
After every 450-500 hours of operation you must inspect
vac motor carbon brushes for wear. Replace the vacuum
motor carbon brushes when they are 7/16 in. (11 mm) in
length.
After every 650-700 hours of operation you must inspect
the drive motor (transaxle) carbon brushes for wear.

Operating the Battery Charger
CAUTION: DIFFERENT BATTERY TYPES HAVE
DIFFERENT CHARGING REQUIREMENTS.
FAILURE TO PROPERLY IDENTIFY YOUR
BATTERY TYPE, AND SET THE CHARGER
.ACCORDINGLY, WILL RESULT IN BATTERY
DAMAGE, AND VOID THE WARRANTEE.
The battery charger is fully automatic. Simply plug the
charger into a suitable wall outlet, and the charger will
charge the batteries. The green 100% LED will be
continuously illuminated when the charge cycle is
complete.
A bubbling, or boiling sound coming from the
batteries during the last few hours of the charge is
normal. The batteries may be warm, but not too hot to
touch.
The charger will maintain the proper battery voltage
as long as it is plugged in (maintenance mode).
Equalizing the batteries (Flooded only)
The batteries should be equalized once every 30 days
for maximum battery runtime and life.
To equalize the batteries:
 Plug in the charger, and fully charge the batteries
(until the green 100% LED is on continuously).
 Unplug the charger from the wall outlet, then plug
it back in.
 The charger will run for 2hrs, holding the
batteries at a constant voltage, and equalizing
each cell.
Battery Do’s and Don’ts:
a. You do not have to fully discharge the batteries
before charging. They do not have a “memory”.
b. Plug the charger in anytime the machine is not in
use.
c. NEVER let the electrolyte level fall below the tops
of the plates (flooded cell batteries). This will
damage your batteries almost immediately, and
void the battery warrantee. They can tell if this
happened.
d. NEVER refill the batteries with well or tap water
(flooded cell batteries).
e. NEVER overfill the batteries (flooded cell batteries).
f. NEVER let the batteries sit discharged overnight
(or between shifts).
g. ALWAYS check the electrolyte level about every 3
or 4 charge/discharge cycles BEFORE
CHARGING.
h. ALWAYS refill the batteries with distilled water (if
needed) AFTER CHARGING.
i. ALWAYS fully recharge the batteries after use (until
the green LED comes on).
j. ALWAYS equalize the batteries (Flooded only)
every 30 days.
k. NEVER OVER DISCHARGE!
l. NEVER charge GEL batteries with the charger set
to FLOODED/AGM.
m. NEVER charge FLOODED/AGM batteries with the
charger set to GEL. EXCEPTION-TROJAN
AGM’S TO BE CHARGED WITH GEL SETTING.
Opportunity Charging
Opportunity charging is charging the batteries when
an opportunity presents itself, such as during breaks,
and is done in addition to a full charge cycle.
Opportunity charging is recommended, as this extra
charging time will help raise the operating voltage of
the batteries, and will help ensure maximum runtime
and cycle life.
NOTE: If battery charger is unplugged before the
charging cycle is completed, it may take up to five
minutes before the machine to be able to be turned on

GENERAL INFORMATION AND WARNINGS
 NSS machines are delivered with the SPE charger
set to Curve #0 for Crown batteries.
 Electronic automatic battery charger with
microprocessor suitable for any battery type.
 Fully automatic charging cycle with electronic
setting; protected against overload, short-circuit at
clamps and reversed polarity.
 Before starting to charge, make sure the voltage of
the equipment suits the voltage of the battery, that
the charging current suits the capacity of the
battery and that the selected charging curve (for
lead-acid batteries or airtight gel batteries) is
correct for the type of battery to be charged. In
addition, make sure the rated input voltage of the
charger suits the available supply voltage and the
system is equipped with grounding.
 Pay attention to any remarks of the battery
manufacturer.
CONTROLS (see figure below)
1. Three-digit display + symbol (1), to view A = the
charging current, U = the battery voltage, h = the

2. Button for the Selection of the display mode
(2):A, U, h, C, E. After about 10 seconds the
display returns to the visualization of the charging
current.
3. Red control indicator (3): when it is on, the
charging cycle has started.
4. Yellow control indicator (4): when it is on, the final
phase of the charging cycle has started.
5. Green control indicator (5): when it is on, the
charging cycle has finished.
OPERATION INSTRUCTIONS
 Plug the cord into a socket.
 Now, the battery charger’s display will show a
sequence of details on the charger’s internal
programming: after the name “SPE”, it will show
the software release installed in the equipment,
then, in sequence, the following parameters:
battery voltage, charging current, charging curve
number and, finally, the words “GEL” or “Acd”
depending on the set up charging curve being
suitable for airtight gel batteries or lead-acid
batteries. Now, a test is run on the battery voltage
to decide if the charging process should be started
or not. If the battery is not connected to the battery
charger, the display will show the word “bat”. The
word will stay on, even if the test is failed (for
instance, reversed polarities or incorrect battery
connection). If the test is passed, the display will
show the battery voltage for approximately 5
seconds and the battery will begin to be charged.
The charging cycle progress will be shown by red
(3), yellow (4) and green (5) LED indicators. At the
end of the charge, when the green indicator (5) is
on, unplug the cord from the socket and operate
the machine.
