and prevent splashing on the outside of the machine.
PREPARING THE MACHINE
Installing the Batteries:
 Turn off all switches (except the EMERGENCY
STOP) 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.
 Loose or improper battery connections will cause
battery or machine damage and possible personal
injury.
Battery Charging
 To recharge the batteries, plug the charger cord,
located at the rear of the machine, into an electrical
outlet (100/115/230 50/60 HZ VAC).
CAUTION: Make sure the battery type LED on the
charger matches the type of battery installed in
your machine! EXCEPTION-CROWN AND TROJAN
AGM’S TO BE CHARGED WITH GEL SETTING.
 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.
 Put 1 to 2 gallons [3.8L to 7.6L] of clean water into the
solution tank first to help dilute the chemicals and
prevent excess suds. Dilute the cleaning chemicals
according to the manufacturer’s instructions. See
Sidekick instructions if equipped with on-board
dilution control.
 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, or you may
use the hose holder cutout.
 Make sure the drain plug of the recovery tank is
closed tightly and in its holding clip.
 Always use a defoamer to protect the vacuum 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. Consult your NSS
authorized distributor for recommendations.
 Turn the pad drivers upside down on the floor and
remove the pad holding cup.
 Remove the center cutout of the pad, 14" (35.5 cm.)
Wrangler 2730, 17” (43 cm) pad Wrangler 3330.
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 motors into the transport position.
 Align the lugs of the pad driver with the slots of the
drive casting.
 Turn the lugs of the pad driver toward the latch; close
the latch around the lugs to lock them onto the drive
casting.
Install a Brush:
 Raise the brush motors into the transport position.
 Align the lugs of the brush with the slots on the drive
casting.
 Turn the lugs of the brush toward the latch; close the
latch around the lugs to lock them onto the drive
casting.

Install the Squeegee Assembly:
 Place the squeegee lift arm in the storage (up)
position.
 The squeegee assembly mounts to a metal bracket at
the bottom 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 “break-away” 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.
Install the Side Skirts:
 Position the skirts at the front left and right sides of
the machine.
 Remove the skirt retaining pins from the mounting
bracket.
 Align the side skirt holes with mounting bracket holes,
insert and secure with retaining pins. Close side
skirts around machine and secure with skirt retaining
latch.
Prepare the Sidekick Chemical dispenser (if
equipped)
***CAUTION: Purging the Sidekick lines may
dispense a small amount of the chemical directly
onto the floor. If using wax stripper or harsh
chemicals, be sure to purge the lines in an area
that cannot be damaged by the chemical in use.
 Place a container filled with the desired cleaning
chemical into the bottle holder located at the front of
the machine.
o The bottle holder accepts F-style rectangular
containers, and some smaller round containers.
o Empty F-style containers are available from NSS,
order part #9590171.
 Ensure all hose fittings are tight, then insert the
suction tube into the chemical bottle, and tighten the
cap.
 Turn on the Scrubber then press the “ON” button on
the Sidekick. The ON indicator will illuminate.
 Press and hold the PURGE button on the Sidekick
until you see the supply line to the pump filled with the
chemical.
 Select the desired dilution ratio as recommended by
the chemical manufacturer.
 The Sidekick Chemical dispenser is ready for use.
Operating the Machine
Do not operate the machine with the battery meter
needle in the red zone.
The Wrangler 2730 has the brush motors offset to the
right side of the machine. This offset allows you to
clean the edge of the floor or obstructed areas (walls or
shelving) with the right side of the machine. The 3330
have the brush motors centered but the offset feature is
part of the skirt design.
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 pre-clean 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 warning signs “Wet Floor” in area.
 Turn on master switch.
 Turn on vacuum motor switch.
 Lower the brush motors and squeegee assembly into
the operating position on the floor. Brush motors will
automatically turn on when lowered and moving in
forward or reverse.
 Lift solution valve handle to start liquid flow to floor.
Adjust amount of flow as needed. Close the solution
valve completely 10 ft. (3m.) before turning at the end
of each cleaning path. This reduces the amount of
liquid on the floor when you make the turn.
 Reopen the solution valve when you have started
your next cleaning path. Repeat this procedure on
each path.
 NOTE: Solution will not flow until brushes turn on.
 Watch the level of liquid in the recovery tank and
listen for the float shut-off to change of the sound of
the vacuum 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.
 Raise the rubber flap at the front of the machine and
pull out the flexible rubber drain hose. Raise the end
of the hose above the level of the recovery tank,
loosen and remove the hose drain plug. Carefully
lower and direct the drain hose into the drain.
 When the recovery tank is empty, replace and tighten
the drain plug. Place the drain hose back into the
machine and secure the plug end in the clamp. Do
not obstruct the lift mechanism or brush motors.
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 motors 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 grit brushes are used in this procedure.
 The stripper solution is applied to the floor with a mop
and then double scrubbed as 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.
 If equipped, the scrubber may be used to apply the
wax stripper using the Sidekick Chemical dispenser.
Set the dilution ratio to the rate recommended by the
chemical manufacturer. If the wax stripper you are
using requires dilutions stronger than 20:1, then you
will need to apply the stripper with a mop.
 After applying the stripper, thoroughly purge the
Sidekick Chemical dispenser lines with clean water to
remove all traces of wax stripper. Purge the lines
while the scrub brushes are positioned over a floor
drain. Purging the Sidekick’s lines will dispense
chemical thru the scrub pads and onto the floor.
Sidekick Chemical Dispenser Operation
***CAUTION: Purging the Sidekick lines may
dispense a small amount of the chemical directly
onto the floor. If using wax stripper or harsh
chemicals, be sure to purge the lines in an area
that cannot be damaged by the chemical in use,
such as over a floor drain.
See Preparing the Machine for instructions on how to
connect the chemical bottle, and purge the lines.
After proper connection of the chemical supply line and
purging, the Sidekick Chemical Dispenser provides fully
automatic chemical dilution during scrubbing
operations. The Sidekick measures the amount of
water flowing out of the solution tank, and pumps the
correct amount of chemical into the water line to provide
the ratio of water to chemical according to the dilution
ratio selected on the control panel.
The pump will not operate unless water is flowing from
the solution tank (except when the purge button is
pressed). This means the Solution Control valve must
be on, and the brushes must be spinning.
Basic Operation
 Turn on the Scrubber.
 Turn on the Sidekick Chemical Dispenser.
 Select the desired dilution ratio by pressing the Select
Dilution button until the light next to the desired ratio
is illuminated.
 The scrubber can be turned off, and when the
scrubber is turned back on, the Sidekick will recall the
last dilution setting.
 During use, the Purge button may be pressed to
provide and extra dose of chemical for heavily soiled
areas (always follow chemical manufacturer’s usage
directions).
To Change Chemicals
 Loosen the cap on the chemical bottle, and remove
the suction line from the chemical bottle.
 Dispose or store any remaining chemical according to
local and federal regulations.
 Place the suction line into a container of clean water.
 With the machine over a floor drain, press and hold
the purge button until the clean water is drawn thru
the pump and dispensed at the brushes.
 Remove the suction line from the container of clean
water. Replace the container of clean water with a
container of the desired chemical, and install the
suction line.
 Press and hold the Purge button until chemical is
seen being drawn up to the pump, and pumping down
the tube from the pump to the tee fitting below the
machine.
 After each use, always flush the Sidekick lines
with clean water to prevent dried chemical from
accumulating in the lines.

Daily Maintenance
Battery Charging
 The master power switch and all other switches
(except the EMERGENCY STOP) must be turned
OFF.
 You must recharge the batteries when indicated by
the battery meter, and after every use. Read the
battery meter while the machine is in use.
*350 AH batteries normally require 14 ½ -16 1/2 hours
to fully charge.
 NEVER let the batteries sit overnight after the
machine has been run for more than 1 hour since last
recharge.
 See Battery Charger section.
Battery Electrolyte (Liquid) Level (Flooded only)
Inspect the electrolyte level of at least one cell in each
battery before charging. The liquid must be visible
above the internal plates. Do not charge the batteries if
the liquid is below the plates.
 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

Battery Replacement Notes
 Entire Pack.
o It is always recommended to replace all batteries in
the pack at the same time.
 One or more batteries out of the pack. This is not
recommended. Replacing just one or two batteries
out of the pack can lead to the following:
 Overcharging the new, or the remaining original,
batteries.
 Undercharging the new, or remaining original,
batteries.
 Over discharging either the new or the remaining
original batteries.
 If you wish to only replace some of the batteries in
the pack, follow these steps for best results:
 Replacement batteries must always be of the
same battery manufacturer, model, and amp-
hour rating as the remaining batteries in the pack.
 Never mix batteries from different manufacturers
in the same pack.

 Fully charge both the new battery, and the
remaining original batteries. (specific gravity =
1.265 minimum, use a hydrometer)
 Use a replacement battery that is close to the
same age as the remaining original ones.
 Do not run the machine as long for about 20
cycles. For example, if you used to get 4 hrs
runtime, only run it for 2.5 hrs, and then charge
the batteries completely.
 Opportunity charge. Equalize after 30 days.
 The above steps will provide the best opportunity
for the new battery(s) to join the pack.
ACTIVATION OF DRY CHARGED
BATTERIES
NSS supplies some batteries in a “dry charged”
condition without any acid (electrolyte) in the battery.
The batteries cannot be used in this condition; they
must be activated by the addition of the battery acid
(electrolyte). Failure to follow this procedure will cause
severe damage to the batteries.
Materials Required
 1.265 Specific Gravity, Sulfuric Acid, to fill batteries.
 Rubber gloves and safety eye protection handling
Sulfuric acid.
 Plastic funnel to pour Sulfuric acid into batteries.
 Adjustable wrench and pliers to install battery cables.
Filling Procedure
 Remove the cap from each cell of the batteries.
 Fill each cell with Sulfuric acid fully to the bottom of
the access hole.
 Allow the batteries to absorb the acid for a period of
one hour. During this time the acid level in each cell
will drop and the batteries will become warm.
 Refill each cell with Sulfuric acid to a point 1/4” (6mm)
below the bottom of the access hole.
 Replace the cap in each cell of the batteries.
 Neutralize any spilled acid with bicarbonate of soda.
Rinse the battery case clean with clean water and dry
the battery case.
 Batteries are heavy - use two people to install.
 Refer to wiring diagram inside the battery
compartment. Align batteries in compartment as
shown on diagram.
 Install battery cables as shown on wiring diagram
 Tighten bolts and hex nuts with a wrench.
Caution: Do not short across two terminals with a
wrench.
 Loose or improper battery connections will cause
battery or machine damage and possible personal
injury.
 Connect the charger to the machine and allow it to
perform one complete charging cycle, (8 – 12 hours).
 Liquid level adjustment during the life of the batteries
should be made with distilled water.
If dry charged batteries have been filled with acid
(electrolyte) and are placed in storage, the batteries
must be recharged every 30 days to prevent damage.
BATTERY AUTO-FILL INSTRUCTIONS
WARNING: When working with Lead-Acid batteries
and Battery Acid observe all battery manufacturers’
safety precautions.
Caution: This option is not for well or tap water.
 Connect the regulated hose system to water supply.
Aim the purge into drain or bucket and turn on water
supply. When air is removed from the system
disconnect quick coupler by pushing the button
labeled CPC.
 Check the system for leaks by connecting the
regulated hose system quick connect to the Auto-Fill
quick connect. After connection the red balls in the
flow indicator will spin indicating water flow. When
the balls stop spinning check the system for leaks and
IMMEDIATELY disconnect the quick coupler.
 Place the dust cover over the male quick coupler on
the Auto Fill system. Turn off water supply and
remove the regulated hose system. Reinstall the
purge quick coupler and store in a safe place.
 We recommend you remove the hose swivel and
valve from one cell to check the electrolyte level after
the first fill.
Battery Charger
The onboard battery charger supplied with this machine
is capable of charging lead acid batteries from 185 to
350ah capacity. There is no need to change algorithms
or settings based on battery manufacturer, or battery
size.
The charger can also be set to charge flooded (wet)
cell, AGM, or Gel batteries. LED’s on the charger
indicate which type of battery the charger is set to
charge. One setting is for Flooded and (most) AGM
batteries, the other setting is only for Crown and Trojan
AGM and GEL batteries.
Depending on the battery charger model, the charger
can operate on 100/115/230 VAC 1ph 50/60 HZ power,
and will automatically detect these input voltages.
Before connecting the battery charger to power, check
the label on the battery charger to verify the proper
input power.
Determining Your Battery Type
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
WARRANTY.
Your machine may have been ordered with batteries
installed at the NSS factory. The standard battery type,
normally supplied by NSS, is the flooded (wet) cell lead
acid battery. Gel and AGM sealed batteries may also
be available at customer request.

Flooded (wet) batteries can be easily identified by the
removable cell caps. Removing the caps allows
inspection of the liquid electrolyte (sulfuric acid) level in
each cell.
AGM (Absorbed Glass Mat) batteries are sealed,
maintenance free batteries. The do not have cell caps
intended for removal. Look for “AGM” printed on the
tops or sides of the batteries.
Gel (gelled electrolyte) batteries are also sealed,
maintenance free batteries. They do not have cell caps
intended for removal. Look for “GEL” printed on the
tops or sides of the batteries.
Battery Charger Indicator LED’s
Your battery charger is equipped with LEDs that
indicate the following:
 Battery Type Setting. Either of these two LEDs will
be illuminated, anytime the charger is plugged in, to
signal which type(s) of batteries the charger is
configured to charge. The two options available are:
 Wet / AGM: When this LED is illuminated, the
charger is configured to charge either flooded
(wet), or AGM batteries.
 Gel Cell. When this LED is illuminated, the
charger is configured to charge Gel batteries
ONLY. EXCEPTION: Crown and Trojan AGMs
are to be charged with the Gel setting.
 State of Charge Indicators. Four additional LEDs
provide information about the charge level of the
batteries during charging.
o 30%, 60%, 90% and 100%.
 Fault Indications. During charging, the charger
provides feedback about the charge process and any
problems detected. It will provide feedback and
signal the type of problem by flashing LEDs as
described below:

Changing the Battery Type Setting
The standard setting for the onboard battery charger is
Flooded/AGM. EXCEPTION: If your machine was
ordered from NSS equipped with Crown AGM or Gel
batteries, then the charger was configured for Gel
batteries at the factory.
Configuring the Charger for Gel batteries:
1. Remove the top cover.
2. Pull the jumper off the 2-pin connector (position 1),
and then move the jumper to position 2 on only one
pin of the 2-pin connector. See photo below.
3. Reinstall the top cover.
Configure the Charger for Flooded/AGM batteries
1. Remove the top cover
2. Pull the jumper from the 2-pin connector, and install
the jumper at position 1 (on both pins of 2-pin
connector).
3. Reinstall the top cover.
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
WARRANTY.
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.
Equalizing the batteries (Flooded only)
The batteries should be equalized once every 30 days
to ensure maximum battery 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 2 hrs, 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 warranty. 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-CROWN
ANDTROJAN 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 cycle life.

 Trojan flooded cell
 US Battery flooded cell
 Deka flooded cell
 Crown gel
 Concord gel
 Discover AGM
Notes on LED indications per DoE compliance:
When first connected to DC (AC not connected), the LEDs will display one or more of the following:
 The LEDs will flash the charger’s ID code (this is for PCS internal use only). Once the LEDs flash the ID, they will
only display one yellow LED. This configuration will remain until AC is detected and a charge cycle is in progress.
 There is also a possibility the LEDs will not flash their ID code and only show a yellow LED.
 Lastly, the LEDs may not flash their ID code and may not show any LEDs until AC is detected.
If the AC line and neutral wires are reversed, the unit will wait 2 minutes before starting a charge. NOTE: The 2-
minute wait period will also be a factor if the charger is being powered by anything other than normal grid AC such
as a conventional generator, inverter, etc.
If the AC plug is disconnected during charge, the unit will turn off as expected. The user may hear some clicking
noise, but should not be alarmed. This is the Powered by Battery/DOE functionality checking for AC connection.
