DAILY USE
The Wrangler 1708/2008 is very maneuverable and is
designed to scrub floors as you operate the machine
from behind. Always dust mop the floor before
scrubbing. 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. Remove as many obstacles
as possible from the area to be scrubbed. The Wrangler
1708/2008 is designed for light to medium scrubbing.
Consult your local NSS distributor for more complete
procedures and chemical advice.
MACHINE COMPONENTS AND
OPERATION
Battery Package (see safety instructions)
The Wrangler 1708/2008 is a 24 volt system with two
(2) 12 volt, 115 amp hour batteries. Consult your local
NSS authorized distributor for application
recommendations.
To install the batteries:
•Batteries are heavy, use two people to install.
•Turn off all the switches.
•Empty all liquids from recovery tank.
•Step on foot pedal at front of machine to release tanks.
Lift tanks up and tilt back to rest on handles.
•Refer to wiring diagram on bottom of tanks. Align
batteries in compartment as shown on diagram.
•Install battery cables as shown on wiring
diagram. Tighten all bolts and hex nuts with a wrench.
•CAUTION: Do not touch two terminals with a wrench.
•Loose or improper battery connections will cause
battery or machine damage and possible
personal injury.
To charge the batteries:
•Charge machine after every shift or whenever batteries
are 75% expended.
•Turn off all the switches.
•Disconnect battery connectors below user control
panel.
•Connect lower connector from batteries to
connector from automatic battery charger.
•Needle on charger gauge should jump within 30
seconds to working level.
•Needle on machine battery gauge should not move
when machine is plugged into charger –batteries will
not be charged.
•NSS supplied battery chargers are automatic and
will shut off when charging cycle is complete.
Solution Tank
The solution tank is the lower part of the machine
body. The tank has a capacity of 8 gallons (30
litters) and is filled by pouring the water and cleaning
chemicals through the mesh covered opening and
filter at the front of the machine. Drain the solution
tank through the solution valve or the sight hose at
the rear of the machine.
To prepare the solution tank:
•Never use water over 140°F (60°C).
Excessively hot water may damage components
such as the tanks.
•Pour all liquids through mesh filter at the front of
the solution tank.
•Put 1 to 2 gallons of clean water into the solution
tank first to help dilute the chemicals and prevent
excess sudsing.
•Do not put strip solution in solution tank. Apply
with mop and bucket and rinse with clean water in
solution tank.
•Consult your local NSS distributor for complete
chemical advice. Dilute the cleaning chemicals
according to the manufacturer’s instructions.
•Add the cleaning chemicals to the solution tank
and fill with water as needed.
Recovery Tank
The recovery tank is the upper part of the machine
body. The tank has a capacity of 10 gallons (38
liters). The recovery tank is closed by a rectangular,
clearview lid assembly. The recovery tank has a
foam-sensitive float shut-off assembly. As the water
or foam level rises, the float ball will rise and shut off
the air flow of the vacuum motor to the squeegee. It
does not shut off the vacuum motor. Drain the
recovery tank through the black hose at the rear of
the machine.
To prepare the recovery tank:
•Always use a defoamer to protect the vacuum
motor of this machine. 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.
•Make sure the recovery tank drain hose is tight on
the plug.

Squeegee Assembly
The squeegee assembly is packed in a box inside of
the main shipping carton. Remove the squeegee
assembly from the box and inspect for concealed
damage. The squeegee assembly has a wide, flat
frame to help prevent damage, two ( 2) mounting
knobs, and two (2) small wheels to prevent “rollover”
in reverse.
To install the squeegee assembly:
•Place the squeegee lift arm in the storage (up)
position.
•Loosen the two mounting knobs and slide the
squeegee assembly onto the mounting plate. The
roller wheels must face the operator.
•Hand tighten the mounting knobs. Do not use tools
to tighten the knobs as this will defeat the
“breakaway” design.
To adjust the squeegee assembly:
As the machine is used, the squeegee blades will
wear or need to be replaced due to damage. Some
adjustment may be needed.
•Squeegee blades should lay over slightly (like a
window squeegee) when the machine is moving
forward or in reverse.
•Adjust the blade angle by turning the wing nut on
the pivot arm clockwise/counterclockwise.
•Do not add any weights or other pressure to the
squeegee mechanism. It will not improve the
performance or service life.
To install a brush or pad driver and pad:
There are 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 off all switches and empty all liquids from the
recovery and solution tank.
•Raise the brush motor into the “up”
position. The foot pedal is at the rear left of the
machine. Step on the pedal and slide it to the right
into the notch.
•Step on the foot pedal latch at the front of the
machine chassis.
•Lift the machine body by the opening for the
solution tank. Tilt the machine body backward until
the handles rest on the floor.
For BRUSH Attachment:
•Align the notches of the brush with the lugs of the
drive casting.
•Turn the brush clockwise to lock onto the drive
casting.
•Turn the brush counter-clockwise to remove.
For PAD DRIVER and PAD Attachment:
•Remove pad driver assembly from drive casting
on end of brush motor shaft by turning the driver
counter-clockwise.
•Turn the pad driver upside down on the floor.
Remove the pad holding cup.
•Remove the center cutout of the 17” (43cm) or 17”
(43cm) pad if present and place 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.
•Align the notches of the pad driver with the lugs of
the drive casting.
•Turn the pad driver clockwise to lock onto the drive
casting.
Control Panel
The operator control panel is located at the rear area
of the machine. This panel has components that
control various machine functions.
Starting from the left side:
•The circuit breaker is for both the brush motor and
the vacuum motor.
•The first switch turns the brush motor on and off .
•The next switch turns the vacuum motor on and
off.
•The battery meter shows the state of charge of the
batteries during operation.
