IMPORTANT SAFETY INSTRUCTIONS
GROUNDING OF ELECTRICAL EQUIPMENT
WARNING: Improper connection of the equipment–grounding
conductor can result in a risk of electric shock. Check with a qualified
electrician or service person if you are in doubt as to whether the outlet
is properly grounded. Do not modify the plug provided with the machine
– if it will not fit the outlet, have a proper outlet installed by a qualified
electrician.
Always use a properly grounded 3-wire extension cord which has
male and female plugs. If 25 foot extension cords are used, the
electrical carrying capacity should be no less than 14-3 ST. For 50’
foot extension cords no less than 12-3 ST.
GROUNDING INSTRUCTIONS
This machine shall be grounded while in use to protect the operator from electric shock. The machine is provided
with a three-conductor cord and a three-contact grounding type attachment plug. The plug must be plugged into
an appropriate outlet that is properly installed and grounded in accordance with all local codes and ordinances.
The green conductor in the cord is the ground wire. Never connect this wire to anything other than the grounding
pin of the attachment plug.
Check nameplate on the machine to be sure voltage and cycle stated is the same as the electrical outlet. Do not
attempt to plug a 120 volt machine into a 240 volt outlet or a 240 volt machine into a 120 volt outlet. If the
machine is provided with an attachment plug as shown in Figure A below, it is intended for use on a nominal 120
volt circuit. If a properly grounded receptacle as shown in Figure A is not available, an adapter may be installed
as shown in Figure B if the outlet box that houses the receptacle is grounded. Be sure to fasten the grounding tab
(the green colored rigid ear, lug or the like extending from the adapter) with a metal faceplate screw.
If the machine is provided with an attachment plug as shown in Figure C, it is intended for use on a nominal 240
volt circuit. No adapter is available for this plug.

MACHINE COMPONENTS
Solution Tank
The solution tank is the lower part of the machine
body. It has a capacity of 8 gallons (30 liters).
•The amount of water in the tank is measured by the
sight hose, (clear plastic tube), at the rear of the
machine.
Recovery Tank
The recovery tank is the upper part of the machine
body. It has a capacity of 10 gallons (38 liters).
•A rectangular, clearview lid assembly closes the
recovery tank.
•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.
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 red switch is the master power switch; it
controls the power to all components
Squeegee Assembly
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.
Brush Gear Motor
This machine has one (1) 24-volt brush motor located
at the front of the machine. The motor is attached to
a gearbox to turn the pad drivers or brushes.
•This motor has carbon brushes that must be
serviced on a regular basis. The carbon brushes
have an expected life of 2,000 operating hours.
Refer to the maintenance section later in this book.
Vacuum Motor
This machine has a 24-volt vacuum motor.
•The vacuum motor is attached to the underside of
the solution tank behind the rubber flap.
•This motor has carbon brushes that must be
serviced on a regular basis. The carbon brushes
have a maximum expected life of 700 operating
hours. Refer to the maintenance section later in
this book.

PREPARING THE MACHINE
•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 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.
•Make sure the recovery tank drain hose is tight on
the plug.
•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. Consult your
NSS authorized distributor for 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.
•Remove pad driver assembly from drive casting on
end of brush motor shaft by turning the driver
counter-clockwise.
•Turn the pad drivers upside down on the floor and
remove the pad holding cup.
•Remove the center cutout of the 17” (43cm) or 20”
(51cm) 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.
•Turn the pad driver counter-clockwise to remove.
Install a Brush:
•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.
•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.
Operating the Machine
The Wrangler 1708/2008 is very maneuverable and
is designed for light to medium scrubbing as you
operate the machine from behind. Follow these
steps to prepare the machine for daily operation.
•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 amounts of turns as possible,
overlapping each cleaning path about 2 in. (5cm) to
prevent streaking and dirty areas.
•Remove as many obstacles as possible from the
area to be scrubbed.
•Do not put strip solution in solution tank. Apply
with mop and bucket and rinse with clean water in
solution tank.
