MACHINE OPERATION
General Information
The Wrangler 26 is very maneuverable and is
designed to scrub floors as you operate the machine
from behind. Alwaysdust 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 turn’s possible. Remove as many
obstacles as possible from the area to be scrubbed.
Consult your local NSS distributor for more complete
procedures and chemical advice.
Preparing the machine for use
Prepare the solution tank:
•Never use water over 140°F (60°C) degrees.
Excessively hot water may damage components
such as the tanks.
•Pour all liquids through the round 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.
•Consult your local 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.
Prepare the recovery tank:
•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. 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.
To install a 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 authorized
distributor for application recommendations.
•Turn the pad drivers upside down on the floor and
remove the pad holding cup.
•Remove the center cutout of the 13" (33 cm.) 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 motors into the transport position.
•Align the lugs of the pad driver with the slots of the
drive casting.
•Turn the lug of the pad driver toward the latch; close
the latch around the lug to lock onto the drive casting.
To 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 lug to lock onto the drive casting.
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 pliers to
tighten knobs as this will defeat the “break-away”
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.
•Turn the vacuum motor ON and open the water valve
slightly.
•Squeegee blades should lay over slightly (like a
window squeegee) when the machine is moving
forward or reverse.
•Adjust the blade angle by turning the wing nut (or
knob) on the pivot arm clockwise or counterclockwise.
•Do not add any weights or other pressure to the
squeegee mechanism, it will not improve the
performance and will shorten service life.
To install the side skirts:
•Position the skirts at the left/right side of the machine.
•Remove the skirt retaining pins from the mount
bracket.
•Align the side skirt holes with mount bracket holes,
insert and secure retaining pins. Close side skirts
around machine and secure with skirt latch.
•The side skirt wiper blades will naturally wear with
use and require adjustment or replacement.
To adjust side skirt wiper blades:
•Install the side skirts on the machine.
•Loosen the retaining strip screws.
•Pull down evenly on the entire length of wiper blade
so that it firmly touches the floor.
•Tighten all screws and test run machine for splashing
under the blades.
•DO NOT adjust blades too low, as it will cause
damage and excessive wear to the blades.

To replace side skirt wiper blades:
•Remove the side skirt assembly from the machine.
•Remove the retaining strip and screws.
•Remove the old wiper blade and replace with a
new blade.
•Replace the retaining strip and screws, do not
tighten.
•Pull down evenly on the entire length of wiper
blade so that it firmly touches the floor.
•Tighten all screws and test run machine for liquid
splashing under the blades.
•DO NOT adjust blades too low, as it will cause
damage and excessive wear to the blades.
Operating the Machine
The Wrangler 26 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.
•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.
•Overlap each cleaning path about 2 in. (5 cm.) to
prevent streaking and dirty areas.
Normal Cleaning
•Fill solution tank as directed.
•Put defoamer chemical in recovery tank.
•Install pad drivers / pads or brushes.
•Close and secure side skirts.
•Install squeegee assembly.
•Move machine to area to be cleaned.
•Sweep and dust mop area to be cleaned.
•Place warning signs “Wet Floor” in area.
•Turn on master switch.
•Turn on brush and vacuum motor switches.
•Place brush motors and squeegee assembly in
operating position on floor.
•Twist the handle grips forward (away from you) to
move forward and backward (toward you) to move
backward.
•Lift solution valve handle to adjust liquid flow to
floor. Adjust amount of flow as needed. Close the
solution valve completely 10 ft. (3m.) before you
turn at the end of each cleaning path. This will
reduce the amount of liquid on the floor when you
make the turn. Open the solution valve when you
have started your next cleaning path. Repeat this
procedure on each path.
•Watch the level of liquid in the recovery tank and
listen for the float shut-off to change the sound of the
vacuum motor. When the vacuum airflow stops, you
must turn off the vacuum motor and then 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
Wrangler 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.
•Resume cleaning operation. Refill solution tank and
empty recovery tank as needed.
•When cleaning is complete, return machine to
storage area and perform daily maintenance.
Special Cleaning
The Wrangler 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. Best results are
achieved by placing the brush motors in the heavy
scrub position.
•NOTE: The floor surface becomes extremely slippery
in this operation. The Wrangler should be operated
only in low 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. The Wrangler should be
operated only in low to medium speed and great care
should be taken when walking on this wet surface.
