Squeegee Assembly
The squeegee assembly is available in both straight
and curved. The straight squeegee uses a dual (2)
Linatex blade system. The "curved" squeegee has a
Linatex rear blade and a neoprene front blade.
Side Skirt Assemblies
This machine is equipped with left and right side skirt
assemblies. The side skirt assemblies are designed to
contain the liquids in the cleaning area under the
machine; they channel the liquids toward the squeegee,
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.
