PREPARING THE MACHINE
Installing the Batteries:
Turn off all switches 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.
Warning
: Do not short across two terminals with
a wrench. Possible personal injury may occur.
Loose or improper battery connections will cause
battery or machine damage and possible personal
injury.
Charge the batteries before use!
Battery Charging
To recharge the batteries, plug the charger cord,
located at the rear of the machine, into an electrical
outlet (100/115/230 50/60HZ VAC).
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.
Make sure the drain plug of the recovery tank is
closed tightly and in its holding clip.
Put 1 to 2 gallons [3.8 to 7.6 L] of clean water into the
solution tank first to help dilute the chemicals and
prevent excess foaming. 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.
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 of this machine.
Consult your local NSS distributor for application
recommendations.
Turn the pad driver upside down on the floor and
remove the pad holding cup.
Remove the center cutout of the 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 deck into the transport position.
Align the slots of the pad driver with the lugs of the
drive casting.
Turn the pad driver until it snaps into the clip.
Install a Brush:
Raise the brush deck into the transport position.
Align the slots of the brush with the lugs on the drive
casting.
Turn the brush until it snaps into the clip.
Install the squeegee assembly:
Place the squeegee lift handle in the storage (up)
position.
The squeegee assembly mounts to a metal bracket at
the rear 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 “breakaway” 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.
Operating the Machine
The Wrangler 2616 DB has the brush deck offset to the
right side of the machine. This offset allows you to
clean the edge of a floor or an obstructed area (walls or
shelving) with the right side of the machine.
