MACHINE OPERATION

General Information

The CHAMP 3329 is very maneuverable and is designed to
clean as you drive the machine. Follow these steps to
prepare the machine for daily operation.

 Always sweep or dust mop the floor of debris 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 number of turns as possible.

 Remove as many obstacles as possible from the area to

be cleaned.

 Place “Wet Floor” warning signs in area being cleaned.
 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).
 Pour all liquids through the mesh filter at the left side of

the solution tank.

 Fill with clean water, up to 29 gallons.
 Add the cleaning chemicals to the solution tank.

Prepare the Recovery Tank:

 Always use a defoamer to protect the vacuum motor of

this machine. We recommend that you add at least 4 to
6 ounces of defoamer chemical.

 Vacuum the defoamer into the recovery tank through the

vac hose.

 Make sure that the drain plug of the recovery tank hose is

closed tightly.

Install a Pad Driver and Pad:

 There is a wide range of pads or brushes available for the

many cleaning applications of this machine. See the
“Accessories” page in the Parts List manual.

 Pull pin and open skirt.
 Turn the pad driver upside down on the floor and remove

the pad holding cup.

 Remove the center cutout of the 17” pad and 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 motor into the transport position (center

position of switch).

 Align the lugs of the pad driver with notches of the drive

casting.

 Turn the pad driver to lock onto the drive casting.
 Close the locking latch.
 Close the skirt.
 Repeat for the other side.

Install a Brush:

 Pull pin and open skirt.
 Raise the brush motor into the transport position.
 Align the lugs of the brush with the notches of the drive

casting.

 Turn the brush to lock onto the drive casting.
 Close the locking latch.

 Close the skirt.

Install the Squeegee Assembly:

 Loosen the two mounting knobs and slide the squeegee

assembly onto the mounting plate.

 Hand-tighten the mounting knobs. Do not use pliers to

tighten the knobs, as this will defeat the “breakaway”
design.

 As the machine is used, the squeegee blades wear out,

and need to be replaced due to damage.

 Squeegee blades should lie over (like a window

squeegee) whenever the machine is moving forward.

 Do not add any weights or other pressure to the

squeegee mechanism; it will not improve the
performance or service life.

 The squeegee rises automatically when the machine is in

reverse.

 Squeegee springs add pressure to floor. There are 3

adjustments available by moving the end of the spring
closest to the frame from hole to hole. More pressure is
added the further away the hole is from the center point.
When changing the pressure always move both sides,
using the same distance (hole) on each side.

 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.

NOTE: Remove squeegee, brushes or pad drivers, and
side skirts if transporting to different places or loading /
unloading into a truck or trailer.

Install the batteries:

Turn off all switches and tilt the battery compartment lid



open to expose battery compartment.

https://harrissupplyind.com - To Order Parts Call 608-268-8080

****CAUTION****
Inspect and replenish battery water in every cell in every
battery weekly. Failure to maintain proper electrolyte
level in every cell of every battery will cause premature
battery failure, and void the warrantee.

Monthly Maintenance (Every 100 Hours)
 Verify that all daily and weekly maintenance has been

performed.

Equalize your batteries (Flooded only). To equalize the



batteries, after they have been fully charged, unplug the
charger (from the wall outlet), and plug it back in. The
charger will skip thru the first few phases of the charge
cycle, and run thru the finish phase. This will balance out
all the cells in the batteries, and provide maximum battery
life. THIS STEP IS ESPECIALLY IMPORTANT IF YOU
PRACTICE OPPORTUNITY CHARGING (see page 8).

 Clean filters by rinsing with cool, clear water. Dry

Completely.

After every 750 Hours of Operation:
 Inspect the drive motor carbon brushes for wear.

Replace the brushes when they are 3/8 in. (9mm.) in
length.

 Inspect the brush drive motor carbon brushes for

wear. Replace the brushes when they are 1/2 in.
(13mm.) in length.

 Inspect the vacuum motor carbon brushes for wear.

Replace the brushes when they are 7/16 in. (11mm.)
in length.

Battery Replacement Notes

 Entire Pack.

o It is always recommended to replace all batteries in

the pack at the same time.

 One or more batteries out of the pack. This is not

recommended. Replacing just one or two batteries out of
the pack can lead to the following:

 Overcharging the new, or the remaining

original, batteries.

 Undercharging the new, or remaining original,

batteries.

 Over discharging either the new or the

remaining original batteries.

o If you wish to only replace some of the batteries in the

pack, follow these steps for best results:
 Replacement batteries must always be of the same

battery manufacturer, model, and amp-hour rating
as the remaining batteries in the pack.

 Never mix batteries from different manufacturers in

the same pack.

 Fully charge both the new battery, and the

remaining original batteries. (s.g. = 1.265
minimum, use a hydrometer)

 Use a replacement battery that is close to the

same age as the remaining original ones.

 Do not run the machine as long for about 20

cycles. For example, if you used to get 4 hrs
runtime, only run it for 2.5 hrs, and then charge the
batteries completely.

 Opportunity charge whenever possible.
 Equalize after 30 days.

(Flooded only)

Battery Charger

The onboard battery charger supplied with this machine
is capable of charging lead acid batteries from 185 to
350ah capacity. There is no need to change algorithms
or settings based on battery manufacturer, or battery
size.

The charger can also be set to charge flooded (wet) cell,
AGM, or Gel batteries. LED’s on the charger indicate
which type of battery the charger is set to charge. One
setting is for Flooded and AGM batteries, the other
setting is only for GEL batteries.

Depending on battery charger model, the charger can
operate on 100/115/230 VAC 1ph 50/60 HZ power, and
will automatically detect these input voltages. Before
connecting the battery charger to power, check the label
on the battery charger to verify the proper input power.

Determining Your Battery Type

CAUTION: DIFFERENT BATTERY TYPES HAVE
DIFFERENT CHARGING REQUIREMENTS. FAILURE
TO PROPERLY IDENTIFY YOUR BATTERY TYPE
AND SET THE CHARGER ACCORDINGLY WILL
RESULT IN BATTERY DAMAGE, AND VOID THE
WARRANTEE.

Your machine may have been ordered with batteries
installed at the NSS factory. The standard battery type,
normally supplied by NSS, is the Flooded (wet) cell lead
acid battery. Gel and AGM sealed batteries may also be
available at customer request.

Flooded (wet) batteries can be easily identified by the
removable cell caps. Removing the caps allows
inspection of the liquid electrolyte (sulfuric acid) level in
each cell.

AGM (Absorbed Glass Mat) batteries are sealed,
maintenance free batteries. The do not have cell caps
intended for removal. Look for “AGM” printed on the
tops or sides of the batteries.

Gel (gelled electrolyte) batteries are also sealed,
maintenance free batteries. The do not have cell caps
intended for removal. Look for “GEL” printed on the
tops or sides of the batteries.

Battery Charger Indicator LED’s

Your battery charger is equipped with LEDs that indicate
the following:

 Battery Type Setting. Either of these two LEDs

will be illuminated, anytime the charger is
plugged in, to signal which type(s) of batteries
the charger is configured to charge. The two
options available are:

o Wet / AGM: When this LED is

illuminated, the charger is configured to
charge either flooded (wet), or AGM
batteries.

o Gel Cell. When this LED is illuminated,

the charger is configured to charge Gel
batteries ONLY. EXCEPTION: Trojan

https://harrissupplyind.com - To Order Parts Call 608-268-8080

AGMs are to be charged with the Gel
setting.

 State of Charge Indicators. Four additional

LEDs provide information about the charge level
of the batteries during charging.

o 30%, 60%, 90% and 100%.

 Fault Indications. During charging, the charger

provides feedback about the charge process
and any problems detected. It will provide
feedback and signal the type of problem by
flashing LEDs as described below:

Changing the Battery Type Setting

The standard setting for the onboard battery charger
is Flooded/AGM. EXCEPTION: If your machine was
ordered from NSS equipped with Gel batteries, then
the charger was configured for Gel batteries at the
factory.

Operating the Battery Charger

CAUTION: DIFFERENT BATTERY TYPES HAVE
DIFFERENT CHARGING REQUIREMENTS.
FAILURE TO PROPERLY IDENTIFY YOUR
BATTERY TYPE AND SET THE CHARGER
ACCORDINGLY WILL RESULT IN BATTERY
DAMAGE, AND VOID THE WARRANTEE.

The battery charger is fully automatic. Simply plug
the charger into a suitable wall outlet, and the
charger will charge the batteries. The green 100%
LED will be continuously illuminated when the charge
cycle is complete.

A bubbling, or boiling sound coming from the
batteries during the last few hours of the charge is
normal. The batteries may be warm, but not too hot
to touch.

Equalizing the batteries (Flooded only)

The batteries should be equalized once every 30
days to ensure maximum battery life.

To equalize the batteries:

 Plug in the charger, and fully charge the

batteries (until the green 100% LED is on
continuously).

 Unplug the charger from the wall outlet,

then plug it back in.

 The charger will run for 2hrs, holding the

batteries at a constant voltage, and
equalizing each cell.

Battery Do’s and Don’ts:

a. You do not have to fully discharge the batteries

before charging. They do not have a “memory”.

b. Plug the charger in anytime the machine is not in

use.

c. NEVER let the electrolyte level fall below the tops

of the plates (flooded cell batteries). This will
damage your batteries almost immediately, and
void the battery warrantee. It will be evident if this
has happened.

d. NEVER refill the batteries with well or tap water

(flooded cell batteries).

e. NEVER overfill the batteries (flooded cell

batteries).

f. NEVER let the batteries sit discharged overnight

(or between shifts).

g. ALWAYS check the electrolyte level about every 3

or 4 charge/discharge cycles BEFORE
CHARGING.

h. ALWAYS refill the batteries with distilled water (if

needed) AFTER CHARGING.

i. ALWAYS fully recharge the batteries after use

(until the green LED comes on).

j. ALWAYS equalize the batteries every 30 days

(Flooded only).
k. NEVER OVER DISCHARGE!
l. NEVER charge GEL batteries with the charger set

to FLOODED/AGM.
m. NEVER charge FLOODED/AGM batteries with the

charger set to GEL. EXCEPTION-TROJAN

AGM’S TO BE CHARGED WITH GEL SETTING.

Opportunity Charging

Opportunity charging is charging the batteries when
an opportunity presents itself, such as during breaks,
and is done in addition to a full charge cycle.
Opportunity charging is recommended, as this extra
charging time will help raise the operating voltage of
the batteries, and will help ensure maximum cycle
life.

NOTE: Trojan AGM batteries should be charged with
the GEL setting.

**The charger has been tested on batteries from the
following manufacturers:

 Trojan flooded cell
 US Battery flooded cell
 Deka flooded cell
 Crown gel
 Concord gel
 Discover AGM
