[12.7mm] or less in length.
Failure to replace carbon brushes will cause poor
machine performance and possible motor damage.
Check the condition of the batteries.
A battery may be checked using a Hydrometer to
check the specific gravity (strength) of the acid in
each cell. Variations in readings occur due to the
chemical reaction taking place during use.
Always check the specific gravity when the battery
is fully charged.
Replace batteries as needed.

Every 12 Months (Every 1200 Hours)
Call your Authorized NSS distributor / Service
Station to have the following services performed.
Verify that all daily, weekly, monthly and quarterly
maintenance has been performed.
Inspect Drive Motor carbon brushes for wear.
This will require removing the drive motor from the
machine and should only be done by an authorized
NSS Service Station.
Using compressed air, blow the accumulated
carbon brush dust out of the motor.
Replace carbon brush when they measure ½”
[12.7mm] or less in length.
Failure to replace carbon brushes will cause poor
machine performance and possible motor damage.
Machine Jacking
Use the jacking locations as shown in the pictures
above. Use a jack and or jacks capable of supporting
the weight of the machine. Position the machine on a
flat level surface and block the wheels. Two jacks are
required for rear wheel removal, one on each side.
Gas Spring Service
ALWAYS secure Brush Head in the pad change
position using the strap provided before
attempting any maintenance or repairs to the gas
spring or coil spring assemblies.
Remove the spring clip that secures the gas spring
to the machine. Then pull the gas spring off of the
ball stud. There is a clip and ball stud at each end.
Place one end of the gas spring against a hard
surface and push on it. If you can compress it, it
must be replaced. If you cannot compress it, it is
most likely OK.

Pad Pressure Adjustment
The NSS eForce Burnisher is preset at the factory
for medium duty applications. It can be tuned to
your specific application for optimum
performance.
ONLY an authorized NSS Service Station should
perform this adjustment.
Tools required for Pad pressure adjustment
1) ¾ open end wrench
Set the pad pressure in
the middle of the amp
meter
Checking the Pad Motor Amperage
First install a new pad on the pad driver.
Caution: Checking the Amps with a used
pad will cause the machine to have high
amps when a new pad is installed.
Lower the Pad Motor into the operating position.
Turn on the Pad Motor switch and leave the Pad
Pressure on the low setting.
While running the machine, read the amp meter in
the Pad Motor section on the Main screen. The
amp meter should be reading in the middle of the
green area of the amp meter.
If adjustment is required, follow these
instructions.
It will be easier to access the lock nut and spring
guide rod assembly with the machine in the pad
change position.
First loosen the lock nut on the spring guide. With
the lock nut loose, the spring guide rod assembly
will be easily turned by grasping the set collar on
the spring guide rod.
Turn the spring rod guide assembly ½ to 1 turn at a
time. A little adjustment goes a long way.
Thread the spring guide rod assembly out of the
ball joint to decrease the pad pressure. Thread the
spring guide rod assembly into the ball joint to
increase the pad pressure.
Every time an adjustment is made check the amps.
This may require a few tries to get the Pad
Pressure were it should be.
After the adjustment is made tighten the lock nut
and redo the test. If it has not changed the process
is complete.
Fall back setting 
If your machine has come totally out of adjustment, or
you need to replace the Spring Rod Guide Assembly
you may need to start from the beginning.
The factory starting setting for the pad pressure is
3/4 of an inch [19mm] from the set collar to the lock
nut.
From this setting, proceed with the Pad Pressure
Adjusted.

17
Pushing Machine/Parking Brake
In the event the eForce Burnisher needs to be
pushed, the brakes need to be released. At the rear
of the machine, reach under the drive motor mount
and find two openings. In the left opening, reach
inside and pull the lever back. In the right opening,
push the lever forward. Now the machine can be
pushed.
If the operator tries to drive the machine with
the brakes disengaged the machine will not
move. The brake icon will appear in the pad
motor section of the main screen along with a
3A code in the service box.
To engage the brakes, push the lever forward in the
left opening, pull the lever back in the right opening.
Turn the machine off then back on the clear the
service code. The machine is now ready for use.
Storing Machine
The following steps should be taken when storing the
machine for extended periods of time.
Park the machine on a flat level surface.
Park the machine in a cool, dry area. Do not
expose to rain. Store indoors.
Raise the burnishing head into the pad change
position.
Remove the batteries, or charge them every three
months.
Transporting the Machine
When transporting the machine by use of trailer or
truck, carefully follow the loading and tie down
procedures:
Raise the burnishing head to the transport position
and secure the strap. Caution: Be sure the pad
motor is in the off position before moving the
machine. The pad motor can run in this position.
Load the machine using a ramp that can support
the weight of the machine and operator. Caution:
Do not attempt to climb a ramp or incline that
exceeds a 13% (7.41 degrees) grade level. A
winch must be used when incline exceeds a 13%
grade level.
Once loaded, turn off the key switch.
Block the rear wheels front and back.
Secure the front and back of the machine with tie
down straps. Put the tie down straps in the pallet
bracket holes on each side and run them forward
to prevent the machine from twisting in transit.
From the rear of the machine, run one tie down
strap around the machine just above the foot plate
and back behind the machine. This will prevent the
machine from moving forward and backward
during transit.

Battery Installation
FOR SAFETY: When servicing batteries,
wear appropriate personal protection
equipment as needed. Avoid contact with
battery acid.
Turn off all switches. Disconnect battery pack from
the machine.
Remove the rear panel.
There are two nuts (one in each corner) on top of
the rear panel inside the battery compartment and
three screws at the outside bottom of the cover.
Tip the cover back and then lift up on an angle.
Batteries are heavy – ALWAYS use two people to
install batteries into machine.
Refer to wiring diagram located on the underside of
the seat plate. Align batteries in compartment the
same as the old batteries or as shown on diagram.
Install battery cables the same as they were on the
old batteries or as shown on wiring diagram.
NSS recommends replacing the battery cables
when replacing batteries.
Tighten bolts and hex nuts with a wrench.
Install terminal boots over terminals to complete
installation.
CAUTION: Do not short across two terminals
with a wrench.
CAUTION: Loose or improper battery
connections will cause battery or machine
damage and possible personal injury.
Battery charger
The battery charger supplied with this machine is
capable of charging lead acid batteries from 350 to
435 ah capacity.
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. 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. They 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 not
recommended for use with this machine.

19
Operating the Battery Charger
The battery charger is fully automatic. Simply plug
the charger into a suitable wall outlet, and the
charger will charge the batteries. The amp meter on
the right side will start with high amp output and drop
to 0 when 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 for maximum battery runtime and life.
To equalize the batteries:
Plug in the charger, and fully charge the batteries.
Unplug the charger from the wall outlet, then plug it
back in.
The charger will run holding the batteries at a
constant voltage, and equalizing each cell.
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. This
extra charging time will help raise the operating
voltage of the batteries, and will help ensure
maximum runtime and cycle life.
See Operating Battery Charger Instructions or
Monthly Maintenance for equalizing your
batteries especially if you have been opportunity
charging your machine.
Battery Replacement Notes
Entire Pack.
oIt is always recommended to replace all batteries
in the pack at the same time.
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.
oIf 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 3 hrs.
run time, only run it for 2 hrs., and then
charge the batteries completely.
Opportunity charge whenever possible.
Equalize after 30 days (Flooded only).
The above steps will provide the best
opportunity for the new battery(s) to join the
pack.
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 warranty. They can tell if this
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.
j. ALWAYS equalize the batteries (Flooded only)
every 30 days.
k. NEVER OVER DISCHARGE!
l. NEVER charge GEL batteries.
If contact with battery acid occurs:
Skin – Rinse with cold water for 15 minutes.
Eyes – Flush with cold water for 15 minutes.
Internal – Drink lots of water or milk. Seek medical
attention immediately.
