****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 warranty.
Monthly Maintenance (100 hours)
 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.
 Verify all daily and weekly maintenance has been
performed.
 Inspect vacuum motor exhaust filter behind metal plate
at rear of battery compartment. Clean or replace as
necessary.
 Check casters for wear or damage.
 Grease the caster axle and swivel bearing. Use a
hand-held grease gun and a high grade of water-
resistant lithium base grease.
 Inspect all mechanical linkages, pivot points and ball
joints for freedom of movement. Use a penetrating
spray lubricant that is water resistant. Do not use WD-
40 lubricant.
 Inspect all fasteners (bolts, screws, nuts) at
mechanical linkages, pivot points and ball joints for
tightness. Tighten as needed.
 Repair or replace any worn or damaged components.
 Inspect the squeeze tube in the Sidekick Chemical
dispenser for cracks or leaks.
Mandatory Periodic Maintenance
It is important for you to read the hour meter for hours
used in order to perform this machine maintenance.
It is mandatory that the following maintenance
procedure be performed at the described interval.
Failure to perform this procedure may result in poor
machine performance, machine component damage and
failure. This procedure should be performed by an NSS
authorized distributor or service center. Repairs
performed by an unauthorized company will void the
machine warranty. If you require assistance finding an
authorized service center, please contact NSS
Enterprises, Inc.
After every 450-500 hours of operation you must inspect
vacuum motor carbon brushes for wear. Replace the
vacuum motor carbon brushes when they are 7/16in.
(11mm) in length.
After every 650-700 hours of operation you must inspect
drive motor (transaxle) carbon brushes for wear.
Replace the drive motor (transaxle) carbon brushes
when they are 3/8in. (9mm) in length.
After every 650-700 hours of operation you must inspect
brush motor carbon brushes for wear. Replace the
brush motor carbon brushes when they are 1/2in.
(13mm) in length.
Battery Replacement Notes
 Entire Pack.
It is always recommended to replace all batteries in
o
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.
If you wish to only replace some of the batteries in
o
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. (specific gravity =
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 4hrs
runtime, only run it for 2.5hrs, and then charge
the batteries completely.

Opportunity charge whenever possible (see
page 12).

Equalize after 30 days (Flooded only).

The above steps will provide the best
opportunity for the new battery(s) to join the
pack.
