Rinsing after use in a wax floor stripping application is
highly recommended.
 Allow to air dry, it can be stored on top of the machine
for drying.
 Inspect the squeegee assembly, linkage, and vacuum
hose, for wear, damage or obstruction. Repair or
replace as needed.
 Remove debris from squeegee hose and entrance to
recovery tank.
Weekly Maintenance (20 Hours)
 Verify all daily maintenance has been performed.
 Check all battery terminal and cable connections.
Tighten as needed. Loose connections are dangerous
and can cause personal injury and machine damage.
 Clean any corrosion from battery terminals and
cables.
 Drain all liquids from battery compartment. Dispose
of according to local and federal regulations.
 Check solution flow to pad drivers / brushes. Remove,
inspect and clean the solution filter assembly.
 Flush clean solution tank and hoses with a mixture of
8 oz. (250ml.) white vinegar to one-gallon (4 liter)
warm water.
 Repair or replace any worn or damaged components
as needed.
 Inspect the squeeze tube in the Sidekick Chemical
dispenser for cracks or leaks.
****CAUTION**** Inspect and replenish water in every
cell of every battery weekly. Failure to maintain proper
electrolyte level in all cells will cause premature battery
failure and void the warranty.
Monthly Maintenance (100 Hours)
 Verify all daily and weekly maintenance has been
performed.
 Inspect vacuum motor filter under metal plate on top
of recovery tank. Clean or replace as necessary.
 Check casters for wear or damage.
 Grease both pillow block bearings on the drive axle
and the caster swivel bearings. Use a hand held
grease gun and a high grade of water resistant lithium
base grease.
 Lubricate the drive chain and sprockets with a
foaming spray type lubricant. A motorcycle spray
type chain lube would be appropriate.
 Do not use your finger to apply lubricant.
 Check chain tension, and adjust as needed. Check
chain tension by squeezing the chain midway
between the sprockets. The chain should flex 1/4"
(6mm) on each side.
 Adjust chain tension by loosening the four (4) hex
bolts of the drive motor mount. Slide the drive motor
toward the drive wheel to loosen chain. Slide drive
motor away from the drive wheel to tighten the chain.
Tighten all four hex bolts.
 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.
 Check Return Spring of the twist grip handles. If it
appears weak or does not return the twist grips to the
neutral position, replace spring.
 Inspect all fasteners (bolts, screws, nuts) at
mechanical linkages, pivot points and ball joints for
tightness. Tighten as needed.
 Equalize the batteries (flooded cell only).
 Clean polyethylene body components to remove
chemical and liquid residue and maintain a "like new"
appearance.
 Remove top cover plate and clean the filter. Replace
filter as required.
 Repair or replace any worn or damaged components.
 Tighten and Lube the drive motor chain.
Mandatory Periodic 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 carbon brushes for wear
Replace the drive motor 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
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.
