MACHINE MAINTENANCE

Routine maintenance is critical to ensure proper
machine operation and cleaning performance.
Perform all maintenance procedures as follows.
Always turn OFF all machine switches before
performing any maintenance.

Daily Maintenance

Battery Charging
• All power switches must be turned to the OFF
position.
• You must recharge the batteries at the end of
every work shift or when the battery meter
indicates "recharge" during the work shift.
• Connect the battery charger plug (red) to the
machine charging plug.
• Connect the battery charger power cord into a
grounded A.C. outlet of the proper voltage.
• After a few seconds the amp meter will indicate
the battery charger is operating.
• When the recharge cycle is complete, the battery
charger will turn off automatically.
• If the battery charger will not start operating, check
the charging plug connections, the battery cable
connections and the battery voltage.
• If the batteries have been discharged (used) too
deeply, the battery charger will not start. Consult
your local NSS service center for assistance.
Battery Electrolyte (liquid) Level
• Inspect the electrolyte level of at least one cell in
each battery before charging. The liquid must be
visible above the internal plates. Do not charge
the batteries if liquid is below the plates.
• Add only water to the cell of a battery to adjust the
liquid level. Before charging, add only enough
water to cover the top of the internal plates. After
charging add only enough water to bring the level
to the bottom of the fill tube.
• Do not overfill the battery liquid, this will cause
electrolyte (acid) spill. Spilled electrolyte can
cause machine damage and personal injury.
Clean and dispose of spills immediately.
Solution and Recovery Tanks
• Empty all liquids from both solution and recovery
tank.
• Rinse both tanks with clean water to prevent
chemical residue build-up. Empty both tanks.
• Leave recovery tank clear lid open to allow tank to
air dry and prevent odors.
Pad driver or brush
• Remove pad driver or brush from machine.
• Rinse with clean water to prevent chemical build-
up. Allow to air dry on shelf or rack.
• Inspect for wear or damage. Repair or replace as
needed.

Weekly Maintenance

• Verify all daily maintenance has been performed.
• Inspect battery liquid level, adjust to proper level as
needed.
• Check battery terminals and cable connections. Tighten
and remove corrosion as needed.
• Inspect and empty battery compartment drain hose as
described earlier in manual.
• Inspect and clean float screen and small vac filter above
float.
• Check solution flow to pad driver/brush head. Inspect
and clean solution filter assembly.
• Flush solution tank and hoses with a mixture of 8 oz/250
ml white vinager to 1 gal/4 l water.
• Repair or replace any worn or damaged components as
needed.

Monthly Maintenance

• Verify all daily and weekly maintenance has been
performed.
• Grease the caster axle and swivel bearing. Use only
water resistant lithium-based 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.
• Check return handle springs of the twist grip handles. If
they appear weak or do not return
the grips to the neutral position, replace both springs as
needed.
Mandatory Periodic Maintenance
It is important for you to maintain a record of the amount
of machine operating hours in order to perform this
machine maintenance. It is mandatory that the following
maintenance procedure be performed at the described
interval. This procedure should be performed by an NSS
service center. Failure to perform this procedure may
result in poor machine performance, machine component
damage and failure.
• After every 450-500 hours of operation: Inspect vac
motor carbon brushes for wear.
• After every 650-700 hours of operation: Inspect drive
motor (transaxle) carbon brushes for wear. Inspect
brush drive motor carbon brushes for wear.
• Replace the drive motor (transaxle) carbon brushes
when they are 3/8 in. (9 mm) in length.
• Replace the brush motor carbon brushes when they are
1/2 in. (13 mm) in length.
• Replace the vacuum motor carbon brushes when they
are 7/16 in. (11 mm) in length.
Authorized Repair Service
Repair service for this machine must be performed by an
NSS authorized service center. Repairs not performed
by an unauthorized company will void the machine
warranty. If you require assistance finding an authorized
service center, contact NSS Enterprises.
