Cleaning Procedures
Spray Cleaning: Do not over use spray buffing or spray
cleaning. Many times, floors can be just polished to
achieve maximum results. Over-use of the spray buff
material and the failure to change pads when dirty can
limit the effectiveness. Spray clean only severely
marked, high traffic areas.
Restorers: Many floor treatments, when used as
directed, can clean, protect, and beautify tile floors.
When combined with a good foundation of finish and
regular maintenance, the luster can be maintained and
overall cleaning productivity improved. Floor treatment
is sprayed or mopped on and then buffed. All
treatments tested by NSS have responded best to high
speed buffing as compared to slower speed machines.
Damp Stripping: (Charger 1500 only) Wet or flood
stripping should never be performed with high-speed
machines, as uncontrolled splattering will result. Damp
stripping of smaller constricted areas, however, can be
performed quite successfully. Use a moderately
abrasive floor pad and a strong solution of neutral
cleaner or a weak solution of non-ammoniated stripper.
MAINTENANCE
Routine maintenance is critical to ensure proper
machine operation and cleaning performance. Perform
all maintenance procedures as follows:
Always unplug machine before performing any
maintenance. See front page for warnings.
Daily Maintenance
 Wipe off the entire machine with a clean cloth.
 Check the cord for any breaks in the wire. Breaks
would most likely occur near the plug and near the
handle. Also check the ground pin for breakage. If
any breaks are found, the cord should be replaced
immediately.
 Inspect the handle tube and handle clamp
mechanism for wear, damage, obstructions or any
build-up that may hinder easy movement of the
handle. If the handle will not move with the handle
lock in the up position, do not force movement.
Adjust as directed in the "Lock Lever Adjustment"
section or contact an NSS authorized service center.
 Check the dead man switch and throttle levers for
proper action.
Monthly Maintenance
 Lubricate the tube handle clamp area monthly with
a thin film of grease to allow ease of adjustment.
 Check the wheels for wear or damage. Replace if
needed.
 Apply a small amount of spray lubricant to the
axles. This will allow the wheels to roll freely.
 Check for loose bolts that hold the motor and
gearbox to the base of the machine. Tighten if
needed.
 Inspect the motor for accumulation of dirt in the
vents of the motor. If vents are blocked the motor
will over heat and fail. Clean out the dirt with a
vacuum or with forced air.
 Check the Lock Lever to ensure it securely locks to
the handle tube. If the clamp force is insufficient to
keep the handle from moving, perform the Lock
Lever Adjustment as follows:
 Loosen the two setscrews that hold the lock lever
bolt in position.
 With the lock lever in a horizontal position, tighten
the bolt counterclockwise until the bolt is snug
against the tube clamp.
 Tighten the setscrews and test the machine.
DO NOT OVER TIGHTEN.
Yearly Maintenance
 Disassemble the top of the motor to inspect the
brushes for wear. Brushes should be replaced
when they are worn to 3/8" [9.5mm] length, typically
after 1000 hours of use.
