Daily Maintenance; Monthly Maintenance; Yearly Maintenance - NSS Maverick 300 Instructions D'origine

 Listen to the motor when starting and during
operation. Within 1 - 2 seconds from starting the
sound of the motor will change as the motor
switches from "start winding" to "run winding".
 During operation if the sound of the motor
switches back to the "start winding" sound, this is
an indication that the motor has been overloaded.
STOP IMMEDIATELY.
 Check the machine over to find the source of the
overload and correct the problem.
 Overload may be caused by one or more of the
following:
o Too much weight.
o The floor is not wet enough.
o Too much spray buff.
o Incorrect brush or pad size.
o Pad is too worn and needs to be changed.
o Too high or too low voltage (the voltage must
be ± 10% of the rating on the nameplate).
o Use of too long, too small of gauge, or too
many extension cords.
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 page 2 for warnings.

Daily Maintenance

 Remove pad driver or brush from the machine.
Rinse and allow to air dry. Failure to remove the
pad driver or brush may cause damage to the pad
or brush, causing the machine to wobble or vibrate
excessively.
 Wipe off all of the plated and polished areas 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
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.
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
axle. 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:
Thoroughbred:
 Loosen the two set screws 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 set screws and test the machine.
DO NOT OVER TIGHTEN.
Mustangs / Mavericks
 Tighten the nut opposite side of the lever.

Yearly Maintenance

 Disassemble the top of the motor to inspect the
"stationary switch" for electrical pitting and
carbon build-up. Clean or replace stationary
switch as needed.
