IMPORTANT SAFETY INSTRUCTIONS
GROUNDING OF ELECTRICAL EQUIPMENT
WARNING: Improper connection of the equipment–grounding
conductor can result in a risk of electric shock. Check with a qualified
electrician or service person if you are in doubt as to whether the outlet
is properly grounded. Do not modify the plug provided with the machine
– if it will not fit the outlet; have a proper outlet installed by a qualified
electrician.
Always use a properly grounded 3-wire extension cord, which has
male and female plugs. If 25 foot extension cords are used, the
electrical carrying capacity should be no less than 14-3 ST. 50-foot
extension cords no less than 12-3 ST.
GROUNDING INSTRUCTIONS
This machine shall be grounded while in use to protect the operator from electric shock. The machine is provided
with a three-conductor cord and a three-contact grounding type attachment plug. The plug must be plugged into
an appropriate outlet that is properly installed and grounded in accordance with all local codes and ordinances.
The green conductor in the cord is the ground wire. Never connect this wire to other than the grounding pin of the
attachment plug.
Check nameplate on the machine to be sure voltage and cycle stated is the same as the electrical outlet. Do not
attempt to plug a 120 volt machine into a 240 volt outlet or a 240 volt machine into a 120 volt outlet. If the
machine is provided with an attachment plug as shown in Figure A. below, it is intended for use on a nominal 120
volt circuit. If a properly grounded receptacle as shown in Figure A. is not available, an adapter may be installed
as shown in Figure B. if the outlet box that houses the receptacle is grounded. Be sure to fasten the grounding tab
(the green colored rigid ear, lug or the like extending from the adapter) with a metal faceplate screw.
If the machine is provided with an attachment plug as shown in Figure C., it is intended for use on a nominal 240-
volt circuit. No adapter is available for this plug.
NOTE: In Canada, the use of a temporary adaptor is not permitted by Canadian electrical code.
ALL REPAIR SERVICE MUST BE PERFORMED BY AN NSS AUTHORIZED DISTRIBUTOR/
SERVICE STATION USING ONLY NSS ORIGINAL EQUIPMENT PARTS.

• To assemble the machine, simply remove the two
sections from their cartons, and perform three (3) easy
steps:
A tank for dispensing solution for cleaning bare
floors or for dispensing shampoo for carpet
scrubbing is available (see the accessories page
included in the Illustrated Parts List for details).
Assembly instructions for this accessory are
included with the tank.
Once assembled attach the pad or brush, unwrap
the cord from the handle, plug in the machine, you
are now ready to operate the machine.
2. Tip the machine back on to the handle. Insert
the washers and bolts as shown. Leave the
bolts finger tight until all have been started, then
Tighten.

OPERATION
Preparing the Machine for Use
• With the handle locked in the upright position, tilt the
machine back, exposing the underside of the machine.
• Attach the brush or pad driver to the lugs on the
gearbox by rotating the pad driver or brush
counterclockwise.
• To adjust the handle position, put the machine into an
upright position, resting the pad or brush on the floor.
Lift the handle lock to allow the handle to move freely.
Adjust the handle to a comfortable operating position
(just below belt height), and then push the locking
lever down to lock the handle in this position. Should
the lock lever not tighten securely to the handle tube,
see “Lock Lever Adjustment” in the Maintenance
section of this manual.
• Always check to see that the dead man or switch lever
lockout located at the top and center of the handle is in
the “OFF” (up) position and not stuck or
malfunctioning in the “ON” (down) position before
plugging in machine.
• Remove all of the cord from the handle and cord hook,
plug the cord into the wall outlet.
Running the Machine
• To start the machine, grip the handles with both hands
and raise the handle slightly to balance the machine.
Then push down on the lock-out with the thumb of one
hand, and with the other hand squeeze the switch
lever.
CAUTION: The machine will start operating when the
switch lever is squeezed.
• Raise the handle slightly to propel the machine to the
right, Lower the handle slightly to propel the machine
to the left.
• Begin operating the machine at a point closest to an
electrical outlet, then working away from the outlet.
This will prevent running over the electrical cord.
Stopping the Machine
• WITHOUT LETTING GO OF THE HANDLE, release
the switch levers to stop the machine.
CAUTION: This machine will continue to rotate for 1-2
seconds once the switch levers are released. When
the machine comes to a complete stop, UNPLUG THE
MACHINE.
• Release the handle lock, raise the handle to an upright
position, and lock the handle.
• Tilt the machine back and remove the pad driver or
brush by rotating it clockwise.
• ALWAYS remove the pad driver or brush when the
machine is not in operation. The pad driver or brush
should be hung on a peg, or laid flat on its back.
• NEVER store a pad driver or brush with the bristles
down. This will ruin the balance of the pad driver or
brush, which will cause the machine to wobble.
SURFACE CONCIDERATIONS
Brush or Pad Driver
Select the appropriate brush or pad driver and pad
for the type of floor to be scrubbed or polished, and
the operation being performed.
Carpet
When scrubbing carpeting with a brush, pad or
bonnet mop, the carpet must stay wet enough to
lubricate the brush, pad, or bonnet mop, otherwise
overload of the motor will result.
Overload
Attention must be given to ensure the motor is not
run in an overload condition.
• 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:
• Too much weight. Do not add weight to this
machine.
• The floor is not wet enough.
• Too much spray buff.
• Incorrect brush or pad size is.
• Pad is too worn and needs to be changed.
• Too high or too low voltage (the voltage must
be ± 10% of the rating on the nameplate).
• Use of too long, too small of gage, 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 front page 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.
• If the machine is equipped with a handle mounted
solution tank, empty the tank and rinse.
• 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:
• 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.
