This appliance must be grounded. If it should malfunction or breakdown, grounding provides
a path of least resistance for electric current to reduce the risk of electric shock. This machine
is equipped with a cord having an equipment -grounding conductor and grounding plug. The
plug must be inserted into an appropriate outlet that is properly installed and grounded in
accordance with all local codes and ordinances.
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 appliance - if
it will not fit the outlet, have a proper outlet installed by a qualified electrician.
This appliance is for use on a nominal 115-volt circuit, and has a grounding plug that looks like
the plug illustrated in sketch A.

UNCRATING
Your Powr-Flite Ultra High Speed Burnisher
was protectively packed to prevent damage
in shipment. We suggest that upon removing
the unit from its carton you carefully inspect
it for any possible damage in transit. If
damage is discovered, immediately notify the
transportation company who delivered your
machine. As a manufacturer, we are unable to
act upon any claim for concealed damage: you
must originate the claim.
IMPORTANT SAFEGUARDS
This machine is designed to be safe when
used to perform the functions specified in this
Operator’s Manual. Should damage occur to
electrical or mechanical parts, the machine
should be repaired by the manufacturer or
competent service center before using in order
to avoid further damage to the machine or
physical injury to the user. Your floor machine
is equipped with a safety switch lockout device
designed for your safety. Do not attempt to
bypass or defeat the safety lockout device.
Never use any device to lock the power switch
in the ON position.
Fig 1
APPLICATION
The NM2000 Ultra High Speed Burnisher is
used to achieve and /or maintain a high gloss
appearance on an established floor finish.
The high pad revolution of the floor burnisher
combined with a good polishing pad will turn
properly established cleaned floor finish into a
high gloss, hardened finish known as the ‘wet
look shine”. Recommended pads are beige or
white synthetic pads, or the natural hogs hair
blended pads.
Preparation of the Surface
Before each use of this machine, the floor
must be dust mopped with a treated mop and
if necessary clean the floor with a damp mop
using a solution of water and neutral cleaner.
PREPARE THE MACHINE FOR OPERATION
WARNING: To prevent injury, always remove
the electrical plug from the electrical outlet
before changing the polishing pad and before
leaving the machine.
With the handle locked, tip the machine back
until the handle is lying flat on the floor
To remove the pad-lock pad holder from the
flexible pad driver, grasp the center support
with your thumb and forefinger and turn the
collar counter-clockwise (see figure 1).
Place a clean or new 20” buffing pad over the
alignment ring on the pad holder
Replace the collar by turning clockwise until
snug (see figure 2).
Step back and tilt the burnisher to the upright
position.
Connect the power cord into a grounded, 3-wire
outlet.
The NM2000 Ultra High Speed Burnisher
should be operated with the handle in the
unlocked “floating” position to provide excellent
maneuverability and automatic pad contact.
The units are designed for maintenance of large,
open areas. To prevent excessive pad drag
or uneven burnishing where tight, repetitive
turns are necessary, lock the handle for manual
control of pad contact.
NOTE: The hardened steel cam release
lever does not require extreme tightening to
effectively hold the handle in position. Over-
tightening the cam release lever will shorten the
functional life of the lever (see figure 3).

HOW TO OPERATE THE MACHINE
Plug the machine in as directed and lower the
handle to the desired operating height. Push
the safety switch forward (see figure 4) and
squeeze the switch triggers beneath the handle
grips. This activates the motor and stars the
pad in operation. Each time your release the
triggers the safety switch will reset. You will
need to follow the direction above to restart the
machine. CAUTION: When leaving the machine
unattended, disconnect the wall plug and return
the handle to the “locked” upright position to
prevent accidental starting.
Push the machine forward in a straight line, at
a slow walking speed. Overlap each pass by
about 1 inch (25mm).

AFTER USING THE MACHINE
Upon completion, dust mop with treated mop to
pick up all burnishing residue.
The condition of the floor pad has a direct effect
on the performance of your burnisher. When
the pad becomes dirty, turn it over and use
the other side. When finished, wash the pad
out and allow it to dry completely before using
again.
TRANSPORTING THE MACHINE
Use the rear wheels for transporting the
NM2000 Ultra High Speed Burnisher. This will
insure that the operating wheels remain clean
and smooth for use on clean floor surfaces (see
figure 5).

MAINTENANCE
Once a month remove the motor cover of the
unplugged NM2000 Ultra High Speed Burnisher
by removing the motor cover screws.
Vacuum out any dust or debris which has
accumulated on the motor (see figure 6).
Replace the motor cover by setting it over
the holes in the housing and replace all of the
screws.
Check and maintain the tightness of all the
fasteners.
WARNING: Do not over-tighten the switch
housing screws.
Keep the burnisher clean, especially at the
handle tube and collar so the handle tube will
move freely through the collar.
Inspect the cord for cuts, gashes, or loose
prongs; replace as needed.
The length of the carbon brushes should be
inspected annually. If they are no longer
extended past the holder window, they should
be replaced.
Replacement of carbon brushes should be done
only by a qualified service technician.
Disassembly of this motor voids the warranty.
Improper disassembly and assembly of this
motor can permanently damage the field or
rotor.
