WARNING: Keep the electrical parts of the machine dry. For storage, keep the machine in a building.
WARNING: Always use a three-wire electrical system connected to the electrical ground. For maximum protection against electric shock, use a circuit that is protected by a ground fault circuit interrupter. Consult with your electrical contractor. WARNING: To prevent damage to the power cord, do not let the pad, pad driver, or wheels touch the power cord when the machine is running. Always lift the power cord over the machine.

GROUNDING INSTRUCTIONS

This appliance must be grounded. If it should malfunction or break down, 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.

PROTECT THE ENVIRONMENT
Please dispose of packaging materials in an environmentally safe way according to local waste disposal regulations.
Always remember to recycle.

UNCRATING

Your Power-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.

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 the 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. Overtightening 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 a 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 it again.

TRANSPORTING THE MACHINE

Use the rear wheels for transporting the NM2000 Ultra High-Speed Burnisher. This will ensure 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 replacing 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.

Drive Belt Adjustment (see figure 7)

1. Remove the three (3) Phillips head screws holding the pad center grip
2. Remove four (4) large, slot head screws holding the drive pad.
3. Loosen pulley mount bolts (A) with a 9/16” deep socket wrench. Do not remove the bolts.
4. Using a 1/2” box wrench, turn adjustment nut (B) until it touches the adjustment bolt head. Turn the adjustment bolt to tighten or loosen the belt tension.
5. Correct belt tension allows belt (C) no more than 1/4” of side movement.
6. Tighten the four (4) pulley mount bolts with the 9/16” socket.
7. Loosen the adjusting bolt (D) until it is snug against adjustment stop molded in housing and turn adjustment nut against pulley mount bracket.
8. Replace pad driver and pad center grip.
