GROUNDING INSTRUCTIONS

Machine must be grounded. If it should malfunction or breakdown, grounding provides a path of least resistance for electrical current to reduce the risk of electrical shock. This machine is equipped with a cord having an equipment-grounding conductor and grounding plug. The plug must be plugged into an appropriate outlet that is properly installed in accordance with all local codes and ordinances. Do not remove ground pin; if missing, replace plug before use.‌‌​⁠​‌‌⁠⁠​⁠‌​‌‍⁠⁠‍‍‌​​​​​​‌​​​​‌​⁠​​⁠‌‍​​‍​‌‌​‍​‌‍​‌⁠​‌‍⁠‍‍⁠

1. The machine is shipped fully assembled. Pads are sold separately. Select and install a recommended pad that best meets your burnishing needs.

2. Pull the handle release lever and raise the handle to the upright position. Carefully tilt the machine backwards and rest the handle on the floor (Figure 1).

3. To install the pad, remove the plastic centerlock ring from the pad driver by turning it clockwise. Position the pad on the pad driver and replace centerlock ring by turning it counter-clockwise. Make sure the centerlock ring is fastened securely (Figure 2).

4. Return machine to the upright position.

MACHINE OPERATION

FOR SAFETY: Do not operate machine unless operator manual is read and understood.‌‌​⁠​‌‌⁠⁠​⁠‌​‌‍⁠⁠‍‍‌​​​​​​‌‍​​​‌​⁠​​​⁠‌⁠‌​⁠​⁠‌​‍‌​‌‍⁠​⁠⁠​‍⁠‌

1. Plug power supply cord to a grounded wall outlet (Figure 3).

This machine is not equipped with an explosion proof motor. The electric motor will spark upon start up and during operation which could cause a flash fire or explosion if machine is used in an area where flammable vapors/liquids or combustible dusts are present.

2. Release the handle from the upright position by lifting the handle release lever and lowering the handle (Figure 4).

3. Start machine by pressing the safety lock button and turning the twist grips forward. Release thumb from the safety lock button once machine starts (Figure 5).

ATTENTION: Use caution when starting out. Machine will jolt when twist grips are turned.

4. Begin burnishing by pushing the machine forward or using a "W" pattern motion.

FOR SAFETY: When using machine, stay clear of spinning pad.

SPRAY BUFFING INFORMATION: Spray buffing is only recommended with the BR-1200-NDC model. The BR-1600-NDC model should not be used for spray buffing; circuit breaker may trip or machine overloading may occur. The BR-1600-NDC model require more power at increased amp draw due to higher speeds.

SPRAY BUFFING INFORMATION:
This machine should not be used for spray buffing; circuit breaker may trip or machine overloading may occur.

5. To prevent the possibility of motor overload and causing circuit breaker to trip, periodically check pad for excessive soil build-up. Turn pad over, clean or replace when necessary.

6. To stop machine, rotate twist grips backward and safety lock button will engage.

7. Do not operate the machine in the same spot for a long period of time. Floor damage may result.
8. To maneuver over thresholds and floor grates, stop the machine and tilt it back on the transport wheels.
9. When machine is not in use, do not leave machine standing on the pad. Pad damage may result.
10. When done burnishing perform the following machine maintenance procedures.

MACHINE MAINTENANCE

1. Remove and clean the pad after each use.
2. Always store machine tilted back on rear wheels.
3. Clean the machine with an all purpose cleaner after each use.
4. Inspect the power cord for damage after each use. If worn or damaged, replace cord immediately.
5. Wipe the power cord with damp cloth and neatly coil it around cord hook and handle after each use.
6. Gear system and motor are factory lubricated and require no further attention.
7. Once a month, check the tension of the drive belt. At mid- point of belt, the belt tension should have a 1/4 in / 6.4 mm deflection at 5 lb of force (Figure 7). To tighten belt, remove the pad driver and loosen the (4) pad driver pulley bracket hex head screws. Loosen the jam nut on the tension bolt and turn bolt clockwise until belt is properly adjusted, then retighten the pulley bracket screws and jam nut (Figure 8).

8. Every 250 hours of operation, check the motor for carbon brush wear. Replace brushes when worn to a length of 3/8 in / 1 cm or less. Contact an Authorized Service Center for carbon brush inspection.

STORING MACHINE

1. Unplug the power cord and remove the pad from the machine. Neatly coil the cord around the cord hook and handle to prevent cord damage (Figure 9).

2. Store the machine in a dry area in the upright position with the handle positioned upward or folded down.

TRANSPORTING MACHINE

1. Unplug the power cord and remove the pad from the machine. Neatly coil the cord around the cord hook and handle to prevent cord damage.
2. Load the machine using a recommended loading ramp or carefully lift the machine with adequate assistance.

3. Secure machine with tie- down straps when transporting by vehicle.
