WARNING:
To reduce the risk of fire, electric shock or injury:
When using an electric burnisher, basic precautions should
always be following, including the following:
1) DO NOT leave burnisher plugged in
when not in use. Unplug from outlet when
not in use and before servicing.
2) Electric shock could occur if exposed to
rain. Store indoors.
3) This is NOT a toy. Close attention is necessary when used around or near children.
4) Use only as described in this manual.
Use only manufacturer's recommended
attachments.
5) DO NOT use with damaged cord plug.
When burnisher is not working as it should
because it has been dropped, damaged,
left outdoors, or dropped into water, contact the manufacturer or authorized service center.
6) DO NOT pull or carry by the cord, use
power cord as a handle, close a door on
cord, or pull cord around sharp edges or
corners. DO NOT run burnisher over cord.
Keep cord away from heated surfaces.
7) DO NOT handle the burnisher plug with
wet hands.
8) DO NOT unplug by pulling on the cord.
To unplug, grasp the plug, not the power
cord.
9) DO NOT put any objects into motor
openings.
10) Keep hair, loose clothing, fingers and
all parts of body away from moving parts.
11) DO NOT operate where oxygen or
anesthetics are used.
12) DO NOT use around flammable or combustible liquids such as gasoline or use in
areas where they may be present.
13) DO NOT use an extension cord unless
absolutely necessary. If an extension cord
is used, then wire size must be #14 gauge
or thicker and should not exceed 50 feet in
length. Extension cord must be three-wire
type to insure grounding protection.
14) Replace damaged or worn parts
immediately with genuine original equipment parts to maintain safety and to protect your limited warranty.
GROUNDING
SAFETY
NSTRUCTIONS
I
DANGER:
Improper use of the grounding plug can result in a risk
of electric shock.
This burnisher must be grounded. If it
should malfunction or breakdown, grounding provides a path of least resistance for
electrical current to reduce the risk of electric shock. The burnisher is equipped with
a cord having an equipment-grounded plug.
The plug must be inserted into an appropriate outlet that is properly installed and
grounded in accordance with all local
codes and ordinances
PAGE 2
If repair or replacement of the cord or plug
is necessary, DO NOT connect the grounding wire to either flat blade terminal. The
wire with insulation having an outer surface
that is green with or without yellow stripes
is the grounding wire.
GROUNDING
METHODS
This burnisher is for use on a nominal 120
volt circuit, and has a grounding plug that
looks like the plug illustrated in (Fig A). A temporary adaptor that looks like the adaptor
illustrated in (Fig B & C) may be used to connect the plug to a 2-pole receptacle as
shown in (Fig A) if a properly grounded outlet
is not available.
The temporary adaptor should be used only
until a properly grounded outlet (Fig A)can be
installed by a qualified electrician. The green
color rigid ear, lug, or the like extending from
the adaptor must be connected to a permanent ground such as a properly grounded
outlet box cover. Whenever the adaptor is
used, it must be held in place by the metal
screw (Fig C).
WARNING:
Improper connection of the equipment-grounding conductor can result in a risk of
electrical 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 burnisher. If it will not fit the
outlet, have a proper outlet installed by a qualified electrician.
WARNING:
To avoid fire, DO NO use with a flammable or combustible
liquid to clean a floor.
This burnisher can be used in conjunction
with any of the ultra high speed chemical systems. It is mandatory, however, that the floor
be prepared as directed by the chemical
manufacturer. This will eliminate a possibility
of damage to floor due to the burnishers high
speed.
The burnisher is pre-set at the factory for
use with a 1" thick buffing pad
The rougher hair surface is preferred for
high luster floor finishing.
1. Before operating this burnisher, check to
see that the buffing pad is properly centered
on driver and that center pad lock is tight on
pad.
2. When operating the burnisher it MUST
be kept moving, as holding machine stationary while running will result in damage to
floor and floor finish.
(1 shpd w/unit).
3. Begin operating the burnisher at the closest point to your electrical outlet and work
away from the outlet. This will prevent running over the electric cord.
4. Never leave burnisher resting on buffing
pad for an extended period of time. This will
cause buffing pad to lose its normal shape,
causing wobbling or vibration and pad must
be replaced. Also, replace pad if glazed,
clogged, torn or shredded.
5. The rear wheels on the 1500 RPM and
2000 RPM burnishers are factory-set for
low amp rating and high luster burnishing
with buffing pad. See instruction sheet.
6. A carbon brush wear indicator warning
light is located on the motor canopy. When
lit, motor carbon brushes must be replaced
within 20 hours running time to prevent
damage to motor. See instruction sheet.
NOTE:
In Canada, the use of a
temporary adaptor is not
permitted by the
Canadian Electrical Code.

OPERATING
INSTRUCTIONS
This unit is intended for commercial use.
OPERATION INSTRUCTIONS
Begin operating this burnisher at the
closest point to your electrical outlet,
working away from the outlet. This will
prevent running over the electric cord.
Operate the burnisher in a straight-line
path and avoid continuous operation in
one spot.
If burnisher wobbles, vibrates or pulls,
follow these instructions:
1) Never leave burnisher resting on floor
pad overnight. This will cause the pad to
lose its normal shape, causing wobbling
and vibration. Check pad for unevenness
and change is necessary.
2) Before turning burnisher on, run tip
of finger between outside of pad and
floor. The outer ring face should be in
full contact with the floor in order for
high speed buffing to be most effective.
If necessary change pad.
3) If necessary adjust front and rear
wheels:
Pad pressure becomes more critical
with a 2000 RPM burnisher. If excessive current draw is permitted, either a
blown circuit breaker or motor damage
will occur.
Front Caster Adjustment:
1) To increase pad pressure as well as
amperage draw "Lower" front caster
adjustment.
2) To reduce the pad pressure as well
as amperage draw "Raise" front caster
adjustment.
Proper pad adjustment is best achieved
by lowering front caster until the warning light located in the switch box activates. Then raise the front caster slowly until the warning light shuts OFF.
The rear wheels are adjusted and
locked in place at the factory to assure
proper alignment. The pre-set adjustment is based on the floor pad supplied
with this burnisher. To adjust for normal
pad wear follow instructions for Front
Caster Adjustment.
The rear wheel position should ONLY be
reset by a certified technician. To reset
rear wheels:
1) Attach floor pad.
2) Unlock rear wheel set screw using a
3/32" allen wrench and "Raise" all
three adjustment knobs until the buffing
pad is positioned 5/8" off the floor,
around the pad perimeter.
3) Lock rear wheel set screws.
4) It may be necessary to adjust pad
pressure. Follow the Front Caster
Adjustment Instructions.
First Warning System is located on the
control box face. When the red warning
light comes ON do the following.
1) Raise front knob slowly until light is
OUT. If the light fails to go OUT, see step
2.
2) Turn pad over or install a clean pad.
Second Warning System is a carbon
brush wear indicator light located on the
motor canopy. Instructions read a follows:
When lamp is lit, Motor Carbon Brush
MUST be replaced within 20 hours of
service to prevent damage to the motor.
Carbon Brushes Part Nos:
Imperial Motor: Part No 386790 (4)
Ohio Motor*: Part No 380083 (3) &
316954 (1)
Burnishers with Ohio Motors have "X" after
*
the serial number.
Note: After replacing the second set of carbon brushes, the commutator of the armature
may need to be undercut and the mica slotted.
This should be done by an experienced motor
repair shop.
