IMPORTANT SAFETY INSTRUCTIONS
To assure the safe operation of this machine, you must read and understand all warnings and instructions in this book. If you
do not understand, ask your supervisor.
READ ALL INSTRUCTIONS BEFORE USING THIS MACHINE
WARNING: To reduce the risk of fire, electric shock, or injury:
1. You must be trained to operate this machine. This machine is to be operated for its intended use only.
2. Do not operate this machine unless it is completely assembled.
3. Always use a three-wire electrical system connected to the electrical ground. For maximum protection against electrical
shock, use a circuit that is protected by a ground fault circuit interrupter. Consult your electrical contractor.
4. To prevent electric shock, always remove the electrical plug from the electrical outlet before doing any repairs or maintenance and when leaving the machine unattended.
5. To prevent electric shock, keep the machine surface dry. Do not subject to rain. Store the machine in a dry building area.
Clean the machine with a dry cloth only.
6. Machines can cause an explosion when near flammable materials and vapors. Do not use this machine with or near fuels,
grain dust, solvents, thinners, or other flammable materials. Do not use flammables to clean this machine.
7. A qualified or authorized person must do maintenance and repairs.
8. To prevent damage to the power cord, do not move this machine over the power cord. Always lift the power cord over the
machine. Do not pull or carry cord, use cord as a handle, close a door on cord, or pull cord around sharp edges or corners.
Keep cord away from heated surfaces.
9. Do not use with damaged cord or plug. If the machine is not working as it should, has been dropped, damaged, left
outdoors, or dropped into water, return it to a service center.
Grounding Instructions
This machine 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 machine - if it will not fit the outlet,
have a proper outlet installed by a qualified electrician.
This machine is for use on a nominal 120-volt circuit, and has a grounded
plug that looks like the plug illustrated in figure A. A temporary adapter that
looks like the adapter illustrated in figures B and C may be used to connect
this plug to a 2-pole receptacle as shown in figure B if a properly grounded
outlet is not available. The temporary adapter should be used only until a
properly grounded outlet (figure A) can be installed by a qualified electrician. The green colored rigid ear, lug, or the like extending from the adapter
must be connected to a permanent ground such as a properly grounded outlet
box cover. Whenever the adapter is used, it must be held in place by a metal
screw.
NOTE: In Canada, the use of a temporary adapter is not permitted by the
Canadian Electrical Code
EXTENSION CORDS
Use only three-wire 12/3 or larger gauge approved extension cords that have
three-prong grounding type plugs and three-pole receptacles that accept the
appliance’s plug. Replace or repair any damaged cords or plugs.
When servicing, refer to authorized person only. Use only identical replacement parts.
NOTE: Do not use adapters shown in figures B & C in Canada

OPERATING PROCEDURES
WARNING! For the safe operation of this machine follow the instructions given in this booklet and the training given by your supervisor. Failure to do so can result
in personal injury and/or damage to machine and property!
DO NOT OPERATE MACHINE IN AN EXPLOSIVE
ENVIRONMENT!
The models shown in this manual are intended for commercial use.
PREPARATION
To prepare the machine for operation, make sure it is of
correct voltage and properly assembled. If in doubt, ask
your supervisor.
Your new floor machine operates in a straight-line forward
motion, rather than the normal side to side motion of a
conventional single disc machine. Be prepared by having
your floor area cleared and ready for the fast action of a
burnisher.
Prepare the floor area by sweeping, dusting or mopping as
needed. Check the proper application recommendations
and procedures found on the label of your finish container.
IF IN DOUBT, CALL YOUR SUPERVISOR .
WARNING! NEVER USE THIS MACHINE WITH
FLAMMABLE OR EXPLOSIVE MATERIAL!
OPERATION
Set the machine upright onto the pad. Plug the machine’s
power cable into a properly grounded outlet (see Safety
Instructions). Next, release the handle locking knob and
allow the handle to lower into a comfortable position. Then
secure the handle locking knob. This will allow the operator to easily control the brush pressure.
Depress the handle slightly to elevate the pad from the floor.
This is to avoid burning the floor on initial start up, before
the operator is ready to move forward. Pull out on the
“Watch Dog” Safety Lock button and start the machine by
depressing either the left or right switch levers.
When you’re ready to move forward, lower the machine
head and pad to the floor and proceed forward in a straight
line, at a steady pace.
MAINTENANCE
AFTER EACH USE: Store the machine in a clean dry
area. Wipe the entire machine and cord down with a clean
cloth. Remove the pad and clean thoroughly. Wrap the
machine’s electrical cord onto the handles and the cord
hook provided. CHECK the cord and plug for nicks, cuts
or damage. Report these to your supervisor for correction.
WARNING! Always disconnect the machine’s electrical plug from the electrical outlet before performing any
service, maintenance, pad changing or inspection of the
machine.
For Burnishing: Select the correct clean floor pad (your
supplier can help you). The lighter color floor pads (buff or
white) are normally used for the burnishing procedure.
NEVER OPERATE THE MACHINE WITHOUT THE
FLOOR PAD INSTALLED!
It is very important to select clean, dry pads of uniform
thickness. Pads with high or low sections, or hard or soft
spots are unacceptable. Pads of open weave are recommended; because close weaves tend to load up fast, bog
down the machines, cause circuits to overload and generally give poor results.
Tip the machine back to expose the pad driver. Remove
the pad center lock ring. Carefully center the pad onto the
pad driver and secure with the locking ring. Check for
level, centering and flatness.
MOTOR: The motor is lubricated for life under normal
use. No oiling or greasing is necessary. However, if the
machine is used in dusty areas the motor should be cleaned.
Blowing the motor out with compressed air or with the
exhaust from a vacuum is suggested. Keeping the motor
clean will allow the clear passage of air for ventilation and
prevent overheating.
BELT TENSION: Proper belt tension is important for
smooth operation and belt life. Check the belt tension and
have no more than a 1/8-inch deflection. If adjustment is
needed, loosen the four (4) motor mounting bolts. Then
turn the belt tension adjustment screw (located at the rear
of the chassis) clockwise to tighten or counter-clockwise to
loosen the belt. Tighten the four (4) motor mounting bolts.
CARBON BRUSH INSPECTION: Long life 3000-hour
carbon brushes are installed in the motor. The machine is
also equipped with a carbon brush wear indicator light to
signal when a carbon brush change is required.
