1.1 Electric Power
This burnishing machine operates on a 15 amp
nominal 115V, 60 HZ, A.C. power circuit. (Motors
may be custom wired at the factory for 220 V, 50 Hz
international operation.) The amp, hertz, and voltage
ratings are listed on the motor spec label found on
each machine. Using voltages above or below those
indicated on the spec label will damage the motor.
Always check your local voltage requirements.
This burnisher must be grounded while in use to
protect the operator from electrical shock. This floor
machine is built with a 3-wire cord and a 3-prong
grounding type plug (Figure 1) to fit the properly
grounded receptacle.
Before using this floor machine, make sure a
properly grounded, 3-hole electrical outlet is
available. If not, as in some older facilities, use an
adapter for connecting a 3-prong plug to a 2-prong
receptacle (Figure 2) to ground to the outlet
chassis.
IMPORTANT!! This adaptor may not be used in Canada.
IMPORTANT!! Never cut off the grounding prong for use
in a 2-prong outlet. By doing so, you have cut off your
protection from electrical shock.
Never assume that all 3-hole outlets are properly grounded.
Never assume that an adaptor connection (as in Figure 2) is
properly grounded. Check the outlet with a ground fault
interrupter device which quickly indicates if a ground is
connected. Correct a faulty grounding before proceeding.
This floor machine is shipped with a 50 foot (15 M) long safety
cord which plugs directly into an approved outlet. The use of an
extension cord is not recommended.

(10) MERCURY ULTRA D.C. 1170 - 1500 - 2000 RPM MERCURY ULTRA D.C. 1170 - 1500 - 2000 RPM (3)

This high speed burnisher is shipped from the factory with the handle
unattached. You will need two 7/16” wrenches to complete the assembly.
Remove the handle and mounting hardware from its carton.
Bolts, nuts, washers and the locking lever assembly are in the
plastic bag attached to the handle.
1. Mount the handle on the chassis.
Align the handle with the yoke (1) over the
mount (2) on the burnisher chassis. The
power cord will be facing the motor. Place a
flat washer (4) on a 3” bolt (3), then place
the bolt through the holes in the yoke and
the mount. Place another washer on the
bolt and secure with the locking nut (5). Tip
the handle back and out of your way for the
next step.
2. Mount the support braces on the handle.
Tip the handle up. The handle mounting collar
(7) is designed to slide freely up and down the
handle tube, allowing the handle to be adjusted
for the comfortable operation of all users. Line up
the mounting collar with the upper holes in the
two straight handle braces (6).
!Place the curved spacer (12) with a
square hole onto the locking lever shaft
(11). The curve must face the lever.
!Insert the shaft through the upper hole in
the left handle brace (6), mounting collar
(7), and right handle brace.
!Place a spacer (9) on the shaft.
!Place the split washer (11) on the shaft
!Place the locking wing nut (13) on the
shaft.
!Adjust the wing nut for tightness. When
correctly installed, the collar slides easily
when the cam-engineered locking lever is
“up”, but is firmly fixed when the lever is
“down”.

2.1 Attach the Power Cord
The triple-wire grounded power cord has been factory-
installed into the handle tube. Plug the male connector (9)
coming out of the motor housing into the female connector
(10) coming out of the end of the handle tube.
Now, plug the end of the 50 foot long power cord into a
grounded power outlet. Release the safety lever, squeeze
the triggers on the handle and check for power
to the motor.
2.3 Inspect the Pad Driver
A flexible, high-speed pad driver has been bolted onto the burnishing
machine and dynamically balanced. This driver is the connection between
the burnisher and a disposable pad that burnishes the hard floor finish.
If this molded plastic part ever becomes damaged or if the molded hooks
are worn and cannot hold the pad, replace promptly.
Unplug the burnishing machine. Lock the handle in
the “up” position and tip the machine back fully.
Remove the 4 mounting screws (11) and
washers (12) from the drive hub (13).
Place the new pad driver (14) onto the main drive
pulley. Insert the mounting screws (11) and washer
into the bolt hole. Tighten securely.
2.4 Install the Pad
The face (bottom) of the pad driver (14) is covered with small “hooks”
that grab onto the pad (16). Every time you mount a new pad onto the pad
driver, follow these steps:
!Unplug the burnishing machine. Lock the handle in the “up” position and
tip the machine back fully.
!Mount the pad (16) over the male shoulder (15)
on the pad driver. Make sure that the pad is
centered on the driver.
!Insert the locking ring (17) through the center
hole in the pad and into the shoulder. Tighten
until the locking ring lies below the face of the
pad. If the ring is not fully locked, it will scratch
the floor.
Never operate the burnisher without a pad.
Never operate the burnisher with a damaged pad,
or without a locking ring to hold the pad in place.
Now, you’re ready to go to work!

3.0 Operating Tips
!For indoor use only.
!Sweep abrasive soils before burnishiung.
!While the pad driver is spinning, keep the burnisher moving to avoid “donut”
burns on the floor.
!To start operation:
- Unlock the handle by raising the locking lever.
- Lower the handle to a comfortable position, typically
waist height.
- Relock the handle by pushing the lever down.
NEVER OPERATE THE MACHINE WITH THE
HANDLE UNLOCKED.
- This burnisher has a high
torque motor. Hold the
machine firmly with both hands
when starting up.
- Push the red safety interlock
switch forward to unlock the
dual triggers.
- Squeeze both triggers to
send power to the motor. Once
power is on, either trigger will
keep power to the motor. To
stop, release both triggers.
3.1 To store your machine
!Lock the handle in the “up” position. Tilt the machine
back onto the transport wheels. Never store the machine
with the pad on the ground.
!Wind the cord around the handles and the bottom cord
hook.
!Wash pads and hang to dry.
!Inspect and maintain equipment on a regular
schedule for best results.
]Check and clean pads after each operation.
Remove soil and chemical buildup. Replace worn
or damaged pads.
]Check the triggers and switches for proper operation.
]Repair or replace damaged skirts and bumpers.
]Use air pressure or vacuum to remove dust
and debris from the motor vents.
]Report any performance problems and repair
promptly.
(6) MERCURY ULTRA D.C. 1170 - 1500 - 2000 RPM
To transport this machine from the janitor’s closet to the work area:
!Lock the handle in the “up” position. Wind the cord around the
handles and the bottom cord hook.
!Tip the machine back onto the transport wheels.
Push or pull the machine by the handle, not by
the cord or any other part of the machine.
Travel carefully.
4.0 Troubleshooting
Never operate this floor machine when the equipment is not performing as
expected or when any part is visibly damaged. The cause and solution for
some basic problems are described below. When repair is needed, take
the equipment to an authorized repair service center.
4.1 Floor machine will not run
- Circuit breaker tripped in building. Check and reset.
-Equipment unplugged. Check plug at wall and at machine base.
Plug in.
- Power cord failure. Test with a working power cord. Lock the
handle up and tip the motor back. Unplug the cord at the motor
and plug the motor into your working power cord.
IMPORTANT! THIS IS JUST FOR TESTING. When you do this, you
have removed the safety handle controls from the circuit and you
are sending power directly to the motor. If the motor now spins,
the problem is in the cord or the handle assembly. Seek
authorized repair service.
If the motor still does not spin, the problem is either in the male
connection at the motor base or in the motor. Seek authorized
repair service.
- Motor sparks or smokes. Seek authorized repair service.
4.2 Electrical shock to operator
-Equipment wiring failure or electrical short in the machine. Seek
authorized service.
- Poor grounding or no grounding. Test the outlet with a ground fault
interrupter. Retain a certified electrician to inspect and repair
grounding. NEVER clip off the ground plug on your cord.
- Repeated circuit breaking. High amp draw and circuit breaking can
be an electrical or mechanical problem. Seek authorized repair
service.
4.3 High Vibration
- Pad not centered. Tip machine back and re-center the pad.
- Unevenly wear or warp to pad or brushes. Replace.
- Machine chassis damaged by dropping. Replace.
