1.1 Electrical Power
This burnisher operates on a 13 amp nominal 115 V,
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 burnisher.
Using voltages above or below those indicated on the
spec label will damage the motor. Always check your
local voltage requirements.
1.2 Grounding Instructions
This burnisher must be grounded while in use to
protect the operator from electrical shock. This
machine is built with a 3-wire cord and a 3-prong
grounding-type plug (Figure 1) to t a properly
grounded receptacle.
Before using this burnisher, make sure a properly
grounded, 3-hole electrical outlet is available. If not
available, as in some older facilities, use an adapter
for connecting a 3-prong plug to a 2-prong receptacle
(Figure 2) to ground 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. Check before use.
Never assume that an adaptor connection (as in
Figure 2) is properly grounded. Check the outlet
with a ground fault interrupter device which quickly
indicated if a ground is connected. Correct a faulty
grounding before proceeding.
1.3 Extension Cords are Not Recommended
The burnisher is built with a 50 foot (15 M) safety cord which plugs directly into an
approved outlet. Use of any extension cords is NEVER RECOMMENDED.

1. Mount the handle to the chassis:
Align the handle with the yoke (1) over the mount
(2) on the burnisher chassis. The power cord will be
facing away fro the motor. Place a at 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 he 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.
• From behind the machine, insert the shaft
through the right handle brace (6), the
mounting collar (7) and the left handle brace.
• Place a spacer (9) on the shaft.
• Place the split washer (13) on the shaft.
• Place the locking wing nut (14) 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 rmly xed wen the lever is
“down.”
2.0 Mount the Handle
This 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.

2.1 Attach the Power Cord
The triple-wire grounded power cord has been factory-
installed into the handle tube. A exible rubber cable
connector (11) is used to secure the plug-in connections.
The burnisher ships with this connector mounted on the cord
coming out of the handle (10).
Stretch the connector and slip the male connector (9)
(coming out of the motor housing) through the connector
hole and then into the female connector. Now, plug the end
of the 50-foot cord into a grounded power outlet. Squeeze
the triggers on the handle and check for power to the motor.
2.2 Inspect the Pad Driver
A exible, 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 oor nish. 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) through the
washers (12) into the bolt hole. Tighten securely.
2.3 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.
• Pad Sizes: 20” diameter pad on the 20” and 21”
machines. Mount a 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 oor.
NEVER operate the burnisher without a pad.
NEVER operate the burnisher with a damaged pad of without a locking ring to hold the
pad in place.

3.2 Transport
To transport this burnisher 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 burnisher when the equipment is not performing as expected or
when any parts are 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 Burnisher will not Run
• Circuit breakers are tripped in the building. Check and reset.
• Equipment is unplugged. Check plug 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 of 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 certied 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
• Pads are not centered on the pad driver. Tip machine back and re-center the pad.
• Uneven wear or warp to pad or brushes. Replace.
• Machine chassis is damaged by dropping. Replace.
2.4 Adjust the Front Wheel Assembly on 2000 RPM Model
The 2000 RPM model is designed with a front wheel
assembly that controls the down pressure that the pad
applies to the oor. Raise the apron height to reduce the
down pressure. Lower the apron height as the pad wears.
The warranty on a 2000 RPM machine will be voided if the
machine is operated without this wheel assembly in place
and operating correctly.
3.0 Operating Tips
• For indoor use only. Sweep abrasive soils before burnishing.
• While the pad driver is spinning, keep the burnisher moving to
avoid “donut” burns on the oor.
To Start Operation:
• Unlock the handle by raising the locking lever.
• Lower the handle to a comfortable position, typically waist high.
• 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 rmly with both hands when starting up.
• Push the red safety interlock switch forward to unlock the dual
triggers.
• Squeeze both triggers to power 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.
• Use air pressure or vacuum to remove dust and debris
from the motor vents.
• Report problems and repair promptly.
