IMPORTANT SAFETY INSTRUCTIONS
CAUTION: Operators must read and understand this manual before operating or
maintaining this machine.
Keep hands and feet clear of moving parts while machine is in operation.
Disconnect the power to the machine by pressing the Red Emergency Disconnect Button
when charging batteries or during installation or removal of pads.
During operation, loose objects on the floor can become dangerous projectiles if struck by
the high speed pad. Special attention should be paid in removing or avoiding loose floor
tile, electrical cables, telephone connection boxes.
Electrical motors and components can cause an explosion when operated near explosive
materials Or vapors. Do not operate this machine near flammable materials such as
solvents, thinners, fuels, grain dust, etc.
Keep machine moving to reduce the risk of damaging floor finish and floor.
Make sure the Red Emergency Disconnect Button is pressed and the battery connector is
unplugged from the machine before performing any maintenance procedures.
Store or park this machine on a level surface only.
These machines are designed for level floor operation only. Do not operate on ramps or
inclines.
Battery acid can cause burns. When working on or around batteries, wear protective
clothing and safety glasses. Remove metal jewelry. Do not lay tools or metal objects on
top of batteries.
Charging batteries generates explosive gases. DO NOT CHARGE BATTERIES WHEN
OPEN FLAMES OR SPARKS ARE PRESENT. DO NOT SMOKE. Make sure the charger
is turned off before disconnecting it from the machine. Charge the batteries in a well-
ventilated area with the battery cover removed completely.
Maintenance and repairs must be performed by authorized personnel.

OPERATING INSTRUCTIONS
INSPECTION
Carefully unpack and inspect your burnisher for shipping damage. Each unit is tested and
thoroughly inspected before shipment; any damage is the responsibility of the delivery
carrier who should be notified immediately.
ELECTRICAL
This machine is battery operated and designed to operate on 36 volts DC (3) 12 volt
batteries.
BATTERIES
Burnishers are shipped with batteries. (3 required)
Part No. 956210 12V 210AH 20 Hr. Rate
We do not recommend mixing AMP hour capacities. Any alternate battery sets can be
used if they equal physical size and capacity. See next page for service and installation.
OPERATION
Before starting, familiarize yourself with the machine and its controls (see “Machine
Overview” and “Dashboard Control Panel” diagrams). To turn the machine ON, do the
following:
1. Make sure 20” high speed pad is used. Make sure the pad is installed on the
machine by following instructions under ”Pad Installation.”
2. Make sure that no battery charger is plugged into the recharge port.
3. Lift the red emergency disconnect button so it is in the up position.
4. Lower the pad driver assembly by pushing the pedal slightly outward on the
machine (unlock it), and then release it slowly.
5. Turn the key switch to the ON position. The pad driver will then slowly adjust itself
to the floor. Make sure the machine is set to move forward indicated by the light on
the dashboard control panel.
6. Place hands on the bails and squeeze the bail levers to start the operation of the
machine. Move forward in a straight line, check the reading on the Operating
Range Meter and make sure you are in the Green Zone.
7. Adjust the pad pressure as needed by turning the knob accordingly. (See Pad
Pressure Adjustments.)
8. Adjust speed as needed by turning the speed control knob accordingly.
5

AFTER USE
To raise the pad driver, push down until the pedal arm engages into the pedal catch. Turn
machine off by turning the key switch on the control panel. Machine can be cleaned with a
mild detergent and a damp cloth. Batteries should be charged after each use or when the
battery condition meter shows a low charge. Once the battery charger reads 0 amps, the
batteries are recharged. This should take approximately 8 hours if the batteries are
completely discharged.
MAINTENANCE
Periodically remove batteries from machine. Clean the batteries and battery tray with a
solution of baking soda and water. Check all battery cables and wiring for signs of damage
and wear. Replace as needed. Grease front wheel and rear caster zerks once a month for
best operation.
FLOOR SEAL STRIP
When the floor seal strip show signs of excessive wear, seal should be replaced. The strip
can be removed by loosening the screw on the retainer strap until the seal can slide off of
the pad shroud housing. To install new seal, slip the retainer strap over the new seal strip
and pad shroud. Make sure the seal is seated equally around the perimeter and the holes
on the floor seal are oriented towards the back portion of the shroud.
BATTERY SERVICE AND INSTALLATION
WARNING: Battery acid can cause burns. When working on or around batteries, wear
protective clothing and safety glasses. Remove metal jewelry. Do not lay tools or metal
objects on top of batteries.
CHARGING OF BATTERIES
Charging batteries generates explosive gasses. DO NOT CHARGE BATTERIES WHEN
OPEN FLAMES OR SPARKS ARE PRESENT. DO NOT SMOKE. Make sure the charger
is turned off before disconnecting it from the batteries. Charge the batteries in a well-
ventilated area with battery cover removed completely. Fluid levels should be checked
before and after charging and maintained at the proper levels. If the burnisher is not used
for extended periods of time, batteries should be kept fully charged with a boost charge
once a week.
6

PAD INSTALLATION
The red emergency disconnect button and the key switch must be in the OFF position
before installation and the pad driver assembly in the RAISED position. Remove center
cup locking device by gripping on outer edges and turning clockwise. NOTE: Center cup
cannot be pulled out; it must be unscrewed. After removing used pad, place new pad on
pad driver assembly using outer flange of pad driver to center the pad. Push centering
locking cup through the pad and into the pad driver assembly. The ratchet teeth on the
center cup will engage into the pad driver assembly and should be pushed in as far as
possible. If further tightening is needed, rotate the center-locking cup counter-clockwise.
PAD PRESSURE ADJUSTMENTS
The pad pressure adjust knob is located on the top of the control console. Counter-
clockwise rotation increases pad pressure, the opposite rotation decreases. Different
floors, conditions, and pads produce carrying pad load conditions. Ideal burnishing
conditions are maintained while the operating range meter remains in the Green Zone. If
the meter reads in the Red Zone decrease the pad pressure. When the machine is
operated in the Red Zone for a long period of time motor overload will occur and the 70-
amp circuit breaker for the motor will trip. If the motor circuit trips:
1. Check pad condition.
2. Decrease pad pressure.
3. Reset circuit breaker.
7

CIRCUIT BREAKER PROTECTION
70 amp circuit breaker protects pad driver motor from excessive overload conditions. 30
amp circuit breaker protects control circuits against possible electrical shorts. If either
circuit breaker trips, first determine the cause and correct the condition before resetting
the breakers.
CARBON BRUSH REPLACEMENT
Design life of carbon brushes is between 1800-2000 hours. Replace brushes if worn to
3/8" or less, broken, or chipped. All carbon brushes should be replaced when motor is
serviced. Four (4) are required, P/N 572003. Red indicator on control panel (above
Emergency Disconnect Button, below the Dashboard) will glow when carbon brush
service is required.
CARBON BRUSH SERVICE
1. Disconnect batteries from machine.
2. Remove two screws that hold dust control housing and motor cover to motor.
3. Blow out top of motor with air line.
4. Loosen screw and remove carbon brush lead.
5. Slide brush spring off the back of carbon brush and remove brush.
6. Reverse order for installation of new carbon brushes.
