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
and 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.
Makesure theRed EmergencyDisconnect Buttonis pressedand thebattery connectorisunplugged
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. 956701 12V 165AH 20 Hr. Rate (Standard)
Part No. 956210 12V 210AH 20 Hr. Rate (Optional)
We do not recommend mixing AMPhour 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 power switch to the ON position. The pad driver will then slowly adjust itself to the floor. Move
forward in a straight line, check the reading on the Operating Range Meter and make sure you are in the
Green Zone.
6. Adjust the pad pressure as needed by turning the knob accordingly. (See Pad Pressure Adjustments.)
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.

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 rotationdecreases.Differentfloors,conditions,and pads produce carryingpadloadconditions.
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.
Circuit Breaker Protection
70 amp circuit breaker protects pad driver motor from excessive overload conditions. 3.0 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.
