SAFE OPERATING PRACTICES (Continued)
Propane Powered Floor Burnishers are designed and manufactured for high speed commercial floor buffing only
These machines are designed to buff most modern types of floors including composition tile, stone, marble,
terrazzo, and resilient floor covering using floor coatings designed for high speed buffing
Even though NFPA 58 8-4 5 says " these machines shall be permitted to be used in buildings frequented by
the public, including the times when such buildings are occupied by the public " Nilfisk-Advance suggests
use when occupancy of a given work area is at a minimum
These machines should not:
• Be used in nursing homes, hospitals, day care centers etc
• Be used by unqualified or untrained personnel
• Be used unless properly maintained and adjusted
• Be left running unattended
• Be used on areas with obstructions such as thresholds, floor outlet boxes, etc
• Be used in rooms without proper ventilation
These Propane Powered Burnishers are designed with the burnishing head offset to the right side to make it
easier to burnish the floor close to the edge It is recommended to start burnishing on the right side of the aisle,
turn and come back down the isle in the opposite direction overlapping the previous path slightly Continue this
pattern until the floor area to be burnished has been covered with the last pass being on the right side of the
machine The forward speed is generally at a normal walking speed
Caution: Do not allow the burnisher to operate without moving. It ma burn the floor and could cause
damage to the floor covering.

I. Propane Machine Safet
A. Purpose
The accepted demand for and use of propane powered burnishers underscores the need
for responsible manufacturers and users to stress the importance of safet . This manual is
designed to provide the information ou need to ensure proper and safe use of propane
powered burnishers.
In addition, we recommend operators of propane powered burnishers to complete a
program of training and certification on the safe operation of this equipment.
B. Refueling and Storage of Fuel C linders
Propane cylinders should only be filled by an authorized propane dealer When not in use, they should
always be stored outside in an upright position in a secure, tamper-proof, steel mesh storage cabinet
This cabinet may be located next to the building but with at least five feet of space between the cabinet
and the nearest building opening (door or window)
The National Fire Protection Association (NFPA) Standard for Storage and Handling of LP Gas is the
appropriate U S A authority on safe propane use A copy of this publication is available through the
National Fire Protection Association in Quincy, Massachusetts (1-800-334-3555)
C. Safet in Engineering
Nilfisk-Advance engineers and manufactures machines utilizing U L (Underwriters Laboratories)
approved components where possible The U L logo will be affixed to a particular component This
means the component is listed Component recognition for the following parts is important: fuel
cylinders, couplings, regulators, and fuel lines We strongly recommend that you use only machines
meeting the above minimum requirements Even though the Kent propane powered burnishers meet
the O S H A Time Weighted Average (TWA) standard for noise, we still recommend hearing protection
be worn by the operator
D. Use and Care
Enclosed with our propane burnisher is a detailed Operator's Manual. Safet dictates that before
using an new equipment, read and understand the Operators Manual. We strongl recommend
this practice.
II. Machine Preparation
A. Adding Oil
The Burnisher is shipped by overland freight with the correct amount of oil in the engine Air freight
shipments require the machine to be shipped without oil
When Filling a "Dr " Burnisher or Changing The Oil:
Honda Engine: Add no more than 1 quart, then check the dipstick in the fill cap Add oil if
necessary but DO NOT OVERFILL! Always check oil before using the machine
NOTE: Honda engines use premium quality SAE 30, single viscosity motor oil
IMPORTANT: When checking oil, be sure that the machine is level Fill cap should be fully
screwed out and free Do not check oil by screwing cap in and then out again This will give a
false reading

II. Machine Preparation (continued)
B. Filling the Propane Fuel C linder
Nilfisk-Advance uses the 20 lb capacity aluminum fuel cylinder which meets the D O T 4E240
standards These cylinders are also listed by U L Filling should ONLY be done by a qualified propane
dealer A properly filled cylinder should not exceed 80% of the rated capacity
DO NOT attempt c linder repair. Return the c linder to our propane dealer if repair is necessar .
Please note that D.O.T. regulations prohibit shipping of c linders after the c linder has been filled
with propane.
C. Installing the Fuel C linder
Strap the cylinder in place by clamping the toggle assembly to the cylinder band Adjust the toggle
assembly by screwing in or out in order to keep the tank firmly secured Connect the fuel hose coupling
to the service valve by turning right (clockwise) HAND TIGHTEN ONLY. Make sure coupling is not
cross threaded and check for leakage by noting any odors of propane immediately after cylinder is
connected (It is sometimes easier to install if the connection to the service valve is made before
strapping the cylinder in place
To remove cylinder, reverse above procedure Always connect or change cylinders in a well ventilated
area
III. Operating Instruction
A. Starting Instructions
1 Check oil and fuel levels

III. Operating Instructions (continued)
C. Idling and Stopping the Machine
If for any reason the machine needs to idle for short periods of time, simply raise the burnishing head and
move the throttle to the SLOW position
Allowing the engine to idle excessivel will increase the concentration of carbon monoxide!
To stop the engine, close the service valve on the fuel cylinder by turning it clockwise (The engine will stop
when the fuel in the lines has been depleted)
NOTE: FOR EMERGENCY STOP: Pull throttle lever all the way back, this will activate the "KILL" switch
D. Installing/Changing Burnishing Pad
1 With engine OFF, turn the machine over on the RIGHT side (the starter side) This can easily be
accomplished by pushing down on the right handle grip with some force while the machine is tilted
back
2 Carefully pull old pad off the velcro pad holding material
3 Carefull inspect the padholder for cracks or damage. Replace if necessar .
NOTE: A damaged padholder rotating at high speeds may be an extreme hazard if it should come
apart
4 Pull center from new pad, center pad on padholder and tuck the center under the plastic center ring
5 Press pad onto velcro
6 Return machine to upright position
E. Storage
Only authorized, trained personnel should have access to propane cylinders and machines
1 Remove propane fuel c linder when not in use and store it outside in a storage cage in
accordance with NFPA Chapter 5-4.2.1. Do not release or bleed propane inside of building.
Please consult your local Fire Marshall to insure that you are in compliance with local fire codes
2 Store machine away from objects that may fall and damage it
3 Never store machine or fuel cylinders near an open flame or heat producing devices
4 Make sure machine is cleaned properly before storing
5 Never store machines with cylinders installed, or spare cylinders, in an enclosed van or trailer
F. Transportation
When transporting a propane powered burnisher with the fuel cylinder installed, the cylinder should be securely
fastened with the service valve closed and the machine should be secured in the vehicle Any
propane fuel cylinders not installed on a machine should be securely fastened to avoid movement and
damage The service valves should be closed Never store machines with cylinders installed, or spare
cylinders, in an enclosed van or trailer
It is good practice to check propane cylinders for overfilling before transporting them If overfilled, correct
before loading them in the vehicle by venting the excess propane outside in a safe area using the fixed liquid
level gauge
