•  DO NOT OPERATE ON STEPS.
•  PERIODICALLY INSPECT BATTERY.

 Only the manufacturer or an authorized servicing agent should replace the battery. Do not open or 

tamper with battery. Doing so voids all warranties and could cause injury due to electrical shock.

SPECIFIC GUIDELINES FOR SAFE OPERATION

Anyone operating the machine must read the following carefully in order to be informed of potentially dangerous operating conditions.  Opera-

tors should be familiar with the location and use of all safety devices on the machine.  Do not use the machine if it is not in proper operating 

condition, and report any damage or operation faults immediately. 

•  OPERATE THIS MACHINE IN A WELL-VENTILATED AREA.

 

It is the responsibility of the machine operator, machine owner, and the 

site manager to ensure that the air exchange system where the machine is to be used is in compliance with local building codes and is 

operating properly.  Failure to operate this machine in a  well-ventilated area could lead to sickness, injury, or death from carbon monoxide 

(CO) exposure.

•  THIS MACHINE EMITS CO.

 CO is a colorless, odorless, non-irritating gas.  The first symptoms of CO exposure include headache, drowsi-

ness, dizziness, and nausea.  If you should experience any of these symptoms while operating the machine, shut off the machine and go 

outside to get fresh air.  Have the machine tested for CO emissions by a qualified service technician before using it again.

•  PROPANE IS A HIGHLY FLAMMABLE FUEL. 

If you smell propane, shut off the machine immediately and take it outside the building. Do 

not use the machine again until a qualified service technician has corrected the issue. 

•  DO NOT USE OR ALLOW ANOTHER PERSON TO USE AN IGNITION SOURCE NEAR THE MACHINE.

 Do not use cigarette lighters 

or smoke near the machine. 

•  DO NOT STORE OR VENT PROPANE CYLINDERS INSIDE A BUILDING.
•  THIS MACHINE HAS PARTS THAT CAN CAUSE SEVERE INJURY IF TOUCHED WHILE MOVING.  

Do not allow any part of the body 

or clothing to come in contact with these parts while they are moving.  Do not try to change attachments while the machine is running.  Do 

not allow other people to come near the machine while it is in operation.  Do not allow the machine to run unattended. Do not leave the ma-

chine in a place where unauthorized or untrained personnel could use the machine.  Do not run the machine with the pad off-center, dam-

aged, or missing.  Do not run the machine with unsecured guards and shields.  Do not operate the machine if the machine has loose parts.

Federal law and California State law prohibits the following acts or the causing thereof: (1) the removal or rendering inoperative by any person 
other than for purposes of maintenance, repair, or replacement, of any device or element of design incorporated into any new engine for the 
purpose of emission control prior to its sale or delivery to the ultimate purchaser or while it is in use, or (2) the use of the engine after such 
device or element of design has been removed or rendered inoperative by any person.

•  DO NOT TAMPER WITH THE ORIGINAL EMISSION-RELATED PART: t

hrottle body and internal parts, spark plugs, magneto or elec-

tronic ignition system, air cleaner elements, crankcase, cylinder heads, breather chamber and internal parts, intake pipe and tube, regula-
tor, fuel lock-off.

•  OVERFILLED OR LIQUID WITHDRAW CYLINDERS CAN DAMAGE THE FUEL SYSTEM AND CREATE A FIRE HAZARD.  

Do notover-

fill the cylinder or use a liquid withdraw cylinder on the machine.  If the regulator freezes, stop the burnisher and take the cylinder outside. 
Inspect cylinder; if it is a vapor withdraw cylinder, use gloves or pliers to open bleeder valve and purge cylinder until only vapor is escaping.  
If it is a liquid withdraw cylinder, replace with a vapor withdraw cylinder.  

•  DO NOT MAKE UNAUTHORIZED MODIFICATIONS OR ALTERATIONS TO THIS MACHINE. 

 Modifications or alterations to this ma-

chine can lead to personal injury or damage to the machine. NFE assumes no liabilities for injury or damage resulting from an unauthorized 

modification or alteration to the machine.  Any unauthorized modification or alteration to this machine voids all warranties.   

•  DO NOT TOUCH THE MUFFLER OR ENGINE UNTIL THEY HAVE COOLED. 

The muffler and the engine become hot enough while the

DANGER:

 PROLONGED OR HIGH EXPOSURE TO CO MAY RESULT IN VOMITING, CONFUSION, AND COLLAPSE IN ADDITION TO 

LOSS OF CONSCIOUSNESS AND MUSCLE WEAKNESS.  IF SUCH SYMPTOMS OCCUR, CALL 911 FOR EMERGENCY MEDICAL AT-

TENTION.  IF YOU HAVE EXPERIENCED THESE SYMPTOMS, DO NOT OPERATE THIS MACHINE OR ANY OTHER PROPANE MACHINE 

AGAIN UNTIL CLEARED BY A PHYSICIAN.  EXCESSIVE EXPOSURE TO CO CAN RESULT IN DEATH.
