Carbon Monoxide Poisoning Symptoms
Train your employees to know the warning signs of carbon monoxide poisoning.
Mild carbon monoxide poisoning may cause any of the following:
Headache, drowsiness, faintness, poor coordination, nausea, and vomiting.
Turn the engine off and immediately get to fresh air if you have any of these symptoms.
Do not run the machine until it is given an emissions test and repairs made by an authorized distributor.
Local emissions testing is available at a fork-lift service department.
Moderate or severe carbon monoxide poisoning causes confusion, unconsciousness, chest pain, shortness of breath, and
coma. Thus, most victims are not able to move themselves and must be rescued. Severe poisoning is often fatal.
Carbon monoxide is dangerous because a person may not recognize drowsiness as a symptom of poisoning. Consequently,
someone with mild poisoning can go to sleep and continue to breathe the carbon monoxide until severe poisoning or death
occurs. Some people with long-standing, mild carbon monoxide poisoning caused by furnaces or
heaters may mistake their symptoms for other conditions, such as the flu or other viral infections.
Carbon Monoxide Detectors
CO detectors are a must for safe operation of your equipment. Various types are available. A “CO” carbon monoxide detector
detects carbon monoxide before it reaches dangerous levels. Detectors are a must for those who run propane powered
equipment. The CO Detector is for everyone’s protection against Carbon Monoxide Poisoning.
• Carbon Monoxide Detector - Passive
– Effective for 30 days after package has been opened.
– Write the date opened on the detector.
– Mount with self-adhesive strip on the machine handle.
– Train machine operator to check detector regularly.
– If the orange disk changes to gray or black - your Carbon Monoxide Levels are
at a Dangerous Level.
– If the orange disk changes to gray or black you must turn your buffer off immediately and return it to your nearest
authorized distributor for an emissions test.
– Do Not Restart the machine until the emissions have been checked and corrected.
– This is for your protection as well as your customers. CO detectors are a must for safe operation and maximum
efficiency of your equipment.
– For replacement CO detectors, contact your distributor. Ask for the carbon monoxide detector,
part# E12426.
• Carbon Monoxide Detector - battery operated with alarm
– Available from various sources

SAFETY
lmportant Safety Information
All LPG (Liquid Propane Gas) powered engines, including this engine, produce Carbon Monoxide (CO). It is a
Lethal Poison that is colorless, odorless, tasteless, and non-irritating gas. You must read “Danger: Lethal Exhaust Gas”
information below.
Keep hands, feet, and loose clothing away from all moving parts while the machine is in operation. The exhaust system
gets very hot so keep hands, clothing and any items that can burn away from the engine, engine manifold, and muffler.
These machines are tough and durable, however do not abuse the machine. With proper care and maintenance this unit
will give you years of trouble free operation.
Carbon Monoxide Safety Information
Engine exhaust gases contain poisonous carbon monoxide. Carbon monoxide is odorless, colorless, tasteless, and
can cause death if inhaled. Failure to provide proper venting of CO, failure to properly maintain the engine, or failure to
properly train personnel of the dangers and warning signs of carbon monoxide exposure may result in Serious Injury Or
Death to the operator and others in the area.
Any equipment with the potential to produce carbon monoxide presents a significant hazard when used indoors.
They must be used with great caution. Opening a door or window, or running an exhaust fan will not necessarily
supply adequate ventilation. Avoid inhaling exhaust fumes and never run the engine in a closed building or
confined area without proper ventilation.
Do not allow engine to run unattended.
If you have any indication that the engine is not running properly, immediately shut the machine off and have it
checked over and repaired by qualified maintenance personnel.
Workers should be trained to recognize the hazards of carbon monoxide and the early symptoms of carbon
monoxide poisoning.
A carbon monoxide detector and alarm should be available to alert workers of emissions.
Have a carbon monoxide detector attached to machine handle or have machine operator wear a carbon monoxide
detector. (See carbon monoxide detector page).
Use only as described in this manual.
Use only manufacturer’s recommended components.
Maintenance and repairs must be done by qualified personnel.
Only trained operators should be allowed to operate propane powered floor machines.
If the machine is not working properly, have it serviced by an authorized service center.
Install fuel cylinder in a well ventilated place.
Be aware of possible leaks of propane gas if odor is present.
If the machine is stored inside a building, remove the fuel cylinder and store properly outside.
Secure fuel cylinders when being transported.
If tank is left attached to the machine then valve should be OFF.
Never store fuel cylinders in a vehicle, building, or area where they may exposed to high temperature.
Do not operate the machine with any openings blocked.
Keep openings free of debris that may reduce airflow.
Remove fuel cylinder and disconnect battery before servicing.

TANK USE AND STORAGE
Propane Tank Use
We use the Worthington gas cylinders designed for vapor withdrawal. The fuel lock offs, regulators, and engines are
also designed for vapor withdrawal.
We recommend that you use the OPD (Overflow Protection Device) vapor withdrawal type cylinder. These style
tanks have a triangle shaped valve handle.
Do not overfill - the best gauge is a scale - never allow tank to weigh over 36 pounds for an aluminum tank and
43 pounds for a steel tank.
Connect fuel cylinder to machine in a well ventilated place.
Be aware of possible leaks of propane gas if odor is present.
Use propane tanks designed for vertical use only.
Propane Tank Storage
Store tanks outside in a well-ventilated area.
Never store fuel cylinders in a vehicle, building, or area where they may exposed to high temperature.
If the machine is stored inside a building, remove the fuel cylinder and store properly outside.
Secure fuel cylinders when being transported.
If tank is left attached to the machine then valve should be OFF.
Store tanks in the upright position (valves up).
Be aware of possible leaks of propane gas if odor is present.
STARTING AND STOPPING
THE HONDA ENGINE
Starting The Honda Engine
The Honda engine is equipped with a 110 volt starter and a push button start.
Place propane tank into handle assembly and close propane tank strap clamp to secure tank.
Attach propane hose coupling and fully tighten.
Tilt machine back so that pad is off the floor.
Open propane tank valve (turn counterclockwise) and check for any leaks.
Plug cord into starter connection and plug into wall outlet.
Push and hold throttle cable in the "Choke" position.
Push the red start button and hold until engine starts. Do not crank for more than 20 seconds at one time.
Wait at least one minute between tries when cranking. See troubleshooting guide if the engine does not start
after several tries.
After engine starts, set throttle to a slow operating speed until the motor warms up. Engine speed may be
increased after 3 to 5 minutes.
Unplug the cord from the wall and the machine and return the cord to its storage position.
Check for frost on the regulator and fuel line. Frost will indicate that the machine is drawing liquid propane
from an overfilled or incorrect tank.
Stopping The Honda Engine
Turn propane tank valve to the closed position (turn clockwise) and allow the engine to continue running until
it runs out of fuel.

OPERATOR PREPARATION
Before Starting the Machine
Read the Owner’s Manual and the Engine Operation Manual.
Your machine is shipped ready for operation; however there is no fuel in the tank. When having the tank filled, you
must make sure the tank is never over-filled.
The best way to do this is to tell the filling station to weigh the tank full. On an aluminum tank, it should weigh
no more than 36 pounds and on a steel tank no more than 43 pounds. (See more information at “Tank Storage
and Maintenance” page.)
Adjust the handle for comfortable operation. Remove hairpin cotter pins from clevis pins, remove pins, and adjust to
the hole alignment that gives the most comfortable height. Replace clevis pins and hairpin cotter pins. Tighten nuts and
bolts if needed.
Make sure pad is not torn, pad is well attached and centering device is tightened.
Check Oil Level: Starting the engine without the proper amount of oil will cause severe engine damage. Always keep
the engine oil level between the full and add marks on the dipstick. Do not loosen oil fill cap or remove dipstick while
engine is running.
Park your burnisher on a level surface.
Turn the oil fill cap counter clockwise and then lift from the fill tube.
Wipe the dip stick clean and push it back into the oil fill tube until the cap seats and then withdraw it to check:
the oil level. (Do not screw cap on to check oil). Add if necessary. If the oil level is low, add API Class SM oil
having a SAE viscosity grade appropriate for the expected temperatures as indicated in the Operators Manual
(Usually a HD30 or 10W30).
Important Note: Do Not Overfill
Replace oil cap.
Inspect fuel hoses and fittings for wear and leaks. Have all worn hoses and leaks repaired before operating.
Look and listen for exhaust leaks. Have all leaks repaired before operating.
Check the carburetor filter and air filter for debris. Clean and replace if necessary.
Connect fuel hose to tank by screwing the hose fitting to tank. You must tighten all the way down to make fuel
connection. Turn tank knob slowly until you hear the flow of fuel into fuel system.
