SPECIFIC OPERATOR SAFETY INSTRUCTIONS
WARNING: the use of propane requires that specific safety precautions are
understood and followed for safe operation.
The following provides the basics of using propane gas. It is, however,
strongly recommended that employees or users who run Propane-powered
machines are properly trained on all aspects related to safety of the propane
use .
The employer must ensure his employees a certified training use of the
machine in order to ensure:
• information and training for the use of propane machine and devices;
• to make all users aware of propane equipment recommended standards of
the National Fire Protection Association (NFPA).
Training in the use of devices that use propane, refer to the local regulatory
authorities and with the requirements of NFPA 58, that can be consulted on
the website www.NFPA.org
DANGER: Propane is a flammable gas whose vapors are heavier than air.
As is the case with gasoline, propane can explode if the proper cautions are
not heeded. Propane is odorized with an agent having a distinct odor that is
recognizable at very low concentrations. This helps in identifying leaks, even
when they are small.
Awareness and basic safety precautions are required when working with
propane. As long as these precautions are followed, risk is negligible.
Ignorance, however, could pose needless risk.
The two greatest hazards with propane powered floor care machines are:
Carbon Monoxide Poisoning: This is the most frequently reported incident
associated with propane powered floor care machines and is caused by
excessive exhaust emissions. The symptoms are headache, dizziness and
nausea. A major cause involves engines with poor preventive maintenance
practices, usually those with dirty air filters and machines operated in confined
areas without adequate ventilation. Another cause may be substandard,
inexpensive machines with no emissions control technology and improperly
set carburetion.
Overfilled Fuel Cylinders: Nearly all fire related incidents reported result
from bringing a cylinder into a building without first checking for overfill. This
action is dangerous, unwise, and unnecessary.
Emissions
All propane powered floor care machines produceemissions. Most are
harmless, but some are dangerous and can be fatal. Carbon monoxide (CO)
poses the greatest risk, since CO can be lethal within as little as 30 minutes
exposure at 3,000 parts per million (ppm) concentration. Carbon monoxide is
an invisible, odorless, colorless gas created when fossil fuels (such as
gasoline, wood, coal, propane, oil and methane) burn incompletely. In the
home, heating and cooking equipment are possible sources are
possible sources of carbon monoxide. Vehicles running in an attached garage
could also produce dangerous levels of carbon monoxide. Any internal
combustion engine not maintained properly can also produce harmful levels
of CO.
work with this machine only and exclusively outside. It is the operator's and or
owner's responsibility, or the project supervisor to ensure this
requirement. Working in an closed area not well ventilated may cause illness,
injury or death by poisoning due to exposure to carbon monoxide (CO).
DANGER: these machines emit CO, which is a colorless, odorless gas. Early
symptoms of exposure to CO include headache, drowsiness, dizziness and
nausea. If any of these occur while operating the machine, switch off the
machine and go outside in the fresh air. Have the machine tested for CO
emissions by a specialist before using the machine again.
DANGER: high or prolonged exposure to CO can cause vomiting, confusion,
loss of consciousness and muscle weakness. If you
experience these symptoms, call the emergency medical assistance. If you
have experienced these symptoms, do not use the propane machine until
received medical care
and excluded possible CO poisoning. Excessive exposure to CO can cause
death.

Fire Safety
Be aware of the potential dangers of fire or explosion when using propane,
and take normal fire-safety precautions.
• Fire: There is a possibility of fire from LPG vapor
leaking or venting from fuel cylinders or carburetion equipment.
• Explosion: LPG vapor concentrated or confined to a small, restricted space
may explode or ignite.
• Propane may experience a BLEVE, a boiling liquid expanding vapor
explosion.
DANGER: propane is highly flammable and it has a slight health risk.
Because propane is odorized, it is easily detected at levels of just a few parts
per million, which is much less than the exposure limit of 1000 parts per
million.
If you smell propane (propane is odorized), do the following:
1. Stop the engine: turn the key switch to the off position. Do not
touch any electrical switches
2. Shut off the service valve on the propane cylinder.
3. Move the floor machine to a well-ventilated area.
4. Remove the cylinder from the machine and take it outside the building.
5. If the cylinder is leaking, contact a DOT approved repair shop to determine
the cause of the leak and have the shop, not you, repair it.
If a fire occurs while the machine is being operated do the following:
1. Stop the engine: turn the key switch to the off position.
2. Shut off the service valve on the propane cylinder if possible. Be
careful not to get burned.
3. Move the machine outside if possible. If not possible, move it to
ventilated area away from flammable materials.
4. Do not attempt to extinguish the flame from a gas leak. If you do, the gas
will build up in the area and could re-ignite. Starve the fire by shutting off the
supply
of gas.
5. Have the machine and cylinder inspected before using them again.
DO NOT operate or permit another person to use a trigger as a lighter near
the propane machine.
DO NOT smoke near the propane machine.
DO NOT unload the propane tank inside a building.
DO NOT store the propane tanks inside buildings.
DANGER: do not store or use gasoline or other flammable gases and
liquids near the machine.
DANGER: This machine has parts, including the pad assemblies, that can
cause severe injury if these parts are contacted while they are 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 machine in a place where unauthorized or untrained
personnel could use the machine.
DO NOT run the machine with the pad off center, damaged or missing.
DO NOT run machine with unsecured guards and shields.
DO NOT operate the machine if the machine has loose parts.
WARNING: it is forbidden to tamper with the engine. The following acts are
alleged to constitute tampering:
-tampering with the throttle body;
-tampering with magneto or electronic ignition system;
-tampering with spark plug;
-tampering with the filter elements;
-tampering with the warhead;
-tampering with the regulator;
-tampering with the Fuel valve Lock-off;
-tampering with the Crankcase;
-tampering with the breather chamber;
-tampering with the intake pipe.
