General Guidelines
●Keep children away from the generator.
●To prevent accidental or remote starting while working on the generator, disconnect the negative
(-) battery cable at the battery.
●Keep the generator and its compartment clean. Excess oil and oily rags can catch fire. Dirt and
gear stowed in the compartment can restrict cooling air.
●Make sure all installed fasteners have been secured and torqued properly.
●Do not work on the generator when mentally or physically fatigued or after consuming alcohol or
drugs.
●Used engine oil has been identified by some state and federal agencies as causing cancer or
reproductive toxicity. Do not ingest, inhale or allow bare skin to come into contact with used oil or
its vapors.
●Benzene and lead in some gasoline mixtures have been identified by some state and federal
agencies as causing cancer or reproductive toxicity. Do not ingest, inhale or allow bare skin to
come into contact with gasoline or its vapors.
●Keep multi-class ABC fire extinguishers handy. Class A fires involve ordinary combustible
materials such as wood and cloth; Class B fires involve combustible and flammable liquid fuels
and gaseous fuels; Class C fires involve live electrical equipment.
●Installation and operation of the generator must comply with all applicable local, state and
federal codes and regulations.
The Exhaust Produced By The Generator Is Deadly
Substances in combustion exhaust gases have been identified by some state and federal agencies to
cause cancer or reproductive toxicity. Do not breathe in or come into contact with exhaust gases.
Carbon monoxide is produced as part of the combustion process and is a poisonous gas. Inhalation of this
gas can cause serious personal injury or death. Make sure carbon monoxide is not being inhaled by
occupants of the vehicle as well as others working on or around the generator.
1. Learn the symptoms of carbon monoxide poisoning. Carbon monoxide is colorless, odorless,
tasteless and non-irritating. It cannot be seen or smelled. Exposure to even low levels of carbon
7

monoxide for a prolonged period can lead to asphyxiation. Mild effects of carbon monoxide
poisoning include headache, dizziness, drowsiness, fatigue, chest pain and confusion. More
extreme symptoms include vomiting, seizure and loss of consciousness.
3. Never sleep in the vehicle while the generator is running unless the vehicle is equipped with a
working carbon monoxide detector.
4. Make sure there is ample fresh air when operating the generator in a confined area.
5. Disable any automatic starting feature of an inverter-charger or other automatic starting device
before storing the vehicle or parking it in a garage or other confined space.
6. The exhaust system must be installed in accordance with the Flex Power Generator Installation
Manual. (available here: https://rvmp.co/manuals).
7. Engine cooling air must not be used for heating the working or living space or compartment.
Gasoline And Propane Are Flammable And Explosive
Fuel and fuel vapor are highly explosive. Do not smoke or turn electrical switches on or off where fuel
fumes are present or in areas sharing ventilation with fuel tanks or equipment. Keep flame, sparks,
pilot lights, arc-producing equipment and all other sources of ignition well away from fuel lines and fuel
sources. Fuel lines must be secured, free of leaks and separated and/or shielded from electrical wiring.
• Fuel leaks can lead to explosive accumulations of gas or vapor.
• LP sinks when released and can accumulate inside housings, basements and other below-grade
spaces.
Generator AC Output Voltage Is Dangerous
The generator must not be connected to shore power or to any other source of electrical power without
the use of an approved transfer switch. Connecting the generator to utility power during a power
outage can cause electric shock, resulting in severe personal injury or death, as well as damage to
equipment.
1 Disable any automatic starting feature of an inverter-charger or other automatic starting device
before servicing the generator.
2 Generator electrical output connections must be made by a trained and experienced electrician and
in accordance with applicable codes.
3 Use caution when working on live electrical equipment. Remove jewelry, make sure clothing and
shoes are dry, stand on a dry wooden platform or rubber insulating mat and use tools with
insulated handles.

Gas Emitted From Batteries Is Explosive
Battery gas is highly explosive and may result in death, serious personal injury and/or severe product
and property damage. Battery compartments must be adequately ventilated per RVIA guidelines (see
RVIA/NFPA 1192 Section 2-3). Wear appropriate personal protective equipment when working on the
battery and do not smoke around the battery. Disconnect the negative battery cable first and
reconnect it last.
• Wear safety glasses.
• Do not smoke.
• To reduce arcing when disconnecting or reconnecting battery cables, always disconnect the negative
(-) battery cable first and reconnect it last.
Moving Parts Can Cause Injury
Hot, moving, and electrically-live parts can result in death, serious personal injury and/or severe
product and property damage. Make sure protective guards are in place, use trained personnel to
make adjustments and do not wear loose clothing near moving parts.
• Make sure all protective guards are property installed before starting the generator.
• Use only trained personnel to make adjustments to the generator while it is running.
• Moving parts can catch loose items, such as clothing or jewelry. Do not wear loose clothing or
jewelry near moving parts such as power take-off shafts, fans, belts and pulleys.
• Moving parts can entangle appendages, including fingers. Keep the protective guards in place over
the fans, belts, pulleys and other moving parts and keep hands away from all moving parts.
