being miles from civilization.

DANGER:This generator produces poisonous carbon monoxide gas when running. This
gas is both odorless and colorless. Even if you do not see or smell gas, carbon monoxide
may still be present. Breathing this poison can lead to headaches, dizziness, drowsiness,
and eventually death.
●Use outdoors ONLY in non-conned areas.
●Keep several feet of clearance on all sides to allow proper ventilation of the generator.
WARNING: The exhaust from this product contains chemicals known to the State of
California to cause cancer, birth defects, or other reproductive harm.
WARNING: This generator produces heat when running. Temperatures near exhaust can
exceed 150°F (65°C).
●Do not touch hot surfaces. Pay attention to warning labels on the generator denoting
hot parts of the machine.
●Allow generator to cool several minutes after use before touching engine or areas
which heat during use.
GENERAL SAFETY PROCEDURES
Please familiarize yourself with the following safety symbols and words:
●DANGER: Indicates a hazard that will result in serious injury or death if instructions are not
followed.
●WARNING: Indicates a strong possibility of causing serious injury or death if instructions are not
followed.
●CAUTION: Indicates a possibility of personal injury or equipment damage if instructions are not
followed.
SAFETY ALERT SYMBOL
The safety alert symbol is used with one of the safety words (DANGER,
WARNING, or CAUTION) to alert you of hazards. Please pay attention to
these hazard notices both in this manual and on the engine.

WARNING: This generator may emit highly ammable and explosive gasoline vapors,
which can cause severe burns or even death. A nearby open ame can lead to an
explosion even if not directly in contact with gasoline.
●Do not operate near an open ame.
●Do not smoke near the generator.
●Always operate on a rm, level surface.
●Always turn the generator o before refueling.
●Allow generator to cool for at least 2 minutes before removing the fuel cap. Loosen
cap slowly to relieve pressure in the tank.
●Do not overll the gas tank. Gas may expand during operation. Do not ll to the top
of the tank.
●Always check for spilled gas before operating.
●Empty the gasoline tank before storing or transporting the generator.
●Before transporting, turn the fuel valve to the o position and disconnect
the spark plug.
WARNING:This generator produces a powerful voltage, which can result in electrocution.
●ALWAYS ground the generator before using it (see the “Grounding the Generator”
portion of the “PREPARlNG THE GENERATOR FOR USE section).
●The generator should only be plugged into electrical devices, either directly or with
an extension cord. NEVER connect to a building electrical system without a qualied
electrician. Such connections must comply with local electrical laws and codes. Failure
to comply can create a back-ow of power, which may result in serious injury or death
to utility workers.
●Use a ground fault circuit interrupter (GFCI) in highly conductive areas such as metal
decking or steelwork. GFCls are available in-line with some extension cords.
●Do not use uncovered in rainy or wet conditions.
●Do not touch bare wires or receptacles (outlets).
●Do not allow children or non-qualied persons to operate.

GENERAL SAFETY PROCEDURES (CONTINUED)
In addition to the above safety notices, please familiarize
yourself with the safety and hazard markings on the
generator.

CARBON MONOXIDE SAFETY
Carbon Monoxide
CO-ALERT
●The indicator will light red.
●The engine will shutdown.
●The engine will not restart for 5 minutes.
Maintenance Required
If an error in the CO-ALERT system is detected the
indicator will light yellow. Please contact DuroMax
service at 844-DUROMAX for assistance.
Description
The DuroMax CO-ALERT system was created to protect
our customers and their families from dangerous carbon
monoxide. Just like the detector for your home the CO-
ALERT tests the air for to keep you safe and healthy.
CO Detected
If dangerous carbon monoxide levels are detected:
Generators are convenient, but they can also be dangerous. All fuel-
burning appliances and equipment release a poisonous gas called carbon
monoxide.
Carbon monoxide (also known as CO) can be dangerous for humans
and pets, even in small amounts, because it blocks oxygen from getting
into your body. Carbon monoxide poisoning can lead to death in a very
short time. It is odorless, tasteless and invisible, so you may be exposed
without knowing it. That is why carbon monoxide is sometimes called
“the silent killer.”
12

As the only safe way to use a portable generator, taking your
generator outside is absolutely mandatory to keep your family
safe from carbon monoxide. But there’s even more you can do.
By educating yourself about all carbon monoxide risks, you’ll
be better prepared to protect your family from this colorless,
odorless threat. Visit takeyourgeneratoroutside.com for more
information.
