DANGER
CARBON MONOXIDE
Using a generator indoors CAN KILL YOU IN MINUTES.
Generator exhaust contains carbon monoxide (CO). This is a poison you cannot see or
smell. If you can smell the generator exhaust, you are breathing CO. But even if you cannot
smell the exhaust, you could be breathing CO.
• NEVER use a generator inside homes, garages, crawlspaces, or other partly enclosed
areas. Deadly levels of carbon monoxide can build up in these areas. Using a fan or
opening windows and doors does NOT supply enough fresh air.
• ONLY use a generator outside and far away from windows, doors, and vents. These
openings can pull in generator exhaust.
Even when you use a generator correctly, CO may leak into the home. ALWAYS use a
battery-powered or battery-backup CO alarm in the home.
If you start to feel sick, dizzy, or weak after the generator has been running, move to fresh
air RIGHT AWAY. See a doctor. You could have carbon monoxide poison.

GV 7000A / 7003A Safety Information
2.1 Operating Safety
BACKFEED FROM THE GENERATOR INTO THE PUBLIC POWER
DISTRIBUTION SYSTEM CAN CAUSE SERIOUS INJURY OR
DEATH TO UTILITY WORKERS!
DANGER
WARNING
Improper connection of generator to a building's electrical system can
allow electrical current from the generator to backfeed into utility lines.
This may result in electrocution of utility workers, fire, or explosion.
Connections to a building's electrical system must be made by a
qualified electrician and comply with all applicable laws and electrical
codes.
If connected to a building's electrical system the generator must meet
the power, voltage, and frequency requirements of the equipment in
the building. Differences in power, voltage, and frequency
requirements may exist and improper connection may lead to
equipment damage, fire, and personal injury or death.
Familiarity and proper training are required for the safe operation of
equipment. Equipment operated improperly or by untrained personnel
can be dangerous. Read the operating instructions contained in both
this manual and the engine manual and familiarize yourself with the
location and proper use of all controls. Inexperienced operators should
receive instruction from someone familiar with the equipment before
being allowed to operate the machine.
2.1.1 NEVER operate the generator when open containers of fuel, paint, or
other flammable liquids are near.
2.1.2 NEVER operate the generator, or tools attached to the generator, with
wet hands.
2.1.3 NEVER use worn electrical cords. Severe electrical shock and
equipment damage may result.
2.1.4 NEVER run the electrical cords under the generator, or over vibrating
or hot parts.
2.1.5 NEVER enclose or cover the generator when it is in use or when it is
hot.
2.1.6 NEVER overload the generator. The total amperage of the tools and
equipment attached to the generator must not exceed the load rating
of the generator.
2.1.7 NEVER operate the machine in snow, rain, or standing water.
2.1.8 NEVER allow untrained personnel to operate or service the generator.
The generator set should be set up by a trained electrician.
2.1.9 ALWAYS store the equipment properly when it is not being used.
Equipment should be stored in a clean, dry location out of the reach of
children.

Safety Information GV 7000A / 7003A
2.1.10 ALWAYS be sure the machine is on a firm, level surface and will not
tip, roll, slide, or fall while operating.
2.1.11 ALWAYS transport the generator in an upright position.
2.1.12 ALWAYS keep the machine at least one meter (three feet) away from
structures, buildings, and other equipment during use.
2.1.13 ALWAYS keep the area immediately surrounding and underneath the
machine clean, neat, and free of debris and combustible materials.
Make sure that the area overhead is clear of debris that could fall onto
or into the machine or exhaust compartment.
2.1.14 ALWAYS remove all tools, cords, and other loose items from the
generator before starting it.
2.1.15 DO NOT ground this generator.
2.2 Operator Safety while using Internal Combustion Engines
Internal combustion engines present special hazards during operation
and fueling. Read and follow the warning instructions in the engine
owner’s manual and the safety guidelines below. Failure to follow the
DANGER
warnings and safety guidelines could result in severe injury or death.
2.2.1 DO NOT run the machine indoors or in an enclosed area such as a
deep trench unless adequate ventilation, through such items as
exhaust fans or hoses, is provided. Exhaust gas from the engine
contains poisonous carbon monoxide gas; exposure to carbon
monoxide can cause loss of consciousness and may lead to death.
2.2.2 DO NOT smoke while operating the machine.
2.2.3 DO NOT smoke when refueling the engine.
2.2.4 DO NOT refuel a hot or running engine.
2.2.5 DO NOT refuel the engine near an open flame.
2.2.6 DO NOT spill fuel when refueling the engine.
2.2.7 DO NOT run the engine near open flames.
2.2.8 DO NOT start the engine if fuel has spilled or a fuel odor is present.
Move the generator away from the spill and wipe the generator dry
before starting.
2.2.9 ALWAYS refill the fuel tank in a well-ventilated area.
2.2.10 ALWAYS replace the fuel tank cap after refueling.
2.2.11 ALWAYS check the fuel lines and the fuel tank for leaks and cracks
before starting the engine. Do not run the machine if fuel leaks are
present or the fuel lines are loose.
