Carbon Monoxide Hazards
Operator Responsibility
IMPORTANT SAFETY INFORMATION
Be sure that anyone who operates the generator receives proper
instruction. Do not let children operate the generator without
parental supervision.
USR generators are designed to give safe and dependable service if
operated according to instructions. Read and understand this owner's
manual before operating your generator. You can help prevent
accidents by being familiar with your generator'scontrols, and by
observing safe operating procedures.
Know how to stop the generator quickly in case of emergency.
Understand the use of all generator controls, output receptacles,
and connections.
Exhaust contains poisonous carbon monoxide, a colorless and
odorless gas. Breathing carbon monoxide can cause loss of
consciousness and may lead to death.
If you run the generator in an area that is confined, or even partially
enclosed area, the air you breathe could contain a dangerous
amount of exhaust gas.
Never run your generator inside a garage, house or near open
windows or doors.

Electric Shock Hazards
Fire and Burn Hazards
Fuel vapors are extremely flammable and may ignite after the
engine has started. Make sure that any spilled fuel has been wiped
up before starting the generator.
Gasoline is extremely flammable and is explosive under certain
conditions. Do not smoke or allow flames or sparks where the
generator is refueled or where gasoline is stored. Refuel in a well-
ventilated area with the engine stopped.
The muffler becomes very hot during operation and remains hot for
a while after stopping the engine. Be careful not to touch the muffler
while it is hot. Let the engine cool before storing the generator
indoors.
Keep the generator at least 3 feet (1 meter) away from buildings
and other equipment during operation.
Do not enclose the generator in any structure.
Keep flammable materials away from the generator.
Never connect different generator models and types.
The generator produces enough electric power to cause a serious
shock or electrocution if misused.
Using a generator or electrical appliance in wet conditions, such as
rain or snow, or near a pool or sprinkler system, or when your hands
are wet, could result in electr ocution. Keep the generator dry.
If the generator is stored outdoors, unprotected from the weather,
check all of the electrical components on the control panel before
each use. Moisture or ice can cause a malfunction or short circuit in
electrical components which could result in electrocution.
Do not connect to a building electrical system unless an isolation
switch has been installed by a qualified electrician.
Use only a USR approved parallel operation kit (optional
equipment) when connecting two generators for parallel operation.
The exhaust system gets hot enough to ignite some materials.
