GENERATOR SAFETY

SAFETY LABEL LOCATIONS

If a label comes off or becomes hard to read, contact your USR

generator dealer for a replacement.

These labels warn you of potential hazards that can cause serious

injury. Read them carefully.

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.
