Prepare Generator for Use
Asphyxiation. Running engines produce carbon
monoxide, a colorless, odorless, poisonous
gas. Carbon monoxide, if not avoided, will
result in death or serious injury.
Asphyxiation. The exhaust system must be properly
maintained. Do not alter or modify the exhaust system
as to render it unsafe or make it noncompliant with
local codes and/or standards. Failure to do so will
result in death or serious injury.
Asphyxiation. Always use a battery operated carbon
monoxide alarm indoors and installed according to
the manufacturer's instructions. Failure to do so
could result in death or serious injury.
Risk of fire. Do not use generator without
spark arrestor installed. Failure to do so
could result in death or serious injury.
Risk of Fire. Hot surfaces could ignite
combustibles, resulting in fire. Fire could
result in death or serious injury.
Hot Surfaces. When operating machine, do not
touch hot surfaces. Keep machine away from
combustibles during use. Hot surfaces could
result in severe burns or fire.
Equipment and property damage. Disconnect
electrical loads prior to starting or stopping unit.
Failure to do so could result in equipment and
property damage.
