WARNING
Generator produces hazardous voltage.
Failure to properly ground generator could result
inelectrocution.
Failure to isolate generator from
utility power could result in death or serious injury
to electric utility workers, due to back-feed of electrical
energy.
• DO NOT touch bare wires or bare receptacles.
• DO NOT use generator with electrical cords which are
worn, frayed, bare, or otherwise damaged.
• DO NOT handle generator or electrical cords while
standing in water, while barefoot, or while hands or feet
are wet.
• If you must work around a unit while it is operating,
stand on an insulated dry surface to reduce the risk of a
shock hazard.
• DO NOT allow unqualified persons or children to operate
or service generator.
• In case of an accident caused by electrical shock,
immediately shut down the source of electrical power and
contact the local authorities. Avoid direct contact with the
victim.
• Despite the safe design of the generator, operating this
equipment imprudently, neglecting its maintenance, or
being careless could cause possible injury or death.
• Remain alert at all times while working on this equipment.
Never work on the equipment when you are physically or
mentally fatigued.
• Before performing any maintenance on the generator, first
disconnect the battery cable indicated by a NEGATIVE,
NEG, or (-). When finished, reconnect that cable last.
• After your system is installed, the generator may crank
and start without warning any time there is a power
failure. BEFORE working on the equipment, and to
prevent possible injury, always set the generator system
switch to OFF, remove the service disconnect fuse from
the disconnect box, and remove the 15 Amp fuse.
