• When using generator for backup power, notify utility company.
• Do not touch bare wires or 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 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 system, operating this
equipment imprudently, neglecting its maintenance or being
careless can 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, disconnect
the battery cable indicated by a NEGATIVE, NEG or (-) first.
When finished, reconnect that cable last.
• After your generator system is installed, the generator may crank
and start without warning any time there is a power failure. To
prevent possible injury, always set the generator’s system switch
to OFF, remove the service disconnect from the disconnect box
AND remove the 15 Amp fuse BEFORE working on the
equipment.
WARNING
Generator produces hazardous voltage.
Failure to properly ground generator can result in
electrocution.
Failure to isolate generator from power utility can
result in death or injury to electric utility workers
due to backfeed of electrical energy.
• DO NOT touch hot parts and AVOID hot exhaust gases.
• Allow equipment to cool before touching.
• DO NOT install the generator closer than 5 feet (1.5m) from any
combustibles or structures with combustible walls having a fire
resistance rating of less than 1 hour.
• Keep at least 3 ft. (91 cm) clearance on all sides of generator
including overhead.
• Code of Federal Regulation (CFR) Title 36 Parks, Forests, and
Public Property require equipment powered by an internal
combustion engine to have a spark arrester, maintained in
effective working order, complying to USDA Forest service
standard 5100-1C or later revision. In the State of California a
spark arrester is required under section 4442 of the California
Public resources code. Other states may have similar laws.
WARNING
Contact with muffler area can result in serious
burns.
Exhaust heat/gases can ignite combustibles or
structures causing a fire.
• Install the fuel supply system according to applicable fuel-gas
codes.
• Before placing the generator system into service, the fuel system
lines must be properly purged and leak tested.
• After the generator is installed, you should inspect the fuel
system periodically.
• NO leakage is permitted.
• DO NOT operate engine if smell of fuel is present or other
explosive conditions exist.
• DO NOT smoke around the generator. Wipe up any oil spills
immediately. Ensure that no combustible materials are left in the
generator compartment. Keep the area near the generator clean
and free of debris.
WARNING
Propane and Natural Gas are extremely flammable
and explosive.
Fire or explosion can cause severe burns or
death.
