USING THE GENERATOR
System Ground
The generator has a system ground that connects the
generator frame components to the ground terminals
on the AC output receptacles.
Special Requirements
There may be National regulations, local codes, or
ordinances that apply to the intended use of the
generator. Please consult a qualified electrician,
electrical inspector, or the local agency having
jurisdiction.
•In some areas, generators are required to be
registered with local utility companies.
•If the generator is used at a construction site, there may
be additional regulations which must be observed.
Connecting to a Building's Electrical System
Connections for standby power to a building's
electrical system must be made by a qualified
electrician. The connection must isolate the generator
power from utility power, and must comply with all
applicable laws and electrical codes.
WARNING
Generator produces powerful voltage.
Failure to isolate generator from power utility
can result in death or injury to electric utility
workers due to backfeed of electrical energy.
•When using generator for backup power, notify
utility company. Use approved transfer equipment to
isolate generator from electric utility.
•Use a ground fault circuit interrupter (GFCI) in any
damp or highly conductive area, such as metal
decking or steel work.
•DO NOT touch bare wires or receptacles.
•DO NOT use generator with electrical cords which
are worn, frayed, bare or otherwise damaged.
•DO NOT operate generator in the rain.
•DO NOT handle generator or electrical cords while
standing in water, while barefoot, or while hands or
feet are wet.
•DO NOT allow unqualified persons or children to
operate or service generator.

WARNING
Running generator gives off carbon monoxide,
an odorless, colorless, poison gas.
Breathing carbon monoxide will cause nausea,
fainting or death.
•Operate generator ONLY outdoors.
•Keep exhaust gas from entering a confined area
through windows, doors, ventilation intakes or other
openings.
•DO NOT operate generator inside any building or
enclosure, including the generator compartment of a
recreational vehicle (RV).
The generator must be at least 2m (5 ft.) from
structures having combustible walls and/or other
combustible materials. Leave at least Im (3 ft.) all
around generator including overhead, for adequate
cooling, maintenance and servicing.
Place generator in a well ventilated area, which will
allow for removal deadly exhaust gas. DO NOT
place generator where exhaust gas could accumulate
and enter inside or be drawn into a potentially
occupied building. Ensure exhaust gas is kept away
from any windows, doors, ventilation intakes or other
openings that can allow exhaust gas to collect in a
confined area (Figure 2).Prevailing winds and air
currents should be taken into consideration when
positioning generator.
