Operating Instructions
2. Use of a Ground Fault Interrupter
(GFI) is strongly recommended.
Ground Fault Interrupters can
significantly reduce the possibility of
injury if an electrical short occurs. In
order to install a GFI, the generator
neutral wire must be internally
grounded to the generator frame,
and the frame must be properly
grounded to the earth.
A Ground Fault
Interrupter may
not be effective if used on a generator
that is not grounded! Refer to the
section entitled Grounding for proper
steps to ground the generator.
3. When installing a GFI, be sure to
follow all national and local
regulations. If not sure of
regulations or procedures, obtain
assistance from a qualified (licensed
or certified) electrical technician.

1. Use the ground terminal and wing
nut on the generator frame to
connect the unit to a suitable
ground source. Securely fasten the
end terminal of the ground wire to
the ground terminal on the
generator frame. Tighten the
washer and wing nut on top of the
ground wire end terminal.
2. The ground wire should be made of
#8 gauge wire. Do not use wire with
a higher gauge number. Higher
gauge numbers indicate thinner
wire, which may not provide an
adequate ground path.
3. The other end of the ground wire
must be securely fastened to an
approved ground source.
The following are ground sources
approved by the National Electric Code.
Other ground sources may be
acceptable. Refer to the National Electric
Code and local regulations for further
ground source information. If not sure
of regulations or procedures, obtain
assistance from a qualified (licensed or
certified) electrical technician.
a. An underground water pipe at
least ten feet in length
b. A non-corrosive underground
pipe at least eight feet in length
and 3/4 inch diameter
c. A steel or iron underground rod
at least eight feet in length and
5/8 inch diameter
d. A non-ferrous rod at least eight
feet in length, 1/2 inch in

LOAD DEVICES
1. All load devices and extension cords
should use three prong terminals.
Refer to the following chart for
extension cord and cable size
requirements.
2. Allow the engine to run for 2-3
minutes before applying any
electrical loads.
3. The 120 volt receptacles are rated
for 15 amps and may be used in any
combination of 120 volt loads and
also with 240 volt loads through the
240 volt receptacles.
The 240 volt receptacles are rated
for 20 amps and may be used in any
combination of 240 volt loads and
also with 120 volt loads through the
120 volt receptacles.
The 120/240 volt twist lock
receptacle, found on some units, is
rated for 20 amps and may be used
in any combination of 120 volt and
240 volt loads.
4. Individual receptacles should not be
loaded beyond the amperage
rating.
5. Total combined load through any
combination of receptacle must not
exceed the rated load limits of the
generator. Refer to the
identification plate on the
generator for amp and wattage
specifications.
6. Always shut off and remove loads
before starting or shutting off the
generator engine.
7. When plugging multiple electrical
load devices into the generator
receptacles, be sure to connect and
activate the highest power draw
item first. Allow the generator
engine to stabilize, then connect
and activate the next highest power
draw device. The smallest power
draw device should be connected to
the receptacle and activated last.
NOTE: Power draw can be calculated
by multiplying volts and amps. The
resulting number is wattage.
Never exceed the posted maximum
wattage for the generator or any
individual receptacle. Refer to owner's
manuals and product tags to determine
the wattage of all electrical load devices.
If actual watt ratings are not available,
the following chart may be used as a
general guideline.
Remember that devices which generate
heat during operation such as heaters,
incandescent light bulbs, motors and
hair dryers have a higher power draw
than devices which generate little heat
during operation such as florescent
bulbs, radios, and clocks.
Long power cords and extension cords
also draw additional power. Keep cords
at minimum possible length.
Refer to the chart provided for
maximum limits for lengths of
extension cords.
8. Circuit protection is provided by a
circuit breaker. The circuit breaker
opens when the generator load
exceeds its maximum capacity or a
short circuit occurs. If the circuit
breaker opens, perform the following
procedures to correct the problem:
a. Shut off and disconnect all
electrical loads.
b. Attempt to determine the cause
of the electrical problem overloading or short circuit.
c. Do not use any devices that have
short circuits. Avoid overloading
the generator.
d. Press the circuit breaker
pushbutton to reset the circuit
breaker.

Repeated cycling
of the circuit
breaker indicates a problem and may
cause damage to the generator or load
devices. Do not operate the generator
if repeated cycling of the circuit
breaker occurs.
LOW OIL SHUTDOWN
A low oil shutdown switch is provided
to protect the engine and generator on
most extended run models. When
engine oil level drops too low for
proper engine operation, the low oil
shutdown switch causes the engine to
shut off. If oil level is low when
attempting to start the generator
engine, the low oil level shutdown
switch prevents the engine from
starting. If engine does not start, check
oil level.
NOTE: It is important to keep the
generator unit on a level surface. The
oil level shutdown switch can prevent
the engine from starting even if oil
level is sufficient, when the generator
unit is placed on an uneven surface.
Installation for Stand-by Use
Precautions must be taken to prevent
electrical back feeding into utility
systems. This requires isolation of the
electrical system. To isolate the
electrical system, perform the following
procedures:
1. Turn off the main electrical system
switch prior to connecting the
generator.
ESTIMATED POWER USAGE (WATTS)

Operating Instructions
2. In accordance with national and
local standards, a double throw
transfer switch must be installed in
the system.
Always shut off
main power prior
to temporary connection of the
generator to a building electrical
system.
Installation of the
generator as a
backup electrical source must be
performed by a qualified (licensed or
certified) electrical technician.
Maintenance
INFREQUENT USAGE
If the generator is used infrequently,
starting difficulty may occur. To help
prevent difficulty starting, the
generator should be run for
approximately 30 minutes per week.
STORAGE
If the generator is not to be used for
extended periods of time, the
following prestorage procedures
should be performed:
1. Make sure engine oil is filled to the
proper level.
2. Drain all fuel from the tank, lines,
carburetor and fuel valve.
3. Remove the spark plug, and pour
approximately one teaspoon of oil
into the spark plug hole.
4. Pull the starter cord several times to
spread the oil throughout the
cylinder.
5. Slowly pull the starter cord, until
resistance is felt. This indicates that
the piston is moving upward on the
compression cycle, and the intake
and exhaust valves are closed. (The
piston pushes a small amount of air
from the spark plug hole on
compression.)
6. Use of anti-gumming agents in the
fuel system can help prevent the
build up of gum and varnish.
