DANGER
Explosion and Fire. Fuel and vapors are
extremely flammable and explosive. Add fuel
in a well ventilated area. Keep fire and spark
away. Failure to do so will result in death
or serious injury.
(000166)
DANGER
Do not overfill fuel tank. Fill to 1/2 in. of top of tank to
allow for fuel expansion. Overfilling may cause fuel to
spill onto engine causing fire or explosion, which will
result in death or serious injury.

3. Clean area around fuel cap and remove
cap slowly.
4. Slowly add recommended fuel (A). Do not
overfill (B). See Figure 2-3.
5. Install fuel cap.
Figure 2-3. Add Recommended Fuel
NOTE: Allow spilled fuel to evaporate before
starting unit.
IMPORTANT NOTE: It is important to pre-
vent gum deposits from forming in fuel
system parts such as the carburetor, fuel
hose or tank during storage. Alcohol-
blended fuels (called gasohol, ethanol or
methanol) can attract moisture, which
leads to separation and formation of acids
during storage. Acidic gas can damage the
fuel system of an engine while in storage.
To avoid engine problems, the fuel system
should be emptied before storage of 30
days or longer. See the Storage section.
Never use engine or carburetor cleaner
products in the fuel tank as permanent
damage may occur.

Grounding the Generator When
Used as a Portable
The generator is equipped with an equipment
ground connecting the generator frame and
the ground terminals on the AC output recep-
tacles (see NEC 250.34 (A). This allows the
generator to be used as a portable without
grounding the frame of the generator as spec-
ified in NEC 250.34. See Figure 3-1.
• Neutral Bonded to Frame.

Special Requirements
Review all Federal or State Occupational
Safety and Health Administration (OSHA) reg-
ulations, local codes, or ordinances that apply
to the intended use of the generator.
Consult a qualified electrician, electrical
inspector, or the local agency having jurisdic-
tion:
• 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 the Generator to a
Building Electrical System
When connecting directly to a building electri-
cal system, it is recommended that a manual
transfer switch be used. Connections for a
portable generator to a building electrical sys-
tem must be made by a qualified electrician
and in strict compliance with all national and
local electrical codes and laws.
Know Generator Limits
Overloading a generator can result in damage
to the generator and connected electrical
devices. Observe the following to prevent
overload:
• Add up the total wattage of all electrical
devices to be connected at one time. This
total should NOT be greater than the gener-
ator's wattage capacity.
Asphyxiation. Running engines produce
carbon monoxide, a colorless, odorless,
poisonous gas. Carbon monoxide, if not
avoided, will result in death or serious injury.
(000103)
DANGER
(000178a)
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.

12 Owner’s Manual for Portable Generator
• The rated wattage of lights can be taken
from light bulbs. The rated wattage of tools,
appliances, and motors can be found on a
data label or decal affixed to the device.
• If the appliance, tool, or motor does not
give wattage, multiply volts times ampere
rating to determine watts (volts x amps =
watts).
• Some electric motors, such as induction
types, require about three times more watts
of power for starting than for running. This
surge of power lasts only a few seconds
when starting such motors. Make sure to
allow for high starting wattage when select-
ing electrical devices to connect to the gen-
erator:
1. Figure the watts needed to start the largest
motor.
2. Add to that figure the running watts of all
other connected loads.
The Wattage Reference Guide is provided to
assist in determining how many items the gen-
erator can operate at one time.
NOTE: All figures are approximate. See data
label on appliance for wattage requirements.

Section 4 Maintenance and Troubleshooting
Maintenance Recommendations
Regular maintenance will improve perfor-
mance and extend generator life. See a quali-
fied dealer for service.
Generator warranty does not cover items sub-
jected to operator abuse or negligence. To
receive full warranty value, operator must
maintain generator as instructed in this man-
ual, including proper storage as detailed in
Winter Storage and Long Term Storage.
NOTE: Call 1-888-GENERAC (1-888-436-
3722) with questions about component
replacement.
Maintenance Schedule
Follow maintenance schedule intervals,
whichever occurs first according to use.
NOTE: Adverse conditions will require more
frequent service.
NOTE: Go to Generac.com or contact an
IASD for replacement parts.
NOTE: All required service and adjustments
should be each season as detailed in the fol-
lowing chart.
Preventive Maintenance
Dirt or debris can cause improper operation
and equipment damage. Clean generator
daily or before each use. Keep area around
and behind muffler free from combustible
debris. Inspect all cooling air openings on
generator.
• Use a damp cloth to wipe exterior surfaces
clean.
• Use a soft bristle brush to loosen caked on
dirt, oil, etc.
• Use a vacuum to pick up loose dirt and
debris.
• Low pressure air (not to exceed 25 psi)
may be used to blow away dirt. Inspect
cooling air slots and openings on generator.
These openings must be kept clean and
unobstructed.
NOTE: DO NOT use a garden hose to clean
generator. Water can enter engine fuel system
and cause problems. If water enters generator
through cooling air slots, some water will be
retained in voids and crevices of rotor and sta-
tor winding insulation. Water and dirt buildup
on generator internal windings will decrease
insulation resistance of windings.
