120 VAC, Duplex Receptacle
The 120 Volt outlet is overload protected by
the inverter module electronic control. See
Figure 2-4. Each receptacle will power 120
Volt AC, single phase, 60 Hz electrical loads
requiring up to 1600 watts (1.6 kW).
NOTE: Limit length of extension cords to fif-
teen feet, or less, to prevent voltage drop and
overheating of wires.
Figure 2-4. 120 VAC, Duplex Receptacle
PowerDial
The PowerDial controls the ON/OFF func-
tions, choke and fuel valve operation. See Fig-
ure 2-5.
• The START position (1) is used to start the
engine. In this position, the fuel is on and
the choke is fully on (closed).
• The RUN position (2) for normal operation
and to gradually reduce the use of the
choke.
• The STOP position (3) stops the engine
and shuts off fuel flow.
Figure 2-5. PowerDial (example)
PowerBar
The PowerBar indicates the amount of power
being used from the generator. Each section
is approximately 20%.
Economy Switch
The economy switch has 3 modes of opera-
tion:
•Economy: The quietest mode and best
when running appliances or equipment that
are resistive loads (non-motor starting),
(example: TV, video game, fan, light, radio).
•Standard: Best when running a both induc-
tive (motor-starting loads) and resistive
(non-motor starting loads), especially when
these loads are turning on and off (exam-
ple: RV, air conditioner).
•Turbo: Best when running inductive loads
(appliances or equipment with motor-start-
ing) that are continually running (examples:
drill, blender, saw, hairdryer).
Generator Status Lights
See Figure 2-6.
•Over Temperature LED (red): Illuminates
when unit temperatures exceed normal
operating conditions (1). The ready LED
will turn off and the inverter will cut power to
the outlets. Check for airflow obstructions
at front and rear panels. The engine will
remain running to cool the unit with the over
temperature LED illuminated. Once the unit
has reached normal operating tempera-
tures, the over temperature LED will turn
off. The reset button must then be pressed
for 1 second and released to clear the fault
and restore output power.
•Low Oil Level LED (orange): Illuminates
when oil level is below safe operating level.
Engine shuts down (2).
•Ready LED (green): Indicates output from
generator (3) (unless there is a low oil or
overload condition).
•Overload LED (red): Indicates system
overload (4). During motor starting it is nor-
mal for the overload LED to illuminate for a
few seconds. If LED stays illuminated and
the ready LED turns off, the engine will con-
tinue to run without output power. Remove
all applied loads and determine if attached
devices exceed recommended output
power. Review for any faulty or shorted
connections. Press and hold the reset but-
ton for 1 second and release. The red over-
load LED should turnoff. Loads can be re-
applied once the green ready LED illumi-
nates. If the red LED returns, contact an
IASD.

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 Ground
Figure 3-1.Grounding the Generator
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.
• 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.
Wattage Reference Guide is provided to assist
in determining how many items the generator
can operate at one time.
NOTE: All figures are approximate. See data
label on appliance for wattage requirements.
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
(000179a)
DANGER
The exhaust system must be properly maintained. Do
not alter or modify the exhaust system as to render it
unsafe or make it noncompliant with local codes and/or
standards. Failure to do so will result in death
or serious injury.
(000118)
DANGER
Risk of fire. Do not use generator without
spark arrestor installed. Failure to do so
could result in death or serious injury.
(000178a)

Low Oil Level Shutdown System
The engine is equipped with a low oil level
sensor that shuts down the engine automati-
cally when the oil level drops below a speci-
fied level. See Figure 3-3 (B). The engine will
not run until the oil has been filled to the
proper level.
If the engine shuts down and there is sufficient
fuel, check engine oil level.
Parallel Operation
For output power up to 3200W, two iQ2000
inverters can operate in parallel using Gen-
erac’s Smart Parallel Kit (optional). See the
Smart Parallel Kit Operator’s Manual or con-
tact an IASD.
NOTE: All connections to the parallel kit
should be made while both inverters are
turned off and all loads disconnected.
1. The economy mode switch for both units
must be matching and set to either stan-
dard or turbo.
2. Make appropriate parallel connections to
the 120V duplex outlets on each iQ2000
inverter as outlined in the owner’s manual
supplied with the kit.
NOTE: Do not disconnect any parallel kit con-
nections once the units are running.
3. Start both units per starting instructions.
Once the green output indicator illumi-
nates, devices can be connected and
turned on using the parallel kit outlet.

Section 4 Maintenance and Troubleshooting
Maintenance Recommendations
Regular maintenance will improve perfor-
mance and extend generator life. See an
IASD 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: 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.
Engine Maintenance
Engine Oil Recommendations
Only high-quality detergent oils classified for
service SF, SG, SH, SJ or higher are recom-
mended. DO NOT use special additives.
Climate determines proper engine oil viscos-
ity. See chart to select correct viscosity.

Owner’s Manual for Portable Generator 15
It is recommended to start and run the genera-
tor for 30 minutes, every 30 days. If this is not
possible, refer to the following list to prepare
unit for storage.
• DO NOT place a storage cover on a hot
generator. Allow unit to cool to room tem-
perature before storage.
• DO NOT store fuel from one season to
another unless properly treated.
• Replace fuel container if rust is present.
Rust in fuel will cause fuel system prob-
lems.
• Cover unit with a suitable protective, mois-
ture resistant cover.
• Store unit in a clean, dry area.
• Always store generator and fuel away from
heat and ignition sources.
Prepare Fuel System/Engine for

damage fuel system components. Keep fuel
fresh, use fuel stabilizer.
If fuel stabilizer is added to fuel system, pre-
pare and run engine for long term storage.
Run engine for 10-15 minutes to circulate sta-
bilizer throughout fuel system. Adequately
prepared fuel can be stored up to 24 months.
NOTE: If fuel has not been treated with fuel
stabilizer, it must be drained into an approved
container. Run engine until it stops from lack
of fuel. Use of fuel stabilizer in fuel storage
container is recommended to keep fuel fresh.
