WARNING
READ and UNDERSTAND this manual completely before using the generator! Failure to properly set up,
operate, and maintain this generator could result in serious injury or death from carbon monoxide poisoning,
electric shock, fire/explosion, or burns. In particular, be aware of the following hazards:
CO Poisoning
Generators give off carbon monoxide, a poisonous gas that can kill you. You CANNOT smell it, see it, or taste it.
• ONLY run generator OUTDOORS and AWAY from building air intakes. NEVER run generator inside any enclosed or
semi-enclosed spaces, including homes, basements, garages, sheds, boxes, RVs, boats or pick-up truck beds. These
spaces can trap poisonous gases, EVEN if you run a fan or open windows.
• Install carbon monoxide alarms inside nearby structures/buildings (battery-operated, or plug-in with battery backup).
Electric shock / Electrocution
• High voltage electricity from generator can kill. DO NOT operate in wet locations. Be sure generator is properly
grounded. Use only UL-listed, outdoor-rated grounded extension cords of proper size.
• NEVER plug the generator directly into a wall outlet. ANY connection to a building’s electrical system MUST
ISOLATE THE GENERATOR FROM UTILITY POWER via a UL-approved transfer switch installed by a licensed
electrician. Otherwise, back feed from the generator into the power grid could kill utility workers.
Fire / Explosion
• DO NOT overload generator (per rated capacity), and OPERATE ONLY in an area with adequate cooling ventilation so
engine does not overheat. Exhaust can be extremely hot. Keep muffler at least 7’ from all combustible objects.
• All fuels are flammable. Never fuel a running or hot engine. Never pump fuel directly into generator at gas station – use
approved container to transfer fuel. Ensure there are no fuel leaks, and keep sources of sparks and flames away.
• ALWAYS keep a fire extinguisher rated “ABC” nearby.
STOP!
CHOOSE THE RIGHT GENERATOR FOR YOUR NEEDS. See the “Power load Planning & Management” section
of this manual to determine your power load requirements and then compare to the generator’s rated capacity.
INSPECT COMPONENTS: Closely inspect to make sure no components are missing or damaged. See the “Unpacking
& Delivery Inspection” section for instructions on whom to contact to report missing or damaged parts.
ARRANGE FOR PROFESSIONAL INSTALLATION of a transfer switch if you will be connecting the generator to
your building’s electrical system. See the “Installation/Initial Set-Up” section for more information about this
requirement. Any Questions, Comments, Problems, or Parts Orders

WARNING
NEVER exceed the rated wattage capacity of your generator.
OVERLOADING may cause SERIOUS DAMAGE to the generator and
attached electrical devices, and may result in fire.
Your generator MUST BE SIZED PROPERLY to provide both the running and starting (surge)
wattage of the devices you will be powering. Before using your generator, determine the running
and starting wattage requirements of all the electrical devices you will be powering simultaneously.
The sum of the running and starting wattages of the devices being powered must not exceed the
continuous output rating of your generator. (The continuous output rating of your generator is listed
in the “Specifications” section of this manual.) Note that:
• Devices without electric motors such as light bulbs, radios, and televisions have the same
running and starting wattage.
• Devices with electric motors such as refrigerators, compressors, and hand tools typically
require a starting wattage that is 3 to 5 times greater than the running wattage.
The running and starting wattage requirements are often listed on a device’s nameplate. If wattage
is not given on the device’s nameplate, the wattage may be calculated by multiplying the nameplate
voltage by nameplate amperage, Watts = Volts X Amps.
Example conversion to watts:
120 Volts X 5 Amps = 600 Watts
If only the running voltage is given on the nameplate for a device with an electric motor, the starting
wattage can be approximated to be three to five times the running wattage.
Estimates for the running wattage requirements for common devices are listed in Table 1 below.
Guidance for starting wattages is provided in the table’s footnotes.

(a) Hard-starting motors require 3-5 times the rated running watts
(b) For extremely hard to start loads such as air conditioners and air compressors, consult the equipment dealer to
determine maximum wattage
To calculate the running and starting wattage requirements for the devices you will be
powering, follow these steps:
1. Make a list of all electrical devices you will be powering at the same time with the generator.
2. List the greater of the running or starting wattage next to each device as obtained from the
devices’ nameplate or Table 1. If only the running wattage for a device with an electric
motor is known, the starting wattage can be estimated to be at least 3 times the running
wattage.
3. Add the wattages for all devices on your list. This total must be lower than the continuous
output rating of your generator.
Example:
Device to be Powered Greater of Starting/Running Wattage
Light Bulb 75 W
Refrigerator – 18 Cu. Ft. 1600 W
Microwave 700 W
Window AC 1800 W
Sump pump (1/3 hp) 2100 W
Total 6275W
In this example, the generator must have a continuous output of at least 6275 W in order to
power all of the devices simultaneously.
You can increase the number of devices your generator can power by staggering the load on the
generator. For example, you could alternately power your refrigerator and air conditioner for
limited periods of time -- powering only one of the devices at a time and never powering both at the
same time.

Installation / Initial Set-Up
12
There are a number of important steps required to set up your generator for initial use. These
steps are:
Steps for Installation / Initial Set-Up
1. Unpacking & delivery inspection.
2. Planning the power load to stay within the generator’s rated
capacity.
3. Setting up generator for the type of power generation you need:
a. portable power source, or
b. connected to a building as a back-up power source.
4. Selecting a site for using the generator.
5. Grounding.
Each of these steps is discussed in detail below:
1. Unpacking & Delivery Inspection
You should inspect the generator immediately after you receive delivery.
See the “Machine Component Identification” section of this manual for a
diagram of the generator and its components.
• If you have missing components, contact Product Support at 1-800-270-0810.
• If you have damaged components, contact the freight company that delivered the unit and file a claim.
2. Planning the Power Load
Plan your power load so that you do not exceed the generator’s rated capacity.
See the “Power Load Planning & Management” section of this manual to review how to plan and
manage power loads for the generator.

Installation / Initial Set-Up
13
3. Set-up either as a BUILDING BACK-UP or PORTABLE Power Source
This generator is designed to provide up to 8000W of electrical power. It can supply electricity in
two ways:
1. As a back-up, standby power source for a building. For this application, you must arrange
for a licensed electrician to connect the generator to your building’s electrical system via the
installation of an UL-approved transfer switch. The transfer switch must be installed in
accordance with building electrical code and guidelines supplied by your power company.
2. As a portable power source. You can plug appliances or tools directly into the generator’s
electrical outlets.
Specific requirements for each are given below.
Note: Regardless of whether you use your generator as a back-up power source connected to a
building or as a portable power source, you must not overload the generator. Overloading
may cause serious damage to the generator and attached electrical devices.
Using as a
Back-up Power
Source for a
Building
Contact a licensed electrician to install a UL-approved transfer switch if
you want to use your generator as a back-up power source for a building.
What does a transfer switch do? It:
a) Safely connects the generator to your building’s electrical system by
isolating your generator from your utility company’s power lines, AND
b) Connects your generator to a critical subset of your building’s circuits
that are needed for emergency power needs.
If your generator will be connected to your building’s electrical system, it
MUST ALWAYS be isolated from the utility power grid with a UL-approved
transfer switch installed by a licensed electrician in compliance with all
applicable building and electrical codes, and in accordance with guidelines
supplied by your power company.
DANGER:
A transfer switch must be installed in order to isolate your
generator from the utility power grid. If your generator is NOT
properly isolated from the utility system, serious hazards will
arise:
♦ When your generator is running, it’s output will back feed into
the utility power line and transformer that are normally used to
provide you with power. The transformer will step up the
current to the normal line voltage. An unsuspecting utility line
worker working on what he thinks is a deactivated line could
be electrocuted.
♦ If your generator is connected (running or not) when utility
power is restored, your generator will be destroyed. It could
also explode or cause fire.
In addition to isolating your generator from the utility system, the transfer
switch connects your generator to a limited set of circuits in your building
that have been chosen as critical to operate during a power outage.

Installation / Initial Set-Up
14
The generator cannot power your entire home -- you must work with the
installing electrician to determine which devices/appliances you wish to
power during an outage. The electrician can help you determine which
circuits and devices can be powered simultaneously without overloading the
generator.
(See the previous section of this manual entitled “Power Load Planning &
Management” for more information on load application and selection.)
Using as a
Portable Power
Source
When using the generator as a portable power source, you can plug
electric devices and appliances directly into the generator’s electrical
outlets.
There are three different kinds of electrical outlets on the generator:
1. One 120/240 Volt, 30 Amp locking receptacle (NEMA L14-30R
locking receptacle compatible with L14-30P mating plug).
2. One 120 Volt, 20 Amp duplex straight-blade receptacle (NEMA 5-
20R duplex receptacle compatible with NEMA 5-20P or 5-15P mating
plugs).
3. One 120 Volt, 15 Amp duplex straight-blade receptacle (NEMA 5-
15R receptacle compatible with NEMA 5-15P mating plug).
(See more technical detail about these receptacles and their associated
circuit breakers in the “Machine Component Identification” section of this
manual.)
♦ Make sure you plug each electrical device/appliance into the correct
generator outlet based on the device’s plug configuration and
voltage/amperage rating. Never exceed the amperage rating of an outlet.
♦ Extension cords may be used to power devices that are located at a
distance from the generator. However, use only UL-listed, outdoor-rated,
grounded extension cords of the proper size. Use Table 2 to choose an
adequately sized extension cord according to the amperage of the device
being used and the length of the cord.

4. Select a Suitable Site
Before using the generator, you must select a suitable OUTDOOR location for installation and
operation. This location should meet all of the criteria listed below.
WARNING:
You must choose a suitable site for operating your generator to avoid equipment
damage and/or injury and possible death from carbon monoxide poisoning, electric
shock, or fire. Choose a site that meets all of the criteria specified.
Dry, level surface The generator should be positioned on a dry, firm, level surface.
Ensure that the generator sits level and will not slide or shift during operation.
If applicable, block the generator’s wheels to prevent sliding and shifting.
Outdoors only –
dangerous carbon
monoxide exhaust
WARNING: Carbon monoxide poisoning hazard
The exhaust from your generator contains carbon monoxide
(CO), a poisonous gas that can kill. You cannot smell it, see it,
or taste it. Carbon monoxide exhaust is given off whether you
are using gasoline, natural gas, or propane as the fuel source to
power the generator. Follow the directions below for choosing
a location to operate your generator in order to avoid carbon
monoxide poisoning.
The location you choose to operate the generator must be OUTDOORS
and away from all air intakes:
• Never run the generator inside any closed or semi-enclosed spaces (even if
outdoors), including homes, garages, basements, sheds, or boxes. These
spaces can trap poisonous gases, even if you run a fan or open windows.
• Place the generator so that the exhaust fumes will not be directed towards
people or building air intakes.
• Ensure that working, battery-operated or battery back-up carbon monoxide
alarms are used in any dwelling/structure that is in close proximity to the
running generator.
• Note that this generator is NOT designed or approved for use in vehicles
or marine applications. Never run the generator inside RVs or other
vehicles, on boats, or on pick-up truck beds.
WARNING:
Never attempt to attach ductwork to the muffler system to allow
for installation inside an enclosure. This could cause hot air
deflection, heat build-up, and increased exhaust back-pressure,
resulting in possible exhaust leakage or damage to the generator.

Installation / Initial Set-Up
17
Adequate cooling
ventilation The generator needs adequate, unobstructed flow of air to allow for proper cooling of engine and generator head.
WARNING:
Heat build-up from inadequate ventilation can result in fire,
posing a serious risk to nearby persons and structures.
• Situate so there is adequate clearance around generator to allow for
cooling airflow so that heat does not build up.
• Never place the generator immediately adjacent to a building or other
structure – allow at least a 7’ clearance.
• Do not run the generator in close proximity to other heat-generating
equipment, such as another generator. The combined heat that is
generated may raise air temperature in the immediate area and there will
not be adequate cooling ventilation.
• Do not allow debris to accumulate and block airflow.
• Do not operate with a tarp, blanket, or cover surrounding the generator.
No wet conditions Choose a location where the generator will NOT be exposed to rain,
snow, or direct sunlight. Exposure to water can cause electric shock.
You may operate the generator under an outdoor, canopy-like structure of
heat-resistant material that is open on all sides. Make sure that all parts of
canopy are at least 7’ from exhaust, and allow for adequate clearance above
generator so that heat does not build up.
Hot exhaust
clearance The exhaust gas from your generator is extremely hot and can cause combustible materials to catch on fire.
• Make sure your generator’s exhaust system is at least 7 feet from all
combustible materials and buildings/structures.
• Equip the engine with a spark arrestor if the generator will be used near
any ignitable forest, brush, or grassy land. (See the “Specifications”
section of this manual to determine if your generator is already equipped.)
Make sure you comply with applicable local, state, and federal codes.
• Keep a fire extinguisher rated “ABC” nearby. Keep it properly charged
and be familiar with its use.
Away from
dust/dirt Do not use the generator in extremely dusty or dirty conditions.
Excessive dust and dirt can cause premature failure of the machine.
Hearing
protection Generators can produce noise levels of up to 95 dB in close proximity, which can be dangerous to human hearing with prolonged exposure.
Hearing protection may be required for persons working within 15-20 feet of
the running generator for an extended period of time.
WARNING:
Never attempt to attach ductwork to the muffler system to lower
noise levels. This could cause hot air deflection, heat build-up,
and increased exhaust back-pressure, resulting in possible
exhaust leakage or damage to the generator.

Installation / Initial Set-Up
18
5. Grounding the generator
Always ensure the generator is properly grounded to prevent electrical shock.
You must always ground the generator by the following method when using the generator as a
portable electrical source:
1) Drive a ¾” or 1” copper pipe or rod into the ground close to the generator. The pipe/rod
must penetrate moist earth – the depth required will be dictated by local soil conditions.
Consult with an electrician.
2) Connect an approved ground clamp to the pipe.
3) Run a 10 gauge wire from the clamp to the generator grounding post located on the rear of
the generator head.
4) Do not connect the generator grounding post to a water pipe or a ground used by a radio
system.
If a licensed electrician installs the generator with a connection to your building’s electrical circuit
for use as a back-up power system, grounding may alternatively be completed through the
building’s grounding system. Ask your electrician. If the generator is not grounded through your
building’s electrical system, follow the procedure above.
WARNING:
Operating the generator when it is not properly grounded can result in electrical
shock.

Once you have set up your generator for use, it is time to start your generator. The following
are the procedures necessary for safe, successful operation of your generator.
Operation Procedures
1. General Safety Rules for Operation
2. Preparing for Operation
3. Starting the Engine
4. Checking Generator Output
5. Connecting Electrical Loads (Portable Power Generation)
6. Stopping
7. Storage & Exercise of Generator
Each of these procedures is discussed in detail below:
1. General safety rules for operation
Before starting the generator, review the following general safety rules for operation:
WARNING:
Failure to follow safety rules may result in serious injury or death to the
operator or bystanders.
• Know proper use/how to stop. Be thoroughly familiar with proper use of the equipment and all
generator controls, output receptacles, and connections. Know how to stop the generator quickly
if needed (see “Operation, Step 6 - Stopping the Engine”).
• Instruct operators. The generator owner must instruct all operators in safe generator set-up and
operation. Only trained adults should set up and operate the generator – Do not let children
operate.
• Intended use. Carefully read about and understand the intended use of this generator. Do not
use for other purposes, as unforeseen hazards or equipment damage may result.
• Under the influence. Never operate, or let anyone else operate, the generator while under the
influence of alcohol, drugs, or medication.
• Safety equipment / controls. Do not operate the generator unless all safety covers, guards, and
barriers are in place and in good working order, and all controls are properly adjusted for safe
operation.
• Damaged. Do not operate the generator with damaged, missing, or broken parts.
• Modifications. Do not modify the generator in any way. Modifications can create serious
safety hazards and will also void the warranty.
• Engine speed. Never attempt to modify the engine speed setting. The engine speed is preset at
3600 RPM for safe and optimal performance of the generator. If speed needs adjusting, it must
be done by factory-authorized personnel.
• External fuel sources. Never attempt to connect external gasoline/diesel sources in order to
increase engine run time. Larger tank at pressure or higher elevation will cause gasoline to leak
from carburetor during operation. Fire or explosion could result.

Operation (cont’d)
20
• Malfunction during operation. Immediately turn off the generator if any of the following
conditions arise during operation:
o Excessive change in engine speed, slow or fast
o Overheating in load connecting devices
o Sparking or arcs from generator
o Loss of electrical output
o Receptacle damage
o Engine misfire
o Excessive vibration
o Flame or smoke
o Abnormal noise
• Adjusting / repairing. Always turn off generator and remove spark plug(s) or spark plug
wire(s) before working on the generator to prevent accidental starting. Always discharge the
capacitor before working on the generator head to prevent electrical shock. (See Maintenance &
Repair section of this manual for instructions on how to do this.)
• Carbon monoxide poisoning. The running engine gives off carbon monoxide, a poisonous gas
that can kill you. You CANNOT smell it, see it, or taste it. Follow all instructions for site
selection and positioning the generator, and avoid inhaling the exhaust. If you start to feel sick,
dizzy, or weak while using the generator, shut off the engine and get to fresh air RIGHT AWAY.
See a doctor. You may have carbon monoxide poisoning.
• Other exhaust dangers. This product contains or emits chemicals known to the State of
California to cause cancer, birth defects or other reproductive harm. Avoid inhalation of
exhaust.
• Wet conditions. Do not operate the generator or handle any electrical equipment while standing
in water, while barefoot, while hands are wet or while in the rain or snow. Electric shock may
result.
• Ground fault circuit interrupter. Always use a ground fault circuit interrupter (GFCI)
protected extension cord (or outlet, if generator is equipped) in damp or highly electrical
conductive areas and on construction jobsites to prevent electrical shock.
• Avoid contact. Avoid contact with bare wires, terminals, connections, etc. while the unit is
running.
• Electric shock accident. If an electric shock accident occurs, immediately shut down the source
of electrical power. If this is not possible, attempt to free the victim from the live conductor.
Avoid direct contact with victim. Use a nonconducting implement, such as a dry rope or board,
to free the victim from the live conductor. Apply first aid and get immediate medical help.
• Smoking/sparks. Never smoke near the running generator, and never operate near sources of
sparks or flames.
• Hot muffler. Never touch hot muffler, hot exhaust manifold, or engine cooling fins. Exhaust
and engine parts can be very hot and will burn you.
• Moving parts. Keep hands, feet, and apparel away from drive belts, fans, and other moving
parts. Never remove any drive belt or fan guard while the unit is operating.
