Owner’s Manual
Instructions for Installation/Set-up, Operation, Servicing, & Storage
Portable, Outdoor Use-Only, Gasoline Generator
Can be used to power individual appliances plugged directly into the generator’s outlets, or as a back-up
connection to a building’s power supply (via a professionally installed UL-approved transfer switch).
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 at least 20 feet from the home, away from windows, vents and air intakes, to
allow proper ventilation. If you start to feel sick, dizzy, or weak while using the generator, shut off the engine and get to
fresh air RIGHT AWAY. 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 feet 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.
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.

Power Load Planning & Management
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

Power Load Planning & Management (cont’d)
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:
Greater of
Starting/Running Wattage
Light Bulbs (10 – 75 watt)
Air Conditioner, Window (10,000 BTU)
In this example, the generator must have a continuous output of at least 6750 watts 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
16
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.
6. Battery installation (electric start models only).
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 or damaged components, contact Product Support at 1-800-270-0810.
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
3. Set-up either as a BUILDING BACK-UP or PORTABLE Power Source
This generator is designed to provide up to its rated amount 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 an 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.
