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:
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/buildin gs (bat t er y -o perat ed , or plug-in with battery backup).
• 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.
• 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.

Power Load Planning & Management
NEVER exceed the rated wattage capacity of your generator.
WARNING
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 poweringsimultaneously.
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 1below.
Guidance for starting wattages is provided in the table’s footnotes.

Running
Watts Device
Running
Watts
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
Starting/Running Wattage
Greater of
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.
STAGGERING LOADS
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
There are a number of important steps required to set up your generator for initial use. These
steps are:
Each of these steps is discussed in detail below:
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.
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

3. Set-up either as a BUILDING BACK-UP or PORTABLE Power Source
This generator is designed to provide up to 8000Wof 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

that have been chosen as critical to operate during a power outage.
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.)
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 520R duplex receptacle compatible with NEMA 5-20P or 5-15P mating
plugs).
3. One 120 Volt, 15 Amp duplex straight-blade receptacle (NEMA 5-

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.
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.
16
Page 17
Installation / Initial Set-Up
• 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.

dust/dirt
Hearing
protection
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.
Do not use the generator in extremely dusty or dirty conditions.
Excessive dust and dirt can cause premature failure of the machine.
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.

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 ope rators. 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 spee d . 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 factoryauthorized 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.

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.
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.
Always discharge the capacitor before working

Static electricity and filling the gasoline tank:
Static electricity can initiate from ungrounded gasoline tanks or containers, from flowing gasoline, and
Static electricity can explosively ignite gasoline vapors that are present during the fueling process, resulting
in serious burns to nearby persons. To avoid static electricity while fueling, certain steps must be followed
before and during the fueling process in order to minimize and safely dissipate static charge build-up:
• Touch a grounded metal object before starting. Always dissipate static charg e from your body
before beginning the fueling process by touching a grounded metal object at a safe distance away from
fuel sources.
• Use a portable container to fill tank. Never fill the generator’s gas tank directly from the fuel pump –
the generator’s tank is not grounded and the high velocity flow of gasoline from a fuel pump can cause
static electric build-up. Use an approved portable container to transfer gasoline to the generator’s
tank.
• Fill container on the ground. Never fill the portable gas container while it is sitting inside a vehicle,
trailer, trunk, or pick-up truck bed. ALWAYS place container on the ground to be filled.
• Keep nozzle in contact with container. Keep nozzle in contact with the portable container at all times
while filling. Manually control the flow of gasoline; do NOT use the nozzle’s lock-open device.
• Use a portable container made of metal or conductive plastic. It will dissipate charge to ground more
readily.
About static electricity and fueling
Many common objects can accumulate and retain a static electric charge. Objects made of non-conductive
materials (e.g. plastics) easily accumulate and retain static electric charge, as can objects made of conductive
material (e.g. metal, water) if they are not electrically grounded. The static electric charge on an object, such
as a human body or plastic fuel tank/container, can reach as high as several thousand volts!
A static electric spark can be generated if the static electric charge stored on an object “jumps” to another,
less charged object. Such a spark can ignite invisible gasoline vapors that are present during fueling
situations.
Typical sources of static electric hazards during fueling
The following objects can accumulate a static electric charge and cause an ignition spark in typical fueling
situations:
1) Ungrounded tanks/containers. Any ungrounded fuel tank or container can accumulate a static electric
charge as a result of contact with other objects or friction during transportation. This static electricity
can discharge as a spark to the grounded gasoline dispenser nozzle, as the nozzle is first brought close to
the tank/container at the beginning of the fueling process.
2) Flowing gasoline. Most people are not aware that gasoline accumulates static electric charge while
flowing through a hose or pipe. This charge then transfers to and accumulates in the gas tank or container
that is being filled. The total amount of charge accumulation depends on the amount of gas pumped into
the container, the speed with which it is pumped, and whether or not the tank/container is grounded. If
sufficient static electric charge accumulates in the fuel tank or container during the fueling process, the
tank/container may discharge a spark to the grounded gasoline dispenser nozzle.
3) Persons
resulting from contact with their car seat or electronics. The static electricity can discharge as a spark
between that person’s hand and either the grounded dispenser nozzle or the fuel tank opening.
. A person dispensing the gasoline can carry a static electric charge on their body, typically
from persons carrying a static electric charge

WARNING: Gasoline fire/explosion hazard
Gasoline is highly flammable and explosive. Heat, sparks, and flames
can ignite gasoline vapors, which can become widespread during fueling.
A flash fire and/or explosion could result and cause serious injury or
death. Use extreme care when handling gasoline. Carefully follow all
the instructions in this section to avoid the following conditions which
could result in gasoline ignition:
• gas vapor collection inside enclosures
• static electric sparks
• sparks from electric wiring, batteries, or running engines
• sources of heat (such as a hot engine or exhaust)
• open flames, including pilot lights
1) Before starting, review the following general safety precautions for fueling:
a) Never pump gasoline directly into the generator’s gas tank at a gas station –
high velocity flow from the pump could result in a static electric build-up
in the generator’s tank. Always use a portable container to fill the tank.
See warning box about static electric spark hazards below.
b) Fill gasoline tank OUTDOORS – never indoors.
c) Stay away from all sources of heat, sparks, and flames. Do not smoke.
2) Turn generator engine off and allow to cool for at least two minutes before
removing gas cap.
Note: A running or still-hot engine is hot enough to ignite fuel.
3) Remove generator gasoline cap.
4) Add gasoline through the fill opening:
- Use only a UL-approved portable gasoline container to transfer the gasoline
to the generator’s tank. Follow the safety warning and instructions below
for avoiding static electric sparking.
- Do NOT overfill the gasoline tank. Allow at least 1/2” of empty space
below the fill neck to allow for fuel expansion.
WARNING: Static electric spark hazard
A static electric spark can explosively ignite gasoline vapor, resulting in a
flash fire that could cause serious injury or death.
To avoid static electric sparking while filling the gasoline tank, the
following steps must be followed to minimize and safely dissipate static
electric charge build-up before and during the fueling process
• Always dissipate static charge from your body before beginning the
fueling process by touching a grounded metal object at a safe distance
from fuel sources.
• Never fill the generator’s gas tank directly from the fuel pump – the
generator’s tank is not grounded and high velocity flow from the pump
can cause static electricity build-up. Use an approved portable

Operation (cont’d)
4. Checking Generator Output
Although the speed of the engine was carefully adjusted at the factory so that the generator
produces the proper voltage and frequency, output voltage should be checked periodically to
ensure the generator is working properly before connecting loads to the generator.
WARNING:
The generator must be run at the correct speed in order to produce the
proper electrical voltage and frequency. Failure to do so could result in
damage to equipment powered by the generator and possible injury to the
individual.
Output voltage should be checked with a portable voltage meter:
1. Start engine and allow to warm up for five minutes. Do not connect any loads.
2. Use voltage meter to check output voltage
at the generator’s outlets/receptacles.
3. Measured voltage should be within the
following ranges:
a. 120V +/- 10% at 120V receptacles.
b. 240V +/- 10% at 240V receptacles.
4. If measured voltage is not within the specified range, have generator adjusted by factory
authorized personnel. Do not attempt to adjust the engine speed yourself.
NOTE:
Slight variation in
voltage/speed with
changing electrical
loads
All engines have a tendency to slow down when a load is applied. When
electrical loads are connected to the generator, the engine is more heavily
loaded and as a result the speed drops slightly.
This slight decrease in speed, together with the voltage drop within the
generator itself, results in a slightly lower voltage when the generator is
loaded to its full capacity than when it is running with no load.
Additionally, there may be small brief surges and drops in voltage as motors
connected to the generator cycle on or off.
The slight variation has no appreciable effect in the operation of motors,
lights, and most appliances.

5. Connecting Loads
You will want to be careful when connecting loads so as not to overload the generator, especially if
you are powering devices with motors that require a higher starting power load.
Instructions are provided below for connecting loads when you are using the generator:
o As a portable power source
o Connected to a building as a back-up power source
WARNING:
Do not overload generator. Make sure that combined starting and running loads do
not exceed rated capacity of generator. Overloading the generator can cause damage
to the generator and attached electrical devices, and may result in fire.
Using as a
Portable Power
Source
Using as a
Back-up Power
Source for a
Building
Stop the engine using the following steps:
1. Disconnect all loads to the generator.
Connect electrical loads one at a time according to the following
instructions:
1. Allow engine to reach operating speed by allowing it to warm up for
approximately 5 minutes before connecting electrical devices.
2. After engine is warmed up, begin by connecting the items that require
the highest wattage first. The recommended sequence is as follows:
a. Connect items with motors such as refrigerators, freezers, air
conditioners, or small hand tools, one at a time. Let each motor
stabilize before connecting the next device.
b. Connect any lights you are planning on powering.
c. Connect voltage sensitive equipment such as electronics via surge
protectors. Plug devices such as TV’s, computers, and microwaves
into a UL listed voltage surge protector, then plug the surge
protector into the generator.
Each transfer switch installation will be unique.
Proper instructions for how to safely bring the generator online with the
building’s electrical system should be provided by the installing electrician,
who should also provide personal instruction to the owner/operator.
Failure to follow the proper procedure as provided by the electrician could
expose persons to the hazards noted above.

Summary of Important Safety Information for Operation (cont’d)
Installation / Initial Set-up Safety
• Dry, level surface. Situate generator on a dry, firm, level surface. Ensure generator sits level and will not
slide or shift during operation. Block wheels if applicable.
• Operate OUTSIDE only – dangerous carbon monoxide exhaust! Generators give off carbon monoxide
exhaust, a poisonous gas that can kill. You CANNOT smell it, see it, or taste it. ONLY run generator
OUTDOORS and away from building air intakes. NEVER run generator inside homes, garages, sheds, or
other semi-enclosed spaces. These spaces can trap poisonous gases, EVEN if you run a fan or open windows.
Carbon monoxide is given off whether you are using gasoline, natural gas, or propane to powe r the generator.
• No vehicle/marine use. This generato r is N OT desi gned 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.
• Cooling ventilation. The generator needs adequate, unobstructed flow of air to allow for proper cooling of
engine and generator head. Situate so there is adequate clearance around generator to allow for cooling
airflow. Do not allow debris to accumulate and block airflow.
• Grounding. Always ensure generator is properly grounded to prevent electrical shock. This generator is
equipped with a grounding post. Always complete the grounding path from the generator to a copper pipe/rod
driven into moist earth to a sufficient depth. Check with an electrician for local grounding requirements. If a
licensed electrician installs the generator with a connection to your building’s electrical circuit for use as a
standby power system, grounding will be complete through the building’s grounding system.
• Isolate connection to building’s electrical circuit. 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 an UL-approved transfer switch installed by a licensed electrician in compliance with all
applicable local building and electrical codes. If the generator is not isolated from the utility power system by
such means, generator output will backfeed into the utility power grid. This may result in injury or death to
utility power workers or others who contact the lines during a power outage. It may also cause the generator
to explode or cause fires when utility power is restored.
• Wet conditions. Water conducts electricity. Do not operate generator where it is wet. Operate on a dry
surface under an open, canopy-like structure.
• CO alarms. 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.
• Hot exhaust - fires. Exhaust from engine can be extremely hot and cause fire. Position muffler at least 7’
from combustible objects during operation.
• Spark arrestor. Equip engine with a spark arrestor if 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.
• Fire extinguisher. Keep a fire extinguisher rated “ABC” by the National Fire Protection Association nearby.
Keep it properly charged and be familiar with its use.

Gasoline Safety
Gasoline is highly flammable and explosive. You can be burned or seriously injured when handling fuel. Use
extreme care when handling:
• Fuel outdoors. Fill fuel tank outdoors – never indoors. Gasoline vapors can ignite if they collect inside an
enclosure. Explosion can result.
• Use approved container. Never pump fuel directly into engine at gas station. Static charge can build and
ignite fuel. Use an UL approved fuel container to transfer gas to the engine.
• Running / hot engine. A running engine is hot enough to ignite fuel. Never add fuel or remove gas cap if
engine is running or still hot. Stop the engine and allow to cool at least two minutes before adding fuel.
• Heat / flames / sparks. Stay away from sources of heat, flame, or sparks while adding fuel.
• Don’t overfill . DO NOT overfill the gas tank. Allow at least 1/2” of empty space below the fill neck to allow
for fuel expansion.
• Replace cap. Replace gas cap securely before starting engine.
• Spills. Clean up fuel spills immediately. Move generator away from spilled fuel on the ground. Wipe fuel off
engine and wait 5 minutes for excess fuel to evaporate before starting engine. Gas soaked rags should be
disposed of properly.
• On skin / clothes. If gasoline is spilled on your skin or clothes, change clothes and wash skin immediately.
• Inspect fuel system. Check fuel system on a regular basis. Look for signs of leaks, deterioration, chafed or
spongy fuel hose, loose or missing fuel hose clamps, damaged fuel tank, or a defective fuel shut-off valve. Do
not start generator until needed repairs have been completed.
• Gasoline storage. Store gasoline in a cool, dry place in an UL-approved, tightly sealed container.
Safety – During Use
