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 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’ 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.

Power Load Planning & Management

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:

Greater of Starting/Running

Total

1800 W

2100 W

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:

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 or damaged components, contact Product Support at 1-800-270-0810.

Installation / Initial Set-Up (cont’d)

3. Set-up either as a BUILDING BACK-UP or PORTABLE Power Source

This generator is designed to provide up to 2700W 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.

Contact a licensed electrician to install a UL-approved transfer switch if

Using as a

you want to use your generator as a back-up power source for a building.

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.

Download from Www.Somanuals.com. All Manuals Search And Download.

Installation / Initial Set-Up (cont’d)

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.

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.

Using as a

Portable Power

Source

There are two identical electrical outlets on the generator. Each is a 120 Volt,

20 Amp, duplex straight-blade receptacle (NEMA 5-20R duplex receptacle

compatible with NEMA 5-20P or 5-15P mating plugs).

(2) NEMA

5-20R duplex

(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.

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 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 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.

 Never place the generator immediately adjacent to a building or other

structure – allow at least 20 feet clearance.

 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:

Installation / Initial Set-Up (cont’d)

Adequate cooling The generator needs adequate, unobstructed flow of air to allow for

ventilation

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 large objects or

structures – 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 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

Hearing

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.

protection

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 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)

 Malfunction during operation. Immediately turn off the generator if any of the following conditions

arise during operation:

Excessive change in engine speed, slow or fast

Overheating in load connecting devices

Sparking or arcs from generator

Loss of electrical output

Receptacle damage

Engine misfire

Excessive vibration

Flame or smoke

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.

Operation (cont’d)

Static electricity and filling the gasoline tank:

Static electricity can initiate from ungrounded gasoline tanks or containers, from flowing gasoline, and

from persons carrying a static electric charge

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 charge 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. A person dispensing the gasoline can carry a static electric charge on their body, typically

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.

2. Preparing for Operation

Position

generator

Position generator in accordance with the instructions given in

“Installation & Initial Set-up, Step 4: Select a Suitable Site” of this

manual.

Operate outside only, on dry, level ground with at least 20 feet from the home,

away from windows, vents and air intakes, to allow proper ventilation.

WARNING: Carbon monoxide poisoning hazard

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 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, garages, basements, sheds,

boxes, pick-up truck beds, RVs, or boats. These spaces can trap

poisonous gases, EVEN if you run a fan or open windows. Carbon

monoxide exhaust is given off whether you are using gasoline, natural

gas, or propane to power the generator.

Ground

generator

Make sure the generator is grounded in accordance with instruction given

in “Installation & Initial Set-up, Step 5: Grounding the Generator” of

this manual.

Operation (cont’d)

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

container to transfer gas to the generator’s tank.



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.

Operation (cont’d)



Keep nozzle in contact with portable container while filling. Manually

control the flow of gasoline; do NOT use the nozzle’s lock-open

device.

A portable container made of metal or conductive plastic is preferred

because it dissipates charge to ground more readily.

5) Clean up gasoline spills /splashes immediately.



If possible, move the generator away from spilled gasoline on the ground.

Wipe up spilled gasoline, and wait 5 minutes for excess gasoline to evaporate

before starting engine.



Gasoline soaked rags are flammable and should be disposed of properly.

If gasoline is spilled on your skin or clothes, change clothes and wash skin

immediately.

6) Replace gasoline cap securely before starting engine.

7) Store extra gasoline in a cool, dry place in an UL-approved, tightly sealed

container.

IMPORTANT:

For continuous operation, be prepared to check and refuel the engine on a

regular basis. A tank of gasoline should last about 2.3 hours under 50%

load.

Inspect Fuel

System / Check

for Leaks

Inspect fuel system & check for leaks BEFORE starting generator.

Do not start generator until all needed repairs have been completed.

WARNING: Fuel leak hazard

Gasoline is highly explosive and fuel leaks can result in fire or

explosions. You can be burned and seriously injured if the fuel system is

not properly hooked up or there is a fuel leak when you start the engine.

Inspect the entire fuel system.

Look for:

 signs of leaks or deterioration,

 chafed or spongy fuel hose,

 loose connections,

 loose or missing fuel hose clamps,

 a damaged gasoline tank, or

 a defective gasoline shut-off valve.

1) Disconnect all loads to the generator.

2) Adjust choke:

a) To start a cold engine, pull the choke rod to the CLOSED position.

b) To restart a warm engine:

i) If the engine has run out of fuel, pull choke rode to the CLOSED position after refueling.

ii) If the engine has not run out of fuel, leave the choke rod in the OPEN position.

3) Start the engine:

a) Move the ignition switch lever (red) to the ON position.

b) Pull the starter grip lightly until you feel resistance, then pull the starter cord out briskly and

rapidly. Allow starter cord to return slowly.

4) If the choke rod was pulled to the CLOSED position to start the engine, push it to the OPEN

position as soon as the engine warms up enough to run smoothly.

5) Under long, continuous-run operating conditions, be prepared to:

a) Check and refuel the engine on a regular basis. A tank of gas should last about 2.3 hours

under a 50% load. See engine owner’s manual for more detail.

WARNING:

A running engine is hot enough to ignite fuel. Never add fuel or

remove gas cap if engine is running or still hot. Let cool at least

2 minutes.

b) Check engine oil level each time you refuel.

c) Change oil after the first 20 operating hours, and at least every

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.

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.

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.

NOTE:

Slight variation in

voltage/speed with

changing electrical

loads

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.

Safety – Installation & Set-up

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 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 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 power the generator.



No vehicle/marine use. 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.

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

Summary of Important Safety Information for Operation (cont’d)

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 back feed 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.



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.
