building’s power supply (via a professionally installed UL-approved transfer switch.

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.

• Carbon monoxide is given off whether you are using gasoline, natural gas, or propane to power the generator.

• 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.

• LPG/NG hook-ups must be completed by a certified gas technician and comply with all federal and local requirements.

• 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 transfer switch and/or NG/LPG hook-ups, if they will be used.

See the “Installation/Initial Set-Up” section for more information about these requirements.

About Your Generator

Thank you for purchasing your NorthStar portable generator!

About Your Generator

This engine-driven, portable generator is designed to provide up to 8,000 Watts of

electrical power (6,600 watts continuous, 8,000 watts surge).

It can supply power:

1. As a portable power source. You can plug appliances directly into the generator’s

electrical outlets.

2. As a back-up, standby power source for a building. A licensed electrician can connect

the generator to your building’s electrical system via the installation of an UL-approved

transfer switch. (See the “Installation & Initial Set-up” section of this manual to learn

more about specific requirements and precautions relating to wiring the generator to your

building’s electrical system.)

You must select a generator adequately sized for your power needs. You need to

determine the power needs of all the appliances/tools you wish to power at the same time and

choose a generator rated to provide at least that power level. See the “Power Load Planning &

Management” section of this manual to determine your specific power load requirements and

then compare them to this generator’s rated capacity. You must not overload the generator.

Overloading will cause damage to the generator and attached electrical devices, and may also

result in fire.

You can power this generator with gasoline, natural gas (NG), or propane (LP) gas. The

generator is designed so that it is easy to switch between fuel sources. However, there are

special initial hook-up requirements for natural gas and propane. See the “Specifications”

section of this manual with regard to specific gas flow and pressure requirements. In addition,

note the following:

♦ Natural gas. The standard delivery pressure provided to your building by your utility

company may not match the requirements of your generator.

a) If your standard delivery pressure is higher than allowable for this generator, you

may need to have a pressure-reducing regulator installed. (Note: The regulator

supplied with this generator is NOT a pressure-reducing regulator).

b) If your standard delivery pressure is lower than allowable for this generator, you

will need changes to your natural gas service to elevate the delivery pressure.

ALL natural gas hook-ups must be completed by trained personnel from your natural gas

utility company and inspected as required by your local building code.

♦ Propane (LP). You will need a minimum 100 lb. LPG gas tank to run this generator – the

vaporization rate is insufficient with smaller tank sizes. A qualified propane gas

technician must set up the valve and hose connection between the propane tank and

generator in accordance with all local regulations and electric code.

See the “Installation / Initial Set-Up: Step 3” section of this manual for more detailed

information.

Be sure to read about site selection and grounding requirements for running this

generator. More detailed information can be found in the “Installation & Initial Set-up, Steps

5 & 6” of this manual.

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.

3. Gas Hook-up Installation for Natural Gas or LPG (if needed)

You can power this generator with gasoline, natural gas (NG), or propane (LP) gas. The generator

is designed so that it is easy to switch between fuel sources. However, there are special initial

hook-up requirements for natural gas and propane:

WARNING:

If you choose to operate the generator on NG or LPG, you must have the fuel line system

installed by a certified gas technician.

Specific requirements for each type of hook-up are given below:

Natural Gas (NG) Contact your gas utility company for installation of a natural gas hook-

Hook-up

up for the generator.

WARNING:

Natural gas is a highly explosive gas. All natural gas hook-ups must

be completed by trained personnel from your natural gas utility

company and inspected as required by your local building code.

♦ This product is designed to operate on NG at a gas pressure range of 4 to

6 ounces per square inch (7”-11” of water column) and requires a

minimum NG flow rate of 3.25 CFM.

♦ The standard gas pressure normally delivered to your building by your

utility company may be higher or lower than the required 4-6 ounces per

square inch (7”-11” of water column):

o If your standard delivery pressure exceeds 4-6 ounces per square

inch (7”-11” water column), you will need a pressure-reducing

regulator installed. Excessive gas pressure will permanently

damage this product and void the warranty if the generator is not

installed correctly with a pressure-reducing regulator as needed.

Note: The regulator supplied with this product is NOT a

pressure-reducing regulator, but one can be supplied

and installed by your gas utility technician at the time

of fuel system hook-up.

o If your standard delivery pressure is lower than 4-6 ounces per

square inch (7”-11” water column), you will need changes to your

natural gas service to provide elevated delivery pressure. In

addition you will need to have a pressure-reducing devices installed

for your other natural gas appliances.

Propane (LPG)

Hook-up

Contact your local propane supplier to install a propane fuel system for

the generator.

WARNING:

LPG is a highly explosive gas. A qualified propane technician must

make the valve and hose connection between the propane tank and

generator in accordance with all local regulations and electrical codes.

All LPG hook-ups should be completed by trained personnel from

propane supplier and inspected as required by your local building

code.

Installation / Initial Set-Up

♦ This product is designed to operate at an LPG gas pressure range of 7” to

11” of water column and requires a minimum LPG gas flow rate of 9.33

lb/hr, 2.2 Gal/hr, or 201,718 BTU/hr.

Note: All gas cylinders produce gas pressure in excess of 11” water

column. Introduction of gas pressure into the generator in

excess of 11” water column will permanently damage this

product and void the warranty. You will need a pressure-

reducing regulator installed as part of your LP gas fuel system.

♦ You will need a minimum 100 lb. LPG gas tank to operate the

generator.

This generator will not work with 20-lb gas cylinders used in gas grills

and recreational equipment, or 40-lb gas cylinders used in forklifts and

tractors. These smaller gas tanks do not have a sufficient vaporization

rate to run the generator.

Some installations may require tanks even larger than 100-lb as a result

of low surrounding air temperature and other appliances drawing fuel

Installation / Initial Set-Up

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

This generator is designed to provide up to 8,000W 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

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

Back-up Power

Source for a

Building

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.

Installation / Initial Set-Up

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.

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 7 - 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.

generator OUTDOORS and away from air intakes. 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.

Using a funnel, add oil up to the FULL mark on the dip stick with the

recommended oil type for your engine and expected ambient conditions.

(See engine Owner’s Manual for oil type and capacity, and more detailed oil

check/fill instructions.)

WARNING: Burn hazard

Never open oil port while engine is running. Hot oil can spray over

face and body.

Notes:

o Low oil shutdown feature prevents the generator from starting without

sufficient oil.

o Engine is shipped without oil. You must add oil before first use.

IMPORTANT:

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

• Check engine oil level every time you refuel the engine if using

gasoline, or every 24 operating hours if using NG/LPG.

• Change oil after the first 20 operating hours, and at least every 100

operating hours thereafter, or as directed in engine owner’s manual.

Operation (cont’d)

Fill gasoline tank

(if using gasoline)

Check the gasoline level in the generator’s tank if you will be operating

the generator on gasoline.

If needed, fill tank with fresh unleaded gasoline from a portable

container, after first reading the warnings and instructions below.

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:

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

Operation (cont’d)

•

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.

Keep nozzle in contact with portable container while filling.

Manually control the flow of gasoline; do NOT use 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 4 hours under

100% load, and about 8 hours under 50% load.

Propane (LPG):

1) Make sure the fuel hose is securely connected to the propane tank

regulator on one end, and the ¾” NPT gas inlet on the generator base on

the other end.

Start LPG/NG

supply

(if using)

2) Open the propane tank main valve.

3) Check ¾” NPT gas inlet connection for leaks each time you connect. Use

the leak test method described below.

Natural Gas:

1) Make sure the gas line is securely connected to the ¾” inlet on the

generator base.

2) Open line valve, if gas line is so equipped.

3) Check ¾” NPT gas inlet connection for leaks each time you connect.

Operation (cont’d)

Inspect Fuel

Inspect fuel system & check for leaks BEFORE starting generator.

System / Check for Do not start generator until all needed repairs have been completed.

Leaks

WARNING: Fuel leak hazard

Gasoline, LP gas (propane) and NG (natural gas) are 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.

1) 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.

2) If you are using LPG or NG, check for leaks after opening supply valve:

a) Leak test method. Test for leaks on a regular basis by applying a

soap and water solution over pipes, hoses, and connections. Soap

bubbles will form if there is a leak. Use this method to test after each

reconnection to NG/LPG supply (for example, after moving the

generator), and on a regular basis thereafter. This method will help

you detect small leaks.

b) Also beware of gas odor. Both LP and NG have an odorant added

(rotten egg/sulfur smell) that will aid in the detection of more

dangerous quantities of leaking gas. Note:

• Natural gas. Natural gas is lighter than air and tends to collect in

high areas.

• LP gas (propane). LP gas is heavier than air and tends to settle in

low areas. Smell next to floor for gas.

If you smell gas, DO NOT start engine! DO NOT light a match. DO NOT

flip on an electrical switch. If possible, shut off LPG or NG

supply. Exit area immediately and call gas supplier or fire department.

Personal Protection 1) Hearing can be damaged from prolonged, close-range exposure to the

type of noise produced by this generator. The use of ear plugs or other

hearing protection device is recommended for persons working within

15-20 feet of the running generator for an extended period of time.

2) Loose or dangling apparel can become entangled in moving parts. Metal

jewelry can conduct electricity. Never wear jewelry or loose-fitting

clothing when starting or operating the generator.

3. Starting the Engine

After you have completed the pre-start checklist procedures, you are ready to start the engine.

The following directions detail how to start the engine with either LP/NG or Gasoline as the fuel

source:

Using LP/NG

To start engine using LP or Natural Gas:

WARNING:

DO NOT start engine if you smell gas. Exit area immediately

and call gas supplier or fire department. If possible, shut off

gas supply.

1) Disconnect all loads to the generator.

2) Flip fuel selector switch to the LP/NG position.

3) Start the engine:

a) Using electric start -

Turn the engine key switch to the START position and hold it there until

the engine starts. When the engine starts, release the key, allowing it to

return to the ON position.

b) Using recoil start –

Turn the engine key switch to the ON position. Pull the starter grip lightly

until you feel resistance, then pull the starter cord out briskly and rapidly.

Allow starter cord to return slowly.

Note: You must have the battery hooked up for recoil starting when

using LP/NG. The LP/NG fuel system requires a battery to function.

4) It may be necessary to momentarily depress the primer button while

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:

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.

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.

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 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

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.

•

Natural gas hook-up. Always consult with your gas utility company to determine installation requirements

for a natural gas hook-up. In order to safely operate your generator, you may need either a higher or lower

pressure than the standard delivery pressure provided to your building. You may need a pressure reducing

regulator, or you may need elevated delivery pressure which would require changes to your natural gas

service. All natural gas generator hook-ups should be completed by trained personnel from your natural gas

utility company and inspected as required by you local building code.

LPG hook-up. A qualified propane gas technician must set up the valve and hose connection between the

propane tank and generator in accordance with all local regulations and electric code. Check with your local

propane gas supplier.

•

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.

Propane & Natural Gas Safety

LP gas (propane) and natural gas are highly flammable and explosive. Even the slightest spark can ignite these

fuels. 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.

•

Initial hook-up by qualified personnel. Initial hook-up must be completed by qualified personnel from your

natural gas company or propane supplier and inspected per local code.

•

Inspect regularly. Inspect fuel system regularly for leaks. Do not start generator until leaks are repaired.

Smell for gas before starting the generator:

•

Natural gas. Natural gas is lighter than air and tends to collect in high areas. After opening NG line

supply, smell for gas BEFORE starting engine.

•

LP gas (propane). LP gas is heavier than air and tends to settle in low areas. After opening propane

tank valve, smell next to floor for gas BEFORE starting engine.

If you do smell gas, DO NOT start engine. DO NOT light a match. DO NOT flip on an electrical switch. Exit

area immediately and call gas supplier or fire department. If possible shut off gas supply.

Stabilize before connecting loads. Start generator and let engine stabilize before connecting electrical loads.

Do not overload. Do not overload the generator. Make sure that combined starting and running loads do not

exceed rated capacity of generator or damage will result.

•

Protect sensitive electronics. Some electronic equipment, such as computers and audio/video equipment,

can be damaged by small fluctuations in the flow of power. Use a surge suppressor for any voltage-sensitive

electronic equipment you will be powering with the generator.

•

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.

•

Electrical cords. Use only UL-listed, outdoor-rated, three prong extension cords of the proper size. All

extension and appliance cords must be in good condition and not worn, bare, frayed, or otherwise damaged.

Use of inadequate or damaged electric cords can cause electric shock or fire.

•

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.

•

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.

•

Refueling. DO NOT refuel the engine until it has cooled at least two minutes.

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.

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

Safety – After use

Cool engine before storing. Let engine cool for at least five minutes before storing. A hot engine can be a

fire hazard.

Shut off fuel supply. Make sure gasoline shut-off valve is in the OFF position. Turn off propane tank valve

or shut NG line valve, as applicable.

•

Prevent accidental starting. When generator is not in use, remove key from starter (key start engines) and

secure in a safe location, or remove spark plug(s) in order to ensure that generator cannot be started in a

storage location or by untrained persons.

Storage location. Store the generator in a dry location away from sources of heat, open flames, sparks or

pilot lights – such as water heaters, space heaters, furnaces, clothes dryers, or other gas appliances – EVEN IF

the generator’s gas tank is empty. Residual gasoline could ignite.

•

Exercise regularly. Exercise generator every four weeks to dry out moisture that accumulates in the

windings. If generator cannot be exercised on a regular basis, prepare generator for long term storage.

Periodic maintenance. Perform periodic maintenance as directed in this manual to keep the generator in safe

working condition.

Safety - Inspection/Maintenance

Inspect and maintain your generator on a regular basis and repair as needed to keep it in safe working condition:

•

Turn off generator. Always turn off generator and remove spark plug(s) or spark plug wire(s) before

working on the engine or generator to prevent accidental starting.

•

Discharge capacitor. When the generator is shut down, the capacitor may maintain a charge. Always

discharge the capacitor before working on the generator head to prevent electrical shock.

Replace guards / shields. Make sure all guards and shields are replaced after servicing the generator.

Replacement parts. If a part needs replacement, only use parts that meet the manufacturer’s specifications.

Replacement parts that do not meet specifications may result in a safety hazard or poor operation of the

generator and will void the warranty.
