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

2. electrical outlets.

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:

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.

12

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. Getting gas hook-ups installed if natural gas or LP gas will be used as a fuel source.

4. 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.

5. Selecting a site for using the generator.

6. Grounding.

7. Battery installation (electric start models only).

Each of these steps is discussed in detail below:

1. Unpacking & Delivery Inspection

You should inspect the generator immediately after you receive delivery.

See the “Machine Component Identification” section of this manual for a diagram of the generator and its components.

• If you have missing components, contact Product Support at 1-800-270-0810.

• If you have damaged components, contact the freight company that delivered the unit and file a claim.

2. Planning the Power Load

Plan your power load so that you do not exceed the generator’s rated capacity.

See the “Power Load Planning & Management” section of this manual to review how to plan and manage power loads for the generator.

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)

Hook-up

Propane (LPG)

Hook-up

Contact your gas utility company for installation of a natural gas hookup 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.

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.

14


♦ 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 pressurereducing 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 from the same tank.

15


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

Back-up Power

Source for a

Building

Contact a licensed electrician to install a UL-approved transfer switch if you want to use your generator as a back-up power source for a building.

What does a transfer switch do? It: a) Safely connects the generator to your building’s electrical system by isolating your generator from your utility company’s power lines,

AND b) Connects your generator to a critical subset of your building’s circuits that are needed for emergency power needs.

If your generator will be connected to your building’s electrical system, it

MUST ALWAYS be isolated from the utility power grid with a UL-approved

transfer switch installed by a licensed electrician in compliance with all applicable building and electrical codes, and in accordance with guidelines supplied by your power company.

DANGER:

A transfer switch must be installed in order to isolate your generator from the utility power grid. If your generator is

NOT properly isolated from the utility system, serious hazards will arise:

♦ When your generator is running, it’s output will back feed into the utility power line and transformer that are normally used to provide you with power. The transformer will step up the current to the normal line voltage. An unsuspecting utility line worker working on what he thinks is a deactivated line could be electrocuted.

♦ If your generator is connected (running or not) when utility power is restored, your generator will be destroyed.

It could also explode or cause fire.

In addition to isolating your generator from the utility system, the transfer switch connects your generator to a limited set of circuits in your building that have been chosen as critical to operate during a power outage.

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 5-

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

3. One 120 Volt, 15 Amp duplex straight-blade receptacle (NEMA 5-

15R receptacle compatible with NEMA 5-15P mating plug)/

5. Select a Suitable Site

Before using the generator, you must select a suitable OUTDOOR location for installation and operation. This location should meet all of the criteria listed below.

WARNING:

You must choose a suitable site for operating your generator to avoid equipment damage and/or injury and possible death from carbon monoxide poisoning, electric shock, or fire.

Choose a site that meets all of the criteria specified.

Dry, level surface

The generator should be positioned on a dry, firm, level surface.

Ensure that the generator sits level and will not slide or shift during operation.

Outdoors only – dangerous carbon monoxide exhaust

If applicable, block the generator’s wheels to prevent sliding and shifting.

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.

• Situate so there is adequate clearance around generator to allow for cooling airflow so that heat does not build up.

19


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

Hot exhaust clearance

generator so that heat does not build up.

The exhaust gas from your generator is extremely hot and can cause combustible materials to catch on fire.

• Make sure your generator’s exhaust system is at least 7 feet from all combustible materials and buildings/structures.

• Equip the engine with a spark arrestor if the generator will be used near any ignitable forest, brush, or grassy land. (See the “Specifications” section of this manual to determine if your generator is already equipped.)

Make sure you comply with applicable local, state, and federal codes.

• Keep a fire extinguisher rated “ABC” nearby. Keep it properly charged and be familiar with its use.

Away from dust/dirt

• 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.

Hearing protection

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.

6. Grounding the generator

Always ensure the generator is properly grounded to prevent electrical shock.

You must always ground the generator by the following method when using the generator as a portable electrical source:

1) Drive a ¾” or 1” copper pipe or rod into the ground close to the generator. The pipe/rod must penetrate moist earth – the depth required will be dictated by local soil conditions.

Consult with an electrician.

2) Connect an approved ground clamp to the pipe.

3) Run a 10 gauge wire from the clamp to the generator grounding post located on the rear of the generator head.

4) Do not connect the generator grounding post to a water pipe or a ground used by a radio system.

Ask your electrician. If the generator is not grounded through your building’s electrical system, follow the procedure above.

WARNING:

Operating the generator when it is not properly grounded can result in electrical shock.

21


7. Battery Installation

Your generator’s engine is equipped with an electric starter which requires the installation of a 12volt lawn tractor size battery (Group U1). See the “Specifications” section of this manual for more specific battery requirements for this generator model, such as minimum amperage or CCA rating.

The battery is to be supplied by the customer and should be installed in the protective battery box located near the engine. Follow the instructions detailed below for connecting and disconnecting the battery.

WARNING: Battery hazards

Batteries are hazardous because they contain caustic acid, can emit explosive gases, and can cause electric shock. Caution must be exercised when making connections to a battery to avoid shock and contact with the acid, and to prevent any sparking that could lead to an explosion.

ALWAYS follow the general battery safety rules and instructions listed below.

General Battery

Safety Rules

• ALWAYS use eye protection when handling batteries.

• NEVER smoke or work near sparks or other sources of ignition.

• NEVER touch both battery terminals at the same time with your hand or any non-insulated tools.

• If battery acid contacts skin or clothing, flush immediately with water and neutralize with baking soda.

Connecting the battery

Disconnecting the battery

Always connect the cables in the following sequence to avoid possible shock:

1. Find the battery cables located inside the battery box.

2. Connect the red cable to the positive(+) terminal of the battery.

Storage & Exercise of Generator

Each of these procedures is discussed in detail below:

1. General safety rules for operation

Before starting the generator, review the following general safety rules for operation:

WARNING:

Failure to follow safety rules may result in serious injury or death to the operator or bystanders.

• Know proper use/how to stop. Be thoroughly familiar with proper use of the equipment and all generator controls, output receptacles, and connections. Know how to stop the generator quickly if needed (see “Operation, Step 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 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.

23

Operation (cont’d)

• Malfunction during operation. Immediately turn off the generator if any of the following conditions arise during operation: o

Excessive change in engine speed, slow or fast o

Overheating in load connecting devices o

Sparking or arcs from generator o

Loss of electrical output o

Receptacle damage o

Engine misfire o

Excessive vibration o

Flame or smoke o

Abnormal noise

• Adjusting / repairing. Always turn off generator and remove spark plug(s) or spark plug wire(s) before working on the generator to prevent accidental starting. Always discharge the capacitor before working on the generator head to prevent electrical shock. (See Maintenance & Repair section of this manual for instructions on how to do this.)

• Carbon monoxide poisoning. The running engine gives off carbon monoxide, a poisonous gas that can kill you. You CANNOT smell it, see it, or taste it. Follow all instructions for site selection and positioning the generator, and avoid inhaling the exhaust. If you start to feel sick, dizzy, or weak while using the generator, shut off the engine and get to fresh air RIGHT AWAY. See a doctor. You may have carbon monoxide poisoning.

• Other exhaust dangers. This product contains or emits chemicals known to the State of California to cause cancer, birth defects or other reproductive harm. Avoid inhalation of exhaust.

• Wet conditions. Do not operate the generator or handle any electrical equipment while standing in water, while barefoot, while hands are wet or while in the rain or snow. Electric shock may result.

• Ground fault circuit interrupter. Always use a ground fault circuit interrupter (GFCI) protected extension cord (or outlet, if generator is equipped) in damp or highly electrical conductive areas and on construction jobsites to prevent electrical shock.

• Avoid contact. Avoid contact with bare wires, terminals, connections, etc. while the unit is running.

• Electric shock accident. If an electric shock accident occurs, immediately shut down the source of electrical power. If this is not possible, attempt to free the victim from the live conductor. Avoid direct contact with victim. Use a nonconducting implement, such as a dry rope or board, to free the victim from the live conductor. Apply first aid and get immediate medical help.

• Smoking/sparks. Never smoke near the running generator, and never operate near sources of sparks or flames.

• Hot muffler. Never touch hot muffler, hot exhaust manifold, or engine cooling fins. Exhaust and engine parts can be very hot and will burn you.

• Moving parts. Keep hands, feet, and apparel away from drive belts, fans, and other moving parts. Never remove any drive belt or fan guard while the unit is operating.

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: 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. 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.

25


2. Preparing for Operation

Position generator Position generator in accordance with the instructions given in

“Installation & Initial Set-up, Step 5: Select a Suitable Site” of this

manual.

Operate outside only, on dry, level ground with adequate clearance and 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 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.

Ground generator Make sure the generator is grounded in accordance with instruction given in “Installation & Initial Set-up, Step 6: Grounding the

Generator” of this manual.

WARNING: Electric shock hazard

Always ensure generator is properly grounded to prevent electrical shock.

Perform scheduled maintenance as needed

Make sure that any regular maintenance has been performed as prescribed in this manual in the “Maintenance & Repair” section.

1. Refer to the engine owner’s manual for engine maintenance instructions.

2. Make sure battery is charged. Charge as needed according to your battery manufacturer’s instructions.

Check/add oil Check the oil level using the dipstick and add oil as needed.

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.

26

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:

27

Start LPG/NG supply

(if using)


•

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 lockopen 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.

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.

Use the leak test method described below.

28


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, 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.

29


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 starting the engine, especially for cold starts.

NOTE: If you have trouble starting the engine with LP/NG, you may need to adjust the load block: a. Loosen the lock nut, then turn the adjustment screw clockwise until resistance is felt. At this point the load block is completely shut-off.

WARNING:


To start engine using gasoline:

1) Disconnect all loads to the generator.

2) Flip the fuel selector switch to the GASOLINE position.

3) Turn the gasoline line valve to the ON position.

4) For cold engine, move choke lever to full choke position. To restart a warm engine, move choke lever to half choke or to RUN position.

5) Start the engine: a) Using electric start – i) Turn the engine key switch to the START position and hold it there until the engine starts.

NOTE: If the engine fails to start after 5 seconds, release key and

wait 10 seconds before attempting to start again.

Cranking the electric starter for more than 5 seconds continuously can overheat and damage the starter motor.

ii) Release the key when the engine starts. b) Using recoil start – i) Turn the engine key switch to the ON position. ii) Pull the starter grip lightly until you feel resistance, then pull the starter cord out briskly and rapidly. iii)

Allow starter cord to return slowly.

6) When engine starts, move choke lever to RUN position.

7) 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 4 hours under 100% load, and about 8 hours under 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 100 operating hours thereafter, as directed in the engine owner’s manual.

WARNING:


31


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.

32


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

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 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.

• 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.

• 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.
