DANGER:

GROUNDING THE GENERATOR

To reduce the risk of shock or electrocution, generator must be properly

grounded. The nut and ground terminal on the frame must always be

used to connect the generator to a suitable ground source. The ground

path should be made with #8 size wire. Connect the terminal of the

ground wire between the lock washer and the nut, and tighten the nut

fully. Connect the other end of the wire securely to a suitable ground

source.

The National Electric Code contains several practical ways in which to

establish a good ground source. If a steel or iron rod is used, it should

be at least 5/8 in. diameter, and if a nonferrous rod is used, it should be

at least 1/2 in. diameter and be listed as material for grounding. Drive

the rod or pipe to a depth of 8 ft. If a rock bottom is encountered less

than 4 ft. down, bury the rod or pipe in a trench.

All electrical tools and appliances operated from this generator must

be properly grounded by use of a third wire or be “Double Insulated.”

It is recommended to:

1. Use electrical devices with 3-prong grounded plugs.

2. Use an extension cord with a 3-pole receptacle and a 3-prong plug at opposite ends to ensure continuity of the

ground protection from the generator to the appliance.

Check and adhere to all applicable federal, state, and local regulations relating to grounding specifications. Consult a

qualified electrician or service personnel if the grounding instructions are not completely understood or if in doubt as

to whether the generator is properly grounded.

IMPORTANT SAFETY INSTRUCTIONS

DANGER:

Carbon Monoxide. Using a generator indoors CAN KILL

YOU IN MINUTES.

Generator exhaust contains high levels of carbon mon-

oxide (CO), a poisonous gas you cannot see or smell. If

you can smell the generator exhaust, you are breathing

CO. But even if you cannot smell the exhaust, you could

be breathing CO.

 Never use a generator inside homes, garages, crawl-

spaces, or other partly enclosed areas. Deadly levels

of carbon monoxide can build up in these areas.

Using a fan or opening windows and doors does NOT

supply enough fresh air.

 ONLY use a generator outdoors and far away from

open windows, doors, and vents. These openings

can pull in generator exhaust.

Even when you use a generator correctly, CO may leak

into the home. ALWAYS use a battery-powered or bat-

tery-backup CO alarm in the home.

If you start to feel sick, dizzy, or weak after the generator

has been running, move to fresh air RIGHT AWAY. See a

doctor. You could have carbon monoxide poisoning.

WARNING:

Read and understand all instructions. Failure to follow

all instructions listed below may result in electrocution,

fire, and/or carbon monoxide poisoning, which will cause

death or serious injury.

WARNING:

National Electric Code requires generator to be grounded

to an approved earth ground. Before using the ground

terminal, consult a qualified electrician, electrical inspec-

tor, or local agency having jurisdiction for local codes

or ordinances that apply to the intended use of the

generator.

SAVE THESE INSTRUCTIONS

This manual contains important instructions that should be

followed during installation and maintenance of the genera-

tor and batteries.



Do not connect to a building’s electrical system unless

the generator and transfer switch have been properly

installed and the electrical output has been verified by

a qualified electrician. The connection must isolate the

generator power from utility power and must comply with

all applicable laws and electrical codes.

 Do not allow children or untrained individuals to use this

unit.

 Never start or run the engine inside a closed or partially

enclosed area. Breathing exhaust fumes will kill you.

 Keep all bystanders, children, and pets at least 10 feet

away.

 Wear sturdy and dry shoes or boots. Do not operate while

barefoot.

 Do not operate generator when you are tired or under the

influence of drugs, alcohol, or medication.

 Keep all parts of your body away from any moving parts

and all hot surfaces of the unit.

 Do not touch bare wire or receptacles.

 Do not use generator with electrical cords which are

worn, frayed, bare, or otherwise damaged.

 Before storing, allow the engine to cool and drain fuel

from the unit.

 Do not operate or store the generator in rain, snow, or

wet weather.

 Store the generator in a well-ventilated area with the fuel

tank empty. Fuel should not be stored near the generator.

 Empty fuel tank, close fuel valve, and restrain the unit

from moving before transporting in a vehicle.

 Allow engine to cool for five minutes before refueling.

 To reduce the risk of fire and burn injury, handle fuel with

care. It is highly flammable.

 Do not smoke while handling fuel.

 Store fuel in a container approved for gasoline.

 Position the unit on level ground, stop engine, and allow

to cool before refueling.

 Loosen fuel cap slowly to release pressure and to keep

fuel from escaping around the cap.

 Tighten the fuel cap securely after refueling.

 Wipe spilled fuel from the unit.

 Never attempt to burn off spilled fuel under any circum-

stances.

 Generators vibrate in normal use. During and after the

use of the generator, inspect the generator as well as

extension cords and power supply cords connected to

it for damage resulting from vibration. Have damaged

items repaired or replaced as necessary. Do not use plugs

or cords that show signs of damage such as broken or

cracked insulation or damaged blades.

 For power outages, permanently installed stationary gen-

erators are better suited for providing back-up power to

the home. Even a properly connected portable generator

can become overloaded. This may result in overheating

or stressing the generator components, possibly leading

to generator failure.

SPECIFIC SAFETY RULES

WARNING:

When this generator is used to supply a building

wiring system: generator must be installed by a quali-

fied electrician and connected to a transfer switch as

a separately derived system in accordance with NFPA

70, National Electrical Code. The generator shall be

connected through a transfer switch that switches all

conductors other than the equipment grounding con-

ductor. The frame of the generator shall be connected to

an approved grounding electrode. Failure to isolate the

generator from power utility can result in death or injury

to electric utility workers.



Do not use this generator to provide power for emergency

medical equipment or life support devices.



This generator has a neutral bonded condition. This means

the system ground is connected electrically to the AC

neutral wire.



Exhaust contains poisonous carbon monoxide, a color-

less, odorless gas. Breathing exhaust can cause loss

of consciousness and can lead to death. If running in a

confined or partially-enclosed area, the air may contain

a dangerous amount of carbon monoxide. To keep ex-

haust fumes from building up, always provide adequate

ventilation.



Always use a battery-powered carbon monoxide detec-

tor when running the generator. If you begin to feel sick,

dizzy, or weak while using the generator, shut it off and

get to fresh air immediately. See a doctor. You may have

carbon monoxide poisoning.

GENERATOR CAPACITY

Make sure the generator can supply enough continuous (run-

ning) and surge (starting) watts for the items you will power

at the same time. Follow these simple steps.

1. Selecttheitemsyouwillpoweratthesametime.

2. Totalthecontinuous(running)wattsoftheseitems.This

is the amount of power the generator must produce to

keep the items running. See the wattage reference chart

at right.

3. Estimatehowmanysurge(starting)wattsyouwillneed.

Surge wattage is the short burst of power needed to

start electric motor-driven tools or appliances such as a

circular saw or refrigerator. Because not all motors start

at the same time, total surge watts can be estimated by

adding only the item(s) with the highest additional surge

watts to the total rated watts from step 2.

To prolong the life of the generator and attached devices,

it is important to take care when adding electrical loads to

the generator. There should be nothing connected to the

generator outlets before starting its engine. The correct and

safe way to manage generator power is to sequentially add

loads as follows:

1. With nothing connected to the generator, start the engine

as described later in this manual.

2. Plug in and turn on the first load, preferably the largest

load you have.

3. Permit the generator output to stabilize (engine runs

smoothly and attached device operates properly).

4. Plug in and turn on the next load.

5. Again, permit the generator to stabilize.

6. Repeat steps 4 and 5 for each additional load.

Never add more loads than the generator capacity. Take

special care to consider surge loads in generator capacity

as previously described.

CAUTION:

Do not overload the generator’s capacity. Exceeding the

generator’s wattage/amperage capacity can damage the

generator and/or electrical devices connected to it.

DANGER:

Carbon Monoxide. Using a generator indoors CAN KILL

YOU IN MINUTES.

Generator exhaust contains high levels of carbon mon-

oxide (CO), a poisonous gas you cannot see or smell. If

you can smell the generator exhaust, you are breathing

CO. But even if you cannot smell the exhaust, you could

be breathing CO.

 Never use a generator inside homes, garages, crawl-

spaces, or other partly enclosed areas. Deadly levels

of carbon monoxide can build up in these areas. Us-

ing a fan or opening windows and doors does NOT

supply enough fresh air.

 ONLY use a generator outdoors and far away from

open windows, doors, and vents. These openings

can pull in generator exhaust.

Even when you use a generator correctly, CO may

leak into the home. ALWAYS use a battery-powered or

battery-backup CO alarm in the home.

If you start to feel sick, dizzy, or weak after the generator

has been running, move to fresh air RIGHT AWAY. See a

doctor. You could have carbon monoxide poisoning.

DANGER:

Failure to properly ground generator can result in elec-

trocution, especially if the generator is equipped with a

wheel kit. National Electric Code requires generator to be

properly grounded to an approved earth ground. Call an

electrician for local grounding requirements.

WARNING:

Do not allow familiarity with this product to make you

careless. Remember that a careless fraction of a second

is sufficient to inflict serious injury.

WARNING:

Do not use any attachments or accessories not

recommended by the manufacturer of this product. The

use of attachments or accessories not recommended

can result in serious personal injury.

Before each use, inspect the entire product for damaged,

missing, or loose parts such as screws, nuts, bolts, caps, etc.

Tighten securely all fasteners and caps and do not operate

this product until all missing or damaged parts are replaced.

Please contact an authorized service center for assistance.

APPLICATIONS

This generator is designed to supply electrical power for

operating compatible electrical lighting, appliances, tools,

and motor loads.

BEFORE OPERATING THE UNIT

 Only use OUTSIDE and far away from windows, doors,

and vents.

 NEVER use inside a home or garage, EVEN IF doors and

windows are open.

 Always position the generator on a flat firm surface.

SPECIAL REQUIREMENTS:

There may be General or State Occupational Safety and

Health Administration (OSHA) regulations, local codes or

ordinances that apply to the intended use of the generator.

Please consult a qualified electrician, electrical inspector, or

the local agency having jurisdiction:

 In some areas, generators are required to be registered

with local utility companies.

 If the generator is used at a construction site, there may

be additional regulations which must be observed.

CAUTION:

Attempting to start the engine before it has been properly

filled with lubricant will result in equipment failure.

CHECKING/ADDING LUBRICANT

See Figure 7.

Engine lubricant has a major influence on engine perfor-

mance and service life. For general, all-temperature use,

SAE 10W-30 is recommended. Always use a 4-stroke motor

lubricant that meets or exceeds the requirements for API

service classification SJ.

NOTE: Non-detergent or 2-stroke engine lubricants will

damage the engine and should not be used.

 Unscrew the oil cap/dipstick and remove.

OPERATION

Page 14 — English

OPERATION

 Wipe dipstick clean and re-seat in hole; do not re-thread.

 Remove dipstick again and check lubricant level. Lubri-

cant level should fall between the hatched areas on the

dipstick.

 If level is low, add engine lubricant until the fluid level rises

to the upper portion of the dipstick.

 Replace and secure the oil cap/dipstick.

CHECKING/ADDING FUEL

See Figure 8.

 Remove the fuel cap.

 Fill the fuel tank to 1 in. below the top of the fuel neck.

 Replace and secure the fuel cap.

NOTE: Always use unleaded gasoline with a pump octane

rating of 86 or higher. Never use old, stale, or contaminated

gasoline, and do not use an oil/gas mixture. Do not allow

dirt or water into the fuel tank.

USING FUEL STABILIZER

Fuel gets old, oxidizes, and breaks down over time. Adding

a fuel stabilizer (not included) extends the usable life of fuel

and helps prevent deposits from forming that can clog the

fuel system. Follow fuel stabilizer manufacturer’s directions

for correct ratio of stabilizer to fuel.

 Add stabilizer to fuel tank, then fill with gasoline following

previous instructions.

NOTE: Fuel stabilizer and gasoline can be mixed prior

to filling the tank by using a gas can or other approved

fuel container and shaking gently to combine.

 Replace and secure the fuel tank cap.

 Start and run the engine for at least 5 minutes to allow

stabilizer to treat the entire fuel system.

OXYGENATED FUELS

DO NOT USE E85 FUEL. IT WILL VOID YOUR

WARRANTY.

NOTE: Fuel system damage or performance problems re-

sulting from the use of an oxygenated fuel containing more

than the percentages of oxygenates stated previously are

not covered under warranty.

Ethanol. Gasoline containing up to 10% ethanol by volume

(commonly referred to as E10) is acceptable. E85 is not.

CAUTION:

On a level surface with the engine off, check the lubricant

level before each use of the generator.

STARTING THE ENGINE

See Figures 9 - 11.

NOTE: If location of generator is not level, the unit may not

start or may shut down during operation.
