Introduction

2
• Never use the generator or any of its parts as a step. Stepping
on the unit can stress and break parts, and may result in
dangerous operating conditions from leaking exhaust gases,
fuel leakage, oil leakage, etc.
• On electric start models, disconnect the POSITIVE (+) battery
cable from the engine starter OR the NEGATIVE (-) battery
cable from the battery terminal, whichever is easier, before
transporting the generator.
EXHAUST & LOCATION HAZARDS
• Never operate in an enclosed area or indoors! NEVER use
in the home, in a vehicle, or in partly enclosed areas such
as garages, even if doors and windows are open! ONLY use
outdoors and far from open windows, doors, vents, and in an
area that will not accumulate deadly exhaust.
• The engine exhaust fumes contain carbon monoxide, which
you cannot see or smell. This poisonous gas, if breathed in
sufficient concentrations, can cause unconsciousness or even
death.
• Adequate, unobstructed flow of cooling and ventilating air
is critical to correct generator operation. Do not alter the
installation or permit even partial blockage of ventilation
provisions, as this can seriously affect safe operation of the
generator. The generator MUST be operated outdoors.
• This exhaust system must be properly maintained. Do nothing
that might render the exhaust system unsafe or in noncompliance
with any local codes and/or standards.
• Always use a battery operated carbon monoxide alarm indoors,
installed according to the manufacturers instructions.
• If you start to feel sick, dizzy, or weak after the generator has
been running, move to fresh air IMMEDIATELY. See a doctor, as
you could have carbon monoxide poisoning.
ELECTRICAL HAZARDS
• The generator produces dangerously high voltage when in
operation. Avoid contact with bare wires, terminals, connections,
etc., while the unit is running, even on equipment connected
to the generator. Ensure all appropriate covers, guards and
barriers are in place before operating the generator.
• Never handle any kind of electrical cord or device while
standing in water, while barefoot or while hands or feet are wet.
DANGEROUS ELECTRICAL SHOCK MAY RESULT.
• The National Electric Code (NEC) requires the frame and external
electrically conductive parts of the generator be properly
connected to an approved earth ground. Local electrical codes
may also require proper grounding of the generator. Consult
with a local electrician for grounding requirements in the area.
• Use a ground fault circuit interrupter in any damp or highly
conductive area (such as metal decking or steel work).
• Do not use worn, bare, frayed or otherwise damaged electrical
cord sets with the generator.
• Before performing any maintenance on the generator, disconnect
the engine starting battery (if equipped) to prevent accidental
start up. Disconnect the cable from the battery post indicated
by a NEGATIVE, NEG or (–) first. Reconnect that cable last.
• In case of accident caused by electric shock, 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 THE VICTIM. Use a non-conducting
implement, such as a rope or board, to free the victim from the
live conductor. If the victim is unconscious, apply first aid and
get immediate medical help.
FIRE HAZARDS
• Gasoline is highly FLAMMABLE and its vapors are EXPLOSIVE.
Do not permit smoking, open flames, sparks or heat in the
vicinity while handling gasoline.
• Never add fuel while unit is running or hot. Allow engine to cool
completely before adding fuel.
• Never fill fuel tank indoors. Comply with all laws regulating
storage and handling of gasoline.
• Do not overfill the fuel tank. Always allow room for fuel
expansion. If tank is over-filled, fuel can overflow onto a hot
engine and cause FIRE or an EXPLOSION. Never store generator
with fuel in tank where gasoline vapors might reach an open
flame, spark or pilot light (as on a furnace, water heater or
clothes dryer). FIRE or EXPLOSION may result. Allow unit to
cool entirely before storage.
• Wipe up any fuel or oil spills immediately. Ensure that no
combustible materials are left on or near the generator. Keep the
area surrounding the generator clean and free from debris and
keep a clearance of five (5) feet on all side to allow for proper
ventilation of the generator.
Safety Rules

• Do not insert objects through unit’s cooling slots.
• Do not operate the generator if connected electrical devices
overheat, if electrical output is lost, if engine or generator sparks
or if flames or smoke are observed while unit is running.
• Keep a fire extinguisher near the generator at all times.

2.4.1 SYSTEM GROUND
The generator has a system ground that connects the generator
frame components to the ground terminals on the AC output
receptacles. The system ground is bonded to the AC neutral wire
in the generator control panel via a jumper wire.
Special Requirements
There may be Federal 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.
Connecting to a Building’s Electrical System
Connections for standby power to a building’s electrical system
must be made by a qualified electrician. The connection must
isolate the generator power from utility power or other alternative
power sources and must comply with all applicable laws and
electrical codes.
2.4.2 GROUNDING THE GENERATOR
The National Electrical Code requires that the
frame and external electrically conductive parts
of this generator be properly connected to an
approved earth ground.
Local electrical codes may also require proper grounding of the
unit (Figure 10). For that purpose, connecting a No. 10 AWG
(American Wire Gauge) stranded copper wire to the grounding lug
and to an earth-driven copper or brass grounding rod (electrode)
provides adequate protection against electrical shock. However,
local codes may vary widely. Consult with a local electrician for
grounding requirements in the area.
Proper grounding of the generator will help prevent electrical
shock in the event of a ground fault condition in the generator or in
connected electrical devices. Proper grounding also helps dissipate
static electricity, which often builds up in ungrounded devices.
Figure 10 - Grounding the Generator
2.5 DON’T OVERLOAD THE GENERATOR
Overloading a generator in excess of its rated wattage capacity
can result in damage to the generator and to connected electrical
devices. Observe the following to prevent overloading the unit:
• Add up the total wattage of all electrical devices to be connected
at one time. This total should NOT be greater than the
generator's wattage capacity.
• The rated wattage of lights can be taken from light bulbs. The
rated wattage of tools, appliances and motors can usually be
found on a data label or decal affixed to the device.
• If the appliance, tool or motor does not give wattage, multiply
volts times ampere rating to determine watts (volts x amps =
watts).
• Some electric motors, such as induction types, require about
three times more watts of power for starting than for running.
This surge of power lasts only a few seconds when starting
such motors. Make sure to allow for high starting wattage when
selecting electrical devices to connect to the generator:
1. Figure the watts needed to start the largest motor.
2. Add to that figure the running watts of all other connected
loads.
The Wattage Reference Guide is provided to assist in determining
how many items the generator can operate at one time.
NOTE:
All figures are approximate. See data label on appliance for
wattage requirements.

2.7 BEFORE STARTING THE GENERATOR
Prior to operating the generator, engine oil and gasoline will need
to be added, as follows:
2.7.1 ADDING ENGINE OIL
All oil should meet minimum American Petroleum Institute (API)
Service Class SJ, SL or better. Use no special additives. Select
the oil's viscosity grade according to the expected operating
temperature (also see chart).
• Above 40° F, use SAE 30
• Below 40° F and down to 10° F, use 10W-30
• Below 10° F, use synthetic 5W-30
10W-30
10W-30
SAE 30
SAE 3 0
Synthetic 5W-30
Synthetic 5W-30

Any attempt to crank or start the engine
before it has been properly serviced with the
recommended oil may result in an engine
failure.
• Place generator on a level surface (not to exceed 15° in any
direction).
• Clean area around oil fill and remove oil fill cap.
• Slowly fill engine with oil until the dipstick reads full. Stop filling
occasionally to check oil level.
• Install dipstick and finger tighten securely.
• Check engine oil level before starting each time thereafter.
2.7.2 ADDING GASOLINE

NEVER fill fuel tank indoors. Avoid spilling
gasoline on hot engine. Allow engine to cool
entirely before adding fuel. NEVER fill fuel tank
when engine is running or hot. DO NOT light
a cigarette or smoke when filling the fuel tank.
Gasoline is highly flammable and its vapors are
EXPLOSIVE.

Do not overfill the fuel tank. Always leave room
for fuel expansion. If the fuel tank is overfilled,
fuel can over flow onto a hot engine and cause
fire or an explosion. Wipe up any spilled fuel
immediately.
Operation

10
• Use regular UNLEADED gasoline with the generator engine. Do
not use premium gasoline. Do not mix oil with gasoline.
• Clean area around fuel fill cap, remove cap.
• Slowly add unleaded regular gasoline to fuel tank. Fill to bottom
of screen filter. Be careful not to overfill (Figure 11).
• Install fuel cap and wipe up any spilled gasoline.
IMPORTANT: It is important to prevent gum deposits from forming
in fuel system parts such as the carburetor, fuel hose or tank
during storage. Alcohol-blended fuels (called gasohol, ethanol
or methanol) can attract moisture, which leads to separation and
formation of acids during storage. Acidic gas can damage the fuel
system of an engine while in storage. To avoid engine problems,
the fuel system should be emptied before storage of 30 days or
longer. See the "Storage" section. Never use engine or carburetor
cleaner products in the fuel tank as permanent damage may occur.

enough gasoline, check engine oil level.
2.11.1 SENSING LOW OIL LEVEL
If the system senses a low oil level during operation, the engine
shuts down. The engine will not run until the oil has been refilled
to the proper level.
2.12 CHARGING THE BATTERY (ELECTRIC START
UNITS ONLY)

Storage batteries give off explosive hydrogen
gas while recharging. An explosive mixture will
remain around the battery for a long time after
it has been charged. The slightest spark can
ignite the hydrogen and cause an explosion.
Such an explosion can shatter the battery and
cause blindness or other serious injury.

Do not permit smoking, open flame, sparks
or any other source of heat around a battery.
Wear protective goggles, rubber apron and
rubber gloves when working around a battery.
Battery electrolyte fluid is an extremely
corrosive sulfuric acid solution that can cause
severe burns. If spill occurs flush area with
clear water immediately.
NOTE:
The battery shipped with the generator has been fully charged.
A battery may lose some of its charge when not in use for
prolonged periods of time. If the battery is unable to crank the
engine, plug in the 12V charger included in the accessory box
(see section "Charging the Battery"). RUNNING THE GENERATOR
DOES NOT CHARGE THE BATTERY.
Use battery charger plug to keep the battery charged and ready for
use. Battery charging should be done in a dry location.
1. Plug charger into “Battery Charger Input” jack, located on the
control panel. Plug wall receptacle end of the battery charger
into a 120 Volt AC wall outlet (Figure 15).

* Elevation above sea level
** At elevations above 8000 ft, the engine may experience decreased
performance
3.4 GENERAL RECOMMENDATIONS
The warranty of the generator does not cover items that have been
subjected to operator abuse or negligence. To receive full value
from the warranty, the operator must maintain the generator as
instructed in this manual.
Some adjustments will need to be made periodically to properly
maintain the generator.
All adjustments in the Maintenance section of this manual should
be made at least once each season. Follow the requirements in the
"Maintenance Schedule".
NOTE:
Clean the air filter every 20 hours. Once a year replace the
spark plug and replace the air filter. A new spark plug and clean
air filter assure proper fuel-air mixture and help the engine run
better and last longer.
3.4.1 GENERATOR MAINTENANCE
Generator maintenance consists of keeping the unit clean and dry.
Operate and store the unit in a clean dry environment where it will
not be exposed to excessive dust, dirt, moisture or any corrosive
vapors. Cooling air slots in the generator must not become clogged
with snow, leaves, or any other foreign material.
Check the cleanliness of the generator frequently and clean when
dust, dirt, oil, moisture or other foreign substances are visible on
its exterior surface.

Never insert any object or tool through the air
cooling slots, even if the engine is not running.
NOTE:
DO NOT use a garden hose to clean generator. Water can enter
the engine fuel system and cause problems. In addition, if water
enters the generator through cooling air slots, some water will
be retained in voids and crevices of the rotor and stator winding
insulation. Water and dirt buildup on the generator internal
windings will eventually decrease the insulation resistance of
these windings.
3.4.2 TO CLEAN THE GENERATOR
• Use a damp cloth to wipe exterior surfaces clean.
• A soft, bristle brush may be used to loosen caked on dirt, oil,
etc.
• A vacuum cleaner may be used to pick up loose dirt and debris.
• Low pressure air (not to exceed 25 psi) may be used to
blow away dirt. Inspect cooling air slots and openings on the
generator. These openings must be kept clean and unobstructed.
3.4.3 ENGINE MAINTENANCE

When working on the generator, always
disconnect negative cable from battery. Also
disconnect spark plug wire from spark plug and
keep wire away from spark plug.
3.4.4 CHECKING OIL LEVEL
See the “Before Starting the Generator” section for information on
checking the oil level. The oil level should be checked before each
use, or at least every eight hours of operation. Keep the oil level
maintained.
3.4.5 CHANGING THE OIL
Change the oil after the first 30 hours of operation. Change the
oil every 100 hours or every season thereafter. If running this
unit under dirty or dusty conditions, or in extremely hot weather,
change the oil more often.

Hot oil may cause burns. Allow engine to
cool before draining oil. Avoid prolonged
or repeated skin exposure with used oil.
Thoroughly wash exposed areas with soap.
Use the following instructions to change the oil after the engine
cools down:
• Clean area around oil drain plug.
• Remove oil drain plug from engine and oil fill plug to drain oil
completely into a suitable container.
• When oil has completely drained, install oil drain plug and
tighten securely.
• Fill oil sump with recommended oil. (See “Before Starting the
Generator” for oil recommendations).
• Wipe up any spilled oil.
• Dispose of used oil at a proper collection center.

14
3.4.6 REPLACING THE SPARK PLUG
See Engine Specifications for recommended spark plug. Replace
the plug once each year. This will help the engine start easier and
run better.
1. Stop the engine and pull the spark plug wire off of the spark
plug.
2. Clean the area around the spark plug and remove it from the
cylinder head.
3. Set the spark plug's gap to 0.70-0.80 mm (0.028-0.031 in.).
Install the correctly gapped spark plug into the cylinder head
(Figure 16).
Figure 16 - Spark Plug Gap
3.4.7 BATTERY REPLACEMENT (IF APPLICABLE)
NOTE:
The battery shipped with the generator has been fully charged.
A battery may lose some of its charge when not in use for
prolonged periods of time. If the battery is unable to crank
the engine, plug in the 12V charger included in the accessory
box (see the Charging a Battery section). RUNNING THE
GENERATOR DOES NOT CHARGE THE BATTERY. The part
number for this battery is 0G9449.
Figure 17 - Battery Connections

The NEGATIVE battery terminal should:
1. Always be DISCONNECTED FIRST.
2. Always be CONNECTED LAST.
3.5 SERVICE AIR CLEANER
The engine will not run properly and may be damaged if using a
dirty air cleaner. Clean the air filter every 20 hours and replace the
air cleaner paper filter once a year. Clean or replace more often if
operating under dusty conditions (Figure 18).
To clean or replace paper air filter:
• Remove air cleaner cover and remove paper filter.
• Clean paper filter by tapping it gently on a solid surface. If the
filter is too dirty, replace it with a new one. Dispose of the old
filter properly. You will need part number 0G84420151 for a
new air filter.
• Clean air cleaner cover, then insert new paper filter into the base
of the air cleaner. Re-install air cleaner cover.
Figure 18 - Air Filter
3.6 VALVE CLEARANCE
• Intake — 0.15 ± 0.02mm (cold), (0.006" ± 0.0008" inches)
• Exhaust — 0.20 ± 0.02mm (cold) (0.008" ± 0.0008" inches)
After the first 50 hours of operation, check the valve clearance
in the engine and adjust if necessary.
Important: If feeling uncomfortable about doing this procedure or
the proper tools are not available, please take the generator to the
nearest service center to have the valve clearance adjusted. This is
a very important step to ensure longest life for the engine.
Maintenance

15
3.7 GENERAL
The generator should be started at least once every 30 days and
be allowed to run at least 30 minutes. If this cannot be done and
the unit must be stored for more than 30 days, use the following
information as a guide to prepare it for storage.

NEVER store engine with fuel in tank indoors
or in enclosed, poorly ventilated areas where
fumes may reach an open flame, spark or pilot
light as on a furnace, water heater, clothes dryer
or other gas appliance.

Allow unit to cool entirely before storage.
3.8 LONG TERM STORAGE
It is important to prevent gum deposits from forming in essential
fuel system parts such as the carburetor, fuel hose or tank during
storage. Also, experience indicates that alcohol-blended fuels
(called gasohol, ethanol or methanol) can attract moisture, which
leads to separation and formation of acids during storage. Acidic
gas can damage the fuel system of an engine while in storage.
To avoid engine problems, the fuel system should be emptied
before storage of 30 days or longer, as follows:
• Add a quality gasoline stabilizer to the fuel per the manufacturers
specifications, and run the unit for 10-15 minutes.
• After engine cools down, remove all gasoline from the fuel tank.

Drain fuel into approved container outdoors,
away from open flame. Be sure engine is cool.
Do not smoke.
• Start and run engine until engine stops from lack of fuel.
• After engine cools down, drain oil from engine. Refill with
recommended grade.
• Remove spark plug and pour about 1/2 ounce (15 ml) of engine
oil into the cylinder. Cover spark plug hole with rag. Pull the
recoil starter a couple times to lubricate the piston rings and
cylinder bore. A fogging agent can also be used in the place
of oil.

Avoid spray from spark plug hole when
cranking engine.
• Install and tighten spark plug. Do not connect spark plug wire.
• Clean the generator outer surfaces. Check that cooling air slots
and openings on generator are open and unobstructed.
• Store the unit in a clean, dry place.
3.9 OTHER STORAGE TIPS
• Do not store gasoline from one season to another.
• Replace the gasoline can if it starts to rust. Rust and/or dirt in
the gasoline will cause problems with the carburetor and fuel
system.
• If possible, store the unit indoors and cover it to give protection
from dust and dirt. BE SURE TO EMPTY THE FUEL TANK.
• If it is not practical to empty the fuel tank and the unit is to
be stored for some time, use a commercially available fuel
stabilizer added to the gasoline to increase the life of the
gasoline. Run the unit for 10-15 minutes, turn off the fuel valve
and allow to run until engine stops from lack of fuel.
• Cover the unit with a suitable protective cover that does not
retain moisture.

NEVER cover the generator while engine and
exhaust areas are warm.
