generator.
• Do not insert objects through unit’s cooling slots.
Introduction
1

• When working on this equipment, remain alert at all times.
Never work on the equipment when physically or mentally
fatigued.
• Lifting Warning Hazard: A falling generator can result in death,
bodily injury, and/or property damage. Stand clear of generator.
Lift is designed to carry only the weight of the generator. DO
NOT overload lifting bracket. Apply lifting strap or hook through
lift bar hole(s) only. DO NOT lift while generator is running.
• 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.
NOTE:
This generator is equipped with a spark arrestor muffler. The
spark arrestor must be maintained in effective working order
by the owner/ operator. In the State of California, a spark
arrestor is required by law (Section 4442 of the California
Public Resources Code). Other states may have similar laws.
Federal laws apply on federal lands.
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 manufacturer's 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.
NEVER 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.
Safety Rules

2.3.4 GROUND FAULT SENSING MODULE
This unit is equipped with a ground fault circuit interrupter (GFCI).
This device meets applicable federal, state and local codes. The
ground fault sensing module covers all receptacles.
In the event of a ground fault, the GFCI will trip and quickly stop the
flow of electricity to prevent serious injury.
Definition: The GFCI constantly monitors electricity flowing in a
circuit. If the current flowing through the circuit varies from what
is returning by even a small amount, the GFCI instantly switches
power off by tripping the main circuit breaker on the generator's
control panel.
A GFCI does NOT protect against circuit overloads, short circuits,
or shocks. For example, electric shock can still occur if a person
touches charged electrical wires while standing on a non-
conducting surface, such as a wood floor.
Test the GFCI outlet before each use as follows (Figure 14):
1. Start the generator.
2. Plug a test lamp into duplex receptacle, the lamp should be on.
3. Press the “Test” button on the GFCI to trip the device. The main
breaker should ‘trip’, this being indicated by the movement of
the actuator handle to the ‘OFF’ position.
4. This should stop the flow of electricity making the lamp shut
off. If the main breaker does not ‘trip’, the GFCI is not working
and the generator should not be used. Contact a local service
dealer.
5. To restore the flow of electricity, set the main breaker actuator
handle to the ‘ON’ position. The handles should remain
latched in this position. If it does not, either the GFCI or the
main breaker is failing and should be replaced. Contact a local
service dealer.
6. This GFCI is protected against overload by a 35A/240V main

2.4 AUTOMATIC IDLE CONTROL (IF EQUIPPED)
This feature is designed to greatly improve fuel economy. When
this switch is turned “On,” the engine will only run at its normal
fast governed engine speed when electrical load is connected.
When the load is removed, the engine will run at a reduced speed.
With the switch “Off,” the engine runs at the normal fast engine
speed all the time. Always have the switch OFF when starting and
stopping the engine (Figure 13).
2.5 VOLTAGE SELECTOR SWITCH (3.6 & 6.5KW
ONLY)
Allows the user to choose between 120/240 volts, or 120 volt
only. When in the 120 volt only position, the total generator output
is available through any of the 120 volt outlets. In the 120/240V
position, receptacles of 120 and 240 volts AC can be used
simultaneously. The voltage selector switch provides the user with
more usable power and improved flexibility.
NOTE:
NEVER switch the voltage selector switch with the main breaker
turned on! Doing this can cause arcing and can damage the
generator. First turn off all tools and appliances, turn off the
main circuit, and then operate the voltage selector switch.
2.6 HOW TO USE THE GENERATOR
If there are any problems operating the generator, please call the
generator helpline at 1-888-436-3722.

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 manufacturer's
instructions.
2.6.1 SYSTEM GROUND
The generator has a system ground that connects the generator
frame components to the ground terminals on the AC output
receptacles.
NOTE:
This generator system ground IS bonded to the neutral in the
generator (see applicable unit wiring diagram).
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 through a
Transfer Switch
IMPORTANT: 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 related
laws and codes.
NOTE:
This generator system ground IS bonded to the neutral in the
generator (see applicable unit wiring diagram).

12
Operation
2.6.2 GROUNDING THE GENERATOR
Local electrical codes may require proper grounding of the unit. 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 16 - Grounding the Generator
2.6.3 CONNECTING ELECTRICAL LOADS
DO NOT connect 240 Volt loads to 120 Volt receptacles. DO NOT
connect 3-phase loads to the generator. DO NOT connect 50 Hz
loads to the generator.
• Let engine stabilize and warm up for a few minutes after
starting.
• Plug in and turn on the desired 120 or 240 Volt AC, single
phase, 60 Hz electrical loads.
• Add up the rated watts (or amps) of all loads to be connected
at one time. This total should not be greater than (a) the rated
wattage/amperage capacity of the generator or (b) circuit
breaker rating of the receptacle supplying the power. See "Don't
Overload the Generator".
2.7 OVERLOAD PREVENTION
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.

2.9 BEFORE STARTING THE GENERATOR
Prior to operating the generator, engine oil and gasoline will need
to be added, as follows:
2.9.1 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
SA E 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.
3.6 - 8kW Portables
1. Place generator on a level surface (not to exceed 15° in any
direction).
2. Clean area around oil fill and remove oil fill cap.
3. Slowly fill engine with oil through the oil fill opening until it
reaches the full mark. Stop filling occasionally to check oil
level. The engine is full when the oil level reaches the bottom
threads of the mating oil fill cap.
4. Install the oil fill cap and finger tighten securely.
5. Check engine oil level before starting each time thereafter.
10kW Portables:
1. Place generator on a level surface (not to exceed 15° in any
direction).
2. Clean area around oil fill and remove oil dipstick
3. Slowly fill engine with oil through the oil dipstick tube. Stop
filling occasionally to check oil level. The engine is full when
the oil reaches the full mark on the dipstick.
4. Install the oil dipstick.
5. Check engine oil level before starting each time thereafter.
2.9.2 ADDING GASOLINE
Use care when fueling the generator. Only fill the fuel tank when the
generator has cooled entirely. Use fresh unleaded gasoline with a
minimum Research Octane Number (RON) of 87.
NOTE:
Do not use any gasoline containing more than 10% Ethanol.
NEVER fill the fuel tank with E85 or a mixture of oil and gasoline
designated for two-cycle engines.

NEVER light a cigarette or smoke when filling the fuel
tank.

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 fill fuel tank indoors. Never fill fuel tank when
engine is running or hot. Avoid spilling gasoline on a hot
engine. Allow engine to cool entirely before filling fuel
tank.

Do not overfill the fuel tank. Always allow room for fuel
expansion. If the fuel tank is overfilled, fuel can overflow
onto a hot engine and cause a fire or an explosion. Wipe
up any fuel spills immediately.
• Use regular UNLEADED gasoline with the generator engine. Do
not use premium gasoline. Do not mix oil with gasoline.
1. Clean area around fuel fill cap, remove cap.
2. Slowly add unleaded regular gasoline to fuel tank. Do not fill
above inner lip. Be careful not to overfill (Figure 17).
3. Install fuel cap and wipe up any spilled gasoline.
Operation

14
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.

2.13 LOW OIL LEVEL SHUTDOWN SYSTEM
The engine is equipped with a low oil level sensor that shuts down
the engine automatically when the oil level drops below a specified
level. If the engine shuts down by itself and the fuel tank has
enough gasoline, check engine 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.
2.14 CHARGING THE BATTERY (IF EQUIPPED)

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.

Never 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
WILL 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 20).

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:
Once a year replace the spark plug(s) and replace the air filter.
A new spark plug(s) and a 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
awaydirt. Inspect cooling air slots and openingsonthegenerator.
These openings must be kept clean and unobstructed.
3.4.3 ENGINE MAINTENANCE

When working on the generator, always disconnect
the negative cable from the battery (if equipped). Also
disconnect spark plug wire(s) from spark plug(s) and
keep wire(s) away from spark plug(s).
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 AND OIL FILTER
Change the oil and oil filter 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:
1. Clean area around oil drain plug.
2. Remove oil drain plug from engine and oil fill plug (or dipstick)
to drain oil completely into a suitable container.
3. When oil has completely drained, install oil drain plug and
tighten securely.
4. Place a suitable container beneath the oil filter and turn filter
counterclockwise to remove. Discard according to local
regulations.
5. Coat gasket of new filter with clean engine oil. Turn filter
clockwise until gasket contacts lightly with filter adapter. Then
tighten an additional 3/4 turn.
6. Fill engine with recommended oil. (See “Before Starting the
Generator” for oil recommendations).
7. Wipe up any spilled oil.
8. Replace oil fill plug (or dipstick).
9. Dispose of used oil at a proper collection center.
3.4.6 REPLACING THE SPARK PLUG(S)
See Engine Specifications for recommended spark plug(s).
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(s) off of the spark
plug(s).
2. Clean the area around the spark plug(s) and remove it from the
cylinder head(s).
3. Set the spark plug's gap to 0.70-0.80 mm (0.028-0.031 in.).
Install the correctly gapped spark plug(s) into the cylinder
head(s) (Figure 21).
