1
Safety Rules
• 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 use inside, or in partly enclosed areas such as
garages, EVEN IF doors and windows are open! ONLY use
outdoors and far from windows, doors and vents. Only use 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 per forming 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.
2
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.

2.2.1 120 VAC, 20 AMP, DUPLEX RECEPTACLE
This is a 120 Volt outlet protected against overload by a 13.5 Amp
push-to-reset circuit breaker (Figure 6). 13.5 Amps of current may
be drawn from each socket, however, total power drawn must be
kept within data plate ratings. Use only high quality, well insulated,
3-wire grounded cord sets rated for 125 Volts at 20 Amps (or
greater).
2.3 HOW TO USE THE GENERATOR
If there are any problems operating the generator, please call the
generator helpline at 1-888-436-3722.
NEVER use inside, or in partly enclosed
areas such as garages, EVEN IF doors and
windows are open! ONLY use outdoors and
far from 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.
2.3.1 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 (Figure 7).
Local electrical codes may also 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 7 - Grounding the Generator
2.3.2 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".

Operation
2.4 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.

Any attempt to crank or start the engine
before it has been properly serviced with the
recommended oil may result in an engine
failure.
7
Operation
• Place generator on a level surface.
• Clean area around oil fill and remove oil fill cap and dipstick.
• Wipe dipstick clean.
• Slowly fill engine with oil through the oil fill opening until it
reaches the full mark on the dipstick. Stop filling occasionally
to check oil level. Be careful not to over fill.
• Install oil fill cap and finger tighten securely.
• Check engine oil level before starting each time thereafter.
2.6.2 ADDING GASOLINE
Never fill fuel tank indoors. Never fill fuel tank
when engine is running or hot. Allow engine
to cool entirely before filling fuel tank. Avoid
spilling gasoline on HOT engine. 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 overflow onto a HOT
engine and cause FIRE or EXPLOSION.
• Use regular UNLEADED gasoline with the generator engine. Do
not use any gasoline with more than 10% added Ethanol, and
never use E85 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 8).
• 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.
2.7 TO START THE ENGINE
Never start or stop engine with electrical
devices plugged into the receptacles AND
devices turned on.
• Unplug all electrical loads from the unit's receptacles before
starting the engine.
• Make sure the unit is in a level position.
• Turn the Fuel Shut-off Valve to the "ON" position (Figure 9).
• Turn engine ON/OFF switch to ON position (Figure 9).
• Move engine CHOKE lever to the START position (Figure 10).
• To start engine, firmly grasp the recoil handle and pull slowly
until increased resistance is felt. Pull rapidly up and away.
• When engine starts, move choke lever to 1/2-CHOKE position
until engine runs smoothly and then fully into RUN position. If
engine falters, move choke back out to 1/2-CHOKE position
until engine runs smoothly and then to RUN position.
NOTE:
If engine fires, but does not continue to run, move choke lever to
the START position and repeat starting instructions.

IMPORTANT: Do not overload the generator. Also, do not
overload individual panel receptacles. These outlets are protected
against overload with push-to-reset-type circuit breakers. If
amperage rating of any circuit breaker is exceeded, that breaker
opens and electrical output to that receptacle is lost. Read “Don’t
Overload the Generator” carefully.
2.8 STOPPING THE ENGINE
• Shut off all loads, then unplug the electrical loads from
generator panel receptacles. Never start or stop the engine with
electrical devices plugged in and turned on.
• Let engine run at no-load for several minutes to stabilize the
internal temperatures of engine and generator.
• Move ON/OFF switch to OFF position.
• Close fuel valve.
2.9 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.
2.9.1 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.
3.1 MAINTENANCE SCHEDULE

Maintenance
3.3 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 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.
3.3.1 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.
3.3.3 ENGINE MAINTENANCE
When working on the generator, always
disconnect spark plug wire from spark plug
and keep wire away from spark plug.
3.3.4 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 (Figure 11).
Figure 11 - Oil Drain, Check & Fill
Oil Drain
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.
3.3.2 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.
Oil Check & Fill
3.3.5 CHANGING THE OIL
Change the oil after the first 20 hours of operation, then every
season. 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 while the engine
is still warm:
• 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 engine 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.

Maintenance
3.3.6 REPLACING THE SPARK PLUG
Use spark plug F6TC, NGK BPR4ES or Champioin RN14YC.
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
and torque to 15 ft/lbs. (Figure 12).
Figure 12 - Spark Plug Gap
3.3.7 SPARK ARRESTOR
1. Shut off generator and allow the engine and muffler to cool
down completely before servicing spark arrestor (located on
the back of the muffler).
2. Remove the clamp and spark arrestor screen.
3. Clean the spark arrestor screen with a small wire brush.
4. Replace the spark arrestor if it is damaged.
5. Installation of the spark arrestor screen is the reverse of the
removal.
3.4 SERVICE AIR FILTER
The engine will not run properly and may be damaged if using a
dirty air filter. Clean the air filter once a year (Figure 13). Clean or
replace more often if operating under dusty conditions.
• Remove air filter cover.
• Wash in soapy water. Squeeze filter dry in clean cloth (DO NOT
TWIST).
• Clean air filter cover before re-installing it.
NOTE:
To order a new air filter, please contact the nearest authorized
service center at 1-888-436-3722.
Figure 13 - Air Filter

3.5 VALVE CLEARANCE
• Intake — 0.10 ± 0.02mm (cold), (0.003" ± 0.001" inches)
• Exhaust — 0.15 ± 0.02mm (cold) (0.005" ± 0.001" 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.
3.6 GENERAL
The generator should be started at least once every seven 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.
3.7 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:
• Remove all gasoline from the fuel tank.
11
Maintenance
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.
• While engine is still warm, drain oil from crankcase. Refill with
recommended grade.
• Remove spark plugs and pour about 1/2 ounce (15 ml) of
engine oil into the cylinders. Cover spark plug hole with rag.
Pull the recoil starter a couple times to lubricate the piston rings
and cylinder bore.
Avoid spray from spark plug holes when
cranking engine.
• Install and tighten spark plugs. Do not connect spark plug wires.
• 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.
3.8 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.
• Cover the unit with a suitable protective cover that does not
retain moisture.
NEVER cover the generator while engine and
exhaust areas are warm.
