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).
Safety Rules
• 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.
• Do not insert objects through unit’s cooling slots.

the manufacturers instructions.
2.3.1 GROUNDING THE GENERATOR
This generator has an equipment ground that connects the generator
frame components to the ground terminals on the AC output
receptacles (see NEC 250.34 (A) for explanation). This allows the
generator to be used as a portable without grounding the frame of the
generator as specified in NEC 250.34.
2.3.1.1 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.
2.3.2 CONNECTING THE GENERATOR TO A BUILDING’S
ELECTRICAL SYSTEM
When connecting directly to a building’s electrical system, it is

2.3.3 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".
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.

2.6 BEFORE STARTING THE GENERATOR
Prior to operating the generator, engine oil and gasoline will need to
be added, as follows:
2.6.1 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 32 °F (0 °C), use SAE 30
• Between 40 °F and -10 °F (4 and -32 °C), use 10W-30
• Synthetic 5W-30 for all temperature ranges
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
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 and dipstick.
3. Wipe dipstick clean.
4. 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.
5. Install oil fill cap and finger tighten securely.
6. 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.
1. 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.
2. Clean area around fuel fill cap, remove cap.
3. Slowly add unleaded regular gasoline to fuel tank. Be careful
not to overfill (Figure 8).
4. 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.
1. Unplug all electrical loads from the unit's receptacles before
starting the engine.
2. Make sure the unit is in a level position (not to exceed 15° in any
direction).
3. Turn the Fuel Shut-off Valve to the "ON" position (Figure 9).
4. Turn engine ON/OFF switch to ON position (Figure 9).
5. Move engine CHOKE lever to the START position (Figure 10).
6. To start engine, firmly grasp the recoil handle and pull slowly until
increased resistance is felt. Pull rapidly up and away.
7. 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
1. 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.
2. Let engine run at no-load for several minutes to stabilize the
internal temperatures of engine and generator.
3. Move ON/OFF switch to OFF position.
4. 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.
3.1 MAINTENANCE SCHEDULE
Follow the calendar intervals. More frequent service is required when
operating in adverse conditions noted below.
Check Oil Level At Each Use

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.
Never insert any object or tool through the air
cooling slots, even if the engine is not running.
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 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.
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.
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.
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 to drain oil
completely into a suitable container.
3. When oil has completely drained, install oil drain plug and tighten
securely.
4. Fill engine with recommended oil. (See “Before Starting the
Generator” for oil recommendations).
5. Wipe up any spilled oil.
6. Dispose of used oil at a proper collection center.

Maintenance
3.3.6 REPLACING THE SPARK PLUG
Use spark plug F6TC, NGK BPR4ES or Champion 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.
1. Remove air filter cover.
2. Wash in soapy water. Squeeze filter dry in clean cloth (DO NOT
TWIST).
3. Clean air filter cover before re-installing it.

3.5 VALVE CLEARANCE
• Intake — 0.10 ± 0.02 mm (cold), (0.004" ± 0.001" in)
• Exhaust — 0.15 ± 0.02 mm (cold) (0.006" ± 0.001" in)
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 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.

Maintenance
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:
1. Remove all gasoline from the fuel tank. Use a commercially
available, non-conductive vacuum siphon.
Drain fuel into approved container outdoors,
away from open flame. Be sure engine is cool.
Do not smoke.
2. Start and run engine until engine stops from lack of fuel.
3. Drain oil from crankcase after the engine cools down. Refill with
recommended grade.
4. Remove the spark plug and pour about 1/2 oz (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.
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.
Avoid spray from spark plug hole when
cranking engine.
5. Install and tighten spark plugs. Do not connect spark plug wire.
6. Clean the generator outer surfaces. Check that cooling air slots
and openings on generator are open and unobstructed.
7. Store the unit in a clean, dry place
