SECTION 4 - PREPARATION BEFORE
OPERATION
4.1 - ADDING ENGINE OIL
All oil should meet minimum American Petroleum In-
stitute (API) Service Class SJ, SL or better. Use no special
additives. Select the oil’s Viscosity grade according to the
expected operating temperature.
• Above 40°F, use SAE 30
• Below 40°F and down to 10°F, use 10W-30
• Below 1°F, use synthetic 5W-30
NOTICE - Improper treatment of generator could damage
it and shorten its life. DO NOT attempt to crank or start
the engine before it has been properly serviced with the
recommended oil. This could result in an engine failure.
• Place generator on a at, level surface.
• Clean area around oil ll and remove oil ll cap and
dipstick. Wipe dipstick clean.
• Slowly ll engine with oil through the oil ll opening
until it reaches the full mark on the dipstick.
• Stop lling occasionally to check oil level. Be careful
do not over ll. Do not ll to the top of the tank.
• Install oil ll cap and nger tighten securely.
• Check engine oil level before starting each time
thereafter.
4.2 - ADDING FUEL
DANGER - Never ll tank indoors. Never ll fuel tank
when engine is running or hot. Turn generator engine
OFF and allow engine to cool entirely before lling
fuel tank. Avoid spilling gasoline on HOT engine. Keep
fuel away from sparks, open ames, pilot lights, heat,
and other ignition sources. DO NOT light a cigarette or
smoke when lling the fuel tank. Fuel is highly FLAM-
MABLE and its vapors are EXPLOSIVE.
• Use regular UNLEADED gasoline with the genera-
tor engine. Do not use any fuel with more than
10% added ethanol, and never use E85 fuel.
• Do not mix oil with gasoline.
• Install fuel cap and wipe up any spilled gasoline.
CAUTION - Do not overll the fuel tank. Allow space for
fuel expansion. IF the fuel tank is overlled, fuel can over-
ow onto a HOT engine and cause FIRE or EXPLOSION. If
fuel spills, wait until it evaporates before starting engine.
Check fuel lines, tank, cap and ttings frequently for cracks
or leaks. Replace if necessary.
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 stor-
age. Acidic gas can damage the fuel system and should be
emptied before storage of 30 days or longer. See the “Stor-
age”section. Never use engine or carburetor cleaner prod-
ucts in the fuel tank as permanent damage may occur.

4.3 - GROUNDING THE GENERATOR
The national Electrical Code requires that the frame and
external electrically conductive part of this generator be
properly connected to an approved earth ground.
Local electrical codes may also require proper ground-
ing 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
requirement in the area.
Proper grounding of the generator will help prevent
electrical shock in the event of 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.
INPORTANT: See page 16 for where to nd OSHA informa-
tion on Ground Fault Circuit Interrupters.

WARNING - Starter cord kickback (rapid retraction) will
pull hand and arm toward engine faster than you can let
go which could cause broken bones, fractures, bruises, or
sprains resulting in serious injury.
When starting engine, pull cord slowly until resistance is
felt and then pull rapidly to avoid kickback.
Never start or stop engine with electrical devices plugged
in and turned on.
NOTICE - If engine starts after 3 pulls but fails to run, or if
unit shuts down during operation, make sure unit is on a
level surface and check for proper oil level in crankcase.
This unit is be equipped with a low oil protection device.
Oil must be at proper level for engine to start.
WARNING - Exhaust heat/ gases could ignite combustible,
structures or damage fuel tank causing a re, resulting in
death, serious injury and/or property damage. Contact
with muer area could cause burn resulting in serious
injury.
DO NOT touch hot muer and AVOID hot exhaust gases.
Allow equipment to cool before touching. Keep at least 5
feet (152 cm) of clearance on all sides of generator includ-
ing overhead. Contact the original equipment manufac-
turer, retailer, or dealer to obtain a spark arrester designed
for the exhaust system
installed on this engine. Replacement parts must be the
same and installed in the same position as the original
parts.
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.
5.2 - CONNECTING ELECTRICAL LOADS
• Let engine stablize and warm up for a few minutes
after starting.
• Plug in and turn on the desired 120 and/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 capac-
ity of the generator or, (b) circuit breaker rating of the
receptacle supplying the power.
NOTICE - DO NOT connect 240 Volt loads to the 120 Volt
duplex receptacles.
DO NOT connect 3 phase loads to the generator.
DO NOT connect 50 Hz loads to the generator.
NOTICE - Start generator and let engine stabilize before
connecting electrical loads. Connect electrical loads such
as tools then turn them ON for operation.
Turn electrical loads OFF and disconnect from generator
before stopping generator.
NOTICE - Exceeding generators wattage/ amperage ca-
pacity could damage generator and/or electrical devices
connected to it. DO NOT exceed the generator’s wattage/
amperage capacity.
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 axed to the
device.
If the appliance, tool or motor does not give wattage,
multiply volts times ampere rating to determine watts
(volts × 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 al-
low for high starting wattage when selecting electrical
devices to connect to the generator:
Figure the watts needed to start the largest motor.
Add to that gure the running watts of all other con-
nected loads.
The wattage reference guide is provided to assist in deter-
mining how many items the generator can operate at one

time.
5.3 - STOPPING THE ENGINE
Shut o all loads then unplug the electrical loads from
generator panel receptacles. Never start or stop the en-
gine 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. See wattage
table on page 16
5.4 - 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 specied level. If the engine shuts down by
itself and the fuel tank has enough gasoline, check engine
oil level.
5.5 - HIGH ALTITUDE
At altitudes over 5,000 feet (1524 meters), a minimum 85
octane / 85 (89 RON) gasoline is acceptable. To remain
emissions compliant, high altitude adjustment is required.
Operation without this adjustment will cause decreased
performance, increased fuel consumption, and increased
emissions. See an authorized dealer for high altitude ad-
justment information. Operation of the engine at altitudes
below 2,500 feet (762 meters) with the high altitude kit is
not recommended.

6.2.1 - GENERATOR MAINTENANCE

Page | 12
OPERATING INSTRUCTIONS
BNG SERIES GASOLINE GENERATORS
Customer Service: [phone]
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 exces-
sive dust, dirt, moisture or any corrosive vapors. Cool-
ing 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.
CAUTION - 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 genera-
tor. Water can enter the engine fuel system and cause
problem. In addition, if water enters the generator
though 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 insula-
tion resistance of these windings.
6.2.2 - 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.
6.2.3 ENGINE MAINTENANCE
DANGER - When working on the generator, always
disconnect spark plug wire from spark plug and
keep wire away from spark plug.
6.2.4 CHANGE OIL
Change the oil after the rst eight hours of operation,
then every 20 hours thereafter. If running this unit
under dirty or dusty conditions, or in extremely hot
weather, change the oil more often.
CAUTION 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 ll 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 “ADDING
ENGINE OIL” for oil recommendations).
• Wipe up any spilled oil.
• Dispose of used oil at a proper collection center.
6.2.5 REPLACE THE SPARK PLUG
Use spark plug F6RTC. Replace the plug once each year.
This will help the engine start easier and run better.
• Stop the engine and pull the spark plug wire o
of the spark plug.
• Clean the area around the spark plug and
remove it from the cylinder head.
• 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.

tor (located on the back of the muer).
• Remove the clamp and spark arrestor screen.
• Clean the spark arrestor screen with a small
• wire brush.
• Replace the spark arrestor if it is damaged.
• Installation of the spark arrestor screen is the reverse
of the removal.
6.3 SERVICE AIR FILTER
The engine will not run properly and may be damaged
if using a dirty air lter. Replace the air lter once a year.
Clean or replace more often if operating under dusty
conditions.
• Remove air lter cover.
• Wash in soapy water. Squeeze lter dry ith clean cloth
(DO NOT TWIST).
• Clean air lter cover before re-installing it.
6.4 - VALVE CLEARANCE
After the rst 50 hours of operation, check the valve clear-
ance in the engine and adjust if necessary.
Important: If you are not comfortable with this proce-
dure 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.
6.5 - GENERAL
The generator should be started at least once every seven
days and be allowed to run at least 30 minutes. If this can-
not 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.
DANGER - NEVER store engine with fuel in tank indoors
or in enclosed, poorly ventilated areas where fumes may
reach an open ame, spark or pilot light as on a furnace,
water heater, clothes dryer or other gas appliance.
CAUTION - Avoid spray from spark plug holes when crank-
ing engine.

DANGER - Drain fuel into approved container outdoors,
away from open ame. Be sure engine is cool. Do not
smoke.
DANGER - NEVER cover the generator while engine and
exhaust area are warm.
SECTION 7 - 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 separa-
tion 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 emp-
tied before storage of 30 days or longer, as follows:
Remove all gasoline from the fuel tank.
• Start and run engine until engine stops from lack of
fuel.
• While engine is still warm, drain oil from crankcase.
Rell with recommended grade.
• Remove spark plugs and pour about 1/2 ounce (15
ml) of engine oil in the cylinders. Cover spark plug
hole with rag. Pull the recoil starter a couple times to
lubricate the piston rings and cylinder bore.
Install and tighten spark plugs. Do not connect
spark plug wires.
• Clean the generator outer surfaces. Check that cool-
ing air slots and openings on generator are open and
unobstructed.
• Store the unit in clean, dry place.
• Do not store gasoline from one season to another.
• Replace the gasoline can if it has started 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.
SECTION 8 - WARRANTY
We welcome warranty repair and apologize to you for
being inconvenienced. Any Authorized Service Dealer
may perform warranty repairs. Consumer sales are war-
ranted for one (1) year. Most warranty repairs are handled
routinely, but sometimes requests for warranty service
may not be appropriate. For example, warranty service
would not apply if equipment damage occurred because
of misuse, lack of routine maintenance, shipping, han-
dling, warehousing or improper installation. Similarly, the
warranty is void if the manufacturing date or the serial
number on the portable generator has been removed or
the equipment has been altered or modied. During the

warranty period, the Authorized Service Dealer, at its option, will repair or replace any part that, upon examina-
tion, is found to be defective under normal use and service. This warranty will not cover the following repairs
and equipment:
• REGULAR WEAR: Outdoor Power Equipment, as with all mechanical devices, need periodic part(s) service and
replacement to perform as designed. This warranty will not cover repair when normal use has exhausted the
lifetime of a part(s) or engine.
• INSTALLATION AND MAINTENANCE: This warranty does not cover the generator or parts when they have been
subjected to improper or unauthorized use, assembly, altered, modied, or damage due to misuse, negligence,
accident, overloading, over-speeding, improper maintenance, repair or storage so as, in our judgment, to ad-
versely aect its performance and reliability. This warranty also does not cover regular maintenance and parts
such as air lters, adjustments, fuel system cleaning and obstruction (due to chemical, dirt, carbon, lime, and so
forth).
• OTHER EXCLUSIONS: This warranty excludes wearing parts such as o-rings, lters, etc., or malfunctions result-
ing from accidents, abuse, modications, alterations, or improper servicing or freezing or chemical deteriora-
tion; Damaged related to rodent and/or insect infestation.
Accessory parts such as starting batteries, generator adapter cord sets and storage covers are excluded from
the product warranty. This warranty excludes used, reconditioned, and demonstration equipment, equipment
used for prime power in place of utility power, equipment used in life support applications, and failures due to
acts of God and other force majeure events beyond the manufacturers control, such as collision, theft, vandal-
ism, riot or wars, nuclear holocaust, re, freezing, lightning, earthquake, windstorm, hail, volcanic eruption,
water or ood, tornado or hurricane.
