Operation
Operation
Step 1: Safe Location
Before starting the portable generator there are two equally
important safety concerns regarding carbon monoxide
poisoning and fire that must be addressed.
Operation Location to Reduce the Risk of
Carbon Monoxide Poisoning
The engine exhaust of all fossil fuel burning equipment,
such as a portable generator, contains carbon monoxide,
a poisonous gas that will kill you in minutes. You cannot
smell it, see it, or taste it. Even if you do not smell
exhaust fumes, you could still be exposed to carbon
monoxide gas.
By law in many jurisdictions it is required to have a carbon
monoxide alarm in operating condition in your home.
A carbon monoxide alarm is an electronic device that
detects hazardous levels of carbon monoxide. When there
is a buildup of carbon monoxide, the alarm will alert the
occupants by flashing visual indicator light and alarm.
Smoke alarms cannot detect carbon monoxide gas.
DANGER! Engine exhaust contains carbon
monoxide, a poisonous gas that will kill you in
minutes. You cannot smell it, see it, or taste it.
Even if you do not smell exhaust fumes, you could still be
exposed to carbon monoxide gas.
• Operate portable generator only outdoors, at least
20 ft. (6.1 m) from occupied spaces with exhaust
pointed away to reduce the risk of carbon monoxide
accumulating.
• Install battery-operated carbon monoxide alarms or
plug-in carbon monoxide alarms with battery back-up
according to the manufacturer’s instructions. Smoke
alarms cannot detect carbon monoxide gas.
• Do not run portable generator inside homes, garages,
basements, crawlspaces, sheds, or other partially-
enclosed spaces even if using fans or opening doors
and windows for ventilation. Carbon monoxide can
quickly build up in these spaces and can linger for
hours, even after this product has shut off.
If you start to feel sick, dizzy, weak, or your homes carbon
monoxide alarm sounds while using this product, get to
fresh air right away. Call emergency services. You may
have carbon monoxide poisoning.
Carbon Monoxide Alarm(s)
Install carbon monoxide alarm
inside your home. Without
working carbon monoxide
alarms, you will not realize you
are getting sick and dying from
carbon monoxide poisoning.
To better educate yourself about all carbon monoxide risks,
go to www.takeyourgeneratoroutside.com.
Prevent Carbon Monoxide (CO) Poisoning
• Use outdoors at least 20 ft. (6.1 m) from any home.
• Point exhaust away from all homes and occupied spaces.
• Install CO alarms inside your home.

• Portable generator must be at least 5ft. (1.5m) from
any structure, overhang, trees, shrubs, or vegetation over
12 in. (30.5 cm) in height.
• Do not place portable generator under a deck or
other type of structure that may confine airflow.
Smoke alarm(s) must be installed and maintained
indoors according to the manufacturer’s instructions/
recommendations.
• Carbon monoxide alarms cannot detect smoke.
• Do not place portable generator in manner other than
shown.

Step 2: Oil and Fuel
1. Move generator outdoors to a flat, level surface.
2. Clean area around oil fill and remove oil fill cap/
dipstick.
3. Using oil funnel (optional), slowly pour contents of
provided oil bottle into oil fill opening to the full mark
on dipstick.
NOTICE Pause to permit oil to settle. Wipe dipstick clean
each time oil level is checked. DO NOT overfill.
4. Replace and fully tighten oil fill cap/dipstick.
Fuel must meet these requirements:
• Clean, fresh, unleaded fuel with a minimum of 87
octane.
• Gasoline with an ethanol content up to 10% is
acceptable.
E10
E15
NOTICE Do not mix oil in fuel or modify engine to run on
alternate fuels. Use of unapproved fuels could damage
engine and will not be covered under warranty.
See High Altitude for 5,000 ft. (1524 m) and above.
WARNING! Fuel and its vapors are extremely
flammable which could cause burns or fire
resulting in death or serious injury.
• Do not refuel during operation.
• Do not smoke during refueling.
• Turn engine off and let it cool at least 2 minutes before
removing fuel cap.
• Fill fuel tank outdoors. Keep fuel away from sparks, open
flames, pilot lights, heat, and other ignition sources.
Check fuel lines, tank, cap and fittings frequently for
cracks or leaks. Replace if necessary.
1. Slowly remove fuel cap to relieve pressure in tank.
2. Slowly add unleaded fuel to fuel tank. Be careful not
to fill above bottom lip. This allows adequate space
for fuel expansion.
3. Install fuel cap and let any spilled fuel evaporate
before starting engine.
High Altitude
At altitudes over 5,000 ft. (1524 m), a minimum
85octane fuel 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 Briggs & Stratton dealer for high
altitude adjustment information. Operation of the engine at
altitudes below 2,500 ft. (762 m) with the high altitutde
kilt is not recommended.
Transporting
When transporting equipment with a vehicle or trailer, turn
fuel shutoff valve to off (0) position. Do not tip engine or
equipment at an angle which causes fuel to spill.

Up to 30A 10 8
2. Follow cord safety instructions.
3. Install carbon monoxide alarm(s).
4. When operating generator with extension cords, make
sure it is located in an open, outdoor area, at least
20 ft. (6.1 m.) from occupied spaces with exhaust
pointed away.
5. Extension cords running directly into home, powering
indoor items IS NOT RECOMMENDED.
DANGER! Engine exhaust contains carbon
monoxide, a poisonous gas that will kill you in
minutes. You cannot smell it, see it, or taste it.
Even if you do not smell exhaust fumes, you could still be
exposed to carbon monoxide gas.
• Extension cords running directly into the home
increase your risk of carbon monoxide poisoning
through openings.
• If an extension cord running directly into the home is
used to power indoor items, the operator recognizes
that this increases the risk of CO poisoning to people
inside the home and assumes that risk.
WARNING! Damaged or overloaded extension
cords could overheat, arc, and burn resulting in
death or serious injury.

Operation
120 Volt AC, 20 Amp, GFCI Duplex Receptacles
Use each receptacle to operate 120 Volt AC, single-phase,
60 Hz electrical loads requiring up to 2,400 Watts (2.4 kW)
at 20 Amps of current.
Ground Fault Protection
The duplex receptacles are equipped with Ground Fault
Circuit Interrupter (GFCI) protection. The GFCI protects
against electrical shock that may be caused if your body
becomes a path which electricity travels to reach ground.
When protected by a GFCI, one may still feel a shock, but
the GFCI is intended to cut current off quickly enough
so that a person in normal health should not suffer any
serious electrical injury.
WARNING! Generator voltage could cause
electrical shock or burn resulting in death or
serious injury. Contact with the hot and neutral
conductor at the same time could cause electrical shock
or burn, even if the circuit is GFCI protected.
Testing the GFCI
With the engine running, test your GFCI outlet prior to
each use, as follows:
• Push the “Test” button. The “Reset” button should
pop out, which should allow no power to reach the
outlet.
• Press the “Reset” button firmly until it is fully in
place and locks in that position. If the GFCI outlet
does not reset properly, do not use the outlet. Call or
take your generator to a local service center.
• If the GFCI trips by itself at any time, reset and test
the outlet.
120 Volt AC, 30 Amp, Travel Trailer Receptacle
Use a NEMA TT–30 plug with this receptacle. Connect
a 3–wire travel trailer cord set rated for 125 Volt AC loads
at 30 Amps to the plug. The generator’s travel trailer
receptacle is not protected by a GFCI.
This receptacle powers 120 Volt AC, 60 Hz, single phase
travel trailer loads requiring up to 3,500 watts (3.5 kW) of
power at 29.1 Amps.

Operation
Generator Capacity
To make sure your generator can supply enough running
watts and starting watts for the items you will power at the
same time, follow these three simple steps:
1. Select the items you will power at the same time. See
following list for typical wattages.
* Typical wattages listed are approximate only. Check tool
or appliance for actual wattage.
** The momentary electrical current the generator can
provide to start electric motors, per Briggs & Stratton
standard 628K. It does not represent the power required
to continuously run electrical loads. It is the maximum
current that can momentarily be supplied when starting a
motor, multiplied by the generator’s rated voltage.
2. Total the running watts. This is the amount of power
your generator must produce to keep your items
running. See following example:
Example
Total running watts = 2125
Highest starting watts = 2100
Total generator watts required = 4225
3. Estimate the starting watts you will need. Because
not all motors start at the same time, total starting
wattage can be estimated by adding only the item
with the highest additional starting watts requirements
to the total running watts from step 2.
Power Management
To manage generator power, sequentially add loads as follows:
1. With nothing connected to generator, start the engine
outdoors.
2. Plug in and turn on the first load, preferably the
largest load you have.
3. Permit the generator output to stabilize (engine runs
smoothly and attached device operates properly).
4. Plug in and turn on the next load.
5. Again, permit the generator to stabilize.
6. Repeat steps 4 and 5 for each additional load.
Never add more loads than the generator capacity. Take
special care to consider starting loads in generator capacity.
CO Detection
Carbon Monoxide (CO) Shutdown System
CO Detection automatically shuts down the engine when
harmful levels of carbon monoxide accumulate around the
generator or a CO Detection fault occurs. After shutdown,
the CO Detection indicator light will blink for at least five
minutes per the chart below.
CO Detection DOES NOT replace carbon monoxide alarms.
Install battery-powered carbon monoxide alarm(s) in your
home. Don’t run generator in enclosed areas.

Storage
Storage
If storing the unit for more than 30days, use the following
guidelines to prepare it for storage.
Long Term Storage Instructions
1. Clean the generator as outlined in Cleaning.
2. Change engine oil while engine is still warm, drain oil
from crankcase. Refill with recommended grade. See
Changing Engine Oil.
3. Treat or drain fuel from generator as fuel can become
stale when stored over 30 days.
Stale fuel causes acid and gum deposits to form in the
fuel system or on essential carburetor parts. To keep fuel
fresh, use a fuel stabilizer.
There is no need to drain gasoline from the engine if a
fuel stabilizer is added according to instructions. Run the
engine for 2 minutes to circulate the stabilizer throughout
the fuel system before storage.
If gasoline in the engine has not been treated with a fuel
stabilizer, it must be drained into an approved container.
Then run the engine until it stops from lack of fuel.
The use of a fuel stabilizer in the storage container is
recommended to maintain freshness.
WARNING! Fuel and its vapors are extremely
flammable and explosive which could cause
burns, fire or explosion resulting in death or
serious injury.
• When storing fuel or equipment with fuel in tank, store
away from furnaces, stoves, water heaters, clothes dryers
or other appliances that have pilot light or other ignition
source because they could ignite fuel vapors.
• When draining fuel, turn generator engine off and let it
cool at least 2 minutes before removing fuel cap. Loosen
cap slowly to relieve pressure in tank. Drain fuel tank
outdoors. Keep fuel away from sparks, open flames, pilot
lights, heat, and other ignition sources.
• Check fuel lines, tank, cap and fittings frequently for
cracks or leaks. Replace if necessary.
4. Store generator in clean, dry area and cover with a
suitable protective cover that does not retain moisture.

Power Ratings: The gross power rating for individual gasoline engine models is labeled in accordance with SAE (Society of Automotive
Engineers) code J1940 Small Engine Power & Torque Rating Procedure, and is rated in accordance with SAE J1995. Torque values are
derived at 2600 RPM for those engines with “rpm” called out on the label and 3060 RPM for all others; horsepower values are derived
at 3600 RPM. The gross power curves can be viewed at www.BRIGGSandSTRATTON.COM. Net power values are taken with exhaust
and air cleaner installed whereas gross power values are collected without these attachments. Actual gross engine power will be higher
than net engine power and is affected by, among other things, ambient operating conditions and engine-to-engine variability. Given the
wide array of products on which engines are placed, the gasoline engine may not develop the rated gross power when used in a given
piece of power equipment. This difference is due to a variety of factors including, but not limited to, the variety of engine components
(air cleaner, exhaust, charging, cooling, carburetor, fuel pump, etc.), application limitations, ambient operating conditions (temperature,
humidity, altitude), and engine-to engine variability. Due to manufacturing and capacity limitations, Briggs & Stratton may substitute an
engine of higher rated power for this engine.
