a current licensed electrician. The connection must
isolate the generator power from the utility power and
must comply with all applicable laws and electrical
codes.
Portable Generator Location
Before starting the portable generator there are two
equally important safety concerns regarding carbon
monoxide (CO) poisoning and fire that must be
addressed.
NOTICE Satisfying the RISK OF CARBON
MONOXIDE POISONING location requirements may
not satisfy the fire location requirements. Satisfying the
RISK OF FIRE location requirements may not satisfy
the CARBON MONOXIDE POISONING location
requirements.
Operation Location of Portable Generator to
REDUCE THE RISK OF CARBON MONOXIDE
POISONING
All fossil fuel burning equipment, such as a portable
generator, contains carbon monoxide (CO) gas in the
engine exhaust, a poisonous gas that could 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. The following must
be completed prior to starting the portable generator
engine:
• By law it is required in many states to have a
Carbon Monoxide (CO) alarm (A) in operating
condition in your home. Install/maintain battery-
operated carbon monoxide alarms or plug-in
carbon monoxide alarms with battery back-up
according to the manufacturer’s instructions. A
CO alarm is an electronic device that detects
hazardous levels of CO. When there is a buildup of
CO, the alarm will alert the occupants by flashing
visual indicator light and alarm. Smoke alarms
cannot detect CO gas.
A
• Operate this product ONLY outside far away from
windows, doors and vents to reduce the risk of
carbon monoxide gas from accumulating and
potentially being drawn towards occupied spaces.
• DO NOT run this product 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.
• Your neighbor(s) home may be exposed to the
engine exhaust from your portable generator and
must be considered when deciding on a location
for the safe operation of your portable generator.
• ALWAYS place this product downwind and point

Don’t Overload Generator
Capacity
You must make sure your generator can supply
enough rated (running) and surge (starting) watts for
the items you will power at the same time. Follow these
simple steps:
1. Select the items you will power at the same time.
2. Total the rated (running) watts of these items.
This is the amount of power your generator must
produce to keep your items running. See Wattage
Reference Guide.
3. Estimate how many surge (starting) watts you will
need. Surge wattage is the short burst of power
needed to start electric motor-driven tools or
appliances such as a circular saw or refrigerator.
Because not all motors start at the same time,
total surge watts can be estimated by adding only
the item(s) with the highest additional surge watts
to the total rated watts from step 2.
Example:
Total Rated (Running) Watts = 1555
Highest Additional Surge Watts = 600
Total Generator Output Required = 2155
Power Management
To prolong the life of your generator and attached
devices, it is important to take care when adding
electrical loads to your generator. There should be
nothing connected to the generator outlets before
starting its engine. The correct and safe way to
manage generator power is to sequentially add loads
as follows:
1. With nothing connected to the generator, start the
engine as described in this manual.
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 surge loads in generator
capacity, as described above.
* Wattages listed are approximate only. Check tool or
appliance for actual wattage.

Maintenance
Maintenance Schedule
Follow the hourly or calendar intervals, whichever
occurs first. More frequent service is required when
operating in adverse conditions noted below.
1Service more often under dirty or dusty conditions.
General Recommendations
Regular maintenance will improve the performance
and extend the life of the generator. See any
authorized dealer for service.
The generator’s warranty 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.
NOTICE Improper treatment of generator could
damage it and shorten its life.
• NEVER operate generator without protective housing or
covers to assure proper cooling.
Some adjustments will need to be made periodically to
properly maintain your generator.
All service and adjustments should be made at least
once each season. A new spark plug and clean
air filter assure proper fuel-air mixture and help
your engine run better and last longer. Follow the
requirements in the Maintenance Schedule chart
above.
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.
NOTICE DO NOT use water or other liquids to clean
generator. Liquids can enter engine fuel system,
causing poor performance and/or failure to occur. In
addition, if liquid enters generator through cooling air
slots, some of the liquid will be retained in voids and
cracks of the rotor and stator winding insulation. Liquid
and dirt buildup on the generator internal windings will
eventually decrease the insulation resistance of these
windings.
Cleaning
Daily or before use, look around and underneath
the generator for signs of oil or fuel leaks. Clean
accumulated debris from inside and outside the
generator. Keep the linkage, spring and other engine
controls clean. Keep the area around and behind
the muffler free from any combustible debris. Inspect
cooling air slots and openings on generator. These
openings must be kept clean and unobstructed.
Engine parts should be kept clean to reduce the risk of
overheating and ignition of accumulated debris:
• Use a damp cloth to wipe exterior surfaces clean.
NOTICE Improper treatment of generator could
damage it and shorten its life.
• DO NOT expose generator to excessive moisture, dust,
dirt, or corrosive vapors.
• DO NOT insert any objects through cooling slots.
• Use a soft bristle brush to loosen caked on dirt or
oil.
• Use a vacuum cleaner to pick up loose dirt and
debris.

Storage
The generator should be started at least once every
seven days and allowed to run at least 30 minutes. If
this cannot be done and you must store the unit for
more than 30 days, use the following guidelines to
prepare it for storage.
Generator Storage
1. Clean the generator as outlined in Cleaning.
2. Check that cooling air slots and openings on
generator are open and unobstructed.
Long Term Storage Instructions
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 Briggs & Stratton® Advanced Formula
Fuel Treatment & Stabilizer, available wherever Briggs
& Stratton genuine service parts are sold.
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. 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.
Change Engine Oil
While engine is still warm, drain oil from crankcase.
Refill with recommended grade. See Changing Engine
Oil.
Other Storage Tips
1. DO NOT store fuel from one season to another
unless it has been treated as described in Long
Term Storage Instructions.
2. Replace fuel container if it starts to rust. Rust and/
or dirt in fuel can cause problems if it’s used with
this unit.
3. Cover unit with a suitable protective cover that
does not retain moisture.
4. Store generator in clean, dry area.
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.
