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.
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 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 alarm 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.
WARNING
Generator voltage could cause
electrical shock or burn resulting in death or
serious injury.
Use approved transfer equipment to prevent backfeed by
isolating generator from electric utility workers.
When using generator for backup power, notify utility
company.
DO NOT touch bare wires or receptacles.
DO NOT use generator with electrical cords which are
worn, frayed, bare or otherwise damaged.
DO NOT operate generator in the rain or wet weather.
DO NOT handle generator or electrical cords while
standing in water, while barefoot, or while hands or feet
are wet.
DO NOT allow unqualified persons or children to operate
or service generator.

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 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.
** Per Briggs & Stratton 628K, Starting Watts
represents the momentary electrical current the
generator can provide to start electric motors.
Starting Watts does not represent the power
required to continuously run electrical loads.
Starting Watts 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 = 2355
Highest starting watts = 2000
Total generator watts required = 4355
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 surge loads in generator
capacity.

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.
Emissions Control
Maintenance, replacement, or repair of the
emissions control devices and systems may
be performed by any non-road engine repair
establishment or individual. However, to obtain
”no charge” emissions control service, the work must
be performed by a factory authorized dealer. See the
Emissions Warranty.
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.

Oil
Oil Recommendations
We recommend the use of Briggs & Stratton Warranty
Certified oils for best performance. Other high-quality
detergent oils are acceptable if classified for service
SF, SG, SH, SJ or higher. DO NOT use special
additives.
Outdoor temperatures determine the proper oil
viscosity for the engine. Use the chart to select the
best viscosity for the outdoor temperature range
expected.
* Below 40°F (4°C) the use of SAE 30 will result in hard
starting.
** Above 80°F (27°C) the use of 10W30 may cause
increased oil consumption. Check oil level more frequently.

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
Clean the generator as outlined in Cleaning.
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
hroughout 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.
