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 the table
on the right.
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.

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 it's 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.

ENGINE TECHNICAL aNFORMATtON
This is a single cylinder, overhead valve(OHV), air
cooled engine, it is a low emissions engine.
in the State of California, Model Series 210000
engines are certified by the California Air Resources
Board to meet emissions standards for 250 hours.
Such certification does not grant the purchaser, owner
or operator of this engine any additional warranties
with respect to the performance or operational life of
this engine. The engine is warranted solely according
to the product and emmisions warranties stated
elsewhere in this manual.
Power Ratings
The power ratings for an individual engine model are
initially developed by starting with SAE (Society of
Automotive Engineers) code J1940 (Small Engine
Power & Torque Rating Procedure) (Revision 2002-
05). Given both the wide array of products on which
our engines are placed, and the variety of
environmental issues applicable to operating the
equipement, it may be that the engine you have
purchased will not develop the rated horsepower when
used in a peice of power equipment (actual "on-site"
power). This difference is due to a variety of factors
including, but not limited to, the following: differences
in altitude, temperature, barometric pressure, humidity,
fuel, engine lubrication, maximum governed engine
speed, individual engine to engine variability, design of
the particular peice of power equipment, the manner in
which the engine is operated, engine run-in to reduce
friction and clean out of combustion chambers,
adjustments to the valves and carburetor, and other
factors. The power ratings may also be adjusted
based on comparisons to other similar engines
utilizedin similar applications, and will thereforenot
necessarily match the values derived using the
foregoing codes.

SERVICE DATES
Change oil after the first (5) operating hours and every 50 hours or every year, whichever occurs first, thereafter.
Change sooner when operating under dirty or dusty conditions.
Replace 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 Sears 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 generator as instructed in this manual.
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. Follow the requirements in the
"Maintenance Schedule" chart above.
NOTE: Once a year you should clean or replace the
spark plug and replace the air filter. A new spark plug
and clean air filter assure proper fuel-air mixture and
help your engine run better and last longer.
EMISSION CONTROL
Maintenance, replacement or repair of the emission
control devices and systems may be performed by any
non-road engine repair establishment or individual.
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.
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 of the water
will be retained in voids and cracks 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.
Generator Cleaning
Daily or before use, clean accumulated debris from
generator. Keep linkage, spring and controls clean.
Keep area around and behind muffler free from any
combustible debris.
Generator 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.
CAUTION
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, oil, etc.
• Use a vacuum cleaner to pick up loose dirt and debris.
Battery Maintenance
Other than trickle charging, described elsewhere, no
maintenance is required for the battery. Keep the
battery and terminals clean and dry.
IMPORTANT: Battery charging should be performed
in a dry location, such as inside a garage.

NOTE: You can purchase new air cleaner elements by
calling 1-800-366-PART.
Carburetor
if you think your carburetor needs adjusting, see your
nearest Sears service center. Engine performance
may be affected at altitudes above 3000-5000 feet.
For operation at higher elevations, contact your
nearest Sears service center.
CJean Spark Arrester Screen
The engine exhaust muffler has a spark attester
screen. Inspect and clean the screen every 100 hours
of operation or once each year, whichever comes first.
NOTE: You can purchase a new spark attester screen
by calling 1-800-366-PART.
If you use your generator on any forest-covered, brush-
covered, or grass-covered unimproved land, it must
have a spark attester. The spark arrester must be
maintained in good condition by the owner/operator.

WARNING
DO NOT touch hot surfaces.
Allow equipment to cool before touching.
The generator must be at least 5 feet from structures having
combustible walls and/or other combustible materials.
Keep at least 3 feet of clearance on all sides of generator
for adequate cooling, maintenance and servicing.
In the State of California a spark arrester is required by law
(Section 4442 of the California Public Resources Code).
Other states may have similar laws. Federal laws apply on
federal lands. If you equip the muffler with a spark arrester,
it must be maintained in effective working order.
Clean and inspect the spark attester as foltows:
1. To remove muffler heat shield from muffler, remove
four screws that connect guard to muffler bracket.
2. Remove four screws that attach spark attester
screen.

guidetoprepareitforstorage.
Long Term Storage _nstructions
it is important to prevent gum deposits from forming in
essential fuel system parts, such as the carburetor,
fuel filter, 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 fuel 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. Follow
these instructions:
WARNING
WHEN STORING FUEL OR EQUIPMENTWITH FUEL IN
TANK
Store away from furnaces, stoves, water heaters, clothes
dryers or other appliances that havepilot light or other
ignition source because they can ignite fuel vapors.
WHEN DRAiNiNG FUEL
Turn generator OFF and let itcool 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.
DO NOT light a cigarette or smoke.
Protect Fuet System
1. Remove all gasoline from fuel tank to prevent gum
deposits from forming on these parts and causing
possible malfunction of engine.
2. Run engine until engine stops from lack of fuel.
Change OH
While engine is still warm, drain oil from crankcase.
Refill with recommended grade.
OHCylinder Sore
• Remove spark plug and pour about 1 ounce (30ml)
of clean engine oil into the cylinder.
• Install spark plug and crank slowly to distribute oil.
WARNING
NEVER crank enqine with spark plug removed.
Generator
1. Clean generator as outlined in "Generator Cleaning".
2. Check that cooling air slots and openings on
generator are open and unobstructed.
Other Storage Tips
1. DO NOT store fuel from one season to another.
2. Replace fuel can if it starts to rust. Contaminated
fuel will cause engine problems.
3. If possible, store unit indoors and cover it to give
protection from dust and dirt. BE SURE TO
EMPTY FUEL TANK.
4. Cover unit with a suitable protective cover that
does not retain moisture.
5. Store generator in clean, dry area.
