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 INFORMATION
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

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.

ENGINE MAINTENANCE
WARNING
WHEN ADJUSTING OR MAKING REPAIRS TO YOUR
GENERATOR
Disconnect the spark plug wire from the spark plug and
place the wire where it cannot contact spark plug.
WHEN TESTING FOR ENGINE SPARK
Use approved spark plug tester.
DO NOT check for spark with spark plug removed,
Oil Recommendations
NOTE: When adding oil to the engine crankcase, use
only high quality detergent oil rated with API service
classification SF, SG, SH, SJ or higher. DO NOT use
special additives.
1. Choose a viscosity according to the following table:
J
100
C 30 2Q 10 0 10 20 30 40
STARTING TEMPERATURE RANGE ANTICIPATED BEFORE NEXT O_L CHANGE
NOTE: Synthetic oil meeting ILSAC GF-2, API
certification mark and API service symbol with "SJ/CF
ENERGY CONSERVING" or higher, is an acceptable
oil at all temperatures. Use of synthetic oil does not
alter required oil change intervals.
* The use of multi-viscosity oils (5W-30, 10W-30, etc.)
in temperatures above 40°F (4°C) will result in higher
than normal oil consumption. When using a multi-
viscosity oil, check oil more frequently.
** If using SAE 30 oil in temperatures below 40°F
(4°C), it will result in hard starting and possible engine
bore damage due to inadequate lubrication.
Checking Oil Levet
Oil level should be checked prior to each use or at least
every 5 hours of operation. Keep oil level maintained.
1. Make sure generator is on a level surface.
2. Remove oil fill cap and wipe clean with cloth.
3. Verify{ oil is at the point of overflowing at oil fill
opening.
Adding Engine Oim
1. Make sure generator is on a level surface.
2. Check oil level as described in "Checking Oil Level".
3. If needed, slowly pour oil into oil fill opening to the
point of overflowing at oil fill cap.
Changing Engine OH
Change the oil after the first 5 hours of operation.
Change oil every 50 hours thereafter. If you are using
your generator under extremely dirty or dusty conditions,
or in extremely hot weather, change the oil more often.
CAUTION
Used motor oil has been shown to cause skin cancer in
certain laboratory animals.
Thoroughly wash exposed areas with soap and water.
KEEP OUT OF REACH OF CHILDREN.
DON'T POLLUTE. CONSERVE
RESOURCES. RETURN USED OIL TO
COLLECTION CENTERS.
Change the oil while the engine is still warm from
running, as foitows:
1. Make sure unit is on a level surface.
2. Disconnect the spark plug wire from the spark
plug and place the wire where it cannot contact
spark plug.

a suitable container.
5. Reinstall oil drain plug and tighten securely.
Remove oil fill cap.
6. Slowly pour oil (about 28 oz.) into oil fill opening to
the point of overflowing at oil fill cap. DO NOT
overfill.
7. Reinstall oil fill cap. Finger tighten cap securely.
8. Wipe up any spilled oil.
CJeantRep_ace Spark P_ug
Change the spark plug every 100 hours of operation
or once each year, whichever comes first. This will
help your engine to start easier and run better.
1. Clean area around spark plug.
2. Remove and inspect spark plug.
3. Check electrode gap with wire feeler gauge and set
spark plug gap to 0.030 inch (0.76mm) if necessary.

commercial solvent.
4. Reattach screen and muffler guard.
Air Coo_ing System
Over time debris may accumulate in cylinder cooling
fins and cannot be observed without partial engine
disassembly. For this reason, we recommend you
have an authorized Sears service dealer clean the
cooling system per recommended intervals (see
"Maintenance Schedule" on page 13). Equally
important is to keep top of engine free from debris.
See "Generator Cleaning". CLEAN
DO NOT touch hot surfaces and avoid hot exhaust gases.
Allow equipment to cool before touching.
Keep at least 5 ft. (152 cm) clearance on all sides of
generator including overhead.
Reflective exhaust heat may damage fuel tank causing fire.
Code of Federal Regulation (CFR) Title 36 Parks,
Forests, and Public Property require equipment powered
by an internal combustion engine to have a spark
arrester, maintained in effective working order, complying
to USDA Forest service standard 5100-1C or later
revision. In the State of California a spark arrester is
required under section 4442 of the California Public
resources code. Other states may have similar laws.

thiscannotbedoneandyoumuststoretheunitfor
morethan30days,usethefollowinginformationasa
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 Fue_ System
Fuel Additive:
If adding a fuel additive, fill the fuel tank with fresh
fuel. If only partially filled, air in the tank will promote
fuel deterioration during storage. Engine and fuel can
be stored up to 24 months with additive.
• Add fuel additive following manufacturer's
instructions.
• Run the engine outdoors for several minutes to be
sure that treated fuel has replaced the untreated
fuel in the carburetor.
If fuel additive is not used, remove all fuel from tank
and run engine until it 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.
.
DO NOT place a storage cover over a hot generator.
Let equipment cool for a sufficient time before placing
the cover on the equipment.
Store generator in clean, dry area.
