BEFORE STARTING THE
GENERATOR
Add Engine Oil
NOTE: A 20 hour break-in period is required. Replace
engine oil and oil filter after the first 20 hours. Do Not
use synthetic oil during the break-in period.
NOTE: When adding oil to the engine crankcase in
the future, use only high quality detergent oil rated
with API service classification SF or higher. Use no
special additives.
Select the oil's viscosity grade according to your
expected operating temperature:
i[tlYivj
Single
Grade
Multi • •
Grade • •
-20 -10 0 10 20 30 40°C
-4 14 32 50 68 86 104°F
NOTE: For operating temperatures above 90°F,
synthetic oil is recommended. Synthetic oil will last
longer and protect the engine better in high
temperature conditions.
Although multi-viscosity oils (10W40, 10W30, etc.)
improve starting in cold weather, these multi-viscosity
oils will result in increased oil consumption when used
above 32°F. Check your engine oil level more
frequently to avoid possible damage from running low
on oil.
To add oil:
• Place generator on a level surface.
• Clean area around oil fill cap and dipstick. Remove
oil fill cap and dipstick.
• Wipe dipstick clean.
• Slowly fill engine with oil through the oil fill opening
until it reaches the upper line on the dipstick. An oil
spout is supplied that can be attached to the oil
bottle. Always check the oil level with the dipstick
plugged into position. Stop filling occasionally to
check oil level. Do Not overfill!
• Install dipstick. Install oil fill cap and hand tighten
securely.
• Check engine oil level before starting each time
thereafter. Refill if below the lower line on the
dipstick.

• Install fuel cap and wipe up any spilled gasoline.
IMPORTANT: If the generator stops because it ran
out of fuel, turn key switch to "Stop" position so that
the battery is not depleted.
IMPORTANT: It is important to prevent gum deposits
from forming in fuel system parts during storage, such
as the carburetor, fuel filter, fuel hose or tank. Also,
alcohol-blended fuels (called gasohol, ethanol or
methanol) can attract moisture, which leads to
formation of acids during storage. Acidic gas can
damage the fuel system while in storage. To avoid
engine problems, the fuel system should be emptied
before storage of 30 days or longer. See "Storage" on
page 16. Never use engine or carburetor cleaner
products in the fuel tank or permanent damage may
Occur.
HOW TO USE YOUR GENERATOR
If you have any problems operating your generator,
please call the generator helpline at 1-800-222-3136.
Grounding The Generator
The National Electrical Code requires that the
frame and external electrically conductive parts of
this generator be properly connected to an
approved earth ground. Local electrical codes may
also require proper grounding of the unit. For that
purpose, a grounding lug is provided on the base of
the cradle.
TO START THE ENGINE
CAUTION! Never start or stop engine with electrical
devices plugged into the receptacles AND devices
turned ON.
• Unplug all electrical loads from generator
receptacles before starting the engine.
• Make sure the unit is in a level position.
• Open the fuel shut-off valve.
\
Fuel Valve is shown
in the On position
Pull the choke knob to close. If the engine is warm,
or the ambient temperature is high, pull the choke
knob half-way, or keep it fully open.
\
FUEL TANK
J
Generally, connecting a No. 12 AWG (American Wire
Gauge) stranded copper wire to the grounding lug and
to an earth-driven copper or brass grounding rod
(electrode) provides adequate protection against
electrical shock. However, local codes may vary
widely. Consult with a local electrician for
grounding requirements in your area.
Proper grounding of generator will help prevent
electrical shock in the event of a ground fault
condition in the generator or in connected electrical
devices. Proper grounding also helps dissipate static
electricity, which often builds up in ungrounded
devices.
Connecting Electrical Loads
• Let engine stabilize and warm up for a few minutes
after starting.
• Plug in and turn on the desired 120 Volt or
240 Volt, single phase, 60 Hz electrical loads.
• Do Not connect 240 Volt loads to 120 Volt
receptacles.
• Do Not connect 3-phase loads to the generator.
• Do Not connect 50 Hz loads to the generator.
• Add up the rated watts (or amps) of all loads to be
connected at one time. This total should not be
greater than (a) the rated wattage/amperage
capacity of the generator or (b) circuit breaker
rating of the receptacle supplying the power. See
"Don't Overload the Generator" on page 12.
Close /
/
Turn the key switch to the "Start" position.
IMPORTANT: Do Not operate the electric starter
continuously for more than 5 seconds, even if the
engine does not start. Extended cranking can damage
the starter motor.
NOTE: If engine fails to start, set the key to the "Run"
position and wait for about 10 seconds before retrying.
IMPORTANT: Never turn the key switch to the "Start"
position while the engine is running. You could
damage the starter motor.
• When the engine starts, gradually open choke by
pushing the choke knob and keep it fully opened
while running.
IMPORTANT: Do Not overload the generator. Also,
Do Not overload individual panel receptacles. These
outlets are protected against overload with push-to-
reset-type circuit breakers. If amperage rating of any
circuit breaker is exceeded, that breaker opens and
electrical output to that receptacle is lost. Read "Don't
Overload the Generator" on page 12 carefully.
STOPPING THE ENGINE
• Unplug (or turn OFF) all electrical loads connected
to generator panel receptacles. Never start or
stop engine with devices plugged in and turned
on.
• Let engine run at no-load for 30 seconds to
stabilize the internal temperatures of engine and
generator.
• Turn the key switch to the "Stop" position.
• Close the fuel valve.
STOPPING THE ENGINE WITH THE
FUEL VALVE
This procedure eliminates fuel from the carburetor.
Use this method to stop the generator if you plan to
store the generator over a long period. Fuel will clog
the internal passages of carburetor if allowed to
remain for an extended period.
• Unplug (or turn OFF) all electrical loads connected
to generator panel receptacles. Never start or
stop engine with devices plugged in and turned
on.
• Let engine run at no-load for 30 seconds to
stabilize the internal temperatures of engine and
generator.
• Close the fuel valve while the engine is running
and wait until the engine stops.
Set the key switch to the "Stop" position after
stopping the engine. Failure to put the key
switch into the "Stop" position will deplete the
battery.
If the Engine Will Not Start
Perform the following checks if your engine does not
start:
1. Do you have enough gasoline?
Check to make sure you have fuel in the gas tank.
2. Is the fuel valve open?
Check to make sure the fuel valve is open. If it is
closed, open it.
3. Is there enough compression?
Check to see if either spark plug is loose. If so,
tighten it.
4. Is there enough oil?
You unit comes equipped with a low oil pressure
shutdown system. If there is not enough oil in your
engine it will not start. Fill the engine with oil to the
proper level.
5. Is the spark plug wet with gasoline?
• Apply full choke and crank the engine for 2 or
3 seconds. Remove the plug and check to see if
the electrode is wet. If the electrode is wet, fuel is
well supplied to your engine.
• If the electrode is dry, check to find where the
fuel is restricted. (Check the fuel intake of the
carburetor and fuel strainer intake.)
• In case the engine does not start with well
supplied fuel, try using fresh fuel.
6. Is there a strong spark across the electrode?
,_ WARNING! Wipe off any spilled gasoline
before checking the spark plug. Place spark
plug as far away from the spark plug hole as
possible. Do Not hold spark plug by hand when
checking.
• Remove the spark plug and connect it to the
plug cap. Ground spark plug against engine
body. Turn key switch to "Start" position.
Observe strength of spark.
• Repeat above step with a new spark plug if
the spark is weak or there is no spark.
• The ignition system is faulty if there is no
spark with a new spark plug. Take your unit to
your nearest Sears service center.
7. Is your battery well charged?
• Check the battery as it may be discharged
and unable to operate the electric starter.
Consult your nearest Sears service center.

DON'T OVERLOAD YOUR
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.

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 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.

GENERAL MAINTENANCE
RECOMMENDATIONS
The generator 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.
Some adjustments will need to be made periodically to
properly maintain the generator.
All adjustments in the Service and Adjustments
section of this manual should be made at least once
each season. Follow the requirements in the
"Maintenance Schedule" chart on page 13.
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.
_ CAUTION! Never insert any object or tool
through the air cooling slots, even if the engine
is not running.
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 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.
To Clean the Generator
• Use a damp cloth to wipe exterior surfaces clean.
• A soft, bristle brush may be used to loosen caked
on dirt, oil, etc.
• A vacuum cleaner may be used to pick up loose
dirt and debris.
Low pressure air (not to exceed 25 psi) may be
used to blow away dirt. Inspect cooling air slots
and openings on the generator. These openings
must be kept clean and unobstructed.
ENGINE MAINTENANCE
_ AUTION! When working on the generator,
always disconnect negative cable from battery.
Also disconnect spark plug wires from spark
plugs and keep wires away from spark plugs.
This will prevent accidental start-up.
Checking Oil Level
See "BEFORE STARTING THE GENERATOR" on
page 7 for information on checking the oil level. The
oil level should be checked before each use, or at
least every eight hours of operation. Keep the oil
level maintained.
Changing the Oil and Oil Filter
Change the oil and filter after the first 20 hours of
operation. Thereafter, change the oil every 50
hours and replace oil filter every 200 hours. If you
are using this engine under dirty or dusty conditions,
or in extremely hot weather, change the oil more
often.
Use the following instructions to change the oil while
the engine is still warm:
1. Clean the area around the oil drain plug, remove
the plug and drain the oil completely into a suitable
container.
2. When the oil is drained, install and tighten the oil
drain plug.
3. Place a suitable container beneath the oil filter and
remove the filter.
14
4. Coat the o-ring of a new filter with engine oil. Turn
the new filter clockwise until the gasket contacts
the filter adapter, then tighten an additional
2/3 turn.
5. Fill engine with oil as described on page 7.
6. Run the engine for a minute; stop the engine and
check for oil leakage around the oil filter. Recheck
oil level.
7. When the crankcase is filled to the proper level,
install and tighten the oil fill cap.
Inspecting the Spark Plugs
Clean spark plugs every 50 hours and replace the
plugs every 500 hours of operation. Use the
recommended spark plugs gapped for 0.6mm to
0.7mm.
1. Stop the engine and pull the spark plug wires off of
the spark plugs.
2. Clean around the spark plugs and remove them
from the cylinder head.
3. Clean off carbon deposits on the spark plug
electrode using a plug cleaner or wire brush.
4. Set the spark plugs' gap to 0.6mm to 0.7mm.
Install the correctly gapped spark plugs into the
cylinder heads.
Service Air Cleaner
The engine's air cleaner is one of the most important
areas to maintain. The engine will not run properly and
will be damaged if it is run with a dirty air cleaner
system.
Clean the urethane foam element every 50 hours
of operation. Clean paper element every 50 hours
of operation and replace every 200 hours. Clean or
replace more often in dusty or dirty conditions.
CAUTION! Never run this equipment without the
complete air cleaner system installed on the engine.
Failure to do so will result in premature engine wear
and significantly reduced engine life.
• The air cleaner paper inner element and urethane
foam outer element can be removed after removing
knob and air cleaner cover. When installing, set the
paper element and urethane foam on the air
cleaner base. Check that the grommet is in
position, and then install the cover with the knob
tightened securely.
Paper Element
• Clean by tapping gently to remove dirt and blow off
dust. Never use oil. Clean or replace more often in
dirty or dusty environments.
NOTE: If you need to order a new air filter, please call
1-800-336-PART.
Engine Governed Speed
CAUTION! The engine speed was properly adjusted
at the factory and should require no additional
adjustment. Do Not attempt to change engine speed. If
you believe the engine is running too fast or too slow,
take your unit to an authorized Sears service center for
repair and adjustment. CHANGING THE ENGINE
GOVERNED SPEED WILL VOID THE ENGINE
WARRANTY.
Do Not try to adjust the governed speed for the
following reasons:
• Operating the engine at high engine speeds is
dangerous and increases the risk of personal injury
or damage to the equipment.
• Operating the engine at low engine speeds with
heavy loads may shorten the engine's life.
Incorrect speed settings also affects electrical
operation of your generator as follows:
• Operating at high speeds results in an over-
frequency and over-voltage condition.
• Operating at low speeds causes an under-
frequency and under-voltage condition.
IMPORTANT: Incorrect frequency and/or voltage
may damage some connected electrical loads.
If you suspect engine speed is incorrect, take the
unit to an authorized Sears service facility for
repair and adjustment.
Carburetor Adjustments
The engine carburetor is preset at the factory. The
carburetor should not be tampered with because doing
so will void the emission control system warranty. If
you experience problems or your engine is used at an
altitude higher than 5,000 feet, contact the nearest
authorized Sears service center regarding high altitude
setting changes.
Cleaning Urethane Foam Element:
• Wash and clean the urethane foam in kerosene.
Saturate in a mixture of 3 parts kerosene and
1 part engine oil, and then squeeze to remove
excess oil. Clean or replace urethane foam
element every 50 hours (more often in dusty
conditions).
15
GENERAL
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 information as a
guide to prepare it for storage.
_ WARNING! Never store engine with fuel in
tank indoors or in enclosed, poorly ventilated
areas where fumes may reach an open flame,
spark or pilot light as on a furnace, water heater,
clothes dryer or other gas appliance.
LONG TERM STORAGE
It is important to prevent gum deposits from forming in
essential fuel system parts such as the carburetor, 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 gas 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, as
follows:
• Remove all gasoline from the fuel tank.
_ ARNING! Drain fuel into approved container
outdoors, away from open flame. Be sure
engine is cool. Do Not smoke.
• Start and run engine until engine stops from lack of
fuel.
• While engine is still warm, drain oil from crankcase.
Refill with recommended grade.
• Remove spark plugs and pour about 1/2 ounce
(15ml) of engine oil into each cylinder.
• Cover spark plug holes with rag. Crank the engine
for 2-3 seconds and reinstall the spark plugs.
Do Not connect spark plug wires.
• Remove the negative battery cable from the battery
to prevent the battery from being depleted.
WARNING! Fire, explosion and burn hazard!
The battery is water based. If you are storing the
generator in an area that will go below freezing,
you must remove the battery and store it
separately in an area that will not freeze. If you
allow the battery to freeze, the water in it will
expand and crack open the battery, spilling the
contents. Battery electrolyte fluid is an extremely
caustic sulfuric acid solution that can cause
severe burns. The spilled solution may also give
off hydrogen gas, which can ignite at the
slightest spark or flame and cause an explosion.
Clean the generator outer surfaces. Check that
cooling air slots and openings on generator are
open and unobstructed.
Store the unit in a clean, dry, frost-free area.
OTHER STORAGE TIPS:
• Do Not store gasoline from one season to another.
• Replace your gasoline can if the can starts to rust.
Rust and/or dirt in the gasoline will cause
problems.
• If possible, store your unit indoors and cover it to
give protection from dust and dirt. BE SURE TO
EMPTY THE FUEL TANK.
• Cover your unit with a suitable protective cover that
does not retain moisture.
_ AUTION! Never cover your generator while
engine and exhaust area are warm.
_ AUTION! Avoid spray from spark plug hole
when cranking engine.
