The engine exhaust from this product contains

chemicals known to the State of California

to cause cancer, birth defects, or other

reproductive harm.

CAUTION: Always disconnect spark plug wire
and place the wire where it cannot contact the
spark plug to prevent accidental starting when
setting up, transporting, adjusting or making
repairs to your generator.

DANGER: This generator is designed for
outdoor use only. Do Not use this generator
inside any building or enclosure, including the
generator compartment of a recreational
vehicle (RV). Fire or an explosion may result.
No user performed modifications, including
venting of exhaust and/or cooling ventilation,

will eliminate the danger. Allow at least two feet

of clearance on all sides of the generator while
operating the unit.

,_ CAUTION: Before using this product, read this

manual and follow all Safety Rules and
Operating Instructions.

• The generator produces dangerously high voltage
that can cause extremely hazardous electrical

shock. Avoid contact with bare wires, terminals,

etc. Never permit an unqualified person to operate
or service the generator.

• Never handle any kind of electrical cord or device
while standing in water, while barefoot or while

hands or feet are wet. Dangerous electrical shock

will result.

• The National Electric Code requires the frame and
external electrically conductive parts of generator

be properly connected to an approved earth

ground. Local electrical codes may also require

proper grounding of the generator. Consult with a
local electrician for grounding requirements in your

area.

• Do Not use worn, bare, frayed or otherwise
damaged electrical cord sets with the generator.

Using any defective cord set may result in

electrical shock or damage to equipment and/or

property.

• Operate generator only on level surfaces and
where it will not be exposed to excessive moisture,
dirt, dust or corrosive vapors.

• Never add fuel while unit is running.

• Allow at least 2 feet of clearance on all sides of
generator while operating unit or damage could

result. Read "Cold Weather Operation" on page 7.

• Gasoline is highly FLAMMABLE and its vapors are
EXPLOSIVE. Do Not permit smoking, open
flames, sparks or heat in the vicinity while handling
gasoline. Avoid spilling gasoline on a hot engine.
Comply with all laws regulating storage and
handling of gasoline.

• Do Not overfill the fuel tank. Always allow room for
fuel expansion. If tank is overfilled, fuel can
overflow onto a hot engine and cause FIRE or an

EXPLOSION.

• Never store generator with fuel in tank where
gasoline vapors might reach an open flame or
spark (as on a furnace, water heater or clothes
dryer). FIRE or an EXPLOSION might result.

• Generator exhaust gases contain DEADLY carbon
monoxide gas. This dangerous gas, if breathed in

sufficient concentrations, can cause
unconsciousness or even death. Operate this

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
wing nut is provided on the base of the cradle (note:
typical unit shown may not look like your unit).

Grounding Wing Nut

Generally, connecting a No. 12 AWG (American Wire

Gauge) stranded copper wire to the grounding wing

nut 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.

BEFORE STARTING THE

GENERATOR

To operate the engine you must do the following:

Add Engine Oil

NOTE: When adding oil to the engine crankcase in the

future, use only high quality detergent oil rated with
API service classification SF or SG or higher. Use no

special additives. Select the oil's viscosity grade

according to your expected operating temperature:

colder 32°F warmer

• Place unit on a level surface.

• Clean area around oil fill and remove oil dipstick.

• Wipe dipstick clean.

• Pour oil into oil fill opening until oil reaches FULL
mark on the dipstick. Do Not overfill!

Add Gasoline

,_ WARNING NEVER fill fuel tank indoors.

,_ CAUTION: Do Not overfill the fuel tank.

• Use regular UNLEADED gasoline with the

• Clean area around fuel fill cap, remove cap.

• Slowly add unleaded regular gasoline to fuel tank.

• Install fuel cap and wipe up any spilled gasoline.

IMPORTANT: 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 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. See "Storage" on
page 12. Never use engine or carburetor cleaner

products in the fuel tank or permanent damage may
occur.

NEVER fill fuel tank when engine is running or
hot. Do Not light a cigarette or smoke when

filling the fuel tank.

Always leave room for expansion.

• Let engine run at no-load for several minutes to

stabilize the internal temperatures of engine and
generator.

• Move Run/Stop switch to "Stop" position.

COLD WEATHER OPERATION

Under certain weather conditions (temperatures below
40°F [4°C] and a high dew point), your generator may
experience icing of the carburetor and/or the
crankcase breather system.

In an emergency, use the original shipping box as a

temporary shelter:

• Cut off all flaps.

• Cut out one of the long sides of the box to expose

exhaust side of unit. Ensure a minimum of two feet
clearance between open side of box and nearest

object.

• Cut appropriate slots to access receptacles and

clear handles.

• Start unit, then place box over it.

IMPORTANT!: Remove shelter when temperature is
above 40°F [4°C].

For a more permanent shelter, build a structure that
will enclose three sides and the top of the generator:

• Make sure entire muffler-side of generator is

exposed. Note that your generator may appear
different from that shown here.

• Grasp starter grip and pull slowly until you feel
some resistance. Then pull cord out with rapid full

arm stroke. Let rope return slowly. Do Not let rope
"snap back" against engine.

• When engine starts, move choke lever to "Half'
position until the engine runs smoothly and then to
"Run" position. If engine falters, move choke lever

to "Half" position until the engine runs smoothly

and then to "Run" position.

NOTE: If engine fails to start after 3 pulls, move the
choke lever to "Run" position and pull starter rope
again.

NOTE: If engine still fails to start after 3 pulls, check
for proper oil level in crankcase. This unit is equipped
with a Low Oil Shutdown System (see page 8).

NOTE: If engine fires but does not continue to run,

move choke lever to "Full" position and repeat starting

instructions.

TO STOP THE ENGINE

• Unplug all electrical loads from generator panel
receptacles. Never start or stop engine with
electrical devices plugged in AND turned on.

• Ensure a minimum of two feet clearance between
open side of box and nearest object.

• Face exposed end away from wind and elements.

• Enclosure should hold enough heat created by the
generator to prevent icing.

,_ CAUTION: NEVER run unit indoors; Do Not

enclose generator any more than shown.

Remove shelter when temperatures are above

40°F [4°C].

LOW OIL PRESSURE SHUTDOWN
SYSTEM

The engine is equipped with a low oil pressure sensor
that shuts down the engine automatically when the oil

pressure drops below 6 psi. If the engine shuts down
by itself and the fuel tank has enough gasoline, check

engine oil level.

Initial Start-up

A delay built in the low oil shutdown system allows oil

pressure to build during starting. The delay allows the

engine to run for about 10 seconds before sensing oil

pressure.

Sensing Low Pressure

If the system senses low oil pressure during operation,

the engine shuts down. As the system shuts down, the

low oil light comes ON. However, once the engine has

stopped rotating, this light will go OFF.

Restarting

If you try to restart the engine within 10 seconds after
it shuts down, the engine may NOT start. The system

needs 5 to 10 seconds to reset.
If you do restart the engine after such a shutdown and

have not corrected the low oil pressure, the engine

runs for about 10 seconds as described above and
then stops.

DON'T OVERLOAD THE
GENERATOR

Overloading a generator inexcess of its rated wattage
capacity can result in damage to the generator and to
connected electrical devices. Observe the following, to
prevent overloading the unit:

• Add up the total wattage of all electrical devices to
be connected at one time. This total should NOT

be greater than the generator's wattage capacity.

• The rated wattage of lights can be taken from light
bulbs. The rated wattage of tools, appliances and
motors can usually be found on a data plate or

decal affixed to the device.

• If the appliance, tool or motor does not give
wattage, multiply volts times ampere rating to
determine watts (volts x amps = watts).

• Some electric motors, such as induction types,
require about three times more watts of power for
starting than for running. This surge of power lasts
only a few seconds when starting such motors.
Make sure you allow for this high starting wattage
when selecting electrical devices to connect to your
generator. First, figure the watts needed to start the

largest motor. Add to that figure the running watts
of all other connected loads.

The Wattage Reference Guide below is provided to
assist you in determining how many items your

generator can operate at one time.

help your engine run better and last longer.

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

Equivalent

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.

CLEAN THE GENERATOR

Clean and inspect the spark arrestor as follows:

• To remove the muffler guard from the muffler,
remove the four screws that connect the guard to
the muffler bracket.

• Remove the four screws attaching the valve cover
with a #2 or #3 phillips screwdriver.

• Make sure the piston is at Top Dead Center (TDC)
of its compression stroke (both valves closed). To
get the piston to TDC, pull on the recoil handle
slowly while watching the piston through the spark
plug hole. As you pull on the recoil handle, the
piston should move up and down. The piston is at
TDC when it is up as high as it can go.

• Loosen the rocker arm jam nut. Use an 8 mm allen
wrench to turn the pivot ball stud while checking

clearance between the rocker arm and the valve
stem with a feeler gauge. Correct clearance is

0.002-0.004 inch (0.05-0.1mm). NOTE: You must
hold the rocker arm jam nut in place as you turn
the pivot ball stud.

• Inspect screen and replace if torn, perforated or
otherwise damaged. Do Not use a defective screen.

If screen is not damaged, clean it with commercial

solvent.

• Reattach the screen and the muffler guard.

Adjusting Valve Clearance

After the first 50 hours of operation, you should adjust
the valve clearance in the engine.

IMPORTANT: If you feel uncomfortable about doing

this procedure or you don't have the proper tools,

please take your generator in to the nearest Sears
service center to have the valve clearance adjusted.
This is a very important step to insure the longest life

for your engine.

To adjust valve clearance:

• Make sure the engine is at room temperature.

• Make sure that the spark plug wire is removed from

the spark plug and out of the way.

• Remove the breather tube from the valve cover.

O Loosen

Jam Nut

When valve clearance is correct, hold the pivot ball
stud in place with the allen wrench and tighten the
rocker arm jam nut to 65-85 inch-pounds torque.
After tightening the jam nut, recheck valve
clearance to make sure it did not change.

• Reattach the valve cover. Start all four screws
before tightening or you will not be able to get all

the screws in place. Make sure the gasket between
the valve cover and cylinder head is in place.

• Reattach the breather tube.

• Reattach the spark plug wire to the spark plug.

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.

Long Term Storage Instructions

Engine

Change Oil

While engine is still warm, drain oil from crankcase.
Refill with recommended grade.

Oil Cylinder Bore

_ ARNING: 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.

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 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. Follow

these instructions:

Generator

• Clean the generator as outlined on page 9 ("Clean
the Generator").

• Check that cooling air slots and openings on
generator are open and unobstructed.

Other Storage Tips:

• Do Not store gasoline from one season to another.

• Replace your gasoline can if it starts to rust.
Contaminated gasoline will cause engine 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.
