CARTON CONTENTS
Check all contents against those listed below:
• Main unit
• Oil bottle
• Owner's manual
• Battery charge cable
If any parts are missing or damaged, call the
generator helpline at 1-800-222-3136.
CONNECTOR PLUGS
120 Volt AC Receptacle
Each outlet socket is protected against overload by a
7.5 Amp push-to-reset circuit breaker. Use each
receptacle to operate 120 Volt AC, single phase,
60 Hz electrical loads requiring up to 1,000 watts
(1.0 kW) of power.
m/
mim m
_CAUTION! Although each receptacle is rated
for 120 Volts at 15 Amps (1,440 watts or
1.44 kW), the generator is rated for a total of
1,000 watts. Powering loads that exceed the
wattage capacity of the generator can damage it
or cause serious injuries. The total of loads
powered through these receptacles should not
exceed 7.5 Amps.
12 Volt DC Accessory Jack
This receptacle allows you to recharge a 12 Volt
automotive or utility style storage battery with the
battery charge cable provided. Camping-style air
pumps, lanterns, fans, or other 12 Volt devices having
a cigarette lighter-type plug may also be powered by
this outlet.
This receptacle can not recharge 6 Volt batteries and
can not be used to crank an engine having a
discharged battery. See the section "Charging a
Battery" (page 8) before attempting to recharge a
battery.
EXTENSION CORDS
Use only high quality, well-insulated, extension cords
with the generator's 120 Volt electrical receptacles.
Check the ratings of all extension cords before you
use them. Such cords should be rated for 125 Volt AC
loads at 15 Amps (or greater) for most electrical
devices. Some devices, however, may not require this
type of extension cord. Check the owner's manuals of
those devices for their recommendations.
Keep extension cords as short as possible, preferably
less than 15 feet long, to prevent voltage drop and
possible overheating of wires.

HOW TO USE YOUR GENERATOR
If you have any problems operating your generator
after reading the manual, 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 generator housing.
G
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 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 will need to 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 SG, SF/CC, CD. Select the
oil's viscosity grade according to your expected
operating temperature:
colder _ 32°F
SAE 10W30 SAE 30
SAE 10W-30 is recommended for general all
temperature use. Multi-viscosity oils (10W30, etc.)
improve starting in cold weather, but these oils will
result in increased oil consumption. Check your
engine oil level more frequently to avoid possible
damage from running low on oil.
To Add Engine Oil:
• Place the generator on a level surface.
• Remove the oil fill cover.
• Remove oil filler cap and wipe dipstick clean.

Engine exhaust contains carbon monoxide, an
odorless and deadly gas.
Connecting Electrical Loads
• Let the engine stabilize and warm up for a few
minutes after starting.
• 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.
• Plug in and turn on the desired 120 Volt AC, single
phase, 60 Hertz electrical loads.
• DO NOT OVERLOAD 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 the rated wattage/amperage capacity
of the generator. See "Don't Overload the
Generator" on page 9.
Stopping the Engine
• Unplug all electrical loads from the unit. Never start
or stop the engine with electrical devices plugged
in and turned on.
• Let the engine run at no-load for two minutes to
stabilize internal temperatures.
• Move the engine switch to the "OFF" position.
• Turn the fuel valve to the "CLOSE" position (fully
counterclockwise).
NOTE: In an emergency, stop the engine by moving
the engine switch to the "OFF" position.

Charging a Battery
WARNING! Storage batteries emit explosive
gas while charging that remains around a
battery for a long time after it has been charged.
The slightest spark can ignite the gas, causing
an explosion that can shatter the battery and
cause blindness or other injury.
_ARNING! Do Not permit smoking, open
flame, sparks or any other source of heat
around a battery. Do Not use a lighter or other
flame for checking battery fluid levels. Wear
protective goggles, rubber apron and rubber
gloves when working around a battery. Battery
electrolyte fluid is an extremely caustic sulfuric
acid solution that can cause severe burns.
Do Not permit fluid contact with eyes, skin,
clothing, etc. If spill occurs, flush area with clear
water immediately.
Your generator has the capability of recharging a
discharged 12 Volt automotive or utility style storage
battery. Do Not use the unit to charge any 6 Volt
batteries. Do Not use the unit to crank an engine
having a discharged battery.
To recharge 12 Volt batteries, proceed as follows:
•If necessary, clean battery posts or terminals.
• Check fluid level in all battery cells. If necessary,
add ONLY distilled water to cover separators in
battery cells. Do Not use tap water.
• If the battery is equipped with vent caps, make
sure they are installed and are tight.
• Connect battery charge cable connector plug to the
12 Volt DC panel receptacle.
• Connect battery charge cable clamp with red
handle to battery post or terminal indicated by
POSITIVE, POS or (+).

• Connect battery charge cable clamp with black
handle to battery post or terminal indicated by
NEGATIVE, NEG, or (-).
• Start generator. Let the engine run while battery
recharges.
• When battery has charged, shut down engine (see
"Stopping the Engine").
NOTE: Use an automotive hydrometer to test battery
state of charge and condition. Follow the hydrometer
manufacturer's instructions carefully. Generally, a
battery is considered to be at 100% state of charge
when specific gravity of its fluid (as measured by
hydrometer) is 1.260 or higher.

DON'T OVERLOAD THE
GENERATOR
Overloading a generator in excess 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 provided here may
assist you in determining appropriate generator load. It
is important to note that most of these devices require
more power than the generator can supply.

GENERAL RECOMMENDATIONS
The generator warranty does not cover items that
have been subjected to operator abuse or negligence.
To receive full value from the warranty, operator must
maintain generator as instructed in this manual.
Some adjustments will need to be made periodically to
properly maintain your generator.
All adjustments in this section should be made at least
once each season. Follow the requirements in the
"Maintenance Schedule" chart shown 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.
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.
10

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.
_AUTION! Never insert any object or tool
through the air cooling slots, even if the engine
is not running.
• 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.
,_ DANGER! When working on the generator
always disconnect spark plug wire from spark
plug and keep it away from spark plug.
ENGINE MAINTENANCE
Checking Oil Level
Oil level should be checked prior to each use or at
least every 5 hours of operation. Keep oil level
maintained.
Changing Engine Oil
Change the oil after the first month of operation, then
every 25 hours. If you are using your generator under
extremely dirty or dusty conditions, or in extremely hot
weather, change the oil more often.

• Check electrode gap with wire feeler gauge and set
spark plug gap between 0.028 and 0.031 inch
(0.7 to 0.8 mm) if necessary.
• Reinstall spark plug.
Service Air Cleaner
Your engine will not run properly and may be
damaged if you run it using a dirty air filter element.
Check the air filter every use and clean or replace the
paper air filter element every 50 hours of operation or
every three months, whichever comes first. Clean or
replace more often ifoperating under dusty or dirty
conditions.
To clean or replace air filter element:
• Loosen the air cleaner cover screws, remove the
air cleaner cover, and remove the element (see
item number 4, exploded view on page 20.
• Wipe clean the inside of the filter housing and

GENERAL
Transporting and Storage
When transporting the generator, turn the engine
switch to "OFF" and the fuel valve to "CLOSE". Keep
the generator level to prevent fuel spillage.
_ WARNING! Contact with a hot engine or
exhaust system can cause serious burns or
fires. Let the engine cool before transporting or
storing the generator.
Take care to not drop or strike the generator
when transporting. Do Not place heavy objects
on the generator.
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
_ 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.
Be sure the storage area is free from excessive
humidity and dust.
One Month to One Year
Drain the carburetor float bowl (see following section)
and fuel tank into a suitable container. After removal
from storage, fill with fresh gasoline before starting.
More than One Year
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.

• Remove spark plug and pour about one tablespoon
of clean engine oil into the cylinder.
,_ CAUTION! Avoid spray from spark plug hole
when cranking engine slowly.
• Cover spark plug hole with rag. Crank slowly
several times to distribute oil.
• Install spark plug. Do Not connect spark plug wire.
• Slowly pull the starter grip until resistance is felt. At
this point, the piston is coming up on its
compression stroke and both the intake and
exhaust valves are closed. Storing the engine in
this position will help to protect it from internal
corrosion.
Generator
• Clean the generator as outlined on page 11 ("To
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 the can starts to rust.
Rust and/or dirt in your 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.
• Store generator in clean, dry area.
IMPORTANT: Never cover your generator while
engine and exhaust area are warm.
