EXHAUST & LOCATION HAZARDS
• Never operate in an enclosed area or indoors! NEVER use in the
home, in a vehicle, or in partly enclosed areas such as garages,
even if doors and windows are open! ONLY use outdoors and far
from open windows, doors, vents, and in an area that will not
accumulate deadly exhaust.
• The engine exhaust fumes contain carbon monoxide, which you
cannot see or smell. This poisonous gas, if breathed in sufficient
concentrations, can cause unconsciousness or even death.
• Adequate, unobstructed flow of cooling and ventilating air is critical
to correct generator operation. Do not alter the installation or permit
even partial blockage of ventilation provisions, as this can seriously
affect safe operation of the generator. The generator MUST be operated
outdoors.
• This exhaust system must be properly maintained. Do nothing that
might render the exhaust system unsafe or in noncompliance with any
local codes and/or standards.
• Always use a battery operated carbon monoxide alarm indoors,
installed according to the manufacturers instructions.
• If you start to feel sick, dizzy, or weak after the generator has been
running, move to fresh air IMMEDIATELY. See a doctor, as you could
have carbon monoxide poisoning.
ELECTRICAL HAZARDS
• The generator produces dangerously high voltage when in operation.
Avoid contact with bare wires, terminals, connections, etc., while
the unit is running, even on equipment connected to the generator.
Ensure all appropriate covers, guards and barriers are in place before
operating 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 MAY RESULT.
• The National Electric Code (NEC) requires the frame and external
electrically conductive parts of the 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 the area.
• Use a ground fault circuit interrupter in any damp or highly conductive
area (such as metal decking or steel work).
• Do not use worn, bare, frayed or otherwise damaged electrical cord
sets with the generator.
• In case of accident caused by electric shock, immediately shut down
the source of electrical power. If this is not possible, attempt to free
the victim from the live conductor. AVOID DIRECT CONTACT WITH
THE VICTIM. Use a non-conducting implement, such as a rope
or board, to free the victim from the live conductor. If the victim is
unconscious, apply first aid and get immediate medical help.
FIRE HAZARDS
• Gasoline is highly FLAMMABLE and its vapors are EXPLOSIVE. Do
not permit smoking, open flames, sparks or heat in the vicinity
while handling gasoline.
• Never add fuel while unit is running or hot. Allow engine to cool
completely before adding fuel.
• Never fill fuel tank indoors. 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 over-filled, 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, spark or pilot light (as on
a furnace, water heater or clothes dryer). FIRE or EXPLOSION may
result. Allow unit to cool entirely before storage.
• Wipe up any fuel or oil spills immediately. Ensure that no combustible
materials are left on or near the generator. Keep the area surrounding
the generator clean and free from debris and keep a clearance of five
(5) feet on all side to allow for proper ventilation of the generator.
• Do not insert objects through unit’s cooling slots.
• Do not operate the generator if connected electrical devices overheat,
if electrical output is lost, if engine or generator sparks or if flames or
smoke are observed while unit is running.
• Keep a fire extinguisher near the generator at all times.

2.3.2 120 VAC, 20 AMP, GFCI RECEPTACLE
This unit is equipped with a ground fault circuit interrupter (GFCI). This
device meets applicable federal, state and local codes (Figure 10).
A GFCI receptacle is different from conventional receptacles. In the event
of a ground fault, a GFCI will trip and quickly stop the flow of electricity to
prevent serious injury.
Definition: Instead of following its normal safe path, electricity passes
through a persons body to reach the ground. For example, a defective
appliance can cause a ground fault.
A GFCI receptacle does NOT protect against circuit overloads, short
circuits, or shocks. For example, electric shock can still occur if a person
touches charged electrical wires while standing on a non-conducting
surface, such as a wood floor.
Figure 10 - 120 VAC, 20 Amp GFCI Receptacle

2.4 HOW TO USE THE GENERATOR
See the "To Start the Engine" section for how to safely start and stop
the generator and how to connect and disconnect loads. If there are any
problems operating the generator, please call the generator helpline at
1-888-436-3722.
Never operate in an enclosed area or indoors!
NEVER use in the home, in a vehicle, or in partly
enclosed areas such as garages, EVEN IF doors
and windows are open! ONLY use outdoors and
far from open windows, doors, vents, and in an
area that will not accumulate deadly exhaust.
The engine exhaust fumes contain carbon
monoxide, which can you cannot see or smell.
This poisonous gas, if breathed in sufficient
concentrations, can cause unconsciousness or
even death.
Adequate, unobstructed flow of cooling and
ventilating air is critical to correct generator
operation. Do not alter the installation or permit
even partial blockage of ventilation provisions,
as this can seriously affect safe operation of
the generator. The generator MUST be operated
outdoors.
This exhaust system must be properly
maintained. Do nothing that might render the
exhaust system unsafe or in noncompliance with
any local codes and/or standards.
Always use a battery operated carbon monoxide
alarm indoors, installed according to the
manufacturers instructions.
2.4.1 GROUNDING THE GENERATOR WHEN USED AS A
PORTABLE
This generator has an equipment ground that connects the generator
frame components to the ground terminals on the AC output receptacles
(see NEC 250.34 (A) for explanation). This allows the generator to be used
as a portable without grounding the frame of the generator as specified
in NEC 250.34.
Special Requirements
There may be Federal or State Occupational Safety and Health
Administration (OSHA) regulations, local codes, or ordinances that apply
to the intended use of the generator.
Please consult a qualified electrician, electrical inspector, or the local
agency having jurisdiction:
• In some areas, generators are required to be registered with local
utility companies.
• If the generator is used at a construction site, there may be
additional regulations which must be observed.
2.4.2 CONNECTING TO A BUILDING’S ELECTRICAL
SYSTEM
When connecting directly to a building's electrical system, it is
recommended that a manual transfer switch is used. Connections for
a portable generator to a building's electrical system must be made by
a qualified electrician and in strict compliance with all national and local
electrical codes and laws.
Operation

Figure 15 - Grounding the Generator
2.4.3 CONNECTING 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.
• Let engine stabilize and warm up for a few minutes after starting.
• Plug in and turn on the desired 120 or 240 Volt AC, single phase, 60
Hz electrical loads.
• 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"
below.
2.5 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 label 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
to allow for high starting wattage when selecting electrical devices to
connect to the generator:
1. Figure the watts needed to start the largest motor.
2. Add to that figure the running watts of all other connected loads.
The Wattage Reference Guide is provided to assist in determining how
many items the generator can operate at one time.
NOTE:
All figures are approximate. See data label on appliance for wattage
requirements.

2.7 BEFORE STARTING THE GENERATOR
Prior to operating the generator, engine oil and gasoline will need to be
added, as follows:
2.7.1 ADDING ENGINE OIL
All oil should meet minimum American Petroleum Institute (API) Service
Class SJ, SL or better. Use no special additives. Select the oil's viscosity
grade according to the expected operating temperature (also see chart).
• Above 40° F, use SAE 30
• Below 40° F and down to 10° F, use 10W-30
• Below 10° F, use synthetic 5W-30
Any attempt to crank or start the engine
before it has been properly serviced with the
recommended oil may result in an engine failure.
10W-30

1. Place generator on a level surface (not to exceed 15° in any
direction).
2. Clean area around oil fill and remove oil fill cap and dipstick. Dipstick
is accessible from the top of the unit next to the lifting eye in the
U-shape of the fuel tank.
3. Wipe dipstick clean; reinsert and remove dipstick and check oil level
against marks on dipstick.
4. If required, slowly fill engine with oil through the oil fill opening until
it reaches the full mark on the dipstick. Stop filling occasionally to
check oil level. Do not overfill.
5. Install oil fill cap and finger tighten securely.
6. Reinsert dipstick and seat firmly.
7. Check engine oil level before starting each time thereafter.
2.7.2 ADDING GASOLINE
Never fill fuel tank indoors. Never fill fuel tank
when engine is running or hot. Allow unit/engine
to cool entirely before adding fuel. DO NOT light a
cigarette or smoke when filling the fuel tank.
Do not overfill the fuel tank. Always leave room
for fuel expansion.
. To reduce lead and carbon deposits use high quality UNLEADED
gasoline with the generator engine. Leaded REGULAR grade
gasoline is an acceptable substitute. Do not use premium gasoline.
Do not mix oil with gasoline.
2. Clean area around fuel fill cap, remove cap.
3. Slowly add unleaded regular gasoline to fuel tank. Be careful not to
overfill. Allow about 1/2" of tank space for fuel expansion, as shown
in Figure 16.
4. Install fuel cap and wipe up any spilled gasoline.
Figure 16 - Fuel Tank
IMPORTANT: It is important to prevent gum deposits from forming in fuel
system parts such as the carburetor, fuel hose or tank during storage.
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 the "Storage" section. Never use engine or
carburetor cleaner products in the fuel tank as permanent damage may
occur.
The manufacturer does not recommend using any
gasoline containing alcohol (such as “gasohol”).
If using any gasoline containing alcohol, it must
not contain more than 10 percent ethanol, and
it must be removed from the generator during
storage. Do NOT use any gasoline containing
methanol. If using gasoline with alcohol,
inspect more frequently for fuel leaks and other
abnormalities.
2.8 TO START THE ENGINE
Never start or stop engine with electrical devices
plugged into the receptacles AND devices turned
on.
1. Unplug all electrical loads from the unit's receptacles before starting
the engine.
2. Make sure the unit is in a level position (not to exceed 15° in any
direction).
3. Open the fuel shut-off valve (Figure 17).
Operation
12
Figure 17 - Fuel Shut-off Valve
4. Locate the Idle Control ON/OFF switch on the control panel and set it
to the “OFF” position (Figure 18).
Figure 18 - Idle Control Switch
5. Move engine CHOKE knob outward to “Full Choke” position (Figure
19).
6. To start engine, press and hold the Start/Run/Stop switch in the
“Start” position. The engine will crank and attempt to start. When
the engine starts, release the switch to the run position.
7. When the engine starts, move choke knob to “1/2 Choke” position
until the engine runs smoothly and then fully in to the “Run” position.
If engine falters, move choke knob back out to “1/2 Choke” position
until the engine runs smoothly and then to “Run” position.
NOTE:
If engine fires, but does not continue to run, move choke lever to “Full
Choke” and repeat starting instructions.
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” carefully.
Figure 19 - Full Choke Position
2.9 STOPPING THE ENGINE
1. Shut off all loads, then unplug the electrical loads from generator
panel receptacles. Never start or stop the engine with electrical
devices plugged in and turned on.
2. Turn “Off” the Idle Control switch (if on).
3. Let engine run at no-load for several minutes to stabilize the internal
temperatures of engine and generator.
4. Move Start/Run/Stop switch to “Off” position.
5. Close fuel valve.
2.10 AUTOMATIC IDLE CONTROL
This feature is designed to greatly improve fuel economy. When this switch
is turned “On,” the engine will only run at its normal fast governed engine
speed when electrical load is connected. When the load is removed, the
engine will run at a reduced speed of 2100 RPM. With the switch “Off,”
the engine runs at the normal fast engine speed all the time. Always have
the switch OFF when starting and stopping the engine.
2.11 COLD WEATHER OPERATION/DE-ICER
Under certain weather conditions (temperatures below 40° F (4° C) and a
high dew point), the engine may experience icing of the carburetor and/or
the crankcase breather system. To eliminate this problem, this generator
engine is fitted with a winter/summer valve. This directs hot air into the
carburetor during cold weather operation. Always make sure the winter/
summer valve is in the correct location relative to the weather conditions.
2.12 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 10 psi. If the
engine shuts down by itself and the fuel tank has enough gasoline, check
engine oil level.
2.12.1 INITIAL START-UP
A delay built into 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.
Operation
13
2.12.2 SENSING LOW OIL PRESSURE
If the system senses low oil pressure during operation, the engine shuts
down.
2.12.3 RESTARTING
If trying to restart the engine within 10 seconds after it shuts down, the
engine may NOT start. The system needs five (5) to 10 seconds to reset.
If the engine is restarted after such a shutdown and the low oil pressure
has not been corrected, the engine will run for about 10 seconds as
described above and then stop.
2.13 CHARGING A BATTERY
Storage batteries give off explosive hydrogen
gas while recharging. An explosive mixture will
remain around the battery for a long time after
it has been charged. The slightest spark can
ignite the hydrogen and cause an explosion. Such
an explosion can shatter the battery and cause
blindness or other serious injury.
Do not permit smoking, open flame, sparks or
any other source of heat around a battery. 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. If spill
occurs flush area with clear water immediately.
This 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.
This battery charger is a pulse type designed to provide a quality charge
current into the battery. The voltage measured at the outlet should be 8-12
VDC. This is normal and does not indicate a faulty charging system.
To recharge 12 Volt batteries, proceed as follows:
1. Check fluid level in all battery cells. If necessary, add ONLY distilled
water to cover separators in battery cells. Do not use tap water.
2. If the battery is equipped with vent caps, make sure they are installed
and are tight.
3. If necessary, clean battery terminals.
4. Connect battery charge cable connector plug to panel receptacle
identified by the words "12-VOLT D.C."
5. Connect battery charge cable clamp with red handle to the positive
(+) battery terminal.
6. Connect battery charge cable clamp with black handle to the
negative (-) battery terminal.
7. Start engine. Let the engine run while battery recharges. Engine idle
control switch must be in off position for battery charging.
8. When battery has charged, shut down 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.
3.1 PERFORMING SCHEDULED

3.4 GENERAL RECOMMENDATIONS
The warranty of the generator 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 Maintenance section of this manual should be made
at least once each season. Follow the requirements in the "Maintenance
Schedule" chart.
NOTE:
Once a year, replace the spark plug and replace the air filter. A new
spark plug and clean air filter assure proper fuel-air mixture and help
the engine run better and last longer.
3.4.1 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.
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 crevices 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.
3.4.2 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.
3.4.3 ENGINE MAINTENANCE
When working on the generator, always disconnect
negative cable from battery. Also disconnect spark
plug wires from spark plugs and keep wire away
from spark plugs.
3.4.4 CHECKING OIL LEVEL
See the “BEFORE STARTING THE GENERATOR” section 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.
Hot oil may cause burns. Allow engine to cool
before draining oil. Avoid prolonged or repeated
skin exposure with used oil. Thoroughly wash
exposed areas with soap.
Maintenance
15
3.4.5 CHANGING THE OIL AND OIL FILTER
Change the oil and filter after the first 30 hours of operation. Change the
oil every 100 hours thereafter. If running this unit under dirty or dusty
conditions, or in extremely hot weather, change the oil more often.
Use the following instructions to change the oil after the engine cools
down:
1. Clean area around oil drain hose and plug.
2. Remove oil drain plug from end of hose and oil fill plug to drain oil
completely into a suitable container.
3. When oil has completely drained, install oil drain plug and tighten
securely.
4. Place a suitable container beneath the oil filter and turn filter
counterclockwise to remove. Discard according to local regulations.
5. Coat gasket of new filter with clean engine oil. Turn filter clockwise
until gasket contacts lightly with filter adapter. Then tighten an
additional 3/4 turn.
6. Fill oil sump with recommended oil. (See “Before Starting the
Generator” for oil recommendations).
7. Wipe up any spilled oil.
8. Dispose of used oil at a proper collection center.
3.4.6 REPLACING THE SPARK PLUGS
Use Champion RC14YC spark plug or equivalent. The correct air gap is
1.01 mm (0.040 in.). Replace the plugs every 200 hours. This will help
the engine start easier and run better.
1. Stop the engine and pull the spark plug wire off of the spark plug.
2. Clean the area around the spark plug and remove it from the cylinder
head.
3. Set the spark plug's gap to 1.01 mm (0.040 in.). Install the correctly
gapped spark plug into the cylinder head.
Figure 20 - Spark Plug Gap
3.5 SERVICE AIR CLEANER
The engine will not run properly and may be damaged if using a dirty
air cleaner. Clean or replace the air cleaner paper filter every 200 hours
or once a year. Clean or replace more often if operating under dusty
conditions. Clean foam pre-cleaner every month or more often under
dusty conditions.
To clean or replace paper air filter:
1. Remove air cleaner cover and remove paper filter.
2. Clean paper filter by tapping it gently on a solid surface. If the filter is
too dirty, replace it with a new one. Dispose of the old filter properly.
3. Clean air cleaner cover. Next insert new paper filter into the base of
the air cleaner. Re-install air cleaner cover.

3.6 CLEAN SPARK ARRESTOR SCREEN
The engine exhaust muffler has a spark arrestor screen. Inspect and clean
the screen at least once each year (Figure 22). If unit is used regularly,
inspect and clean more often.
NOTE:
If using the generator on any forest-covered, brush-covered or grass-
covered unimproved land, it must equipped with a spark arrestor. The
spark arrestor must be maintained in good condition by the owner/
operator.
Clean and inspect the spark arrestor as follows:
1. Remove the screen retaining bracket by removing the screw.
2. Slide the spark arrestor screen out from the tail pipe.
3. 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.
4. Replace the screen and the retaining bracket.

3.7 ADJUSTING VALVE CLEARANCE
After the first 50 hours of operation, check the valve clearance in the
engine and adjust if necessary.
Important: If feeling uncomfortable about doing this procedure or the
proper tools are not available, please take the generator to the nearest
service center to have the valve clearance adjusted. This is a very
important step to insure longest life for the engine.
To check valve clearance:
1. Make sure the engine is at room temperature (60° - 80° F).
2. Make sure that the spark plug wire is removed from the spark plug
and out of the way.
3. Remove the four screws attaching the valve cover.
4. Make sure the piston is at Top Dead Center (TDC) of its compression
stroke (both valves closed). To get the piston at TDC, remove the
intake screen at the front of the engine to gain access to the flywheel
nut. Use a large socket and socket wrench to rotate the nut and
hence the engine in a clockwise direction while watching the piston
through the spark plug hole. The piston should move up and down.
The piston is at TDC when it is up as high as it can go.
5. Insert a 0.002 - 0.004 inch (0.05 - 0.1mm) feeler gauge between the
rocker arm and valve stem. Correct clearance is when a slight drag is
felt when sliding the gauge back and forth. If the clearance is either
excessively loose or tight the rocker arms will need adjusting.
To adjust valve clearance:
1. Loosen the rocker jam nut (Figure 23). Use an 10mm 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 (0.05-0.1 mm).
NOTE:
The rocker arm jam nut must be held in place as the pivot ball stud is
turned.
Figure 23 - Valve Clearance Adjustment
When valve clearance is correct, hold the pivot ball stud in place with the
allen wrench and tighten the rocker arm jam nut. Tighten the jam nut to
174 in-lbs. torque. After tightening the jam nut, recheck valve clearance to
make sure it did not change.
2. Install new valve cover gasket.
3. Re-attach the valve cover.
NOTE:
Start all four screws before tightening or it will not be possible to get
all the screws in place. Make sure the valve cover gasket is in place.
4. Re-attach the spark plug wire to the spark plug.
5. Repeat the process for the other cylinder.
3.8 GENERAL
The generator should be started at least once every 30 days and be
allowed to run at least 30 minutes. If this cannot be done and the unit must
be stored for more than 30 days, use the following information as a guide
to prepare it for storage.
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.

3.9 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:
1. Remove all gasoline from the fuel tank.
Drain fuel into approved container outdoors, away
from open flame. Be sure engine is cool. Do not

3.10 OTHER STORAGE TIPS
• Do not store gasoline from one season to another.
• Replace the gasoline can if it starts to rust. Rust and/or dirt in the
gasoline will cause problems with the carburetor and fuel system.
• If possible, store the unit indoors and cover it to give protection from
dust and dirt. BE SURE TO EMPTY THE FUEL TANK.
• If it is not practical to empty the fuel tank and the unit is to be stored
for some time, use a commercially available fuel stabilizer added to the
gasoline to increase the life of the gasoline.
• Cover the unit with a suitable protective cover that does not retain
moisture.
NEVER cover the generator while engine and/or
