EXHAUST & LOCATION HAZARDS
Never operate in an enclosed area or indoors!
NEVER use in the home, 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.
Using a generator indoors CAN KILL
YOU IN MINUTES.
Generator exhaust contains carbon
monoxide. This is a poison you
cannot see or smell.
Si usa un generador en interiores,
MORIRÁ EN POCOS MINUTOS.
El escape del generador contiene
monóxido de carbono. Es un veneno
que no tiene olor ni se puede ver.
NEVER use inside a home or garage, EVEN IF doors and windows are open.
Only use OUTSIDE and far away from windows, doors, and vents.
NUNCA lo use dentro de una casa o garaje, AUN si las puertas y ventanas
están abiertas. Sólo úselo EN EXTERIORES y lejos de ventanas, puertas y
ductos de ventilación.
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.
The manufacturer recommends installing a battery operated• carbon monoxide alarm indoors, according to the manufacturers
instructions.
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.
Before performing any maintenance on the generator, disconnect•
the engine starting battery (if equipped) to prevent accidental
start up. Disconnect the cable from the battery post indicated
by a NEGATIVE, NEG or (–) first. Reconnect that cable last.
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.

2.4.1 SYSTEM GROUND
The generator has a system ground that connects the generator
frame components to the ground terminals on the AC output
receptacles. The system ground is bonded to the AC neutral wire
in the generator control panel via a jumper wire.
2.4.1.1 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.
2.4.1.2 Connecting to a Building’s Electrical System
Connections for standby power to a building’s electrical system
must be made by a qualified electrician. The connection must
isolate the generator power from utility power or other alternative
power sources and must comply with all related laws and codes.
2.4.2 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 (Figure 6).
Local electrical codes may also require proper grounding of the
unit. For that purpose, connecting a No. 10 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 the area.
Figure 6 - Grounding the Generator
CONNECT GENERATOR GROUND HERE
Proper grounding of the 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.
2.4.3 NEUTRAL TO FRAME GROUNDING
If service work is performed on the alternator, DO NOT discard
the white jumper wires from the terminal block to the alternator
ground, located on the rear bearing carrier. Alway make sure the
wires are properly connected before using the generator after
alternator service work is done (Figure 7).

2.4.4 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".
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.

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•
10W-30
10W-30
SAE 30
SAE 3 0
Synthetic 5W-30
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.
Place generator on a level surface.•
Clean area around oil fill and remove oil fill cap.•
Slowly fill engine with oil through the oil fill opening until it•
reaches the full mark. Stop filling occasionally to check oil
level. Engine oil is full when level is up to the threads of the oil
fill plug (Figure 8).
Install oil fill cap and finger tighten securely.•
Check engine oil level before starting each time thereafter.•
Figure 8 - Oil Level
2.7.2 ADDING GASOLINE
Never fill fuel tank indoors. Never fill fuel tank
when engine is running or hot. Avoid spilling
gasoline on a hot engine. Allow engine to cool
entirely before filling fuel tank.
Do not overfill the fuel tank. Always leave
room for fuel expansion. If the fuel tank is
overfilled, fuel can overflow onto a hot engine
and cause FIRE or EXPLOSION. Wipe up any
spilled fuel immediately.
Do not light a cigarette or smoke when filling
the fuel tank. Gasoline is highly FLAMMABLE
and its vapors are EXPLOSIVE.
Use the following instructions for adding gasoline:
Use regular UNLEADED gasoline with the generator engine. Do•
not mix oil with gasoline.
Do not use gasoline with more than 10% alcohol such as E85•
or Methanol.
Clean area around fuel fill cap, remove cap.•
Slowly add unleaded regular gasoline to fuel tank. Fill to bottom•
of screen filter. Be careful not to overfill (Figure 9).
Install fuel cap and wipe up any spilled gasoline.•
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.

2.8 TO START THE ENGINE
Never start or stop engine with electrical
devices plugged into the receptacles AND
devices turned on.
Unplug all electrical loads from the unit's receptacles before•
starting the engine.
Make sure the unit is in a level position.•
Open the fuel shut-off valve (Figure 10).•
Figure 10 – Fuel Shut-Off Valve
Slide engine CHOKE knob outward to• “Full Choke” position
(Figure 11).
NOTE:
The engine switch must be in the ON position.
To start manually, firmly grasp the recoil handle and pull slowly• until increased resistance is felt. Pull rapidly up and away to
start engine. Then follow the same choke sequence listed
above.
Figure 11 – Choke Operation
When the engine starts, slide choke knob to “1/2 Choke”• position until the engine runs smoothly and then fully in to the
“Run” position. If engine falters, slide 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, pull choke knob 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 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.
2.9 STOPPING THE ENGINE
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.
Let engine run at no-load for several minutes to stabilize the• internal temperatures of engine and generator.
MoveRun/Stop switch to “Off” position.•
Close fuel valve.•
2.10 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
5 psi. If the engine shuts down by itself and the fuel tank has
enough gasoline, check engine oil level.
2.10.1 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.
2.10.2 SENSING LOW OIL PRESSURE
If the system senses low oil pressure during operation, the engine
shuts down.
2.10.3 RESTARTING
If trying 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 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.

3.3 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".
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.
3.3.1 GENERATOR MAINTENANCE
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.
3.3.2 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.
3.3.3 ENGINE MAINTENANCE
When working on the generator, always
disconnect spark plug wire from spark plug
and keep the wire away from the spark plug.
3.3.4 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.
Section 3 — Maintenance
Portable Generator System

3.3.5 CHANGING THE OIL AND OIL FILTER
Change the oil and filter after the first 30 hours of operation. Change
the oil every 100 hours or every season thereafter. If running this
unit under dirty or dusty conditions, or in extremely hot weather,
change the oil more often.
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.
Use the following instructions to change the oil:
Clean area around oil drain plug.•
Remove oil drain plug from engine and oil fill plug to drain oil• completely into a suitable container.
When oil has completely drained, install oil drain plug and• tighten securely.
Place a suitable container beneath the oil filter and turn• filter counterclockwise to remove. Discard according to local
regulations.
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.
Fill engine with recommended oil. (See “Before Starting the• Generator” for oil recommendations).
Wipe up any spilled oil.•
Dispose of used oil at a proper collection center.•
3.3.6 REPLACING THE SPARK PLUG
Use Champion RC14YC spark plug or equivalent. Replace the
plug once each year. 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. To gain access, remove the four (4) screws and remove the
side panel.
3. Clean the area around the spark plug and remove it from the
cylinder head.
4. Set the spark plug's gap to .76 mm (0.030 in.). Install the
correctly gapped spark plug into the cylinder head (Figure
12).
5. Push the boot firmly on the spark plug and install side panel.
Figure 12 - Spark Plug Gap
3.4 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 (Figure 13). Clean or replace more often
if operating under dusty conditions.
To clean or replace paper air filter:
Remove air cleaner cover; then remove the paper filter.•
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.
Clean air cleaner cover, then insert new paper filter into the base•
of the air cleaner. Re-install air cleaner cover.

NOTE:
To order a new air filter, please contact the nearest authorized
service center at 1-888-436-3722.
3.5 CLEAN SPARK ARRESTOR SCREEN
The engine exhaust muffler has a spark arrestor screen. Inspect and
clean the screen every 100 hours or at least once each year (Figure
14). If unit is used regularly, inspect and clean more often.
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.
Section 3 — Maintenance
Portable Generator System

3.6 GENERAL
The generator should be started at least once every seven 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.
Allow unit to cool entirely before storage.
3.7 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.•
Drain fuel into approved container outdoors,
away from open flame. Be sure engine is cool.
Do not smoke in the vicinity or light a
cigarette.
Start and run engine until engine stops from lack of fuel•
Allow the engine to cool to the touch and then drain the oil from•
the crankcase. Refill with the recommended grade.
Remove spark plug and pour about 1/2 ounce (15 ml) of engine•
oil into the cylinder. Cover spark plug hole with rag. Pull the
recoil starter a couple times to lubricate the piston rings and
cylinder bore.
Avoid spray from the spark plug hole when
cranking engine.
Install and tighten the spark plug. Do not connect the spark plug•
wire.
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 place.•
3.8 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, in a garage or shed, 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
exhaust area are warm. Allow unit to cool
entirely.

Specifically, Generac makes no other warranties as to the merchantability or fitness for a particular purpose. Some states do not
allow limitations on how long an implied warranty lasts, so the above limitation may not apply to you.
The ECS Warranty applies only to the emission control system of your new equipment. If there is any conflict in terms between the
ECS Warranty and the Generac Warranty, the Generac Warranty shall apply. Both the ECS Warranty and the Generac Warranty
describe important rights and obligations with respect to your new engine.
Warranty service can be performed only by a Generac Authorized Warranty Service Facility. When requesting warranty service,
evidence must be presented showing the date of the sale to the original purchaser/owner.
If you have any questions regarding your warranty rights and responsibilities, you should contact Generac at the following

Section 6 – Warranty
Portable Generator System
EMISSION CONTROL SYSTEM WARRANTY
Emission Control System Warranty (ECS warranty) for equipment using small spark-ignited engines:
(a) Applicability: This warranty shall apply to equipment that uses small off-road engines. The ECS Warranty period shall begin
on the date the new equipment is purchased by/delivered to its original, end-use purchaser/owner and shall continue for 24
consecutive months thereafter.
(b) General Emissions Warranty Coverage: Generac warrants to the original, end-use purchaser/owner of the new engine or
equipment and to each subsequent purchaser/owner that the ECS when installed was:
(1) Designed, built and equipped so as to conform with all applicable regulations; and
(2) Free from defects in materials and workmanship which cause the failure of a warranted part at any time during the ECS
Warranty Period.
(c) The warranty on emissions-related parts will be interpreted as follows:
(1) Any warranted part that is not scheduled for replacement as required maintenance in the Owner's Manual shall be
warranted for the ECS Warranty Period. If any such part fails during the ECS Warranty Period, it shall be repaired or
replaced by Generac according to Subsection (4) below. Any such part repaired or replaced under the ECS Warranty shall
be warranted for the remainder of the ECS Warranty Period.
(2) Any warranted part that is scheduled only for regular inspection as specified in the Owner's Manual shall be warranted
for the ECS Warranty Period. A statement in the Owner’s Manual to the effect of "repair or replace as necessary" shall not
reduce the ECS Warranty Period. Any such part repaired or replaced under the ECS Warranty shall be warranted for the
remainder of the ECS Warranty Period.
(3) Any warranted part that is scheduled for replacement as required maintenance in the Owner's Manual shall be warranted
for the period of time prior to first scheduled replacement point for that part. If the part fails prior to the first scheduled
replacement, the part shall be repaired or replaced by Generac according to Subsection (4) below. Any such emissions-
related part repaired or replaced under the ECS warranty shall be warranted for the remainder of the period prior to the
first scheduled replacement point for that part.
(4) Repair or replacement of any warranted, emissions-related part under this ECS Warranty shall be performed at no charge
to the owner at a Generac Authorized Warranty Service Facility.
(5) Notwithstanding the provisions of subsection (4) above, warranty services or repairs must be provided at Generac
Authorized Service Facilities.
(6) When the engine is inspected by a Generac Authorized Warranty Service Facility, the purchaser/owner shall not be held
responsible for diagnostic costs if the repair is deemed warrantable.
(7) Throughout the ECS Warranty Period, Generac shall maintain a supply of warranted emission-related parts sufficient to
meet the expected demand for such parts.
(8) Any Generac authorized and approved emission-related replacement parts may be used in the performance of any ECS
warranty maintenance or repairs and will be provided without charge to the purchaser/owner. Such use shall not reduce
Generac ECS Warranty obligations.
(9) Unapproved, add-on, modified, counterfeit and/or "grey market" parts may not be used to modify or repair a Generac
engine. Such use voids this ECS Warranty and shall be sufficient grounds for disallowing an ECS Warranty claim. Generac
shall not be held liable hereunder for failures of any warranted parts of Generac equipment caused by the use of such an
unapproved, add-on, modified, counterfeit and/or "grey market" part.
EMISSION RELATED PARTS MAY INCLUDE THE FOLLOWING (IF EQUIPPED):
1) FUEL METERING SYSTEM
A. CARBURETOR AND INTERNAL PARTS
B. PRESSURE REGULATOR
2) AIR INDUCTION SYSTEM
