THE INFORMATION CONTAINED HEREIN WAS BASED ON
MACHINES IN PRODUCTION AT THE TIME OF PUBLICATION.
GENERAC RESERVES THE RIGHT TO MODIFY THIS MANUAL AT
ANY TIME.
SAFETY RULES
Throughout this publication, and on tags and decals affixed to the
generator, DANGER, WARNING, CAUTION and NOTE blocks are
used to alert personnel to special instructions about a particular
operation that may be hazardous if performed incorrectly or carelessly.
Observe them carefully. Their definitions are as follows:
Indicates a hazardous situation or action which, if
not avoided, will result in death or serious injury.
Indicates a hazardous situation or action which, if
not avoided, could result in death or serious injury.
Indicates a hazardous situation or action which,
if not avoided, could result in minor or moderate
injury.
NOTE:
Notes contain additional information important to a procedure
and will be found within the regular text body of this manual.
These safety warnings cannot eliminate the hazards that they
indicate. Common sense and strict compliance with the special
instructions while performing the action or service are essential to
preventing accidents.
Four commonly used safety symbols accompany the DANGER,
WARNING and CAUTION blocks. The type of information each
indicates is as follows:
This symbol points out important safety
information that, if not followed, could
endanger personal safety and/or property of
others.
This symbol points out potential explosion
hazard.
This symbol points out potential fire hazard.
This symbol points out potential electrical
shock hazard.
GENERAL HAZARDS
• NEVER operate in an enclosed area, in a vehicle, or indoors EVEN
IF doors and windows are open.
• For safety reasons, the manufacturer recommends that the
maintenance of this equipment is carried out by an Authorized
Dealer. Inspect the generator regularly, and contact the nearest
Authorized Dealer for parts needing repair or replacement.
• Operate generator only on level surfaces and where it will not be
exposed to excessive moisture, dirt, dust or corrosive vapors.
• Keep hands, feet, clothing, etc., away from drive belts, fans, and
other moving parts. Never remove any fan guard or shield while
the unit is operating.
• Certain parts of the generator get extremely hot during operation.
Keep clear of the generator until it has cooled to avoid severe
burns.
• Do NOT operate generator in the rain.
• Do not alter the construction of the generator or change controls
which might create an unsafe operating condition.
• Never start or stop the unit with electrical loads connected to
receptacles AND with connected devices turned ON. Start the
engine and let it stabilize before connecting electrical loads.
Disconnect all electrical loads before shutting down the generator.
Safety Rules
2
• When working on this equipment, remain alert at all times. Never
work on the equipment when physically or mentally fatigued.
• Never use the generator or any of its parts as a step. Stepping on
the unit can stress and break parts, and may result in dangerous
operating conditions from leaking exhaust gases, fuel leakage, oil
leakage, etc.
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 manufacturer's 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.
SAVE THESE INSTRUCTIONS – The manufacturer suggests that these rules for safe operation be copied and
posted near the unit's installation site. Safety should be stressed to all operators and potential operators of this
equipment.

PRE-USE CHECK
Prior to starting the generator and adding loads, perform the following
tasks:
1. Make sure the generator in on a firm, level, non-combustible
surface with at least five (5) feet of clearance on all sides.
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.
The manufacturer recommends installing
a battery operated carbon monoxide alarm
indoors, according to the manufacturer's
instructions.
NEVER use in the home, or in partly enclosed areas
such as garages, campers or trailers. ONLY use
outdoors and far from open windows, doors, vents.
2. Remove the fuel cap and check the fuel level. If fuel is needed,
see the section “FUELING THE GENERATOR”.
3. Remove the left side service cover and check the oil level by
removing the oil filler cap. The oil level should be to the bottom
of the threads on the oil fill pipe. If oil is needed, see the section
“ADDING ENGINE OIL”.
4. Replace and secure the left side service cover.
5. Make sure there are no loads connected to the generator.
6. The National Electric Code (NEC) requires the frame and
external electrically conductive parts of the generator be properly
connected to an approved earth ground. Proper grounding of the
generator will 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 unguarded devices.
7. Local electrical codes may also require proper grounding of the
generator.
Starting the generator with accessories
connected to the 120 VAC outlets will damage
the generator and the connected devices.
Operation
7
STARTING THE GENERATOR
Once the fuel and oil levels have been checked and it has been
verified there are no loads connected, the generator may be started.
Turn the FlexPower Switch OFF (O).
1. Open the fuel valve (Figure 4), located below the starter rope
pull, by turning to the valve 90° counter-clockwise to the “ON” (I)
position.
2. Locate the primer bulb (See Figure 5). Slowly, fully depress the
primer bulb and release. Allow the primer bulb to return to its
original state. Repeat this six (6) more times.
3. If the engine is cold or has not been run for some time, engage
the choke by pushing the choke lever to the right (Figure 6).
4. Grip the handle for the pull starter and brace your other hand
against the generator. Pull the rope slowly until resistance is felt,
then pull the rope rapidly up to three (3) times.
5. If the engine does not start, repeat steps 2-4 until the engine fires
and begins to run.

TURNING THE FUEL ON
6. Carefully adjust the choke to approximately the ½ position until
the engine begins to run smoothly, then push the lever all the way
to the left (Figure 6).
7. Make sure the bottom of the generator is not blocked by sand,
leaves, grass, etc. as the cooling vents are located on the bottom
of the unit.

Once the generator has been running smoothly for 2-3 minutes,
electrical loads can be added.
Do not use worn, bare, frayed or otherwise
damaged electrical cord sets with the
generator. Do not handle any kind of electrical
device while standing in water, while barefoot,
or while hands or feet are wet.
1. There are two grounded 120 VAC duplex outlets on the front of
the generator.
2. DO NOT overload the generator; if the red “overload” LED lights
up and the devices attached to the generator stop operating, stop
the engine and reduce the load to the generator. Restart and
apply reduced loads.
3. Consult the following table to estimate what can be powered by
the generator.

NOTE:
When an electric motor is started, the "OVERLOAD" LED may
light up for up to five (5) seconds (this is normal). If it stays on, a
fault has occurred. Remove all loads and shut down generator to
reset the alarm. Restart the generator. If the "OVERLOAD" LED
remains lit, contact a Generac Dealer for assistance.
USING THE FLEXPOWER™ SWITCH
When the accessories connected to the generator are going to be
used intermittently (such as a hand drill), the FlexPower™ switch
can be pushed to the “ON” (I) position. This will lower the generator
engine speed when loads are not being applied, saving fuel, reducing
engine wear and extending runtime.
USING THE 12 VDC BATTERY CHARGER
The 12 VDC receptacle may be used to recharge 12 VDC automotive
batteries only. The DC charging output is not regulated. The circuit
protector does not prevent over-charging a battery.
1. Connect the charging cable to the generator first, then the
battery, ALWAYS connecting the red lead to positive (+) and the
black to negative (-).
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 corrosive
sulfuric acid solution that can cause severe
burns. If a spill occurs, flush area with clear
water immediately.
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.
NEVER reverse the polarity when connecting
the battery terminals to the charging jack.
Severe damage may occur to the generator
and battery.
2. Keep the FlexPower™ switch in the “OFF” (O) position.
3. Start the generator and use it as normal. Charging time will vary
with battery size and condition. Check the voltage at the battery
terminals once the charging cable has been unplugged or the
generator has been shut down.
NOTE:
This receptacle can not recharge 6-Volt batteries and can not be
used to crank an engine having a discharged battery.
SHUTTING DOWN
Once the generator is no longer needed it can be shut down.
1. Switch off any devices connected to the generator. Unplug any
cords to the 120 VAC duplex outlets or the 12 VDC plug.
2. Turn the fuel valve to the “OFF” (O) position (Figure 7). A switch
behind the fuel valve grounds the ignition system, stopping the
engine and the fuel supply is shut off.
3. Close the vent on the fuel cap.
4. Allow the generator to cool before moving or storing.
Operation
9
Always allow the generator to cool off before
storing. High temperatures will be present
at the rear of the unit for some time after
shutdown.
Figure 7 - Turn Off Fuel
TURNING THE FUEL OFF
LOW OIL LEVEL SHUTDOWN
This generator is equipped with a low oil level shut down. If the oil
level in the engine crankcase drops below a pre-determined level,
the engine will stop automatically and the “LOW OIL LEVEL” LED
will light up.
Remove the Left Side Service Cover and check the oil level of
the engine. Add or drain oil as necessary; refer to see the section
“ADDING ENGINE OIL”.
FUELING THE GENERATOR
Use care when fueling the generator. Only fill the fuel tank when the
generator has cooled entirely. Use fresh unleaded gasoline with a
minimum Research Octane Number (RON) of 87.
NOTE:
Do not use any gasoline containing more than 10% Ethanol.
NEVER fill the fuel tank with E85 or a mixture of oil and gasoline
designated for two-cycle engines.
Do not light a cigarette or smoke when filling the
fuel tank.
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 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 allow
room for fuel expansion. If tank is over-filled,
fuel can overflow onto a hot engine and cause
FIRE or an EXPLOSION. Wipe up fuel spills
immediately!
TO FILL THE FUEL TANK
1. Remove the fuel tank cap.
Figure 8 - Fuel Tank Cap

FILL TANK UNTIL
FUEL IS TWO (2)
INCHES BELOW
THE TOP
2. Add fuel slowly, stopping about two (2) inches below the top of
the filler neck.
3. Replace the fuel tank cap. Make sure the valve on the fuel cap
is in the “OFF” position.
4. If the generator is going to be started, refer to the section
“STARTING THE GENERATOR” for additional directions on
priming the fuel system.
ADDING ENGINE OIL
All oil should meet minimum American Petroleum Institute (API)
Service Class SJ, SL or better. Do not use any aftermarket additives.
Select the oil's viscosity grade according to the expected operating
temperature, only a little more than one-half quart is needed.
• Above 40° F, use SAE 30
• Below 40° F to 10° F, use 10W-30
• Below 10° F, use synthetic 5W-30

2. Remove the Left Side Service Cover.
3. Remove the oil fill cap located on the bottom of the engine
crankcase.
4. Add the recommended engine oil slowly, stopping frequently to
check the level. The full level is the base of the threads in the filler
neck. DO NOT OVERFILL!
5. Replace the oil fill cap and tighten.
6. Always check the oil level before starting the generator engine.
DO NOT overfill the engine crankcase with
oil. High oil pressure may result, causing
premature engine wear and damage.

GENERATOR MAINTENANCE
Proper care will ensure maximum performance of your generator.
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:
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 the 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.

CLEANING THE GENERATOR
1. Use a damp cloth to wipe exterior surfaces clean.
2. A soft, bristle brush may be used to loosen caked on dirt, oil, etc.
3. A vacuum cleaner may be used to pick up loose dirt and debris.
4. 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.
5. Inspect the vent hoses on the left side of the generator. Make
sure the hoses protrude through the slots below the door and that
the ends are open and free of debris.
ENGINE MAINTENANCE
Only work on a generator that has cooled
completely.
Inspect the oil level and air filter condition each time you are going
to use the generator. To check the air filter and oil level the left side
service cover must be removed; use a screwdriver to loosen the
screw securing the cover and remove.
The air filter is located behind a cover for the air box (Figure 10). Push
the tab on the bottom of the air box upwards to release the cover. To
service the air cleaner:
1. Remove the air cleaner. Tap the element to shake loose any
large particles.
2. Wash the element in soapy water. Squeeze the filter dry in clean
cloth (DO NOT TWIST).
3. Soak the filter element in clean engine oil. Squeeze the excess
oil from the filter, leaving a light coating.
4. Clean air cleaner housing and cover before re-installing the filter
element.

CHANGING THE ENGINE OIL
Hot oil may cause burns. Allow engine to cool
entirely before draining oil. Avoid prolonged
or repeated skin exposure with used oil.
Thoroughly wash exposed areas with soap.
Change the engine oil after the first five (5) hours of operation. Change
the engine oil every 100 hours thereafter. To change the engine oil:
1. Run the generator briefly to warm the engine oil; this also loosens
any engine deposits and makes the used oil flow easier.
Change the oil only when the fuel tank is low
or nearly empty. Tipping the generator with a
full fuel tank may cause fuel leakage.
2. Place the generator over a drain pan and remove the drain
plug. Tip the generator on its side to drain the used oil from the
crankcase.
NOTE:
To make draining the oil easier, a 6” length of vinyl (PVC) hose
with an inside diameter of 1.25” (32mm) any be placed over the
drain lip.
3. Tip the generator upright once the oil has finished draining.
Replace the engine oil with the proper grade called out in Section
“ADDING ENGINE OIL”, then replace the drain plug.
CHANGING THE FUEL FILTER
Locate the fuel filter, just below the engine intake housing (Figure 11).
Make sure the Fuel Shutoff is in the “OFF” (O) position.
1. Remove the pinch clamps securing the fuel filter. Pull the hoses
free.
Wipe up any fuel spills immediately! Do not
smoke or replace the fuel filter near sparks or
open flame!
2. Replace the used filter with a new one. Push the fuel hoses onto
the barbed filter fittings until they are seated completely.
3. Replace the clamps, making sure they are seated on the fittings.

CHANGING THE SPARK PLUG
Replace the spark plug each year, regardless of how many hours the
generator has been run. Use a NGK BPR7HS that has be gapped to
.030” (.76mm). To replace the spark plug:
1. Remove the spark plug cover on the top right side of the
generator, just below the handle (Figure 12).
2. Carefully pull the spark plug lead from the spark plug. Use a
socket wrench to remove the spark plug.
3. Install the new spark plug into the cylinder head. Tighten the
spark plug to 15 ft/lb.
4. Replace the spark plug lead, making sure it is fully seated.
5. Replace the spark plug cover.
Figure 12 - Replace Spark Plug

LOCATION
TRANSPORTATION AND STORAGE
Transport or store the generator only if it has cooled completely. Make
sure the fuel valve and the vent on the fuel cap are both in the OFF
(“O”) position.
It is important to prevent gum deposits from forming in essential fuel
system parts such as the carburetor, fuel hose or tank during longterm storage. Also, experience indicates that alcohol-blended fuels
(called gasohol, ethanol or methanol) can attract moisture, which
leads to separation and formation of acids; these acids can damage
the fuel system of an engine while in storage.
To avoid engine problems, the use of a commercial fuel stabilizer prior
to storage is recommended. Follow the manufacturer’s instructions
when adding the fuel stabilizer.
If the generator is going to be stored for more than six (6) months, the
generator should be prepared as follows:
1. Remove all gasoline from the fuel tank.
2. Start and run engine until engine stops from lack of fuel or open the
valve on carburetor bowl (Figure 13), and allow gasoline to drain
down tube into a receptacle. Discard appropriately. Be sure to close
the valve once the gasoline has drained.

3. While engine is still warm, drain oil from crankcase. Refill with
recommended grade.
4. Remove spark plugs and pour about 1/2 ounce (15 ml) of engine
oil into the cylinders. Cover spark plug hole with rag. Pull the
starting rope several times to coat the cylinder walls with engine
oil.
5. Install and tighten the spark plug.
6. Clean the generator outer surfaces. Check that cooling air slots
and openings on generator are open and unobstructed.
7. Store the unit in a clean, dry place.
Do not store gasoline from one season to another.
If possible, store the unit indoors and cover it to give protection from
dust and dirt.

CLEAN SPARK ARRESTOR SCREEN (50 STATE)
The engine exhaust muffler has a spark arrestor screen. Inspect and
clean the screen every 50 hours of operation or once each year,
whichever comes first.
Clean and inspect the spark arrestor as follows:
• Remove the screen retainer by removing the retainer clamp.
• Slide the spark arrestor screen out from the muffler outlet tube.
• Inspect screen and replace if torn, perforated or otherwise
damaged. Do NOT use a defective screen. If screen is not
damaged, clean with a commercial solvent.
• Replace the screen and retainer and secure with retainer clamp.
