EVEN IF doors and windows are open.
• For safety reasons, the manufacturer recommends that the main-
tenance of this equipment is carried out by an Authorized Dealer.
Inspect the generator regularly, and contact the nearest Autho-
rized 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. Dis-
connect all electrical loads before shutting down the generator.
• Do not insert objects through unit’s cooling slots.
• 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.
1.2.2 — 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 criti-
cal 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.
• Thisexhaustsystemmustbeproperlymaintained.Donothingthat
mightrender the exhaustsystem unsafe orin noncompliance with
any local codes and/or standards.
• Always use a battery operated carbon monoxide alarm indoors,
installed according to the manufacturers instructions.
• Ifyoustarttofeelsick,dizzy, orweakafterthegenerator hasbeen
running, move to fresh air IMMEDIATELY. See a doctor, as you
could have carbon monoxide poisoning.
1.2.3 — Electrical Hazards
• The generator produces dangerously high voltage when in opera-
tion. 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. DANGER-
OUS ELECTRICAL SHOCK MAY RESULT.
• TheNationalElectricCode (NEC)requires the frame and external
electrically conductive parts of the generator be properly con-
nected 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 con-
ductive 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, discon-
nect theenginestartingbattery(ifequipped)toprevent accidental
start up. Disconnect the cable from the battery postindicated by a
NEGATIVE, NEG or (–) first. Reconnect that cable last.
• In case of accident caused by electric shock, immediately shut
downthe source ofelectricalpower.If thisisnotpossible,attempt
to free the victim from the live conductor. AVOID DIRECT CON-
TACT WITH THE VICTIM. Usea non-conductingimplement,such
asa rope orboard, to freethe victim fromthe live conductor. If the
victim is unconscious, apply first aid and get immediate medical
help.

1.2.4 — Fire Hazards
• LP gas is highly EXPLOSIVE.
• Flammable gas under pressure can cause a fire or explosion if
ignited.
• LP gas is heavier that air and can settle in low places while dissi-
pating.
• LP gas has a distinctive odor added to help detect potential leaks
quickly.
• In any propane gas fire, flames shouldnot beextinguishedunless
by doing so the fuel supply valve can be turned OFF.
• Ifthe fire is extinguished and a supplyoffuelisnotturnedOFF,an
explosion hazard greater than the fire hazard could be created.
• WhenexchangingLPcylinders,besurethecylindervalveisofthe
same type.
• Wipe up any fuel or oil spills immediately. Ensure that no combus-
tible materials are left on or nearthe generator. Keep the area sur-
rounding 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 over-
heat, 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.
NOTE:
This generator is equipped with a spark arrestor muffler. The
spark arrestor must be maintained in effective working order by
the owner/operator. In the state of California, a spark arrestor is
required by law (Section 4442 of the Public Resources Code).

2.4.3 — High Altitude Operation
At high altitude, the standard carburetor air-fuel mixture will be too
rich.Performance will decreaseand fuel consumption will increase. A
very rich mixture will also foul the spark plug and cause hard starting.
Operation at an altitude that differs from that at which this engine was
certified, for extended periods of time, may increase emissions.
High altitude performance can be improved by specific modifications
tothe carburetor.Ifyoualwaysoperate your engine at altitudes above
5,000feet(1,500 meters), have yourservicingdealer perform this car-
buretor modification. This engine, when operated at high altitude with
the carburetor modifications for high altitude use, willmeet each emis-
sion standard throughout its useful life.
See the table below to determine when an altitude kit is required..
NOTE:
Call 1-888-GENERAC to order an altitude kit if you are operating
the generator at 5000 - 7000 feet.

3.1 — 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 help-
line 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 you cannot see or smell. This poisonous gas, if
breathed in sufficient concentrations, can cause uncon-
sciousness 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 ventila-
tion provisions, as this can seriously affect safe opera-
tion 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.
3.1.1 — 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 recepta-
cles (see NEC 250.34 (A) for explanation). This allows the generator
tobe used asa portable withoutgrounding the frameof the generator
as specified in NEC 250.34.
3.1.1.1 — 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 addi-
tional regulations which must be observed.
3.1.2 — Connecting The Generator To A Building’s
Electrical System
When connecting directly to a building’s electrical system, it is recom-
mended that a manual transfer switch is used. Connections for a por-
table 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.
3.1.2.1 — Grounding The Generator In A Building
Standby Application
The National Electrical Code requires that the frame and
external electrically conductive parts of this generatorbe
properly connected to an approved earth ground.
Local electrical codes may also require proper grounding of the unit
(Figure 3-1). 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 ade-
quate protection against electrical shock. However, local codes may
vary widely. Consult with a local electrician for grounding require-
ments in the area.
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.

3.2 — Don’t Overload the Generator
Overloading a generator in excess of its rated wattage capacity can
resultin damage to the generator and to connectedelectrical devices.
Observe the following to prevent overloading the unit:
• Add up the total wattage of all electrical devices to be connected
atone time. This total should NOT be greater than thegenerator'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.
• Ifthe appliance, tool or motor doesnot give wattage, multiply volts
times ampere rating to determine watts (volts x amps = watts).
• Someelectricmotors,suchasinductiontypes,requireaboutthree
timesmore watts of powerforstarting than for running.Thissurge
of power lasts only a few seconds when starting such motors.
Make sure to allow for high starting wattage when selecting elec-
trical 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.

Operation
3.4 — Before Starting the Generator
Prior to operating the generator, engine oil and LP fuel will need to be
added, as follows:
3.4.1 — Adding Engine Oil
All oil should meet minimum American Petroleum Institute (API) Ser-
vice Class SJ, SL or better. Use no special additives. Select the oil's
viscositygradeaccordingtotheexpectedoperating 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
NOTE:
Synthetic oil should only be used after a 50 hour break-in period.
This is important to ensure proper cylinder wall and ring seating.
Any attempt to start the engine before it has been properly
serviced with the recommended oil may result in an engine
failure.
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.
3. Wipe dipstick clean.
4. Slowly fill engine with oil through the oil fill opening until it
reaches the full mark. Stop filling occasionally to check oil level.
Be careful not to over fill.
5. Install oil fill cap and finger tighten securely.
6. Check engine oil level before starting each time thereafter.
3.4.2 — Connecting LP Fuel Tank
Do not use or store LP cylinder in a building, garage or
enclosed area except as authorized by NFPA 58 or
B149.2 (in Canada).
Do not check for leaks with a match or flame.
The cylinder valve should be left off (closed) when the
generator is not in use.
NOTE:
LP vapor regulator inlet pressure is 30 psi at 0 °F, and 218 psi at
100 °F.
• Use only standard 20 or 30 pound capacity LP tanks with Type 1,
right hand Acme threads with this generator. Verify the re-qualifi-
cation date on the tankhas not expired. Do not use rustedor dam-
aged cylinders.
• All new cylinders must be purged of air and moisture prior to fill-
ing. Used cylinders that have not been plugged or kept closed
must also be purged.
• The purging process should be done by your propane gas sup-
plier. (Cylinders from an exchange supplier should have been
purged and filled properly already).
• Lift the tank and place carefully in the rear tank bracket with the
connection point facing the front of the generator (Figure 3-2).
• Insert the fixed end intothe side bracket with the smaller holeand
slide cotter pin in place. Firmly grasping the pivot end, stretch the
tankstraparoundthecylinder and slidethepeg intothekeyholein
the other bracket.
• Remove the safety plug or cap from the cylinder valve.
• Attach the connector snugly into the valve. Remember, turn the
plastic coupling from the hose right to tighten or clockwise.
• Always position the cylinder so the connection between the valve
and the regulator won’t cause sharp bends or kinks in the hose.
Figure 3-2: Position Tank
• Check for leaks by sprayingsoapy water tothe connections being
tested.
• If bubbles appear, become larger in size or increase in number, a
leak exists.
• This must be corrected before using the generator. Contact your
local Authorized Service Facility for assistance.
• Contactwithliquidcontents of the cylinder will causefreezeburns
to the skin.
• Do not allow children to tamper or play with the cylinder.

peratures.
** Clean more often under dirty ordusty operating conditions. Replace air filter parts if
they cannot be adequately cleaned.
*** Check valve clearance and adjust if necessary after first 50 hours of operation and
every 300 hours thereafter. This requires some engine disassembly. We recom-
mend contacting an Authorized Service Dealer for this adjustment.
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.
4.2 — 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 main-
tain 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”.
4.2.1 — Generator Maintenance
Generator maintenance consists of keeping the unit clean and dry.
Operate and store the unit in aclean dry environment where it will not
be exposed to excessive dust, dirt, moisture or any corrosive vapors.
Coolingairslotsinthegeneratormustnotbecomecloggedwithsnow,
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.
4.2.2 — 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.
• Lowpressure air (nottoexceed25psi)may be used to blowaway
dirt. Inspect cooling air slots and openings on the generator.
These openings must be kept clean and unobstructed.
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 wind-
ings will eventually decrease the insulation resistance of these
windings.
4.2.3 — Engine Maintenance
When working on the generator, always disconnect
sparkplug wirefrom spark plug and keepwire away from
spark plug.
4.2.4 — 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 leastevery eight hours of operation. Keep the oil level main-
tained.
4.2.5 — Changing The Oil
Change the oil after the first 30 hours and every 100 hours 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 after the engine
cools down:
1. Clean area around oil drain plug (Figure 4-1).
2. Remove oil drain plug from engine and oil fill plug to drain oil

4.3.1 — Clean Spark Arrestor Screen
The engine exhaust muffler has a spark arrestor screen. Inspect and
clean the screen at least once each year (Figure 4-6). If unit is used
regularly, inspect and clean more often.
If using the generator on any forest-covered, brush-cov-
ered 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 when the engine is at ambient
temperature as follows:
1. Remove the spark arrestor screen from the muffler by loosening
the clamp and removing the screw.
2. Inspect screen and replace if torn, perforated or otherwise dam-
aged. DO NOT USE a defective screen. If screen is not dam-
aged, clean it with commercial solvent.
3. Replace the spark arrestor and secure withthe clamp and screw.
