THE MANUFACTURER SUGGESTS THAT THESE “RULES” FOR SAFE OPERATION BE COPIED AND POSTED IN
POTENTIAL HAZARD AREAS OF THE RECREATIONAL VEHICLE. SAFETY SHOULD BE STRESSED TO ALL
OPERATORS AND POTENTIAL OPERATORS OF THIS EQUIPMENT.
• Inspect the generator periodically. Repair or replace all damaged or
defective parts immediately.
WARNING:
The engine exhaust from this product
contains chemicals known to the State
of California to cause cancer, birth
defects, or other reproductive harm.
In case of accident caused by electric shock, shut down the source
of electrical power at once. If this cannot be done, free victim from live
conductor. AVOID DIRECT CONTACT WITH THE VICTIM. Use a dry
board, dry rope, or other non-conducting implement to free the victim
from live conductor. If victim is unconscious, apply first aid and get
medical help
Study these SAFETY RULES carefully before installing, operating or servicing this equipment. Become familiar with the Owner’s Manual and with
the generator. The generator can operate safely, efficiently and reliably only
if it is properly installed, operated and maintained. Many accidents are
caused by failing to follow simple and fundamental rules or precautions.
• Inspect fuel system frequently for leaks or damage. Repair or replace
any damaged or leaking component immediately. Never attempt to
change, alter or modify the generator fuel system in any way that might
affect safety or compliance with applicable codes and standards.
Generac cannot possibly anticipate every possible circumstance that might
involve a hazard. The warnings in this Manual and on tags and decals affixed
to the unit, are therefore, not all-inclusive. If you use a procedure, work method
or operating technique Generac does not specifically recommend, you
must satisfy yourself that it is safe for you and others. You must also make
sure the procedure, work method or operating technique that you choose
does not render the generator to be unsafe.
The generator engine gives off DEADLY carbon monoxide gas through
its exhaust system. This dangerous gas, if breathed in sufficient concentrations, can cause unconsciousness or even death. This exhaust
system must have been properly installed, in strict compliance with
applicable codes and standards. Following installation, you must do
nothing that might render the system unsafe or in non-compliance with
such codes and standards. The generator compartment must be completely vapor sealed from vehicle interior. There must be no possibility
of exhaust fumes entering the vehicle interior. Never operate this
equipment with a leaking or defective exhaust system.
• For fire safety, the auxiliary generator must be installed and maintained
properly. Installation must always comply with applicable codes, standards,
laws and regulations. Adhere strictly to local, state and national electrical and building codes. Comply with regulations the Occupational Safety
and Health Administration (OSHA) established. Also, the generator and
related components must be installed completely in conformance with
the manufacturer’s instructions and recommendations. Following proper
installation, do nothing that might alter a safe installation and render the
unit in non-compliance with such codes, standards, laws and regulations.
• 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.
The Recreational Vehicle Generator produces extremely high and
dangerous electrical voltages and can cause dangerous, and possibly fatal, electrical shock. Avoid contact with bare wires, terminals, etc.
while the unit is running. If you must work around an operating generator, stand on an insulated, dry surface to reduce shock hazard.
Never work on this equipment or handle any electrical device while
standing in water, while barefoot, or while hands or feet are wet. Dangerous electrical shock will result.
• Do not smoke around the generator. Wipe up any fuel or oil spills immediately. Never leave oily or fuel soaked rags in the generator compartment
or on the generator itself. Keep the area around the generator clean and
free of debris.
• Adequate ventilation is required to expel toxic fumes and fuel vapors from
the generator compartment. Do not alter the installation of this equipment in any manner that might obstruct air and ventilation openings. Such
openings must be kept clear and unobstructed.
• Have the generator properly grounded (bonded) during installation onto
the vehicle, either by solid mounting to the vehicle frame or chassis or
by means of an approved bonding conductor. DO NOT disconnect the
bonding conductor, if so equipped. DO NOT reconnect the bonding conductor to any generator part that might be removed or disassembled during
routine maintenance. If the grounding conductor must be replaced, use
only a flexible conductor that is of No. 8 AWG copper wire minimum.
Some generators may use LP gas (propane) as a fuel. LP gas is highly
EXPLOSIVE. The gas is heavier than air and tends to settle in low
areas where even the slightest spark can ignite the gas and cause an
explosion.
• Before performing any maintenance on the generator set, disconnect its
battery cables to prevent accidental start up. Disconnect the cable from
the battery post indicated by a NEGATIVE, NEG or (–) first. Reconnect
that cable last.
• Keep hands, feet, clothing, etc., away from drive belts, fans and other
moving parts of this equipment. Never remove any drive belt or fan
guards while the unit is operating.

GENERATOR APPLICABILITY
Owners/Operators must make sure to do nothing that might
render the installation unsafe or in noncompliance with applicable codes, standards and instructions. They should be sure
the unit has been installed to allow adequate ventilation for cooling and exhaust air.
These generators have been designed and manufactured for
supplying electrical power for recreational vehicles. You should
not modify the generator or use it for any application other than
for what it was designed. If there are any questions pertaining to its application, write or call the factory. Do not use the
unit until you have been advised by a competent authority.
SAFETY
Before attempting to use the generator set, carefully read
GENERAL SAFETY RULES inside the cover of this Manual.
Comply strictly with these RULES to prevent accidents and
damage to equipment and/or property. We suggest that copying and posting GENERAL SAFETY RULES in potential hazard
areas of the vehicle. Stress safety to all operators and potential operators of this equipment.
DANGER: FOR FIRE SAFETY, THE GENERATOR
MUST HAVE BEEN PROPERLY INSTALLED IN
COMPLIANCE WITH (1) ANSI 119.2-1975/NFPA
501C-1974 “STANDARD FOR RECREATIONAL
VEHICLES, PART III, “INSTALLATION OF ELECTRICAL SYSTEMS.” THE GENERATOR ALSO MUST
HAVE BEEN INSTALLED IN STRICT COMPLIANCE
WITH THE MANUFACTURER’S DETAILED INSTALLATION INSTRUCTIONS. AFTER INSTALLATION,
DO NOTHING THAT MIGHT RENDER THE UNIT IN
NON-COMPLIANCE WITH SUCH CODES, STANDARDS AND INSTRUCTIONS.
GENERATOR AC CONNECTION
SYSTEM
This generator set is equipped with dual stator AC power
windings. These two stator windings supply electrical power
to customer electrical loads by means of a dual 2-wire connection system. Note, however, that neutral is grounded.
You can use this generator to supply electrical power for operating 120/240 volts, single phase, 60 Hertz, AC electrical
loads. These loads can require up to 4500 watts of (4.5kW)
of power, but cannot exceed 37.5 AC amperes of current at
120 volts or exceed 18.8 AC amperes at 240 volts.
The generator may have been installed so that the unit powers
120 volt AC loads (Figure 1); or you can wire them to connect
both 120 and/or 240 volt AC electrical loads. Be sure to install
jumper wire between the circuit breakers when reconnecting
for 120/240 volts. Refer to the Installation Manual for more
information.
CAUTION: Do not overload the generator. Some
installations may require that electrical loads be
alternated to avoid overloading. Applying excessively high electrical loads may damage the
generator and may shorten its life. Add up the
rated watts of all electrical lighting, appliance, tool
and motor loads the generator will power at one
time. This total should not be greater than the
wattage capacity of the generator. If an electrical
device nameplate gives only volts and amps, multiply volts times amps to obtain watts (volts x amps
= watts). Some electric motors require more watts
of power (or amps of current) for starting than for
continuous operation.
Figure 1 — Connections for 120 Volts Only
INSTALLATION
This Owner’s Manual has been prepared under the assumption that a competent, qualified technician installed the
generator. We also assume the installer complied with all
applicable codes, standards and regulations pertaining to
installation.

DANGER: The generator engine gives off DEADLY
carbon monoxide gas through its exhaust system.
This dangerous gas, if breathed in sufficient concentrations, can cause unconsciousness or even
death. DO NOT OPERATE THE GENERATOR IF
THE EXHAUST SYSTEM IS LEAKING OR HAS
BEEN DAMAGED. SYMPTOMS OF CARBON
MONOXIDE POISONING ARE (a) inability to think
coherently; (b) vomiting; (c) twitching muscles; (d)
throbbing temples; (e) dizziness; (f) headaches;
(g) weakness and sleepiness. IF YOU FEEL ANY
OF THESE SYMPTOMS, MOVE INTO FRESH AIR
IMMEDIATELY. IF SYMPTOMS PERSIST, GET MEDICAL HELP.
BEFORE STARTING THE ENGINE
IMPORTANT: INSTRUCTIONS AND INFORMATION IN THIS
MANUAL ASSUME THE GENERATOR HAS BEEN PROPERLY INSTALLED, CONNECTED, SERVICED, TESTED AND
ADJUSTED BY A QUALIFIED INSTALLATION TECHNICIAN
OR INSTALLATION CONTRACTOR.
INSTALLATION
Generator installation must have been properly completed so
it complies with all applicable codes, standards and regulations and with the manufacturer's recommendations.
ENGINE LUBRICATION
Have engine crankcase properly serviced with recommended
oil before starting. Refer to MAINTENANCE and SPECIFICATIONS sections for oil servicing procedures and
recommendations.
STARTING THE GENERATOR
IMPORTANT: Read the vehicle manufacturer’s instructions.
The owner/operator should become familiar with the vehicle
in which the generator is installed. Differences exist between
vehicles. For example, some vehicles may use a transfer
switch to isolate dockside power from the generator, while other
vehicles may use an isolating receptacle. Some vehicles may
be equipped with a DC converter which allows the generator
to power certain DC lighting and other DC loads.
CAUTION: Any attempt to crank or start the engine
before you have properly serviced it with the recommended oil may result in an engine failure.
FUEL SUPPLY
The engine must have adequate supply of proper fuel to operate. Before starting, check that sufficient fuel is available.
To start the generator from either the generator control panel
or from the optional Remote Panel, proceed as follows:
COOLING AND VENTILATING AIR
1. Turn OFF electrical loads, using whatever means provided
in your vehicle (such as a main line circuit breaker or transfer switch).
Air inlet and outlet openings in generator compartment must
be open and unobstructed for continued proper operation.
Without sufficient cooling and ventilating air flow, the enginegenerator quickly overheats which causes it to shutdown and
it could damage the generator.
NOTE: If starting from the generator panel, turn OFF loads
by setting the generator’s main circuit breaker to “OFF” or
“OPEN”. If starting from a Remote Panel, turn OFF loads using
whatever means is provided in the vehicle (such as a main circuit breaker). Electrical load circuits will be turned ON after
the generator has started, stabilized and warmed up.
ENGINE EXHAUST GAS
Before starting the generator engine, you should be sure there
is no way for exhaust gases to enter the vehicle interior and
endanger people or animals. Close windows, doors and other
openings in the vehicle that, if open, might permit exhaust gases
to enter the vehicle.
2. If you have not started the engine in more than two weeks,
press the Fuel Primer switch and hold it for about 30 seconds
to prime fuel system. However, if the engine is warm, skip Step
2.

3. Hold the engine Start/Stop Switch at START to crank engine.
Release the switch when the engine starts.
LET ENGINE STABILIZE
The generator supplies correct rated voltage only at proper
governed speed. Some electrical appliances may be extremely
sensitive to voltage. Incorrect voltages can damage those
appliances.
If electrical loads are applied at reduced operating speeds,
such loads imposed on the engine when sufficient power is not
available may shorten engine life. Never turn ON electrical
loads until after the generator engine has started and stabilized ON-speed.
CAUTION: If the engine does not start after it has
been cranking for 15 seconds, release the
start/stop switch and try again. Holding the switch
for longer than 15 seconds can damage the starter
motor.
4. Let the engine run at no-load for a few minutes to stabilize
and warm up.
5. Turn ON electrical loads, using whatever means provided
(such as a main circuit breaker or transfer switch).
DO NOT OVERLOAD THE GENERATOR
You can read the rated wattage/amperage capacity of your generator on the generator data decal (see “Identification Record”
on Page 3).
STOPPING THE GENERATOR
1. Turn OFF all electrical loads, using whatever means provided (such as a main circuit breaker or transfer switch).
Applying electrical loads in excess of the unit’s rated capacity will cause the engine-generator to automatically shutdown.
2. Let unit run a few minutes to stabilize temperature.
3. Hold the Start/Stop switch in its STOP position until engine
comes to a complete stop.
To avoid overloading, add up the wattage of all connected electrical lighting, appliance, tool and motor loads. This total should
not be greater than the generator’s rated wattage capacity.
APPLYING LOADS TO GENERATOR
Most lighting, appliance, tool, and motor loads indicate their
required watts on their nameplate or data plate. For light
bulbs, simply note the wattage rating of the bulb.
If a load does not show its rated wattage, multiply that load’s
rated VOLTS times AMPS to obtain WATTS.
When applying electrical loads to the generator, observe these
guidelines:
Before applying electrical loads, let the generator stabilize
and warm up for a minute or two.
DO NOT overload the generator.

Generac NP-50LPG Recreational Vehicle Generator
Induction type motors (such as those that run the vehicle’s
furnace fan, refrigerator, air conditioner, etc.) need about 21/2 time more watts of power for starting than for running
(for a few seconds during motor starting). Be sure to allow
for this when connecting electrical loads to the generator.
First, figure the watts needed to start electric motors in the
system. To that figure, add the running wattages of other
items that will be operated by the generator.
Do not apply heavy electrical loads for the first two or three
hours of operation.
FIELD BOOST
The Controller Circuit Board houses a field boost diode and
resistor which are part of a “field boost” circuit (Figure 5).
During engine cranking only, a positive DC (battery) voltage
is delivered through the diode, resistor, brushes and slip rings,
and the generator rotor. Application of this voltage to the
rotor “flashes the field” whenever it is started. Flashing of the
field each time the generator starts makes sure that a sufficiently strong magnetic field is available to produce “pick-up”
voltage in the stator windings.
ADDITIONAL INFORMATION
This section discusses some the the engine protective devices,
overload protection and breaking in a new generator.
Figure 5 — Field Boost Circuit
AUTOMATIC LOW OIL PRESSURE
SHUTDOWN
The engine is equipped with a normally-closed (N.C.) oil pressure switch (Figure 4). Engine oil pressure holds the switch
open during cranking and operation. Should oil pressure drop
below a pre-set level, the switch contacts close and the engine
automatically shuts down.
HIGH TEMPERATURE SHUTDOWN
A temperature switch (Figure 4) with normally-open (N.O.) contacts is mounted near the oil filter. If engine temperature were
to exceed about 284°F (140°C), the switch contacts close
and the engine shuts down.
OVERVOLTAGE PROTECTION
A solid state voltage regulator (Figure 6) controls the generator’s AC output voltage. This regulator supplies an excitation
current to the rotor. By regulating the rotor’s excitation current, the strength of its magnetic field is regulated and, in
turn, the voltage delivered to connected electrical loads is
controlled. When the AC frequency is 60 Hz, voltage is regulated at 120 volts (voltage-to-frequency ratio is 2-to-1).

Generac NP-50LPG Recreational Vehicle Generator
The voltage regulator also incorporates a “voltage surge protection circuit.” This circuit prevents troublesome surges in the
generator AC output voltage. Voltage surge is a common cause
of damage to electronic equipment.
ATTENTION REQUIRED AFTER SUBMERSION
If the recreational vehicle generator has been submerged in
water, it must NOT be started or operated. Following any submersion in water, have an authorized Generac Service Facility
thoroughly clean and dry the generator.
25-HOUR BREAK IN PERIOD
The first 25 hours of operation is the break-in period for the
generator. Properly breaking in the generator is essential to
minimize fuel consumption and provide maximum engine performance. During this 25-hour break in period, follow this
procedure:
OPERATING PRECAUTIONS
Never operate the generator set while the vehicle is parked
over dry leaves, dry grass or any other combustible substance.
The generator’s exhaust system becomes extremely hot and
can cause fire if it is too close to combustible materials.
The generator’s exhaust system gives off DEADLY carbon
monoxide gas. this dangerous gas, if breathed in sufficient
concentrations, can cause unconsciousness and even death.
never operate the generator set with the vehicle inside any
garage or enclosed area. Never operate the generator if it has
a leaky exhaust system. Close windows in the vicinity of the
generator exhaust outlet and take any other steps to prevent
exhaust gases from entering rooms or areas occupied by
people or animals.
• Run the unit at varying electrical loads, to help seat engine
piston rings properly.
• For the 75-hour operation following the break in period,
avoid light electrical loads. Load the generator at 50% (or
more) of its rated wattage capacity. Repeated light loads
during these 75 hours can cause improper seating of engine
piston rings, resulting in blowby and high oil consumption.
• Check engine oil level frequently. Add oil if needed. It is
normal for the generator engine to consume more oil than
is normal until the piston rings have properly seated.
• After operating the unit for 25 hours, complete the tasks recommended under “25-Hour Check Up.”
EFFECTS OF MOISTURE AND DIRT
Keep the generator set as clean and dry as possible. Protect
the unit against excessive dust, dirt, corrosive vapors, road
splash, etc. Permitting dirt and moisture to accumulate on
generator windings will have an adverse effect on the insulation resistance of those windings.
When moisture is allowed to remain in contact with windings,
some of the moisture will be retained in voids and cracks in the
insulation. This causes a reduced insulation resistance and
will eventually cause problems. Dirt will make the problem
worse, since dirt tends to hold moisture in contact with windings. Salt (as from sea air) will also worsen the problem since
it tends to absorb moisture from the air. Salt and moisture,
when combined, form a good electrical conductor.
25-HOUR CHECK UP
After the 25-hour break-in period, contact an authorized service facility for the following maintenance. The vehicle owner
is responsible for any charges:
• Change engine crankcase oil and oil filter.
Check oil level.
• Inspect cooling and ventilation openings.
Check engine carburetor.
• Check engine ignition system.
• Inspect entire electrical system.
• Inspect the engine exhaust system.
OPERATION IN HIGH GRASS
OR BRUSH
WARNING: NEVER OPERATE THE GENERATOR
WHILE THE VEHICLE IS PARKED IN HIGH GRASS,
WEEDS, BRUSH OR LEAVES. SUCH MATERIALS
CAN IGNITE AND BURN FROM THE HEAT OF THE
EXHAUST SYSTEM. THE GENERATOR EXHAUST
BECOMES EXTREMELY HOT DURING OPERATION
AND REMAINS HOT FOR A LONG TIME AFTER IT
HAS SHUT DOWN.

“NP” series generators require a “vapor withdrawal” type fuel
system. This type of gaseous fuel system uses the vapors
forming above the liquid fuel in the storage tank. Air temperature around the storage tank must be high enough to sustain
adequate fuel vaporization. In colder climates, you may need
to use an independent heat source to be sure the fuel sufficiently vaporizes in the storage tank.
LP gas may consist of propane, butane or a mixture of two
gases. Using fresh HD-5 LP is recommended. Fuel should
not contain more than 2.5% butane. Propane vaporizes at temperatures as low as -20°F (-29°C), but butane returns to its
liquid state when the temperature drops below about 32°F
(0°C). For that reason, a higher ratio of propane is desired in
the gas mixture when temperatures drop below freezing.

SPARK ARRESTOR MUFFLER
BATTERY
If the generator is not equipped with a spark arrestor exhaust
muffler and is to be used on any forest covered, brush covered or grass covered unimproved land, you may have to
install a spark arrestor. The spark arrestor must be maintained
in effective working order by the vehicle owner/operator.
All lead-acid storage batteries will discharge when not in use.
The generator battery should be inspected as follows:
ONCE WEEKLY
Inspect battery posts and cables for tightness, corrosion.
Clean and/or tighten as needed.
For assistance in ordering, installing and maintaining spark
arrestor exhaust mufflers, contact your nearest authorized
service facility.
Also check battery fluid level, and, if necessary, fill with DISTILLED WATER ONLY. DO NOT USE TAP WATER IN
BATTERY.
Exhaust mufflers supplied by Generac are spark arrestor
types. Generac exhaust muffler for recreational vehicle generators do not have a spark arrestor screen, but are of the more
efficient “toroid” or “swirl” type. To remove carbon and combustion deposits from such mufflers, remove the PLUG from
the muffler and run engine for about 15 minutes. Shut engine
down, let the muffler cool and install the plug.
EVERY SIX MONTHS
Have battery state of charge and condition checked. This
should be done with an automotive type battery hydrometer.
DANGER: STORAGE BATTERIES GIVE OFF
EXPLOSIVE HYDROGEN GAS. THIS GAS CAN
FORM AN EXPLOSIVE MIXTURE AROUND THE
BATTERY FOR SEVERAL HOURS AFTER CHARGING. THE SLIGHTEST SPARK CAN IGNITE THE
GAS AND CAUSE AN EXPLOSION. SUCH AN
EXPLOSION CAN SHATTER THE BATTERY AND
CAUSE BLINDNESS OR OTHER INJURY. ANY
AREA THAT HOUSES A STORAGE BATTERY MUST
BE PROPERLY VENTILATED DO NOT ALLOW
SMOKING, OPEN FLAME, SPARKS OR ANY
SPARK PRODUCING TOOLS OR EQUIPMENT
NEAR THE BATTERY.
WARNING: BE SURE TO RE-INSTALL THE PLUG
FROM THE MUFFLER TIGHTLY. ENGINE VIBRATION
COULD CAUSE A LOOSE PLUG TO FALL OUT.
WITHOUT THE PLUG IN PLACE, HOT ENGINE
EXHAUST IS DIRECTED OUT THE OPENING. THIS
HOT EXHAUST, DEPENDING ON THE INSTALLATION, COULD BE DIRECTED TO AREAS NOT ABLE
TO WITHSTAND THE EXTREME HEAT SUCH AS
WOODEN FLOOR BOARDS OR OTHER FLAMMABLE MATERIAL. THIS COULD RESULT IN A FIRE.
CLEANING THE GENERATOR
Keep your generator set as clean and dry as possible. Dirt
and moisture that are permitted to accumulate on electrical
windings have an adverse affect on the insulation resistance
of those windings.
DANGER: BATTERY ELECTROLYTE FLUID IS AN
EXTREMELY CAUSTIC SULFURIC ACID SOLUTION
THAT CAN CAUSE SEVERE BURNS. DO NOT
PERMIT FLUID TO CONTACT EYES, SKIN, CLOTHING, PAINTED SURFACES, ETC. WEAR
PROTECTIVE GOGGLES, PROTECTIVE CLOTHING
AND GLOVES WHEN HANDLING A BATTERY. IF
YOU SPILL THE FLUID, FLUSH THE AFFECTED
AREA IMMEDIATELY WITH CLEAR WATER.
Moisture that is allowed to remain in contact with windings will
be retained in voids and cracks of the windings. Dirt makes
the problem worse, since it tends to hold the moisture into contact with the windings. Salt, as from sea air, worsens the
problem since it tends to absorb moisture from the air. The
combination of salt and moisture makes a good electrical conductor.
DANGER: DO NOT USE ANY JUMPER CABLES
OR BOOSTER BATTERY TO CRANK AND START
THE GENERATOR ENGINE. IF ANY BATTERY HAS
DISCHARGED, REMOVE IT FOR RECHARGING.
CAUTION! Do NOT use a forceful spray of water to
clean the generator. Water will enter the generator
interior and cause problems, and may also contaminate the generator fuel system.

MAJOR SERVICE MANUAL
• Remove spark plug and pour about two or three tablespoons of clean, fresh engine oil into spark plug threaded
opening. Crank engine several times to distribute oil, then
install and tighten spark plug.
• Remove the battery and store in a cool, dry room on a
wooden board. Never store the battery on concrete or earth
floors.
• Clean and wipe the entire generator.
To obtain a service manual for your generator, order it from
your dealer/distributor or contact the factory. Be sure to identify your MODEL NUMBER and SERIAL NUMBER.
DRIVE BELT
The engine drives the generator rotor by means of a pulley
and drive belt arrangement. The drive belt and pulleys are warranted for the life of the generator. Drive belt tension was
properly adjusted before the unit was shipped from the factory. If you suspect that drive belt tension is incorrect, contact
an authorized service facility.
RETURN THE UNIT TO SERVICE
AFTER STORAGE
To return the unit to service after storage, proceed as follows:
• Check tag on engine for oil viscosity and classification.
Verify that the correct recommended oil is used in engine.
If necessary, drain and refill with proper oil.
• Check battery. Fill all cells to the proper level with distilled
water. DO NOT USE TAP WATER IN THE BATTERY.
Recharge battery to 100% state of charge, or, if defective,
replace the battery.
• Turn OFF all electrical loads, add fuel if necessary, then start
the engine.
• Let the engine warm up.
• Apply electrical loads to at least 50% of the unit’s rated
wattage capacity.
• When engine is thoroughly warmed up, shut it down.
THE GENERATOR IS NOW READY FOR SERVICE.
EXERCISING THE GENERATOR
Generac recommends that you start and operate the generator at least once every seven days. Let the unit run for at least
30 minutes to “exercise” the engine.
OUT OF SERVICE PROTECTION
If you cannot exercise the generator every seven days and it
is to be out of service longer than 30 days, prepare the generator for storage as follows:
• Start the engine and let it warm up.
• Close the fuel shutoff valve in the fuel supply line and let
the engine “run out of fuel.”
• While the engine is still warm from running, drain the oil completely. Refill crankcase with SAE 10W30 oil having API
classification “For Service SF.”
• Attach a tag to the engine indicating the viscosity and classification of the oil in the crankcase.

CALIFORNIA EMISSION CONTROL WARRANTY STATEMENT
YOUR WARRANTY RIGHTS AND OBLIGATIONS
The California Air Resources Board ("CARB") and Generac Corporation are pleased to explain the Emission Control System Warranty on your new recreational vehicle generator engine. In California, new recreational vehicle generator must be designed,
built and equipped to meet the State's stringent anti-smog standards. Generac Corporation will warrant the emission control
system on your recreational vehicle generator for the periods of time listed below provided there has been no abuse, neglect,
unapproved modification, or improper maintenance of your recreational vehicle generator engine.
Your emission control system may include parts such as the carburetor, ignition system and exhaust system. Also included may
be the compression release system and other emission-related assemblies.
Where a warrantable condition exists, Generac Corporation will repair your recreational vehicle generator engine at no cost to
you for diagnosis, parts and labor.
MANUFACTURER'S EMISSION CONTROL SYSTEM WARRANTY COVERAGE:
Emissions control systems on 1995 and later model year recreational vehicle generator are warranted for two years as hereinafter
noted. If, during such warranty period, any emission-related part on your engine is defective in materials or workmanship, the
part will be repaired or replaced by Generac Corporation.
OWNER'S WARRANTY RESPONSIBILITIES:
As the recreational vehicle generator engine owner, you are responsible for the performance of the required maintenance listed
in your owners manual. Generac Corporation recommends that you retain all receipts covering maintenance on your recreational
vehicle generator engine, but Generac Corporation will not deny warranty solely due to the lack of receipts or for your failure
to provide written evidence of the performance of all scheduled maintenance.
As the recreational vehicle generator engine owner, you should, however, be aware that Generac Corporation may deny you
warranty coverage if your recreational vehicle generator engine or a part thereof has failed due to abuse, neglect , improper
maintenance or unapproved modifications.
You are responsible for presenting your recreational vehicle generator engine to a Generac Corporation Authorized Service Outlet
as soon as a problem exists. The warranty repairs should be completed in a reasonable amount of time, not to exceed 30 days.
Warranty service can be arranged by contacting either a Generac Corporation Authorized Service Outlet or by contacting Generac Corporation at:
GENERAC CORPORATION PH: (414) 544-4811
P.O. BOX 8 FAX: (414) 544-0179
WAUKESHA, WI 53187
IMPORTANT NOTE: This warranty statement explains your rights and obligations under the Emission Control System Warranty
("ECS Warranty") which is provided to you by Generac Corporation pursuant to California law. See also the Generac Corporation Limited Warranties for Generac Corporation which is enclosed herewith on a separate sheet and also is provided to you by
Generac Corporation. The ECS Warranty applies only to the emission control system of your new engine. To the extent that there
is any conflict in terms between the ECS Warranty and the Generac Corporation Warranty, the ECS Warranty shall apply except
in any circumstances in which the Generac Corporation Warranty may provide a longer warranty period. Both the ECS Warranty and the Generac Corporation Warranty describe important rights and obligations with respect to your new engine.
Warranty service can only be performed by a Generac Corporation Authorized Service Outlet. At the time of requesting warranty service, evidence must be presented of the date of the sale to the original purchaser. The purchaser shall pay any charges
for making service calls and/or for transporting the products to and from the place where the inspection and/or warranty work
is performed. The purchaser shall be responsible for any damage or loss incurred in connection with the transportation of any
engine or any part(s) thereof submitted for inspection and/or warranty work.
IF YOU HAVE ANY QUESTIONS REGARDING YOUR WARRANTY RIGHTS AND RESPONSIBILITIES, YOU SHOULD CONTACT GENERAC CORPORATION AT 1-800-222-3136
EMISSION CONTROL SYSTEM WARRANTY
Emission Control System Warranty ("ECS Warranty") for 1995 and Later Model Year recreational vehicle generator:
A.Applicability: This warranty shall apply to 1995 and later model year recreational vehicle generator. The ECS Warranty Period
("ECS Warranty Period") shall begin on the date the new engine or equipment is delivered to its original, end-use purchaser
and shall begin on the date the new engine or equipment is delivered to its original, end-use purchaser and shall continue for
24 consecutive months thereafter.
B. General Emissions Warranty Coverage: Generac Corporation warrants to the original, end-use purchaser of the new engine or
equipment and to each subsequent purchaser that each of its recreational vehicle generator is:
1. Designed, built and equipped so as to conform with all applicable regulations adopted by the Air Resources Board pursuant
to its authority, and
2. Free from defects in materials and workmanship which, at any time during the ECS Warranty Period, will cause a warranted
emissions - related part to fail to be identical in all material respects to the part as described in the engine manufacturer's
application for certification.
C. The ECS Warranty only pertains to emissions-related parts on your engine, as follows:
1. Any warranted, emissions-related parts which are 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 Corporation according to Subsection (4) below. Any such part repaired or replaced under
the ECS Warranty shall be warranted for any remainder of the ECS Warranty Period.
2. Any warranted, emissions-related part which is scheduled only for regular inspection as specified in the Owner's Manual shall
be warranted for the ECS Warranty Period. A statement in such written instructions 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 any remainder of the ECS Warranty Period.
3. Any warranted, emissions-related part which 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 Corporation 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 ECS Warranty Period prior to the first scheduled replacement point for such emissions-related 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 Corporation Authorized Service Outlet.
5. The owner shall not be charged for diagnostic labor which leads to the determination that a part covered by the ECS Warranty is in fact defective, provided that such diagnostic work is performed at a Generac Corporation Authorized Service Outlet.
6. Generac Corporation shall be liable for damages to other original engine components or approved modifications proximately
caused by a failure under warranty of any emission-related part covered by the ECS Warranty.
7. Throughout the ECS Warranty Period, Generac shall maintain a supply of warranted emission-related parts sufficient to meet
the expected demand for such emission-related parts.
8. Any Generac Corporation authorized and approved emission-related replacement part may be used in the performance of
any ECS warranty maintenance or repairs and will be provided without charge to the owner. Such use shall not reduce Generac Corporation ECS warranty obligations.
9. Unapproved add-on modified parts may not be used to modify or repair a Generac Corporation engine. Such use voids this
ECS Warranty and shall be sufficient grounds for disallowing an ECS Warranty claim. Generac Corporation shall not be liable
hereunder for failures of any warranted parts of a Generac Corporation engine caused by the use of such an unapproved
add-on or modified part.

Generac’s Three-Year Limited Warranty For Recreational Vehicle NP Generators
GENERAC warrants to the original purchaser that its generators will be free from defects in materials or workmanship for the
period set forth below from the date of original purchase. During said warranty period, Generac will, at its option, repair or replace
any part which, upon examination by Generac or Generac Authorized Distributors and/or Dealers, is found to be defective under
normal use and service.
This warranty is effective only upon Generac’s receipt prior to expiration of the warranty period of a completed Warranty Registration Card. This card is the only valid registration identification and must be presented at time of service. Claims will not be
accepted without presentation of Registration Card.
THREE YEAR WARRANTY SCHEDULE
1. All NP Series generators used in a recreational vehicle shall be warranted for a period of three (3) years or 2,000
hours of operation, whichever occurs first. All parts, labor, removal and reinstallation shall be covered for the first
two years. Parts and labor on selected generator and engine parts shall be covered during the third year or 2,000
hours, whichever occurs first. These selected parts are limited to: the main Rotor and Stator, Computer Control
board (if applicable) with regard to the generator; the Cylinder Block, Cylinder Head, Crankshaft, Piston, Valve,
Valve Lifter, and Manifolds with regard to the engine.
2. The drive train belt and pulleys (if so equipped) on NP air-cooled generator used in recreational vehicles shall be
warranted against failure due to defective materials or normal usage for the life of the generator. For the original
owner, this drive train warranty shall include parts and labor plus $50.00 payment upon return of the failed belt or
pulley by the original owner. For succeeding owners, this power train warranty shall cover belt or pulley parts only.
3. Rental units, demonstrators, prime power, or commercial applications, such as construction or utility, are warranted

There is no other express warranty. Generac hereby disclaims any and all implied warranties, including but not limited to those
of merchantability and fitness for a particular purpose to the extent permitted by law. The duration of any implied warranties which
cannot be disclaimed is limited to the time period (one year) as specified in the express warranty. Liability for consequential, incidental or special damages under any and all warranties is excluded to the extent permitted by law. Some states do not allow
limitations on how long an implied warranty lasts, or the exclusion or limitation of incidental or consequential damages, so the
above limitations or exclusions may not apply to you. This warranty gives you specific legal rights and you may also have other
rights, which vary from state to state.
For service, see your nearest GENERAC authorized warranty service facility or call 1-800-333-1322. Warranty service can be
performed only by a GENERAC authorized service facility. This warranty will not apply to service at any other facility. At the time
