Model No. 00916-1 Series NP-50G
Printed in U.S.A.
Generac NP-50G Recreational Vehicle Generator
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.
WARNING:
The engine exhaust from this product
contains chemicals known to the State
of Caiifomia to cause cancer, birth
defects, or other reproductive harm.
Study these SAFETY RULES carefully before installing, operating or ser
vicing this equipment. Become famiiiar with the Owner’s Manual and with
the generator. The generator can operate safely, effidentty 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.
Generac cannot possibly antidpate every possible drcumstance that might
involve a hazard. The warnings in this Manual and on tags and decals affixed
to the unit are therefore, not allH’ndi^ive. 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.
• For fire safety, the 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.
A The Recreational Vehicle Generator produces extremely high and
dangerous electrical voltages and can cause dangerous, and possi
bly fatal, electrical shock. Avoid contact with bare wires, terminals, etc.
while the unit is running. If you must work around an operating gen
erator, stand on an insulated, dry surface to reduce slwck hazard.
Never work on this equipment or handle any electrical device while
standing in water, while barefoot, or while hands or feet are wet Dan
gerous electrical shock will result
• 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 con
ductor to any generator part that might be renKtved or disasserffeled during
routine maintenance. If the grounding conductor must be replaced, use
only a flexfele conductor that is of No. 8 AWG copper wire minimum.
• Keep hands, feet clothing, etc., away from drive belts, fans and other
moving parts of this equipment Never remove any drive belt or fan
^ards while the unit fe operating.
• Inspect the generator periodically. Repair or replace all damaged or
defective parts immediately.
A 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.
• 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 mi^
affect safety or compliance with applicable codes and standards.
A The generator engine gives off DEADLY carbon monoxide gas through
its exhaust system. This dangerous gas, if breathed in sufficient con
centrations, can cause unconsdousness 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 nnight render the system unsafe or in non-compliance with
such codes and standards. The generator compartment must be com
pletely vapor sealed from vehide Interior. There must be no possibility
of exhaust fumes entering the vehicle interior. Never operate this
equipment with a leaking or defedive exhaust system.
• 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.
• Do not smoke around the generator. Wipe 14) any fuel, or oil spills imme
diately. Never leave dly or fuel soated rags in the generator compartment
or on the generator itself. Keep the area around the generator dean 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 equip
ment in any manner that might obstruct air and ventilation openings. Such
openings must be kept dear and unobstructed.
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 if). Disconnect the cable from
the battery post indicated by a NEGATIVE, NEG or (-) first Reconnect
that cable last

GENERATOR APPUCABILITY
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 pertain
ing to its application, write or call the factory. Do not use the
unit until you have been advised by a competent authority.
DANGER: For fire safety, the generator must have
been property installed in compliance with (1)
ANSI 119.2-1975/NFPA 501C-1974 “Standard for
Recreational Vehicles, Part III, “Installation of Elec
trical Systems.” The generator also must have
been installed in strict compliance with the manu
facturer’s detailed installation instructions. After
installation, do nothing that might render the unit
in non-compliance with such codes, standards and
instructions.
You can use this generator to supply electrical power for oper
ating 120/240 volts, single phase, 60 Hertz, AC electrical
loads. These loads can require up to 4800 watts of (4.8kW)
of power, but cannot exceed 40 AC amperes of current at 120
volts or exceed 20 AC amperes at 240 volts.
CAUTION: Do not overload the generator. Some
installations may require that electrical loads be
alternated to avoid overloading. Applying exces
sively high electrical loads ntay 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, multi
ply 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.
An INSTALLATION MANUAL was shipped with the genera
tor. That manual contains manufacturer’s instructions and
recommendations for installing the unit into a recreational
vehicle. After installation, installers should forward the Instal
lation Manual to Owners/Operators for their information.
Owners/Operators have the responsibility to make sure that
nothing is done that might render the Installation unsafe or in
non-compliance with applicable codes, standards and instruc
tions.
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 copy
ing and posting GENERAL SAFETY RULES in potential hazard
areas of the vehicle. Stress safety to all operators and poten
tial operators of this equipment.
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 con
nection system. Note, however, that neutral is grounded.
The generator may have been installed so that units power
120 volts AC loads (Figure 1); or you can wire them to con
nect both 120 and/or 240 volts AC electrical loads. Be sure
to install jumper wire between the circuit breakers when recon
necting for 120/240 volts. Refer to the Installation Manual for
more information.
Figure 1 — Connections for 120 Volts Only
INSTALLATION
This Owner's Manual has been prepared under the assump
tion that a competent, qualified technician installed the
generator. We also assume the installer complied with all
applicable codes, standards and regulations pertaining to
installation.

Before starting a coid engine (if it has not been started in more
than two weeks), you must press this switch for approximateiy
5 seconds to bring fuel from the tank to the carburetor. This
rocker type switch springs back into its originai position when
you reiease it.
START/STOP SWITCH
NOTE: If the Series NP-50G has been reconnected for dual
voltage AC output (120/240 volts), you can install line break
ers having an amperage rating that is different than stated
above. The repiacement line breakers consist of two sepa
rate breakers with a connecting piece between the breaker
handies (so that both breakers wiil operate at the same time).
If the unit is reconnected for dual voltage, it is no longer RVIA
listed.
OPTIONAL REMOTE
START/STOP PANEL
A remote mounted Start/Stop Panel is available, which aliows
you to start and stop the generator engine convenientiy from
inside the vehicie. Figure 3 shows the Model 9042 remote
panel which includes (a) start/stop switch and (b) a genera
tor run lamp.

Generac NP-50G Recreational Vehicle Generator
AUTOMATIC CHOKE
The engine is equipped with an automatic choke that consists
of two main components — choke soienoki and prechoke.
■ CHOKE SOLENOID__________________________
During engine cranking (start/stop switch at START), a solid
state choke module signals the choke solenoid to actuate and
cycle (choke on/choke off) until the engine starts. The choke
solenoid thus opens and closes the cartxjretor choke valve only
when the engine is cranking. When the engine starts, the choke
stops cycling.
■ PRECHOKE
The choke system also has a temperature sensitive metal strip
that adjusts choke valve angle according to ambient temper
atures (i.e., in cold ambient temperatures, choke valve closes
more). Once the engine starts, an element heats the tem
perature-sensitive strip to a normal operating condition, opening
the choke valve. This may take about 3 minutes in cooler
weather.

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 tech
nician or installation contractor.
■ INSTALLATION
Generator installation must have been properly completed so
it complies with all applicable codes, standards and regula
tions and with the manufacturer's recommendations.
■ ENGINE LUBRICATION
Have engine crankcase properly serviced with recommended
oil before starting. Refer to MAINTENANCE and SPECIFI
CATIONS sections for oil servicing procedures and
recommendations.
CAUTION: Any attempt to crank or start the engine
before you have property serviced It with the recom
mended oil may result in an engine failure.
FUEL SUPPLY
The engine must have adequate supply of proper fuel to oper
ate. Before starting, check that sufficient fuel is available.
_____________________________
______________________
NOTE: On some installation, the generator engine may “share"
the vehicles gasoline fuel tank with vehicle engine. Some instal
lations may provide separate fuel tanks for generator and
vehicle engine.
■ COOLING AND VENTILATING AIR
Air inlet and outlet openings in generator compartment must
be open and unobstructed for continued proper operation.
Without sufficient cooling and ventilating air flow, engine-gen
erator quickly overheats which causes it to shutdown or may
damage the generator.
■ ENGINE EXHAUST CAS______________________
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, rnight permit exhaust gases
to enter the vehicle.
DANGER: The generator engine gives off DEADLY
carbon monoxide gas through its exhaust system.
This dangerous gas, if breathed in sufficient con
centrations, 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) weak
ness and sleepiriess. IF YOU FEEL ANY OF THESE
SYMPTOMS, MOVE INTO FRESH AIR IMMEDI
ATELY. IF SYMPTOMS PERSIST, GET MEDICAL
HELP.
STARTING THE GENERATOR
IMPORTANT; Read the vehicle manufacturer’s instructions.
The owner/operator should become familiar with the vehicle
in which this 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.
To start the generator from either the generator control panel
or from the optional Remote Panel, proceed as follows on page
9.
Recreational Vehicle Generator
8
Generac NP-50G Recreational Vehicle Generator
1. Turn OFF electrical loads, using whatever means provided
in your vehicle (such as a main line circuit breaker or trans
fer switch).
NOTE: If starting from the generator control panel, turn OFF
loads by setting the generators main circuit breaker to “OFP
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.
2. If you have not started the engine in more than two weeks,
press the Fuel Pump 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.
CAUTION: If the engine does not start after it has
been cranking for 15 seconds, release the
start/stop switch and try again. Hoiding the switch
for ionger 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).
STOPPING THE GENERATOR
1. Turn OFF all electrical loads, using whatever means pro
vided (such as a main circuit breaker or transfer switch).
2. Let generator run at no-load for a.few minutes, to stabilize
internal engine generator temperatures.
3. Place start/stop switch in its STOP position.
If electrical loads are applied at reduced operating speeds, such
loads imposed on the engine when sufficient power is not avail
able may shorten engine life. Never turn ON electrical loads
until after the generator engine has started and stabilized
ON-speed.
SUMMER/WINTER
HEAT RISER SYSTEM
Under certain weather conditions, it is possible for ice to form
in the venturi area of the carburetor. This condition can be
very dangerous because it can prevent the governor system
from functioning properly, which results in a “run-away” engine.
The most common weather conditions leading to this problem
are temperatures in the range of 25® to 35°F, along with high
humidity. This ice formation can also be attributed to the load
being applied during these weather conditions. Generators
running with no load or light loads applied usually have the
most problems. The operator is responsible for adjusting the
heat riser system for weather conditions.
■ CONSTRUaiON AND FUNCTION OF
HEAT RISER SYSTEM
The system consists of the following components:
• Plastic collector box that is attached to the back side of the
air filter base.
• “Flapper” valve and lever assembly.
• Corrugated aluminum tube that goes from the above plas
tic box, through engine enclosure sheet metal and nestled
very close to exhaust manifold.
Place the lever in the “Summer” position (Figure 4), to draw
air into the filter box directly from the compartment through
the tube on the right side of the plastic box.
__________________
APPLYING LOADS TO GENERATOR
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.
■ 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.
Recreational Vehicle Generator
Figure 4 — Adjustment Summer/Winter Lever
Generac NP-50G Recreational Vehicle Generator
Place the lever in the “Winter” position (25 - 30°F), so the hole
in the plastic tube is covered and the aluminum tube is opened.
As mentioned previously, the end of the aluminum tube is
positioned very close to the exhaust manifold. As the engine
is running and the exhaust system heats up, heated air is dravwi
through the aluminum tube, which helps to prevent ice from
forming on the carburetor.
■ DO NOT OVERLOAD THE GENERATOR
You can read the rated wattage/amperage capacity of your gen
erator on the generator data decal (see “Identification Record”
on Page 3).
Applying electrical loads in excess of the unit's rated capac
ity will cause the engine-generator to automatically shutdown.
To avoid overloading, add up the wattage of all connected elec
trical lighting, appliance, tool and motor loads. This total should
not be greater than the generator's rated wattage capacity.
• 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.
• Induction type motors (such as those that run the vehicle's
furnace fan, refrigerator, air conditioner, etc.) need about 2-
1/2 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.
Rrst, 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.
ADDITIONAL INFORMATION
This section discusses some the the engine protective devices,
overload protection and breaking in a new generator.
■ AUTOMATIC LOW OIL PRESSURE
SHUTDOWN
The engine is equipped with a normally-closed (N.C.) oil pres
sure switch (Figure 5). 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 high temperature switch (Figure 5) with normally-open (N.O.)
contacts is mounted near the oil filter. If engine temperature
were to exceed about 284°F (lAOX), the switch contacts
close and the engine shuts down.
■ FIELD BOOST
The Controller Circuit Board houses a field boost diode and
resistor which are not part of the automatic choke circuit.
These two components are part of a “field boosf circuit (Rgure
6). During engine cranking oniy, a positive DC (battery) volt
age is deiivered 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. Fiashing of
the fieid each time the generator starts makes sure that a suf
ficiently strong magnetic field is available to produce “pick-up”
voltage in the stator windings.
Figure 6 — Field Boost Circuit

■ OVERVOLTAGE PROTEaiON
A solid state voltage regulator (Figure 7) controis the gener
ator's AC output voitage. This regulator suppiies an excitation
current to the rotor. By regulating the rotor’s excitation cur
rent, the strength of its magnetic fieid is reguiated and, in turn,
the voltage delivered to connected electrical loads is controlied. When the AC frequency is 60 Hz, voltage is reguiated
at 120 volts (voltage-to-frequency ratio is 2-to-1).

■ 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 per
formance. During this 25-hour break in period, foiiow this
procedure:
• Run the unit at varying electrical loads, to help seat engine
piston rings properiy.
• Check engine oii levei frequently. Add oil if needed. It is
normal for the generator engine to consume more oil than
is normai until the piston rings have properly seated.
• For the 75-hour operation foilowing the break in period,
avoid light electrical loads. Load the generator at 50% (or
more) of its rated wattage capacity. Repeated iight loads
during these 75 hours can cause improper seating of engine
piston rings, resulting in blowby and high oii consumption.
• After operating the unit for 25 hours, complete the tasks rec
ommended under “25-Hour Check Up."

Generac NP-50G Recreational Vehicle Generator
25-HOUR CHECK UP
After the 25-hour break-in period, contact an authorized ser
vice facility for the foilowing maintenance. The vehicie owner
is responsible for any charges:
• Change engine crankcase oil and oil filter.
Check oil level.
• Inspect cooling and ventilation openings.
Check engine carburetor adjustments.
• Check engine ignition system.
• Inspect entire electrical system.
• Inspect the engine exhaust system.
■ AHENTION REQUIRED AFTER
SUBMERSION
If the recreational vehicle generator has been submerged in
water, it must NOT be started or operated. Following any sub
mersion in water, have an authorized Generac Service facility
thoroughly clean and dry the generator.
______________________________
■ OPERATION IN HIGH GRASS
OR BRUSH
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 system becomes extremely hot during operation and
remains hot for a long time after it has shut down.
_________________________________
■ OPERATING PRECAUTIONS
Never operate the generator set while the vehicle is parked
over dry leaves, dry grass or any other combustible sub
stance. The generator’s exhaust system becomes extremely
hot and can cause fire if it is too close to combustible mate
rials.
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 other enclosed area. Never operate the generator
if it has a leaky exhaust system. Close windows in the vicin
ity of the generator exhaust outlet and take any other steps
to prevent exhaust gases from entering rooms or areas occu
pied by people or animals.
_________________
■ 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 gen
erator 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 prob
lem 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 mois
ture, when combined, for a good electrical conductor.

FUEL REQUIREMENTS
The “NP” series generator is equipped with a gasoiine fuei
system. Specific installations may provide either a separate
fuel tank for the generator, or the generator may “share” the
vehicle engine’s fuel tank.
NOTE: Some installations using a “shared” fuel tank may have
a generator fuel pickup tube that is shorter than the vehicle
engine’s pickup tube. Such an arrangement causes the gen
erator engine to “run out of gas” whiie adequate fuel for the
vehicle remains in the tank.
To reduce lead and carbon deposits use high quality
UNLEADED gasoline with the generator. Leaded REGULAR
grade gasoline is an acceptable substitute.
NOTE: Using "Unieaded” gasoline contributes to longer
engine valve life by reducing iead and carbon deposits.
CAUTION: Generac does not recommend using
any gasoline containing alcohol (such as “gasohoi”). If you use any gasoline containing alcohol,
It must not contain more than 10 percent ethanol
and it must be removed from the generator during
storage. Do NOT use any gasoline containing
methanol. If you use gasoline with alcohol,
inspect more frequently for fuel leaks and other
abnormalities.
ENGINE OIL REQUIREMENTS
Use only high quality detergent oil rated with API service clas
sification SF, SG, or SH. The recommended oil weights include
the following:
• During summer months: SAE 30. An acceptable substitute
isSAE10W-30.
• During winter months: SAE5W30. DO NOT USE SAE 10W40.
Crankcase and oil filter capacity is about 1400ml or about 1.5
U.S. quarts. Use no special additives. See “Maintenance” sec
tion for oil level check and fill procedures.

Generac NP-50G Recreational Vehicle Generator
FUEL FILTER
Remove and replace fuel filter (Figure 14) every 100 hours of
operation or once each year, whichever comes first.
Figure 14 — Fuel Filter
SPARK ARRESTOR MUFFLER
If the generator is not equipped with a spark arrestor exhaust
muffler and is to be used on any forest covered, brush cov
ered 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.
For assistance in ordering, installing and maintaining spark
arrestor exhaust mufflers, contact your nearest authorized
service facility.
Exhaust mufflers supplied by Generac are spark arrestor
types. Generac exhaust muffler for recreational vehicle gen
erators do not have a spark arrestor screen, but are of the more
efficient “toroid” or “swirl” type. To remove carbon and com
bustion 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.
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.
Moisture that is allowed to remain in contact with windings wiii
be retained in voids and cracks of the windings. Dirt makes
the probiem worse, since it tends to hold the moisture into con
tact with the windings. Salt, as from sea air, worsens the
probiem since it tends to absorb moisture from the air. The
combination of sait and moisture makes a good electricai con
ductor.
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 contam
inate the generator fuel system.
BAHERY
Ail lead-acid storage batteries wili discharge when not in use.
The generator battery shouid be inspected as follows:
ONCE WEEKLY
Inspect battery posts and cables for tightness, corrosion.
Ciean and/or tighten as needed.
Aiso check battery fluid levei, and, if necessary, fiil with DIS
TILLED WATER ONLY. DO NOT USE TAP WATER IN
BAHERY.
EVERY SIX MONTHS
Have battery state of charge and condition checked. This
should be done with automotive type battery hydrometer.
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.

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 spailc can ignite the gas
and cause an explosion. Such an explosion can
shatter the battery and cause blindness or o№er
injury. Any area that houses a storage battery
must be properly ventilated. Do not allow smok
ing, open flame, sparks or any spark producing
tools or equipment near the battery.
Generac NP-50G Recreational Vehicle Generator
DANGER: Battery electrolyte fluid is an extremely
caustic sulfuric acid solution that can cause
severe bums. Do not permit fluid to contact eyes,
skin, clothing, painted surfaces, etc. Wear protec
tive goggles, protective clothing and gloves when
handling a battery. If you spill the fluid, flush the
affected are immediately with dear water.
DANGER: Do not use any jumper cables or
booster battery to crank and start the generator
A
engine. If any battery has discharged, remove It
for recharging.
MAJOR SERVICE MANUAL
To obtain a service manual for your generator, order it from
your dealer/distributor or contact the factory. Be sure to iden
tify your MODEL NUMBER and SERIES.
DRIVE BELTS
The engine drives the generator rotor by means of a pulley
and drive belt arrangement. The drive belt and pulleys are war
ranted for the life of the generator. Drive belt tension was
properly adjusted before the unit was shipped from the fac
tory. If you suspect that drive belt tension is incorrect, contact
an authorized service facility.
EXERCISING THE GENERATOR
Generac recommends that you start and operate the gener
ator at least once every seven days. Let the unit run for at
least 30 minutes to “exercise" the engine.
OUT OF SERVICE PROTEQION
If you cannot exercise the generator every seven days and it
is to be out of service longer than 30 days, prepare the gen
erator for storage as follows:
• While the engine is still warm from running, drain the oil com
pletely. Refill crankcase with SAE 10W30 oil having API
classification “For Service SF.”
• Attach a tag to the engine indicating the viscosity and clas
sification of the oil in the crankcase.
• Remove spark plug and pour about two or three table
spoons 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.
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 BAHERY.
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 GENEFWOR IS NOW READY FOR SERVICE.
• Start the engine and let it warm up.

YOUR WARRANTY RIGHTS AND OBUGATIONS
The California Air Resources Board CCARB") and Generac Corporation are pleased to explain the Emission Control System Wa

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, improp
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.

tion 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 War
ranty 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 war
ranty 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

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 defect 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 nec
essary" 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 War
ranty 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 Gen
erac 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.
