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 California to cause cancer, birth
defects, or other reproductive harm.
Study these SAFETY RULES carefully before installing, operating or ser
vicing 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.
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.
• 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.
^ 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 shock hazard.
A 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 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.
• 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.
* •
• 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 might
affect safety or compliance with applicable codes and standards.
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. This exhaust
system must have been properly installed, in strict compiiance with
appiicable 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 com
pletely 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.
• 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 up any fuel or oil spills imme
diately. 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 equip
ment in any manner that might obstruct air and ventilation openings. Such
openings must be kept clear and unobstructed.
A 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.

Generac NP-50LPG Recreational Vehicle Generator
GENERATOR APPLICABILITY
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 properly installed in compliance with (1)
A
ANSI 119.2-1975/NFPA 501C-1974 “STANDARD
FOR RECREATIONAL VEHICLES, PART ill,
“INSTALLATION OF ELECTRICAL SYSTEMS.” The
generator must also have been installed in strict
compliance with the manufacturer’s detailed instal
lation 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 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.
CAUTION: Do not overload the generator. Some
installations may require that electrical loads be
alternated to avoid overloading. Applying exces
sively 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, multi
ply volts times amps to obtain watts (volts x amps
s watts). Some electric motors require more watts
of power (or amps of current) for starting than for
continuous operation.
Owners/Operators must make sure to do nothing that might
render the installation unsafe or in noncompliance with applic
able codes, standards and instructions. They should be sure
the unit has been installed to allow adequate ventilation for cool
ing and exhaust air.
SAFETY
Before attempting to use the generator set, carefully read
GENERAL SAFETY RULES inside the cover of this Manual.
Comply strictly virith 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 CONNEQION
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 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.
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.

NOTE: If the Series NP-50LPG 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 replacement line breakers consist of two sepa
rate breakers with a connecting piece between the breaker
handles (so that both breakers will 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 allows
you to start and stop the generator engine conveniently from
inside the vehicle.
Figure 3 — Optional Remote Panel (Model 9042)
FUEL PRIMER
Before starting a cold engine (if it has not been started in more
than two weeks), you must press this switch for approximately
5 seconds to bring fuel from the tank to the fuel regulator. This
rocker type switch springs back into its original position when
you release it.
START/STOP SWITCH
To crank and start the engine, hold this switch at its START
position. Release the switch when the engine starts. To stop
an operating engine, press and hold the switch in its STOP
position until the engine shuts off. The switch center position
is the RUN position.
FUSE
Protects the engine DC control circuit against electrical over
load. If the fuse element has melted open due to overloading,
the engine cannot be cranked. If you must replace it, use only
an identical replacement fuse.
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 properly serviced it with the recom
mended oii may resuit 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.
■ 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, the enginegenerator quickly overheats which causes it to shutdown and
it could 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, might 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) weakness and sleepiness. IF YOU FEEL ANY
OF THESE SYMPTOMS, MOVE INTO FRESH AIR
IMMEDIATELY. IF SYMPTOMS PERSIST, GET MED
ICAL HELP.
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.
To start the generator from either the generator control panel
or from the optional Remote Panel, proceed as follows:
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 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 cir
cuit 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 Primer switch and hold it for about 30 seconds
to prime fuel system. However, if the engine is warm, skip Step
2.
Recreational Vehicle Generator

Generac NP-50LPG Recreational Vehicle Generator
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 longer than 15 seconds can damage the starter
motor.
4. Let the engine run at no-load tor 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 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.
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.
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 stabi
lized ON-speed.
■ 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.
‘ Allow 2-1/2 times the listed watts for starting these devices.

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.
ADDITIONAL INFORMATION
This section discusses some the the engine protective devices,
overload protection and breaking in a new generator.
The engine is equipped with a normally-closed (N.C.) oil pres
sure 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
FIELD BOOST
The Controller Circuit Board houses a field boost diode and
resistor which are part of a lield 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 Hashes the field" whenever it is started. Flashing of the
field each time the generator starts makes sure that a suffi
ciently strong magnetic field is available to produce "pick-up"
voltage in the stator windings.
Figure 5 — Field Boost Circuit
CLOSEST TO
BEADING
A temperature switch (Figure 4) with normally-open (N.O.) con
tacts 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.
Figure 4 — Switches for Engine
Safety Shutdown
■ OVERVOLTAGE PROTEaiON
A solid state voltage regulator (Figure 6) controls the gener
ator's AC output voltage. This regulator supplies an excitation
current to the rotor. By regulating the rotor's excitation cur
rent, 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 reg
ulated 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 pro
tection circuit.” This circuit prevents troublesome surges in the
generator AC output voltage. Voltage surge is a common cause
of damage to electronic equipment.
■ 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, follow this
procedure:
• 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 rec
ommended under “25-Hour Check Up.”
■ 25-HOUR CHECK UP
After the 25-hour break-in period, contact an authorized ser
vice 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.
________________________
________________
■ 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.
■ 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.
________________________________
_________________
■ 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 insula
tion 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 wind
ings. 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.
■ OPERATION IN HIGH GRASS
OR BRUSH
WARNING; Never operate the generator while the
vehicle is parked in high grass, weeds, brush or
A
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 t

FUEL REQUIREMENTS
The “NP” series generator is equipped with a liquefied petro
leum (LP) gas fuel system. LP gas is usually supplied as a
liquid in pressure tanks.
“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 temper
ature 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 suffi
ciently 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 tem
peratures 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.
FUEL CONSUMPTION
(CUBIC FEET PER HOUR)
The following lists the approximate amount of fuel the unit con
sumes at 100% rated load. Actual fuel consumption may
vary depending on BTU content of fuel, applied load, ambi
ent conditions, engine condition, etc.
Propane
................................................
47 cubic ft. per hour
ENGINE OIL REQUIREMENTS
Use only high quality detergent oil rated with API ser
vice classification SR SG or SH. The recommended oil
weights include the following:
• During summer months: SAE 30. An acceptable substitute
isSAE10W-30.
• During winter months: SAE 5W30. DO NOT USE SAE
10W-40.
Crankcase and oil filter capacity is about 1400ml or
about 1.5 U.S. quart. Use no special additives. See
“Maintenance” section for oil level check and fill proce
dures.
This section includes information about simple maintenance
which includes the following tasks.
• Checking engine oil level
• Changing engine oil
• Changing oil filter
• Clean or change the air cleaner
• Cleaning the air intake screen
• Cleaning spark plug
CHECKING ENGINE OIL LEVEL
Check engine crankcase oil level at least every eight hours of
operation, or before you use it.
Be sure the generator is as level as possible.
• Remove OIL DIPSTICK (Figure 7) and wipe it dry with clean,
lint-free cloth.
• Install and tighten oil dipstick then remove again.
• Oil level should be at the dipstick “FULL” mark. If necessary,
add oil to the “FULL” mark only. DO NOT FILL ABOVE THE
“FULL” MARK.
• Install and tighten oil dipstick before operating the engine.
NOTE: See “Engine Oil Requirements” on Page 12 for rec
ommended oils.
Figure 7 —Oil Dipstick and Oil Fill Cap
With engine still warm, remove oil drain cap from oil drain
hose (Figure 8). Drain oil completely into a suitable con
tainer.
Figure 8 — Location of Oil Drain Cap
• When oil has drained, install and tighten oil drain cap.
• Remove oil fill cap and fill crankcase with the recommended
oil (see Page 12). The engine crankcase can hold about 1.4
liters. DO NOT FILL ABOVE “FULL" MARK.
• Install and tighten oil dipstick and oil fill cap before operat
ing engine.
CHANGE OIL FILTER
Change engine oil filter after the first 25 hours of operation,
every 100 operating hours thereafter.
• Turn oil filter counterclockwise to remove (Figure 9).
• Coat gasket of new filter with engine oil.
• Turn new filter clockwise until its gasket contacts lightly with
the filter adapter. Then tighten with an additional 3/4 to one
turn by hand.
• Run engine and check for leaks.
NOTE: Check oil level and fill to full mark after checking for
leaks. Filter will retain some oil.
CHANGE ENGINE OIL
Change engine oil after the first 25 hours of operation (after
the 25-hour break-in period. Page 11). Thereafter, change oil
every 50 operating hours. Change oil more frequently if oper
ating consistently under heavy load or at high ambient
temperatures. To change oil, proceed as follows;
• Run engine for at least 5 minutes, then shut down.

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.
WARNING; Be sure to re-install the plug from the
muffler tightly. Engine vibration could cause a loose
A
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 flamma
ble material. This could result in a fire.
BAHERY
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.
Also check battery fluid level, and, if necessary, fill 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 an automotive type battery hydrometer.
DANGER: Storage batteries give off explosive
hydrogen gas. This gas can form an expiosive mix
A
ture around the battery for severai 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.

CLEANING THE GENERATOR
Keep your generator set as clean and dry as possible. Dirt
and moisture that are permitted to accumuiate on electrical
windings have an adverse affect on the insulation resistance
of those windings.
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 con
tact 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 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 conta
minate the generator fuel system.
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 area immediately with clear water.
DANGER; Do not use any jumper cables or
booster battery to crank and start the generator
engine. If any battery has discharged, remove it
from the vehicle 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 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 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 genera
tor 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:
• 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 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 oii.
• Check battery. Fill all cells to thé 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.
