SAFETY PRECAUTIONS
Thoroughly read the OPERATOR’S MANUAL
before operating the genset. Safe operation and
top performance can be obtained only when
equipment is operated and maintained properly.
The following symbols in this manual alert you to po-
tential hazards to the operator, service person and
equipment.
DANGER alerts you to an immediate hazard
which will result in severe personal injury or
death.
WARNING alerts you to a hazard or unsafe
practice which can result in severe personal in-
jury or death.
CAUTION alerts you to a hazard or unsafe
practice which can result in personal injury or
equipment damage.
Electricity, fuel, exhaust, moving parts and batteries
present hazards which can result in severe personal
injury or death.
GENERAL PRECAUTIONS
S Keep children away from the genset.
S Do not use evaporative starting fluids. They are
highly explosive.
S To prevent accidental or remote starting while
working on the genset, disconnect the nega-
tive (−) battery cable at the battery.
S Keep the genset and its compartment clean.
Excess oil and oily rags can catch fire. Dirt and
gear stowed in the compartment can restrict
cooling air.
S Make sure all fasteners are secure and torqued
properly.
S Do not work on the genset when mentally or
physically fatigued or after consuming alcohol
or drugs.
S You must be trained and experienced to make
adjustments while the genset is running—hot,
moving or electrically live parts can cause se-
vere personal injury or death.
S Used engine oil has been identified by some
state and federal agencies as causing cancer
or reproductive toxicity. Do not ingest, inhale, or
contact used oil or its vapors.
S Benzene and lead in some gasolines have
been identified by some state and federal
agencies as causing cancer or reproductive
toxicity. Do not to ingest, inhale or contact gaso-
line or its vapors.
S Keep multi-class ABC fire extinguishers handy.
Class A fires involve ordinary combustible ma-
terials such as wood and cloth; Class B fires,
combustible and flammable liquid fuels and
gaseous fuels; Class C fires, live electrical
equipment. (ref. NFPA No. 10)
S Genset installation and operation must comply
with all applicable local, state and federal codes
and regulations.
GENERATOR VOLTAGE IS DEADLY!
S Disable the automatic genset starting feature of
an inverter-charger or other automatic starting
device before servicing the genset.
S Generator electrical output connections must
be made by a trained and experienced electri-
cian in accordance with applicable codes.
S The genset must not be connected to shore
power or to any other source of electrical pow-
er. Back-feed to shore power can cause electric
shock resulting in severe personal injury or
death and damage to equipment. An approved
switching device must be used to prevent inter-
connections.
S Use caution when working on live electrical
equipment. Remove jewelry, make sure cloth-
ing and shoes are dry, stand on a dry wooden
platform or rubber insulating mat and use tools
with insulated handles.
iv
ENGINE EXHAUST IS DEADLY!
S Inspect for exhaust leaks at every startup and
after every eight hours of running.
S Learn the symptoms of carbon monoxide poi-
soning in this manual.
S Never sleep in the vehicle while the genset is
running unless the vehicle is equipped with a
working carbon monoxide detector.
S Make sure there is ample fresh air when operat-
ing the genset in a confined area.
S Disable the automatic genset starting feature of
an inverter-charger or other automatic starting
device before storing the vehicle or parking it in
a garage or other confined space.
S The exhaust system must be installed in accor-
dance with the genset Installation Manual.
S Engine cooling air must not be used for heating
the working or living space or compartment.
FUEL IS FLAMMABLE AND EXPLOSIVE
S Do not smoke or turn electrical switches ON or
OFF where fuel fumes are present or in areas
sharing ventilation with fuel tanks or equip-
ment. Keep flame, sparks, pilot lights, arc-pro-
ducing equipment and switches and all other
sources of ignition well away.
S Fuel lines must be secured, free of leaks and
separated or shielded from electrical wiring.
S Leaks can lead to explosive accumulations of
gas. Natural gas rises when released and can
accumulate under hoods and inside housings
and buildings. LPG sinks when released and
can accumulate inside housings and base-
ments and other below-grade spaces. Prevent
leaks and the accumulation of gas.
BATTERY GAS IS EXPLOSIVE
S Wear safety glasses.
S Do not smoke.
S To reduce arcing when disconnecting or recon-
necting battery cables, always disconnect the
negative (−) battery cable first and reconnect it
last.
MOVING PARTS CAN CAUSE SEVERE
PERSONAL INJURY OR DEATH
S Disable the automatic genset starting feature of
an inverter-charger or other automatic starting
device before servicing the genset.
S Do not wear loose clothing or jewelry near mov-
ing parts such as PTO shafts, fans, belts and
pulleys.
S Keep hands away from moving parts.
S Keep guards in place over fans, belts, pulleys,
and other moving parts.

1. Introduction
This is the service manual for the KV, KVC, KVD se-
ries of generator sets (gensets). Read and carefully
observe all of the instructions and safety precau-
tions in this manual.
WARNING Improper service or parts replace-
ment can lead to severe personal injury or death
and to damage to equipment and property. Ser-
vice personnel must be qualified to perform
electrical and mechanical service.
WARNING Unauthorized modifications or re-
placement of fuel, exhaust, air intake or speed
control system components that affect engine
emissions are prohibited by law in the State of
California.
WARNING LPG (liquified petroleum gas) is
flammable and explosive and can cause as-
phyxiation. NFPA 58, Section 1.6 requires all
persons handling LPG to be trained in proper
handling and operating procedures.
See the Operator’s Manual for instructions concern-
ing operation, maintenance and storage and for rec-
ommendations concerning engine lubricating oil
and fuel.
See the Installation Manual for important recom-
mendations concerning the installation and for a list
of the installation codes and standards for safety
which may be applicable.
See the Parts Manual for parts identification num-
bers and required quantities and for exploded views
of the genset subassemblies. Genuine Onan® re-
placement parts are recommended for best results.
When contacting Onan for parts or product informa-
tion, be ready to provide the model and serial num-
bers on the genset nameplate. Figure 1-1 illustrates
the nameplate and its location. Every character in
these numbers is significant. (The last character of
the model number is the specification letter, which is
important for obtaining the right parts.)
