The fuel system. Explosive fuel
vapors can cause severe injury or
death. Vaporized fuels are highly
explosive. Use extreme care when
handling and storing fuels. Store fuels
in a well-ventilated area away from
spark-producing equipment and out of
the reach of children. Never add fuel
to the tank while the engine is running
because spilled fuel may ignite on
contact with hot parts or from sparks.
Do not smoke or permit flames or
sparks to occur near sources of spilled
fuel or fuel vapors. Keep the fuel lines
and connections tight and in good
condition. Do not replace flexible fuel
lines with rigid lines. Use flexible
sections to avoid fuel line breakage
caused by vibration. Do not operate
the generator set in the presence of
fuel leaks, fuel accumulation, or
sparks. Repair fuel systems before
resuming generator set operation.
Gas fuel leaks. Explosive fuel
vapors can cause severe injury or
death. Fuel leakage can cause an
explosion. Check the LP vapor gas or
natural gas fuel system for leakage
by using a soap and water solution
with the fuel system test pressurized
to 6–8 ounces per square inch (10–14
inches water column). Do not use a
soap solution containing
ammonia or chlorine because both
prevent bubble formation.
successful test depends on the ability
of the solution to bubble.

Hazardous Noise
!
Hazardous noise.
Can cause hearing loss.
Never operate the generator set
without a muffler or with a faulty
exhaust system.
Engine noise. Hazardous noise can
cause hearing loss. Generator sets
not equipped with sound enclosures
can produce noise levels greater than
105 dBA. Prolonged exposure to
noise levels greater than 85 dBA can
cause permanent hearing loss. Wear
hearing protection when near an
operating generator set.

Welding the generator set.
Can cause severe
equipment damage.
Never weld components of the
generator set without
disconnecting the battery, controller
wiring harness, and
electronic control module (ECM).
Grounding electrical
Hazardous voltage can
severe injury or death. Electrocution
is possible whenever electricity is
present. Ensure you comply with all
applicable codes and
Electrically ground the generator set
and related equipment and electrical
circuits. Turn off the main circuit
breakers of all power sources before
servicing the equipment.
contact electrical leads or appliances
when standing in water or on wet
ground because these
increase the risk of electrocution.
Welding on the generator set. Can
cause severe electrical equipment
damage. Before welding on the
generator set perform the following
steps: (1) Remove the battery cables,
negative (–) lead first. (2) Disconnect
all engine electronic control module
(ECM) connectors. (3) Disconnect all
generator set controller and voltage
regulator circuit board connectors. (4)
Disconnect the engine
charging alternator connections.
Attach the weld ground connection
close to the weld location.
High voltage test.
voltage can cause severe injury or
death. Follow the instructions of the
test equipment manufacturer when
performing high-voltage tests on the
rotor or stator. An improper test
procedure can damage equipment or
lead to generator set failure.
Servicing the generator set when it
is operating. Exposed moving
parts can cause severe injury or
death. Keep hands, feet, hair,
clothing, and test leads away from the
belts and pulleys when the generator
set is running. Replace guards,
screens, and covers before operating
the generator set.
