Explosive fuel vapors can cause
severe injury or death.
additional precautions when using the
following fuels:
Propane (LPG)—Adequate ventilation
is mandatory. Because propane is
heavier than air, install propane gas
detectors low in a room. Inspect the
detectors per the manufacturer's
instructions.
Natural Gas—Adequate ventilation is
mandatory. Because natural gas rises,
install natural gas detectors high in a
room. Inspect the detectors per the
manufacturer's instructions.
Gas fuel leaks. Explosive fuel
vapors can cause severe injury or
death. Fuel leakage can cause an
explosion. Check the LPG vapor 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
(10- 14 inches water column). Do not
use a soap solution containing either
ammonia or chlorine because both
prevent bubble formation. A successful
test depends on the ability of the
solution to bubble.
Hazardous Noise
CAUTION
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.

and electrical circuits. Turn off the main
circuit breakers of all power sources
before servicing the equipment. Never
contact electrical leads or appliances

Disconnecting the electrical load.
Hazardous voltage will cause severe
injury or death. Disconnect the
generator set from the load by turning
off the line circuit breaker or by
disconnecting the generator set output
leads from the transfer switch and
heavily taping the ends of the leads.
High voltage transferred to the load
during testing may cause personal
injury and equipment damage. Do not
use the safeguard circuit breaker in
place of the line circuit breaker. The
safeguard circuit breaker does not
disconnect the generator set from the
load.
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 battery-
charging alternator connections.
(5) Attach the weld ground connection
close to the weld location.
Connecting the battery and the
battery charger. Hazardous voltage
will cause severe injury or death.
Reconnect the battery
positive to positive and negative to
negative, to avoid electrical shock and
damage to the battery charger and
battery(ies). Have a
electrician install the battery(ies).
