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.
Hazardous Voltage/
Moving Parts
WARNING
Hazardous voltage. Moving parts.
Can cause severe injury or death.
Operate the generator set only when
all guards and electrical enclosures
are in place.
WARNING
Hazardous voltage.
Backfeed to the utility system can
cause property damage, severe
injury, or death.
If the generator set is used for
standby power, install an automatic
transfer switch to prevent inadvertent
interconnection of standby
normal sources of supply.

CAUTION
Welding the generator set.
Can cause
equipment damage.
Never weld components of the
generator set
disconnecting the battery, controller
wiring harness, and engine electronic
control module (ECM).
Grounding electrical equipment.
Hazardous voltage
severe injury or death. Electrocution
is possible whenever electricity is
present. Ensure you comply with all
applicable codes
Electrically ground the generator set,
transfer switch, and related equipment
and electrical circuits. Turn off the main
circuit breakers of all power sources
before servicing the equipment. Never
contact electrical leads or appliances
when standing in water or on wet
ground because these conditions
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 battery-
charging alternator
(5) Attach the weld ground connection
close to the weld location.
Connecting the battery and the
battery charger. Hazardous voltage
can cause severe injury or death.
Reconnect the

cause bodily injury and/or equipment
damage. Do not contact electrical
connections with tools or jewelry while
making adjustments or
Remove all jewelry before servicing the
equipment.
Electrical backfeed to the utility.
Hazardous backfeed voltage can
cause severe injury or death. Install
a transfer switch in standby power
installations to prevent the connection
of standby and other sources of power.
Electrical backfeed into
electrical system can cause severe
injury or death to utility personnel
working on power lines.
WARNING
Airborne particles.
Can cause severe
blindness.
Wear protective goggles and clothing
when using power tools, hand tools,
or compressed air.

WARNING
Unbalanced weight.
Improper lifting can cause severe
injury or death and equipment
damage.
Do not use lifting eyes.
