Grounding electrical equipment.
Hazardous voltage can

is possible whenever electricity is
present. Open the main circuit
breakers of all power sources before
servicing the equipment. Configure the
installation to electrically ground the
generator set, transfer switch, and
related equipment and
circuits to comply with applicable codes
and standards. Never

standing in water or on wet ground
because these conditions increase the
risk of electrocution.
Welding the generator set.
cause severe electrical equipment
damage. Before welding the generator
set perform the following steps:
(1) Remove the battery
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.

Remove all jewelry before servicing the
equipment.
Testing the voltage
Hazardous voltage can

is present at the voltage regulator heat
sink. To prevent electrical shock do not
touch the voltage regulator heat sink
when testing the voltage regulator.

death. The engine block heater can
cause electrical shock. Remove the
engine block heater plug from the
electrical outlet before working on the
block heater electrical connections.

Hot Parts
WARNING
Hot coolant and steam.
Can cause severe injury or death.
Before removing the pressure cap,
stop the generator set and allow it to
cool. Then loosen the pressure cap
to relieve pressure.
WARNING
Hot engine and exhaust system.
Can cause severe injury or death.
Do not work on the generator set until
it cools.
Checking the coolant level.

death. Allow the engine to cool.
Release pressure from the cooling
system before removing the pressure
cap. To release pressure, cover the
pressure cap with a thick cloth and then
slowly turn the cap counterclockwise to
the first stop. Remove the cap after
pressure has been
released and the engine has cooled.
Check the coolant level at the tank if the
generator set has a coolant recovery
tank.
