CAUTION
Welding the generator set.
Can cause severe
equipment damage.
Never weld components of the
generator set without
disconnecting the battery, controller
wiring harness, and engine electronic
control module (ECM).

Hazardous voltage can
severe injury or death. Electrocution
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
electrical leads or appliances when
standing in water or on wet ground
because these conditions increase the
risk of electrocution.
Disconnecting the electrical load.
Hazardous voltage can
severe injury or death. Disconnect
the generator set from the load by
opening 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.

performing voltage tests. Observe the
following precautions when performing
voltage tests: (1) Remove all jewelry.

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

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
