1.
Verify power to the load can be interrupted. Warn
any equipment users that there will be a temporary
power disruption.

Perform the necessary maintenance (based on the
hourly requirements).

When the generator is running, and all engine and
generator parameters (voltage, frequency, coolant
temp, oil pressure, etc.) have been verified as
correct, close the Main Circuit Breaker (MCB).

Make a final visual inspection of the generator to
verify proper operation.
Maintenance
Regular maintenance will improve performance and
extend engine/equipment life. Generac Mobile Products,
LLC. recommends that all maintenance work be
performed by a Generac Mobile Products Authorized
Service Dealer (GMP ASD). Regular maintenance,
replacement or repair of the emissions control devices
and systems may be performed by any repair shop or
person of the owner’s choosing. However, to obtain
emissions control warranty service free of charge, the
work must be performed by a GMP ASD. See the
emissions warranty.
NOTE:
Normal maintenance service and replacement of
parts is the responsibility of the owner and, as such, are
not considered defects in materials or workmanship
within the terms of the warranty. It is strongly recom-
mended that equipment be periodically checked by a
GMP ASD.
Daily checks must be performed when unit is operated
continuously for extended periods of time. Daily checks
and routine monthly checks can be performed by a GMP
ASD.
