Section 4: Maintenance
Maintenance
Regular maintenance will improve performance and
extend engine/equipment life. Generac Mobile recom-
mends that all maintenance work be performed by a
GMASD. Regular maintenance, replacement, or repair of
the emissions control devices and systems may be per-
formed by any repair shop or person of the owner's
choosing. To obtain emissions control warranty service
free of charge, the work must be performed by a
GMASD. See the emissions warranty.
Maintenance Tasks
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 an
authorized operator.
NOTE: Normal maintenance, service, and replacement
of parts are the responsibility of the owner and are not
considered defects in materials or workmanship within
the terms of the warranty. It is strongly recommended
that equipment be periodically checked by a GMASD.
Daily Walk Around Inspection
Inspect for conditions that could hinder performance or
safety, such as (but not limited to) oil, coolant, and fuel
leakage, blocked vents, loose or missing hardware, and
improper electrical connections. Check for foreign matter
blocking vents and on top of unit. Perform any necessary
maintenance tasks. See
