3. Periodic Maintenance
Periodic maintenance is essential for top perfor-
mance and long genset life. Use Table 3-1 as a
guide for normal periodic maintenance. In hot and
dusty environments some maintenance procedures
should be performed more frequently, as indicated
by the footnotes in the table.
Maintenance, replacement or repair of emission
control devices and systems may be performed by
any engine repair establishment or individual. How-
ever, warranty work must be completed by an au-
thorized Cummins Onan dealer.
WARNING
Accidental or remote starting can
cause severe personal injury or death. Discon-
nect the negative (−) cable at the battery to pre-
vent starting while working on the genset.
