Periodic Maintenance
Periodic maintenance is essential for top perfor-
mance and long genset life. Use Table 3 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. Keeping a log of main-
tenance performed and hours run (Page 35) will
help you keep genset maintenance regular and pro-
vide a basis for supporting warranty claims.
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 Onan dealer.
