Section 3
Scheduled Maintenance
3-l. GENERAL
Scheduled maintenance is “preventive” maintenance.
Major repair can be avoided by correcting problems when
they are small. When performing maintenance, always
look for signs of potential trouble, such as loose connec-
tions or dirty components. When running the set, listen for
any unusual noises.
NOTE - Oil Change
3-2. SCHEDULED MAINTENANCE
Refer to Table 3-1 for scheduled maintenance requirements.
Perform each function at the indicated time interval. For
each function, refer to the applicable paragraph for instruc-
tions.
NOTE

five hours of operation, and thereafter on
K181QS and K341QS change oil every 25

every 50 hours.
For maintenance work on engine components,
refer to the Kohler engine service manual
