CONTROLS AND FEATURES
Periodic maintenance is required
when either the operating hours or the
time since last maintenance reaches
the prescribed limit. Therefore,
periodic maintenance may be
required based on the number of
months since the last maintenance
before the alert based on engine
operating hours displays (see
MAINTENANCE SCHEDULE
on
page 91).
Reset the hour counter whenever
maintenance is performed, whether
based on the time interval or the
number of operating hours.
