Hour Meter
The Hour Meter tracks hours of operation for
scheduled maintenance. See Figure 2-6.
• The CHG OIL display will illuminate every
100 hours. The message will flash one hour
before and one hour after each 100 hour
interval, providing a two hour window to
perform service.
• The SVC display will illuminate every 100
hours. The message will flash one hour
before and one hour after each 200 hour
interval providing a two hour window to per-
form service.
When the hour meter is in flash alert mode,
the maintenance message will alternate with
elapsed time in hours and tenths. The hours
will flash four times, then alternate with the
maintenance message four times until the
meter automatically resets.
• 100 hours - CHG OIL — Oil Change Inter-
val (Every 100 hrs)
• 200 hours - SVC — Service Air Filter
(Every 200 hrs)
NOTE: The hour glass icon will flash when the
engine is running. This signifies the meter is
recording hours of operation.
