After Starting Engine
• Allow the engine to idle for 3 to 5 minutes, or allow
the engine to idle until the water temperature
indicator begins to rise. Check all gauges during
the warm-up period.
Constant speed engines should be allowed to
operate at low idle for 3 minutes before used at
operational speed. If the low idle option is not
available, then operate the engine at operational
speed with no load for 2 minutes.
Note: Gauge readings should be observed and the
data should be recorded frequently while the engine
is operating. Comparing the data over time will help
to determine normal readings for each gauge.
Comparing data over time will also help detect
abnormal operating developments. Significant
changes in the readings should be investigated.
