After Starting Engine
After Starting Engine
After starting, the engine may be held at low speed
for up to 30 seconds to allow engine systems to
stabilize. The duration will depend on ambient
temperature, time since last run and other factors.
After starting the engine and allowing the engine to
stabilize, increase the engine speed to 1500 RPM for
10 seconds to ensure that the alternator begins to
charge the battery.
Note: In ambient temperatures from 0° to 48°C
(0° to 86.4°F), the warm-up time is approximately 3
minutes. In temperatures below 0°C (32°F),
additional warm-up time may be required.
When the engine idles during warm-up, observe the
following conditions:
Do not check the high-pressure fuel lines with the
engine or the starting motor in operation. If you
inspect the engine in operation, always use the
proper inspection procedure to avoid a fluid
penetration hazard. Refer to Operation and
Maintenance Manual, "General Hazard Information"
for more information.
• Check for fluid and air leaks at idle rpm, and at
one-half full rpm (no load on the engine) before
operating the engine under load. This check may
not be possible in some applications.
• 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 whilst 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.
