Excessive Idling; Changing The Idle Speed; Shutting Down The Engine; Shutting Down After Hard Operation - Detroit Diesel EPA04 MBE 900 Operator's Manual

OPERATION

Excessive Idling

Never allow the engine to idle for
more than 30 minutes. Excessive
idling can cause oil to leak from the
turbocharger.

Changing the Idle Speed

The rpm range of the MBE900
engine is 600 rpm to 850 rpm if the
parameters in the DDEC-VCU are set
to the default range.
Change the idling speed as follows:
1. Turn the cruise control switch to
the OFF position.
2. To increase the idle speed, push
the "Resume" switch until the idle
is fast enough.
3. To decrease the idle speed, push
the "Decel" switch until the idle
is slow enough.

Shutting Down the Engine

If the engine has been running at full
output or the coolant temperature has
been high, allow the engine to idle
for one to two minutes without load.
Then turn off the ignition key switch.
If any the following occur, shut down
the engine immediately.
□ The oil pressure swings back and
forth or falls sharply.

□ Engine power and rpm fall, even
though the accelerator pedal
remains steady.
□ The exhaust pipe gives off heavy
smoke.
□ The coolant and/or oil temperature
climb abnormally.
□ Abnormal sounds suddenly occur
in the engine or turbocharger.
Shutting Down After Hard
Operation
After hard operation, if the engine
has been running at full output or the
coolant temperature has been high,
allow the engine to idle for one to
two minutes without load. Shutting
down the engine without idling may
cause damage to the turbocharger.
Turn off the ignition switch and shut
down the engine.
