Section 3: Operation

Overview

The engine can be started in low-idle or at normal
operating speed (1,800 rpm). In cold weather, it is
recommended to start the engine in low-idle condition,
and idle for up to one minute. That allows the engine oil
to heat up before increasing engine speed and applying
load. If the engine is in an idle condition for an extended
period, the ETM may drive a higher engine speed to
generate more heat and activate a regeneration.
IMPORTANT NOTE: The breaker cannot be closed
while engine is in low-idle condition, as such load
cannot be applied.
Low idle speed is 1,100 rpm.

Prestart Checklist

All items in the prestart checklist must be completed
before starting the unit. This checklist applies to both
manual and remote starting of the unit.

Cold Weather Operation

In cold environments, units equipped with starting aids
are recommended. See
Equipped).
When starting a unit equipped with starting aids, observe
these guidelines:
Follow supplier instructions for starting aids
provided on engine.
An optional 24 VDC, 30 A battery charger can be
configured with the machine if needed and is
recommended if machine is equipped with fuel
filter heater or CCV heater. The shore power inlet
receptacle (120 V, 15 A [5-15P]) can be located on
the convenience receptacle panel. Shore power
will be required to utilize on-board battery charger.
When engine has started, the inlet receptacle can
be disconnected as charger will no longer be
needed if engine continues to run.
IMPORTANT NOTE: In cold temperatures, with the
engine off, the DC-powered heaters for cold starting
and cold-operation will deplete the engine-starting
batteries if the batteries are not being charged by the
optional on board battery charger.
NOTE: If alternate battery charger is being used please
see
Using An External Battery Charger
charger connection.
An optional coolant heater and oil pan heater can
be configured to aide cold weather starting. The
shore power inlet receptacle (125 V, 30 A) can be
located on the convenience receptacle panel.
Shore power will be required to utilize on-board
coolant and oil pan heater. If machine has been
stored at -40F (-40C) temperatures for 8 hours
more, preheat times up to 6 hours might be
required to provide adequate heating to coolant
