OPERATION
REMARK
Never operate the starter longer than 30 seconds at a time in
order to avoid damage. If the engine does not start within the first
30 seconds, wait 2 minutes before cranking again.
8. As soon as the engines are running, check display (3) for
messages.
After starting observe the following:
The ECS System monitors the Shovel's functions and provides
information about the appropriate operational data.
If a FAULT message is displayed on screen (3), the acoustic
warning signal (2) will sound simultaneously for approximately 1
second. In such a case proceed according to the instructions of
the ECS system on page 92.
Warning buzzer (2) will sound continuously when the hydraulic oil
level is too low. In this case, stop the engines, locate and correct
the cause immediately. Fill up hydraulic oil to the correct level.
9. Idle the engines 3 to 5 minutes to attain a minimum coolant
temperature of 60°C before operating with a load.
10. After warming up of the engines, the speed can be increased
by setting switch (4) to high idle speed position.
NOTICE
DO NOT idle the engines for excessively long periods. Long
periods of idling, more than 10 minutes, can damage the
engine because combustion chamber temperature drop so
low the fuel will not burn completely. This will cause carbon
to clog the injector spray holes and piston rings and can
cause the valves to stick.
REMARK
If one engine fails to work during operation, the shovel can be
operated with the second engine as an emergency measure, e.g.
for moving the shovel out of a danger area.
Automatic Engine Shut-Down System (Safety Chain)
The engine(s) will be stopped or shifted to low idle speed auto-
matically if a serious trouble condition occurs. The operator will be
informed about the trouble condition by a corresponding message
displayed on screen (3).
Never let the engines run with disconnected batteries. This
may cause alternator damage.
