OPERATION
Never stop the engines from full load except in case of emer-
gency.
Before shutting down run the engines at idling speed for
approximately 5 minutes. This cooling down period prevents
heat accumulation and thermal stress, especially in the tur-
bochargers.
For EMERGENCY SHUTDOWN of the Engine, use STRIKE
BUTTON (12).
Additional emergency shut-down switches are located on the
power house. For more information → See "POWER HOUSE"
on page 194.
Stopping procedure, see illustration Z 21758.
1. Park the Shovel at a safe place on level and solid ground.
For more information → See "PARKING THE SHOVEL"
on page 249.
2. Deposit the working attachment onto the ground, proceed as
follows:
A - Backhoe Attachment
Lower the backhoe attachment fully extended onto the
ground. The bucket opening must point to the ground.
B - Bottom Dump Bucket Attachment
Lower the bottom dump bucket attachment onto the
ground with the stick in a vertical position below the
boom-stick pivots. The bucket must rest completely flat
on the ground.
The positions A or B are necessary to prevent unintentional
movement of the working attachment when the pressure in
the hydraulic system is relieved.
3. Move all controls into neutral position.
4. Set toggle switch (4) to low idle speed position. Let the
engines idle for about five minutes without load.
5. Turn switches (7 and 10) clockwise to stop position. After the
engines have come to standstill, relieve the pressure in the
hydraulic system.
