OPERATION
Never stop the engine from full load except in case of emer-
gency.
Before shutting down run the engine 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 (9).
Additional emergency shut-down switches are located on the
power house. For more information → See "MACHINERY
HOUSE" on page 140.
Stopping procedure, see illustration Z25484.
1. Park the Shovel at a safe place on level and solid ground.
For more information → See "PARKING THE SHOVEL"
on page 200.
2. Deposit the working attachment onto the ground, proceed as
follows:
A - Backhoe Attachment
Lower the backhoe attachment fully extended onto the
ground in a position as shown on the oil level plate at the
hydraulic oil reservoir, see page 169 for more information.
B - Bottom Dump Bucket Attachment
Lower the bottom dump bucket attachment onto the
ground in a position as shown on the oil level plate at the
hydraulic oil reservoir, i.e. the stick cylinders are fully
retracted and the bucket is fully rolled back so that the
bucket back wall contacts the stick.
The positions A or B are necessary to prevent unintentional
movement of the working attachment when the pressure in
the hydraulic system is relieved and for correct checking pro-
cedure of the hydraulic oil level.
3. Move all controls into neutral position.
4. Set toggle switch (4) to low idle speed position. Let the engine
idle for about five minutes without load.
5. Turn switches (8) clockwise to stop position. After the engine
has come to standstill, relieve the pressure in the hydraulic
system.
