OPERATION 3.15 STOPPING THE ENGINES With the engines at standstill and main switch (1) in ON posi- tion, move all controls for working attachment and crawlers several times through all shift positions to relieve the pres- sure in the hydraulic system. The necessary oil pressure for shifting the spools of the main control valves is provided by a pressure accumulator in the pilot oil circuit. NOTICE The pressure accumulator in the pilot oil circuit serves also for lowering a raised working attachment to the ground with the engines at standstill.
If, for example, the engines stall with the working attachment in a raised position, lowering of the working attachment is possible by operating the respec- tive control lever. 6. Set main switch key (1) to ”0” position and remove. 7. Switch off the battery main switches and remove keys. 243 WARNING
