The raised working attachment can also be lowered with the
ENGINE at standstill. If, for example, the engine stalls with
the working attachment in a raised position, lowering of the
working attachment is possible by moving control lever (2) to
position (A). The necessary oil pressure for shifting the
spools of the main control valves is provided by a pressure
accumulator in the pilot oil circuit. After stopping the engine,
relieve the pressure in the hydraulic system.
