Control of the external hydraulic circuit front outlets
The front outlets of the external hydraulic circuit are
controlled by a lever (a) which has four positions:
N - Neutral position. Quick coupler drives (1) and (2) are
closed and oil in the hydraulic appliance connected is
blocked. Lever (a) is locked in this position
1 - Pressure in quick coupler (1). Quick coupler (2) is
connected with the drain. Lever (a) is locked in this
position. In case pressure exceeds 16.5 MPa when
connected to quick coupler (1), lever (a) automatically
returns to (N) position - 'kick-out' function.
2 - Pressure in quick coupler (2). Quick coupler (1) is
connected with the drain. Lever (a) is locked in this
position. In case pressure exceeds 16.5 MPa when
connected to quick coupler (2), lever (a) automatically
returns to (N) position - 'kick-out' function
P - Floating position. Both quick couplers (1) and (2) are
connected with the drain and oil is free to flow in both
directions. Lever (a) is locked in this position.
