Depressurising the hydraulic circuits for
the "5th hydraulic function"
If the truck has a "5th hydraulic function", the
hydraulic circuit of this function must also be
depressurised. The procedure is similar to the
depressurisation of the hydraulic circuits for
the basic functions and the additional func-
tions. In addition, the hydraulic circuit is dep-
ressurised in the same way as the attach-
ments are operated. The hydraulic circuit for
the "5th hydraulic function" is actuated using
the function key for the "5th function" (2).
– Actuate the function key for the "5th func-
tion" (2).
The LED for the "5th function"
lights up.
– Push the operating lever (1) once in the di-
rection of the arrow until the end position is
reached.
The hydraulic circuit of the 5th hydraulic func-
tion is depressurised. The plug connectors on
the lift mast are depressurised.
– Actuate the function key for the "5th func-
tion" (2).
The LED for the "5th function"
goes out.
Completing the depressurisation
– To complete the depressurisation, observe
the section entitled "Exiting the wizard".

tem using a quadruple mini-lever
– Start the "wizard for depressurising the hy-
draulic system".
