2.5 Manual pump
The manual pump conveys the pressured oil, to make manoeuvres in case of emergency due to
failures of the main hydraulic system.
The manual pump is equipped with a manual deviator that allows choosing to
move
either
the two
right outriggers (Position 1) or the two left outriggers and the aerial part of the structure (Position
2).
The outrigger operations are allowed only if the electric system hasn’t got failures and the ignition
key is in the ON position.
In case of failure of the electric system, if you need to move the outriggers you have to move the
deviator aerial part-undercarriage part manually, using the mechanical commutator that is delivered
together with the machine in the electric components’ housing (see picture).
