4.6.3 Hydraulic system failure
In case of emergency (fuel run out and/or breakage
of a hydraulic part), you can use the electric engine
(*optional) or the electropump (*optional), if in-
stalled.
If the electropump is started, carry out the recovery
operations through the emergency control station
(Picture 15).
In case of absence of this optional, the manual
pump can be used for emergency recovery of the
MEWP. Bring the manual pump handle and insert it
in the proper point of pumping (Picture 20).

emergency recovery of the MEWP, it is necessary
to activate the electropump (*optional) or, if it is not
installed, the presence of two operators and the use
of manual pump.
4.6.5 Simultaneous failure of hydraulic
and electrical system
In case of emergency (hydraulic system failure if not
available electropump, or simultaneous failure of the
hydraulic and electrical system), to obtain the pres-
sure inside the hydraulic circuit, you must use the
manual pump.
Recovery of the aerial part:
First carry out the recovery operations of
the basket, to make the operator on board
