4.6.5 Emergency procedure in case of
electrical and hydraulic system (manual
pump)
In the unlikely case of concurrent electrical and hydraulic
failure (engine malfunction and absence of electropump,
electropump failure, etc.), it will be necessary to send oil
to the circuit through the manual pump, inserting it into
the appropriate attack on the frame (Picture 60).
Picture 60: frame insert for manual pump handle.
• Before starting the recovery of the aerial part, turn
the double tap on to the right, on the "aerial part"
symbol indicated by the decal applied near
the same tap.
Then, move to the right side of the frame where
the single tap of the manual pump is positioned
(Picture 61- this tap directs the oil in the hydraulic
circuit towards the aerial part or the part of the
circuit which performs the leveling of the basket).
Move it to the left to operate the aerial part
recovery or to the right to perform the leveling of
the basket.
• Before starting the recovery of the outriggers,
however, just move the double tap (Picture 61) to
the left, on the "outriggers" symbol indicated
by the appropriate decal applied.
Picture 61: manual pump tap.
Then carry out the emergency operations described in
paragraph 4.6.3.
