In case of emergency, push the emergency but-
ton EB: the MEWP engine switches off and all oper-
ations are disabled. This button has priority over all
other commands.
The emergency button has a mechanical locking de-
vice, therefore, to restore normal working conditions,
it must be unlocked by turning it clockwise.
On the machine, there are emergency buttons in the
following positions:
• on the radio control station (Picture 8);
• on the basket remote control (Picture 12);
• on the left side of outriggers control station
(Picture 13).
In order to secure the machine, perform the following
procedures in the chronological order indicated:
1. recovery of the aerial part;
2. closing of the stabilizers;
3. retraction (*optional) and travel of the
tracks.
4.6.2 Emergency bypass
In case the basket operator pressed the emergency
button and were unable to reset this button at the
original position (due to blackout, fainting or other), it
will be possible to disable that safety function through
the “emergency bypass” (Picture 4) covered by a
yellow cap and located on the switching on/off box.
The ground operator removes a safety lead seal and
disable the emergency through an internal on/off
lever.
It will be care and responsibility of the opera-
tors, at the end of the operations, to reset the
original conditions, including the resealing
with seal compulsorily branded “CMC”.
4.6.3 Failure of hydraulic system
In case of emergency (fuel run out and/or breakage
of a hydraulic component, endothermic power failure,
etc.), to obtain pressure inside the hydraulic circuit,
necessary to the movement of the MEWP’s compo-
nents, you can use the auxiliary electric engine (*op-
tional) or the electropump (*optional), if installed, ac-
tivating it as described in paragraph 4.5.6.
Once they are started, carry out the recovery opera-
tions through the emergency control station (Picture
15).
In case of their absence, the manual pump can be
used for emergency recovery of the MEWP.
