Emergency operations
Before starting the emergency procedures, it could be useful to
contact C.M.C. Service and communicate errors/problems.
4.6.1
Emergency button
In case of emergency, push the emergency buttons:
o on the centre of the control station in the basket (Picture 9);
o on the centre of the wired remote control (Picture 5);
o on the centre of the switching on/off box (Picture 4).
Pushing this button (with mechanical retention), the endothermic or electric*
engine of the MEWP is turned off and all manoeuvres are disabled. To re-
store normal operating conditions, this button must be turned clockwise.
To secure the machine, perform the following procedures in the chronologi-
cal order indicated:
1. recovery of the aerial part;
2. closing of the stabilizers;
3. travel of the tracks.
4.6.2
Emergency bypass
In case the operator in the basket has pushed the emergency button and is
unable to reset it to its original position (due to fainting or other), it will be
possible to disable that safety function through the yellow lever 3
“EMERGENCY BYPASS” below the machine switching on/off box (Picture
4).
The ground operator has to remove the lead safety seal and disable the
emergency through an internal ON/OFF lever:
It will be care and responsibility of the operators, at the end of the
operations, to reset the original conditions, including the resealing
with seal compulsorily branded “C.M.C.”.
4.6.3
Failure of hydraulic system
In case of emergency (exhaustion of batteries charge, electric power failure,
etc..), to obtain pressure inside the hydraulic circuit, necessary to the move-
ment of the MEWP’s components, you can use the electropump (*optional),
if installed, activating it as described in paragraph 4.5.6.
Once the electropump has started, carry out the recovery operations of the
aerial part through the emergency control station (Picture 11).
In case of absence of the electropump, the manual pump can be used for
emergency recovery of the MEWP.
4.6.4
Failure of electric system
In case of electrical system failure, to obtain pressure inside the hydraulic
circuit and to perform emergency recovery of the MEWP, it is necessary the
presence of two operators and the use of manual pump.
4.6.5
MEWP recovery in case of simultaneous hydraulic
and electric failure (use of manual pump)
In case of emergency (hydraulic system failure if not available electropump,
or simultaneous failure of the hydraulic and electrical system), to obtain the
pressure inside the hydraulic circuit, you can use the manual pump.
The manual pump lever must be inserted in the appropriate position shown
in Picture 18, between the emergency control station and the machine
switching on/off station.
