CMC S19N - 4.7.6 At the end of the works

➔ Be careful when working in close buildings: due to the “wind tunnel”
effect, sudden blasts could cause swinging, thus impairing the ma-
chine stability;
It is forbidden to lift “full surface” panels (signs, advertising panels,
boards, etc.): these could cause the “sail” effect;
It is forbidden to leave the MEWP unattended when it is in working
position;
It is forbidden to exceed the max number of basket operators al-
lowed;
During the normal use of the platform, it is absolutely forbidden to
use electronic instruments which do not meet the requirements of
the directive 72/245/CE and its following amendments: the additional
electronic instruments could impair good functioning of the platform
electronic components.

➔ Before moving the machine, check that the MEWP aerial part is set in
the transport position: check that the pantograph is on its own support,
that the telescopic boom is withdrawn and rests on its own support;
➔ Before moving the machine, check that all the outriggers are complete-
ly withdrawn and blocked, that they are set in the transport position,
with the plates completely lifted.
➔ Park the MEWP in the storage location.
4.8 Safety devices    
A - Electrical devices
▪ Removable key for the MEWP engine ignition.
▪ Emergency stop buttons on control stations.
▪ Emergency stop buttons on the control stations.
▪ Basket levelling maneuver only allowed when the MEWP aerial part is
in rest position (telescopic boom on its support).
▪ Microswitch blocking the outriggers controls with booms lifted and if the
extension is not in withdrawn position;
▪ Microswitch for outriggers end-of-stroke;
▪ Protection fuses against brownout, both on the power circuit and on the
control circuit;
▪ All machine controls hold-to-run;
▪ Interlock stabilizers-boom maneuver:
- block of the maneuvers of the MEWP aerial part when this is not
stabilized;
- block of the maneuvers of stabilizers return/extraction when the
MEWP aerial part is not in rest position.
▪ Block for the extraction and the lowering of the telescopic boom to the
achievement of the limit switch.
▪ Consent light for machine stabilization.
▪ Warning light for electrical supply of the MEWP.
▪ Moment limiter device.
