Do not operate controls swiftly and suddenly
It is forbidden to make the platform swing;
Check the MEWP stability during all the operations phases;
Do not move the MEWP during the working operations;
Keep enough safety distance from the obstacles: avoid contacts with
fixed (buildings, etc.) and moving (vehicles, cranes, etc.) objects, with
the truck cabin, with the outriggers and with other structure parts;
It is forbidden to use ladders or tables on the basket in order to in-
crease the MEWP outreach or working height;
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.
4.7.6
At the end of the works
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that the telescopic boom is withdrawn and rests on its own support;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ly withdrawn and blocked, that they are set in the transport position,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.
