Danger of falling.
–
Do not climb onto the boom or the attachments.
– Do not climb onto equipment parts (for example, boom
sections, ballast parts) hanging from a crane.
– Use secure climbing equipment when bolting the attach-
ments.
– Depending on the work height, use a ladder in accordance
with the applicable standards and regulations.
Risk of death from swinging fly boom.
The unsecured fly boom can swing out at high speed and
severely injure anybody in its swing range.
– Ensure that no one remains in the swing range except for
the operators.
– Check the bolting on the basic body is correct prior to
setup.
– Set the main boom in a horizontal position during the
setup process.
– Secure a rope, which can be used to fold down and guide
the tip by hand, to the head of the fly boom.
– Observe the prescribed sequence when setting the angle.
Folding in the fly boom requires sufficient space on the right-hand
side of the machine.
