4. Start-up
4.1 Safety informaon
Read the operang instrucons before
start-up of the magnet device!
A visual check is to be made before start-
up of the complete system!
Ensure that the generator is ghtened
rmly before start-up!
Check the correct t of the drive belts
before start-up!
Only aach load liing magnets to the
system! Operaon for other electrical
users is not permied!
Before beginning work on the enre
system disengage the drive motor!
Never open the terminal connecon box
and the 220 V connector on the generator
and the magnet while the motor is
running!

4.2 Safety regulaons magnet operaon
The operaon of a load liing magnet on a mobile
excavator represents a special mode of operaon and
an increased safety risk. In contrast to working with a
hydraulic grabber, the magnet picks up all available
ferromagnec material immediately aer it is switched
on.
This may even be more than the load-carrying capacity
of the mobile excavator allows.
Similarly, the magnet suddenly releases the lied
material aer it is switched o, if there is cable damage
or a short-circuit in the magnet feed cable. This can
lead to dangerous situaons in the working vicinity, for
example, if falling material causes other objects to be
hurled up by lever force. Furthermore, it is not excluded
that pieces of scrap iron may separate from the magnet
during a swiveling procedure, if these are located at
the lower end of the lied material cluster. For these
reasons, it is parcularly important to observe the
following principle:
While working with the load
liing magnet it is forbidden to
stand within the extended reach of
the excavator
Do not swivel the working equipment
or change the locaon of the
excavator with the magnets
switched on without a
payload - unintenonally
lied materials can lead to
human injury by lever force!
The magnet can oscillate strongly aer load release!
For this reason, the mechanically safe aachment of
the magnet in the form of a special magnet suspension
at the end of the arm on the mobile excavator is highly
recommended!
