OPERATION
Many occupational accidents
take place in abnormal
circumstances. Therefore it is
important to take into account
all the possible circumstances
that may arise during operation
of the machine.
Depending on the machine’s type, it will have
diverse safety devices and protectors. These are
meant to protect the machine and its operator,
and they must never be removed or altered.
Never start up or use the machine without all
the safety devices and protectors in place. Also
check the universal joint’s safety equipment and
joins.
Never insert any body part into the machine with
the engine running.
If any faults arise that may jeopardize occupational
safety, turn off the machine.
During operation, the machine’s operator is
responsible for safety in the whole work area.
Work may not be carried out in the presence of
any factors that jeopardize occupational safety.
Exercise extreme caution when hitching /
unhitching the machine from a tractor/trailer.
The machine’s operator must
have constant, unobstructed
visibility of the work area. If
this is not possible, the ope-
rator must work with an assis-
tant.
Look out for moving parts when the machine is
in operation.
Secure the machine against unauthorized and
accidental operation (e.g. moving when parked)
whenever it is left unattended.
Never leave the machine running unattended.
Avoid causing fast, stroke-like loading.
Never exceed the given operating values.
All safety and warning signs on and in the
machine must be legible and intact.
The machine may not be operated by persons
