Safety information about the safe load indicator and
overload protection
Functional check of safe load indicator: As soon as the
starter of the machine is switched on (starting key in
position 1), all the LEDs in the safe load indicator
illuminate briefly and a signal sounds. The safe load
indicator is malfunctioning if this is not the case, or if the
LEDs illuminate continuously or the signal sounds
continuously. Do not work with the machine in this case.
The safe load indicator must be checked and adjusted or
repaired by qualified personnel.
All repair and adjustment work on the safe load indicator
and overload protection may only be performed by
authorized personnel.
Information
The safe load indicator only gives a warning in the event
of insufficient stability in the longitudinal direction. Lateral
loads are not indicated by the safe load indicator.
