Overload Warning System (If fitted)
The overload warning system senses the pressure in the
boom raise pressure circuit, and gives an audible warning
when the pressure exceeds the predetermined limits and
there is a risk that the machine could become unstable.
When the machine is used for lifting, the system must be
switched ON. To operate the system push the overload
warning switch A. When the system is active the lamp in
the switch is illuminated. K
Fig 46. ( T 96).
If the safe operating lift limit is exceeded the buzzer will
sound. When the buzzer sounds, the operator must do the
necessary corrective action to reduce the lift. When this is
fulfilled, the buzzer is cancelled and the system resets
automatically.
When the machine is not used for object handling the
system must be switched OFF, (the overload warning
switch is not illuminated) otherwise the buzzer will sound
during digging operations.

When the overload protection system buzzer sounds,
you must decrease the machine lift. If you do not
decrease the machine lift a stability hazard could
occur. When the machine is in a safe position the
