Overload Warning System - Case WX145 Operator's Manual

S
WARNING
The overload warning system sends exclusively
acoustic and visual indication but thanks to them
the machine overturning is avoided.
When the warning system sounds:
- lower the load immediately,
- reduce the working radius or the load.
Hydraulic excavators used for lifting operations or
for transporting loads must be equipped with an
overload warning system and pipe break protections
in the lifting cylinders of the working equipment.
During these operations the overload warning sys-
tem must be activated.
When the admissible load moment is exceeded, the
red warning lamp (1) lights up. The buzzer sounds
at the same time. The display shows the "overload"
symbol (2) and the OVERLOAD text (3).
The admissible load moment is exceeded if too
heavy a load is to be lifted with the working radius of
the equipment being too great.
SETTING THE OVERLOAD WARNING SYSTEM
INTO OPERATION
The overload working system can be used option-
ally in two different operation modes:
Press button (1) once, the left lamp (2) lights up
when the machine is used as a crane, without stabi-
lizers.
Press button (1) twice, the right lamp (3) lights up
when the machine is used as a crane, with stabiliz-
ers (stabilizers/blade).
Before using the machine for lifting operations, acti-
vate the overload warning system:
With button (1) set the overload warning system to
required operation mode.
The button lamp lights up.
Check that the overload warning system works cor-
rectly.
