Platform Load Sensing System (LSS)
The Platform Load Sensing System provides the platform capacity to
the control system.
If the LSS system senses an overload condition, boom functions
will be disabled, the overload indicator is illuminated at both con
-
trol stations, and the overload alarm will sound. Reduce the
weight in the platform to not exceed the rated workload indi
-
cated on the capacity decal, then the controls will work again.
Stability
Machine stability is based on two (2) positions which are called
Forward and Backward stability. The machines position of least
Forward stability is shown in Figure 4-1., Position of Least For
-
ward Stability, and its position of least Backward stability is
shown in Figure 4-2., Position of Least Backward Stability.
TO AVOID FORWARD OR BACKWARD TIPPING, DO NOT OVERLOAD MACHINE OR OPER -
ATE THE MACHINE ON AN OUT-OF-LEVEL SURFACE.
