Platform Load Sensing System (LSS)
The Platform Load Sensing System provides the platform capac
-
ity 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 positions which are called FOR
-
WARD and BACKWARD stability. The machines position of least
FORWARD stability is shown in Figure 4-2., Position of Least For
ward Stability, and its position of least BACKWARD stability is
shown in Figure 4-1., Position of Least Backward Stability.
TO AVOID FORWARD OR BACKWARD TIPPING, DO NOT OVERLOAD MACHINE OR OPER
