Platform Load Sensing System (Lss); Stability - JLG 400S Operation And Safety Manual

SECTION 4 - MACHINE OPERATION

Platform Load Sensing System (LSS)

The Platform Load Sensing System provides the platform capacity to
the control system. The LSS will illuminate the appropriate capacity
zone on the capacity zone indicator.
If the LSS system senses an overload condition, boom functions will
be disabled, the overload indicator is illuminated at both control sta-
tions, and the overload alarm will sound. Reduce the weight in the
platform to not exceed the rated workload indicated on the capacity
decal, then the controls will work again.

Stability

Machine stability is based on two (2) conditions which are called
FORWARD and BACKWARD stability. The machine's position of
least FORWARD stability is shown in Figure 4-1., and its position
of least BACKWARD stability is shown in Figure 4-2.
TO AVOID FORWARD OR BACKWARD TIPPING, DO NOT OVERLOAD MACHINE OR OPER-
ATE THE MACHINE BEYOND THE LIMIT OF THE MAXIMUM OPERATING SLOPE.
