least FORWARD stability is shown in Figure 4-1., and its position
of least BACKWARD stability is shown in Figure 4-2.

4.3 CAPACITY SELECT
The Boom Control System allows the operator to select
operation in a 500 lb. (227 kg for ANSI markets and 230
kg for CE and Australia markets) capacity restriction
envelope or a 1000 lb. (454 kg for ANSI markets and 450
kg for CE and Australia markets) capacity restriction
envelope. The operator selects the desired capacity
restriction by positioning the Capacity Select switch on
the platform console. The Capacity Indicator shows the capacity
selected, and both capacity lights will flash and an alarm sound if the
platform is out of the selected capacity range.
NOTE: Operation in the 1000 lb. (454 kg for ANSI markets and 450 kg for
CE and Australia markets) envelope requires the jib to be fully
retracted.
