SECTION 4 - MACHINE OPERATION
4-4 – JLG Lift – 3121255
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 (See Figure
4-1.), and its position of least BACKWARD stability is shown
in (See Figure 4-2.)
TO AVOID FORWARD OR BACKWARD TIPPING, DO NOT OVERLOAD
MACHINE OR OPERATE THE MACHINE ON AN OUT-OF-LEVEL SUR-
FACE.
4.3 CAPACITY SELECT (1100SJP ONLY)
The Boom Control System allows the operator to select opera-
tion in a 500 pound (454 kg for ANSI markets and 450 kg for CE
and Australia markets) capacity restriction envelope or a 1000
pound (454 kg for ANSI markets and 450 kg for CE and Austra-
lia 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 capac-
ity range.
NOTE: Operation in the 1000 pound (454 kg for ANSI markets
and 450 kg for CE and Australia markets) envelope
requires the jib to be fixed in the centered position.
