9.10 LOAD STABILITY INDICATOR (LSI)
9.10.1 Load Stability Indicator
Note: The Load Stability Indicator is NOT a serviceable item.
The LSI must be inspected and/or replaced by the local JLG
dealer.
The LSI (1) provides visual and audible indication of forward
stability limitations when machine is static on firm, level
surface.
• Green LED (2) will illuminate when LSI power is on.
• When approaching forward stability limitations LEDs
progressively illuminate, green (3), then orange (4) and
finally red (5).
• If the red LED iluminates, the warning buzzer also
sounds.
• The orange LED (4) illuminates when either of the
following occurs:
• The boom is fully retracted.
• The park brake is not applied and transmission con-
trol lever is in the forward or reverse position.
• When approaching forward stability limitations, visual
and audible indication is provided and the automatic
function cut-out and/or slow down feature is disabled.
• Travel in accordance with the requirements set forth in
Section 1 - General Safety Practices.
• When placing a load, ensure axles are not fully steered
in either direction.
• Test the LSI (6) at the beginning of each work shift.
1.Fully retract and level the boom, with no load.
Do not raise the boom during this test.
2.Level frame using level in cab.
3.Press the system check button on the LSI display. This
will cause all LEDs to flash on and an audible warning
to sound. This indicates that the system is
functioning properly. If the test gives a different
result, the system is not functioning properly and the
machine must be removed from service and repaired
before continued operation.
9.10.2 LSI Sensor
The LSI sensor (7) is bolted on the top left of the rear axle.
Note: If the rear axle is removed or replaced, the LSI Sensor
must be installed AFTER the rear axle is installed and setting on
all four wheels.
a. LSI Sensor Removal
1. Remove any fork carrier or attachment from the
machine.
2. Park the machine on a firm, level surface, level the
machine, fully retract the boom, fully raise the boom,
place the transmission in (N) NEUTRAL, engage the park
brake and shut the engine OFF.
WARNING
TIP OVER HAZARD. The LSI considers only longitudinal
stability limitations, observe all operating parameters.
Failure to follow operating parameters of the telehandler
could damage the equipment and/or cause tip over.
