Load Stability Indicator - LSI
The LSI (9) provides visual and audible indication of forward stability limitations
when machine is static on firm, level surface.
• Green LED (10) will illuminate when LSI power is on.
• When approaching forward stability limitations LEDs progressively illuminate,
green (11), then orange (12) and finally red (13).
• If the red LED illuminates the warning buzzer also sounds.
The LSI has two modes:
Active Mode (3706PS, 3707PS, 4014PS & 4017PS)
• As the telehandler reaches forward stability limitations and the red LED (13)
illuminates, the automatic function cut-out is activated. All boom, frame level
and outrigger functions are disabled except for boom retract (CE & AUS)
and boom lift (CE). Retract boom to re-enable functions.
• In some instances the LSI system may slow down or stop boom functions if
operated close to forward stability limitations. When LEDs begin to flash,
certain functions can not be operated. Retract boom and/or return the
joystick to neutral position for a short period to allow system to reset and
LEDs to stop flashing before proceeding with operation.
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.
