Envelope Speed Reduction Screen
The Envelope Speed Reduction Screen appears if the JLG Control
System has sensed that the boom is approaching the edge of the
backward or forward operating envelope, which places all func-
tions in proportionally reduced speed. The proportionally
reduced speed function is indicated by the turtle icon in the
lower left corner of the screen. In the lower right hand corner, a
check mark in a green circle indicates no serviceable faults are
present. If a serviceable fault is present, the numeric fault code
with a safety alert symbol is displayed. Multiple faults will display
in succession. Check the Service Manual for the specific fault
code.
