SECTION 3 - MACHINE CONTROLS AND INDICATORS
11. Creep Speed Indicator
When the Function Speed Control is turned to the creep
position, the indicator acts as a reminder that all func-
tions are set to the slowest speed. The light flashes if the
control system puts the machine into creep speed and
will be on continuously if the operator selects creep
speed.
12. Drive Orientation Indicator
When the boom is swung beyond the rear in either
direction, the Drive Orientation indicator will illuminate
when the drive function is selected. This is a signal for
the operator to activate the Drive Orientation Override
Switch and verify the drive control direction is correct.
