5. Enable Indicator/Footswitch
To operate any function, the footswitch must
be depressed and the function selected within
seven seconds. The enable indicator shows
that the controls are enabled. If a function is not selected
within seven seconds, or if a seven second lapse between
ending one function and beginning the next function, the
enable light will go out and the footswitch must be released
and depressed again to enable the controls.
Releasing the footswitch removes power from all controls
and applies the drive brakes.
NOTE: For engine starting, the footswitch must be in the released (up)
position.
TO AVOID SERIOUS INJURY, DO NOT REMOVE, MODIFY OR DISABLE THE FOOTSWITCH BY
BLOCKING OR ANY OTHER MEANS.
FOOTSWITCH MUST BE ADJUSTED IF FUNCTIONS ACTIVATE WHEN SWITCH ONLY OPER-
ATES WITHIN LAST 1/4" OF TRAVEL, TOP OR BOTTOM.
6. Low Fuel Indicator (Yellow)
Indicates fuel tank is 1/8 full or less.
NOTE: Refer to Fuel Reserve/Shut-Off System in Section 4 for detailed
information.
7. Creep Speed Indicator
When the Function Speed Control is turned to
the creep position, the indicator acts as a
reminder that all functions are set to the slow-
est 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.
