4. Glow Plug/Wait to Start Indicator
Indicates the glow plugs are operating. After
turning on ignition, wait until light goes out
before starting engine.
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.
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
OPERATES WITHIN LAST 1/4" OF TRAVEL, TOP OR BOTTOM.

6. Fuel Level Indicator
Indicates a low fuel condition in the tank.
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 will be on continuously if the operator
selects creep speed or if the control system puts the
machine into creep speed. In addition, if the control system
puts one or more individual functions in creep speed, the
indicator flashes when that function is selected.
