4. Glow Plug/Wait to Start Indicator
Indicates the glow plugs are operating. After turning on igni-
tion, 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 func-
tion, 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.

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 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.
