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 sec-
onds. The enable indicator shows that the controls are
enabled. If a function is not selected within seven sec-
onds, 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 con-
trols 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 BOT-
TOM.
6. Fuel Level Indicator
Indicates the level of fuel 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 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.
