4. 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" (6.3 MM) OF TRAVEL, TOP
OR BOTTOM.

ing engine.

Indicates the fuel tank is 1/8 full or less. When the light
first turns on, there are approximately four usable gal-
lons of fuel remaining.
