Joystick control is equipped with detent
coils. When engine starts, detent coils
are energized by electricity. Four posi-
tions can have detent coils: TILTBACK,
RAISE, FLOAT, and AUXILIARY.
Operator must pull FLOAT and AUXIL-
IARY levers out of detent position by
hand. When joystick control is rotated to
90 percent of lever travel, retainer con-
tacts detent coil. Detent coil holds
retainer. Joystick will be held in position
until kickout switch interrupts flow of
current to detent coil. Detent coil de-
energizes and lever assembly can return
to HOLD position. Plunger initiates a
force against cup to assist spring in pull-
ing retainer from detent coil.
