may have Soft Touch, SkyGuard, or both Soft Touch and Sky-

If equipped with SkyGuard, the switch
enables functions cut out by the Sky-
guard system to be operated again,
allowing the operator to resume use of
machine functions.
If equipped with both Soft Touch and
SkyGuard, the switch operates like
described above and allows the opera-
tor to override the system that has
experienced a cutout situation.
13. Soft Touch/SkyGuard Indicator (If Equipped)
Indicates the Soft Touch bumper is against an object or the
SkyGuard sensor has been activated. All controls are cut out
until the override button is pushed. For Soft Touch, controls
are then active in the Creep Mode or for SkyGuard, controls
will work normally.
When Soft Touch is active, the indicator will be on continu-
ously and the alarm will sound. When SkyGuard is active, the
indicator will flash, and the horn will sound continuously.
