DRIVING AT CUTBACK – POT-
HOLE STILL ENGAGED
None
None
• Drive State = CREEP
While stowed, drive speed is reduced (due to lower
ground clearance) since the control system
detected that the pot-hole protection mechanism
is deployed (failed to retract). Clear the obstacle
blocking the pot-hole protection mechanism,
repair the mechanical problem, re-adjust the pot-
hole limit switches, or repair the wiring to correct
the problem. Alternately, there may be difficulty
with the Elevation Angle Sensor that causes the
Control System to improperly believe the platform
is stowed.

State =DRIVE.
