System and Safety Information
Failure to act in accordance with the following may result in death or serious personal injury. The use of
the Ground Control 3.0 leveling system to support the unit for any reason other than which it is intended
is prohibited by Lippert’s limited warranty. The Lippert leveling system is designed as a “leveling”
system only and should not be used to provide service for any reason under the coach such as changing
tires or servicing the leveling system. Any attempts to change tires or perform other service while unit
is supported by the Ground Control 3.0 leveling system could result in damage to the 5th wheel and/or
cause death or serious injury.
Be sure to park the unit on solid, level ground. Clear all jack landing locations of debris and obstructions.
Locations should also be free of depressions. When parking the unit on extremely soft surfaces, utilize
load distribution pads under each jack. People and pets should be clear of coach while operating leveling
system. Never lift the unit completely off the ground. Lifting the unit so the wheels are not touching the
ground will create an unstable and unsafe condition.
