Operation
Basic Jack Operation
Landing gear jacks can be operated any time the system is “ON”. By pushing the “FRONT” button (Fig. 1G), both
front or landing gear jacks can be extended. By pushing either the "FRONT" and “LEFT” (Fig. 1H) or "FRONT" and
“RIGHT” (Fig. 1I) buttons, the individual front jacks can be extended. If the touch pad is put in the retract mode,
indicated by the orange illuminated LED next to the “RETRACT” button (Fig. 1D), the front jacks can be retracted
together by pushing the “FRONT” button (Fig. 1G) or individually by pressing “LEFT” (Fig. 1H) or “RIGHT” (Fig. 1I)
buttons, while simultaneously pressing the “FRONT” button (Fig. 1G).
NOTE: Middle jacks can only be operated in error mode. In order to engage middle jacks, press "LEFT" and
"RIGHT" buttons simultaneously.
The rear jacks can only be extended when the touch pad is in the manual mode. Once system is in manual mode,
pressing the “REAR” button (Fig. 1J) will extend both rear jacks at the same time. To extend individual rear jacks,
press the “LEFT” (Fig. 1H) or “RIGHT” (Fig. 1I) buttons while simultaneously pressing the “REAR” button (Fig. 1J),
depending on which jack needs to be operated. If the touch pad is put in the retract mode, indicated by the orange
illuminated LED next to the “RETRACT” button (Fig. 1D), the rear jacks can be retracted together by pushing the
“REAR” button (Fig. 1J) or individually by pressing either the “LEFT” (Fig. 1H) or “RIGHT” (Fig. 1I) buttons, while
simultaneously pressing the “REAR” button (Fig. 1J).
NOTE: If the rear jacks will not operate individually using the method described above, but they operate
properly when Auto Level is performed, the Twist Prevention Protection system has locked out the
operation to prevent damage to the frame of the unit.
Auto Level
NOTE: Prior to unhitching from the tow vehicle, ensure unit is parked on a level surface and be sure to chock
the tires of the unit.
1. After unhitching from tow vehicle, press Auto Level (Fig. 1F).
NOTE: Once the automatic leveling cycle has been started, it is important that there is no movement in the
coach until the unit has completed the leveling process. Failure to remain still during the leveling
cycle could have an effect on the performance of the leveling system.
NOTE: In order for hitch recognition feature to function, the auto level sequence MUST be started with the
front of the unit above level.
