Basic Jack Operation
Operation
Unhitching from a Tow Vehicle
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.
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.

4. Red indicator lights (Fig. 2B) may come on, indicating the current disposition of the unit. In this case,
the front and right sides of the unit are low.
5. Push “ENTER” (Fig. 1C). Both front landing gear jacks will go to ground and stop.
6. Push the “FRONT” button (Fig. 1G) extending the front landing gear to a sufficient height, which raises
the front of the unit off of the tow vehicle’s 5th wheel hitch plate.
