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).
Middle jacks, if equipped, can not be extended or retracted in standard mode or manual mode. Middle jacks can
only be operated in the special jack code error mode. In order to operate the middle jacks press "LEFT" (FIG. 1H) and
"RIGHT" (FIG. 1I) 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 trailer.

Unhitching From A Tow Vehicle

NOTE: Prior to unhitching from the tow vehicle, ensure the trailer is parked on a level surface and be sure to
chock the tires of the trailer.
1.
Extend the inner legs of both landing gear to within 4-5 inches of the ground by pulling on the quick
release pins.
2.
Push "ON/OFF" (Fig. 1K). LCD Screen will light up and display "READY JACKS: UP" (Fig. 2A).
3.
Push the "UP" arrow (Fig. 1A) to scroll to "Drop Front Jacks" option on LCD screen.
4. Red indicator lights (Fig. 2B) may come on, indicating the current disposition of the trailer. In this case,
the front and right sides of the trailer 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 trailer off of the tow vehicle's 5th wheel hitch plate.

Be sure to park the trailer on solid, level ground. Clear all jack landing locations
of debris and obstructions. Locations should also be free of depressions. When
parking the trailer on extremely soft surfaces, utilize load distribution pads
under each jack. People and pets should be clear of the trailer while operating
leveling system. Never lift the trailer completely off the ground. Lifting the
trailer so the wheels are not touching the ground will create an unstable and
unsafe condition.
