manual mode the jacks operate individually, the Twist
Protection Prevention System has been activated to
prevent frame twist. The OneControl Touch Panel or
OneControl App will display "Relieving frame twist." The
jacks will resume operating in pairs when the potential
frame twist has been relieved.

Unhitching from Tow Vehicle

NOTE: Prior to unhitching from the tow vehicle, ensure
trailer is parked on a level surface and chock the tires of
the trailer.

pinned securely in place with the clevis pin and hairpin
cotter pin.
1. Disconnect any wires, chains, or sway control that
may be equipped between the tow vehicle and the trailer.
Unlatch the trailer coupler.
2. Press the "EXTEND" (Fig.33I) and "FRONT" button
(Fig.33A) on the OneControl Touch Panel App in
Standard Mode to extend the Power Tongue Jack until the
foot touches the ground and the coupler clears the hitch
ball.
3. Disconnect the trailer wire connection at the tow
vehicle, if not previously completed.
4. Pull tow vehicle away and park at a safe distance.

Auto Leveling

1. Prior to auto leveling, ensure the trailer is unhitched
from the tow vehicle and the tow vehicle is parked a
safe distance away from the trailer.
2. Power on the OneControl Touch Panel App.
3. Press the "Leveler" icon (Fig.36A).
4. Press "AUTO LEVEL" (Fig.33J).
NOTE: Once the automatic leveling cycle has been
started, it is important that there is no movement in the
trailer until the leveling process is complete. Failure to
remain still during the leveling cycle could have an effect
on the performance of the leveling system.
NOTE: Sequence may vary slightly based on the height
of the trailer coupler prior to leveling.
5. When the Auto Level Sequence begins:
A. The system checks that the rear jacks are retracted.
B. The Power Tongue Jack may adjust depending on
the orientation of the trailer.
C. Front jacks will extend until movement of the trailer
is sensed.
D. The Power Tongue Jack will then retract.
E. The front jacks will extend/retract near level.
F. Rear jacks will extend and ground.
G. Trailer will level front-to-back and then side-to-side.
H. The Auto level Sequence will ground all jacks to
ensure all foot pads are on the ground.
I. The Auto Leveling sequence is complete when the
OneControl App indicates, "Auto Level Success."
NOTE: If the AUTO LEVEL sequence does not perform
as described above, locate the OneControl Touch
Panel or use the OneControl App to place the system in
Manual Mode. Test that the jacks operate correctly by
pushing their corresponding buttons on the OneControl
Touch Panel or App; e.g., "FRONT" button operates only
the front jacks, etc. (See "Operation - OneControl Touch
Panel" or "Operation - OneControl App" in this manual).
