Unhitching Instructions
NOTE: Prior to unhitching from the tow vehicle, ensure the trailer is parked on a level surface and chock the tires of the trailer.
1.
Extend the inner legs of both front jacks (landing gear) to within 4-5" of the ground by pulling on the quick-release
pins.
2. To turn on the touch pad, press both "UP" and "DOWN" arrows (Fig. 1B and Fig. 1C) at the same time. The green
indicator LED (Fig. 1A) will turn on.
NOTE:
The touch pad will remain on as long as the user is pressing buttons. It will time out after approximately 7 minutes
without use.
Press the "UP" arrow (Fig. 1B) to extend the front jacks and lift the front of the trailer to take the weight of the trailer off of the hitch.
Uncouple the trailer connection on the tow vehicle.
Pull the tow vehicle away and park at a safe distance.
Auto Level
1.
After unhitching from the tow vehicle and parking the vehicle at a safe distance away from the trailer. Press both "UP"
and "DOWN" arrows (Fig. 1B and Fig. 1C) at the same time if the green indicator LED is not on. Press “AUTO LEVEL”
(Fig. 1D).
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.
Auto Level Sequence
1. When Auto Level Sequence begins, the front of the trailer will seek a position near a level state.
2.
Rear jacks will be grounded.
3.
A side-to-side leveling sequence will occur.
NOTE: At this point on the 6 point system, the 2 middle jacks will be grounded to stabilize the trailer.
These 2 jacks do not level the trailer.
4.
Each jack will perform a final grounding touch.
NOTE: If the AUTO LEVEL sequence does not perform as described above, locate the OneControl Touch Panel inside the
trailer 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).
Hitch Recognition
1.
To turn on the touch pad, press both "UP" and "DOWN" arrows (Fig. 1B and Fig. 1C) at the same time. The green
indicator LED (Fig. 1A) will turn on.
2. Press "HITCH HEIGHT" (Fig. 1E). The rear jacks will retract.
The front of the trailer will raise to the height where the auto level sequence was started.
NOTE:
If the front of the trailer was below level when the Auto Level process was initiated, the hitch recognition feature
will retract the rear jacks but will not retract the front jacks to lower the trailer to the initial hitch height. This feature
helps prevent injury and/or damage to anything underneath the trailer.
Connect tow vehicle and make sure trailer and hitch are connected and locked.
Press "RETRACT ALL." (Fig. 1F). System will immediately retract all jacks.
Use the quick release pins on the landing gear to manually return the inner jack leg to fully retracted position.
