Basic Operation; Unhitching From A Tow Vehicle - Lippert Components Ground Control 3.0 User Manual

Basic Jack Operation
Landing gear (front jacks) can be operated any time the
system is "ON". By pushing the "FRONT" button (Fig. 22G),
both front jacks can be extended. By pushing either the
"FRONT" and "LEFT" (Fig. 22H) or "FRONT" and "RIGHT"
(Fig. 22I) 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.
22D), the front jacks can be retracted together by pushing the
"FRONT" button (Fig. 22G) or individually by pressing "LEFT"
(Fig. 22H) or "RIGHT" (Fig. 22I) buttons, while simultaneously
pressing the "FRONT" button (Fig. 22G).
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. 22H) and
"RIGHT" (FIG. 22I) 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. 22J) will extend both rear jacks at the
same time. To extend individual rear jacks, press the "LEFT"
(Fig. 22H) or "RIGHT" (Fig. 22I) buttons while simultaneously
pressing the "REAR" button (Fig. 22J), 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. 22D), the rear jacks can be
retracted together by pushing the "REAR" button (Fig. 22J)
or individually by pressing either the "LEFT" (Fig. 22H) or
"RIGHT" (Fig. 22I) buttons, while simultaneously pressing the
"REAR" button (Fig. 22J).
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.
