3. Extend the jack by pushing the operating switch (#4) at
the front of the jack upward and release the switch when
the desired height is achieved. Push the switch down to
retract the jack. The wireless remote control can also be
used (see Wireless Remote Control).
4. The jack stops automatically at the end of the extension or
retraction stroke. Try to move the jack in the opposite
direction. If it retracts, extend the foot pad for additional
height. If it fails to move, consult the Troubleshooting section.
5. The internal circuit breaker may trip if the load strains the
jack, switching off the motor. Release the operating switch
and wait 15 seconds for the breaker to reset before
attempting again. Reduce the load by removing items from
the trailer when raising or lowering.
6. After hitching the trailer to a tow vehicle, slide the drop leg
fully into the jack tube (#18), secure it with the safety lock
pin and retract the jack tube.
6.1 You may have to raise the drop leg slightly to release
pressure on the lock pin.
CRANK
1. Disconnect power to the jack. Do not use the crank when
the motor is powered.
2. Access the drive collar by removing the plastic cap, then
insert the crank (#27) into the drive collar.
3. Turn the crank counterclockwise to extend the inner tube
and clockwise to retract it.
4. Once the hitch and towing ball are aligned, retract the inner
tube until they are nearly touching. Crank clockwise to
lower the trailer tongue by smaller increments until the
weight transfers to the vehicle’s ball mount.
5 Continue to crank to retract the jack.
6. Complete the process to prepare the trailer for towing.
