Operation

The numbered buttons 1-4 and 7-0 correspond to the jack locations while looking forward from the rear of 

the camper. Arrows on the buttons indicate the direction of the camper movement. Red buttons raise the 

camper and blue buttons lower the camper.

1.  Press and hold button 6 (Fig. 1) (All Up) to raise the camper.

NOTE: Because the weight of the camper is not the same at all four corners, the jacks will not raise and 

lower at the same speed. Take care not to get the camper more than four inches out of level. When 

running all four jacks, stop often to check level and make sure all four jacks are on the ground.

2.  Press buttons 1-4 and 7-0 to raise or lower jacks individually to help level camper.

3.  Press and hold button 5 (All Down) to lower the camper and retract the jacks.

4.  Once the jacks are retracted for travel, reverse the motors and extend the jacks slightly. This prevents 

the jacks from locking up in the fully retracted position.

Safety Features

Overcurrent Shutdown

When any jack reaches the end of travel, either at full retraction or full extension, an overcurrent situation 

will cause the remote to shut down operation of all jacks and sound an alarm.

1.  At the time of the alarm, press each jack button individually in the direction of travel.

2.  When the alarm sounds again, this is the jack which has amped out and cannot be moved farther in 

that direction. Operation of the other jacks is not affected unless they reach the end of travel and amp 

out as well.

Never leave jacks bound in either the fully extended or fully retracted position.

Never allow the back of the camper to become higher than the front. The camper will load best and 

more safely if the front is kept two to four inches higher than the rear.

Always keep the motor release/locking lever on the side of the jack in the up (engaged) position 

except when the hand crank is installed.

Never lift beyond the DANGER warning on the jack's inner leg. Jack damage could result, 

compromising jack performance and creating a safety hazard with repeated overextension.

Never leave the jack fully retracted. Once the jacks are retracted for travel, reverse the motors and 

extend the jack slightly. This prevents the jack from locking up in the fully retracted position.

3.  A bind due to uneven loading of the jacks may also cause the motors to amp out. Reverse the jack, 

correct the load issue and continue to load or unload.
