If the actuator is not moving, there are several things you can check on. Make sure that all plugs are plugged in their respective ports as shown in the manual.
Make sure that the battery is fully charged. Make sure that the red emergency button is in the up position. Make sure that the control box lights up when you insert the battery.
*For all control boxes, the actuator will not work if the charger is plugged into the control box.
Once you have completed all items on the check list and the problem continues, please contact customer service for further assistance.
