  There are several reasons why your BIG RED JACKS Jack might not be lifting the load. The release valve may not be completely closed, so ensure you turn the handle clockwise. It's also possible that the weight capacity has been exceeded. Another potential cause is air in the hydraulics, in which case you should purge air from the system. The oil level might be low, so add oil as required. Finally, the power unit could be malfunctioning, requiring a replacement.
