The most common cause of excessive beeping on Power Gear Hydraulic Jacks is lack of jack fluid (Usually Dextron III) Try adding checking the fluid level (JACKS FULLY RETRACTED AND VISUALLY VERIFIED add a cup of fluid and see if they still beep.
If all else fails (Tank full to the point of overflowing and still beeps) on the top of the tank is a pair of wires, they go to a 2-wire flat connector.. Unplug and twist one half 180 degrees and plug just one pin back in. This **SHOULD** stop it but caution.. Disables jack down sensor.
