IMPORTANT CAUTION - If equalizer bars are attached to the tow vehicle and the trailer
while operating the power tongue jack, you may experience the motor clutching the
moment the jack sees load. This will occur because you are lifting both the tongue of the
trailer and the rear of the tow vehicle. The 3000 lb power jacks cannot lift this excessive weight.
To overcome this excessive weight, you should upgrade to the 4000 lb power jack. The ball screw
mechanism utilized in this jack should allow you to lift this load.
