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 1500 lb. and

2500 lb. acme screw jacks cannot lift this excessive weight. To

overcome this excessive weight, you should upgrade to the 3500

lb. power jack. The ball screw mechanism utilized in this jack

should allow you to lift this load.
