Installation Instructions
Before mounting the jack confirm that there will be no interference from the tow vehicle, tongue, ground, and any other mounted accessories while
stationary or in motion. Before installing, check for interference in all positions including handle swing and swivel positions. Check for interference
again after installation is complete. The height of the swivel mount is pre-set and torqued by the factory at a common height for most applications.
Adjusting Swivel Mount Height: (if necessary)
With jack removed from trailer, loosen the two swivel fasteners until the slide block moves freely along outer tube.
To access the upper bolt, be sure the swivel bracket is rotated in the horizontal (3” mounting) position as shown.
Adjust swivel mount to desired location and re-torque to 60-70 ft-lbs. After adjustment, check for proper swivel and
pin engagement.
