WARNING: The trailer tongue must be square
or rectangular in profile for this Jack to mount
properly. A cylindrical tongue will allow the Jack to
rotate off to the side and the trailer may suddenly
fall, potentially causing serious personal injury or
property damage. Do not drill holes or otherwise
damage the trailer tongue when installing this
Jack, as failure of the trailer tongue may result.
Install the Jack with the Trailer mounted
on the towing vehicle hitch.
1. Measure the trailer tongue for the best location
to mount the Jack. Consider the following:
a. The Jack will fit a 3″-5″ high tongue. Position
the Mounting Plate horizontally for a 3″ to 4″
tall location or vertically for a 4″ to 5″ location.
b. Allow room on both sides of the mounting location
for the Jack to swing up to its horizontal position.
c. Check that the Jack will not interfere with
the Vehicle or trailer when turning or passing
over speed bumps, boat ramps, etc.
d. d. To prevent overloading the jack, attach
it as near to the coupler as is practical.
2. The Mounting Hardware includes four mounting
bolts, washers, spring washers, and nuts to attach
the Jack. Position the Rotating Plates so that the
mounting bolts are as close as possible to the top
and bottom edge of the trailer tongue. Use the
configuration that best fits the trailer tongue.
Note: Insert the Bolts from the Rotating
Plate side, so that the Nuts and Bolt ends do
not interfere when rotating the Jack.
3. Test the operation of the Trailer Jack. Rotate
the Crank clockwise to raise the Trailer Jack
and counterclockwise to lower it. Pull the Swivel
Handle and rotate the Trailer Jack so it’s in line
with the trailer tongue, then rotate it down so the
wheels are on the ground. Make sure that the
Jack is able to lock into both of its positions.
4. Make any adjustments to the Trailer Jack
location as necessary, then tighten the
Mounting Hardware firmly to 15-20 ft. lb. Use
a torque wrench to confirm tightness.
