INSTALLATION
WARNING: The trailer tongue must be square or rectangular in profile for this Jack to mount
properly. A rounded tongue will allow the Jack to rotate to the side causing the trailer to fall
suddenly, causing potentially serious personal or property injury.
NOTE: Do not drill holes or otherwise damage the trailer tongue when installing this Jack. Failure
of the trailer tongue may result.
NOTE: Installing this Jack is most easily done with the Trailer mounted on the towing vehicle hitch.
1. Measure the trailer tongue for the best location to mount the Jack. Remember that the Jack must not
interfere with the Vehicle or trailer when turning or passing over speed bumps, boat ramps, etc.
2. Adjust the Swivel Plate so the Jack is in the lowered position.
3. Hold the Jack against the trailer tongue, and using the Jack Handle (#9), lower the Inner Tube (#6)
and Caster Wheel (#7) to the ground.
4. Using the (4) Hardware sets (#2) and (2) Mounting Bars (#5), attach the Jack to the trailer tongue.
The Mounting Bars must run across (perpendicular) to the trailer tongue. NOTE: You may wish to
use some removable thread locking compound on the bolt threads to help secure them.
5. Test the operation of the Trailer Jack. Make adjustments if necessary.
6. Tighten the mounting hardware firmly.
OPERATION
Dismounting the trailer from the towing vehicle.
WARNING: Before dismounting, make sure the trailer wheels are properly chocked to prevent the
trailer from rolling.
1. With the trailer on the hitch, pull the Swivel Handle (#8), allowing the Jack to rotate downwards.
WARNING: Keep your fingers away from the Swivel Plate area, and do not allow the caster to
strike your foot, as the Jack rotates downward.
2. Assure that the Swivel Handle pins are in place, locking the Jack into the lowered position.
3. Rotate the Jack Handle (#9) counterclockwise to lower the Caster Wheel Assembly (#7) to the
ground. Continue to crank just enough for the Trailer Jack to take the weight of the trailer. This will
make it easier to disengage the trailer hitch.
4. Disengage the trailer hitch. Remember to disengage any safety chains, electrical connections and
other connections between the vehicle and the trailer.
5. When the vehicle is completely clear, and it is safe to do so, drive the vehicle away from the trailer.
WARNING: Be sure to have a spoter watch this operation to be sure the trailer is clear of the
vehicle, and that the trailer does not roll away.
Using the Jack to mount the trailer to the towing vehicle.
WARNING: Do not attempt to lift the trailer tongue if it is too heavy for you.
NOTE: You may need assistance for some parts of this operation.
1. If the trailer tongue is resting on the ground, pull the Swivel Handle (#8) allowing the Trailer Jack to
rotate downward. Keep your fingers clear.
2. If you are able, lift the trailer tongue, while the Jack rotates into the lowered position.
3. Pull the Swivel Handle out, then re-engage the pins, locking the Jack into the lowered position.
4. Rotate the Jack Handle (#9) clockwise to raise the trailer to the level of the towing vehicle’s hitch.
5. Have an assistant spot for you as you move the vehicle close to the trailer. Or, if on smooth ground,
roll the trailer to the vehicle.
6. Mount the trailer onto the towing vehicle’s hitch.
7. Turn the Jack Handle counterclockwise to raise the Jack slightly, transferring the trailer weight
onto the towing vehicle.
8. Pull out the Swivel Handle, and rotate the Jack into its upright position. Be sure that the Swivel
Handle locking pins are fully engaged before driving away.
