INSTALLATION
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 Coupling Tube so the Jack is in the lowered position.
3. Hold the Jack against the trailer tongue, and using the Crank Handle (#5), lower the Inner Tube
(#3) and Skid Plate (#7) to the ground.
4. Using a suitable welder, weld the Tongue Adapter (#8) to the trailer tongue.
WARNING: Only a qualified and certified welder should attempt this. A poor weld may cause the
trailer to fall suddenly, potentially causing serious personal or property damage.
5. Attach the Trailer Jack by fitting the Coupling Tube (#1) over the Tongue Adapter (#8). Slide the
Locking Pin (#6) through the appropriate hole in the Coupling Tube and the Tongue Adapter to
secure the Trailer Jack to the trailer tongue.
6. Test the operation of the Trailer Jack. Place the Locking Pin in each of the holes of the Coupling
Tube/Tongue Adapter to make sure it holds the Trailer Jack in each of the posible positions. Make
adjustments if necessary. 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, support the weight of the Jack with one hand and pull the Locking Pin
(#6) out of the Coupling Tube (#1)/Tongue Adapter (#8), allowing the Jack to rotate downwards.
WARNING: Keep your fingers away from the Coupling Tube area, and do not allow the Skid
Plate to strike your foot as the Jack rotates downward.
2. Replace the Locking Pin into the Coupling Tube/Tongue Adapter, locking the Jack into the lowered
position.
3. Rotate the Crank Handle (#5) counterclockwise to lower the Skid Plate (#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 spotter 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 move the trailer tongue if it is too heavy for you.
NOTE: You will need assistance for some parts of this operation.
1. Make sure the trailer’s wheels are properly blocked to prevent unwanted trailer movement.
2. Move the towing vehicle in place so that the vehicle’s hitch is in close proximity to the trailer’s hitch.
3. Rotate the Crank Handle (#5) to raise or lower the trailer to the level of the towing vehicle’s hitch.
4. Have an assistant spot for you as you move the vehicle in close to the trailer’s hitch. Mount the trailer
onto the towing vehicle’s hitch.
