Roll away. Avoid situations which allow the trailer to roll away on the caster wheel and trailer wheels. If using the trailer jack on an incline, be sure to chock the wheels. Never leave the trailer unattended while on the jack if the wheels are not chocked. 2. Swivel failure. The swivel is very strong and exceeds the stated capacity of the jack. However abuse, corrosion or damage may cause the swivel to break. Regularly inspect the swivel for damage, and discontinue use if the swivel is damaged. 3. Loose mounting plates or hardware. Never operate this Trailer Jack if the mounting hardware is not secure on the tongue of the trailer. Regularly inspect the hardware for proper assembly. 4. Overloading. Never attempt to lift or support loads in excess of the rated strength of this Trailer Jack. Sudden failure of the Jack may result in serious personal or property injury. BE AWARE OF DYNAMIC LOADING! Suddenly dropping a load on the trailer that the jack is attached to may create, for a brief instant, an excess load, which may result in damage to the product and/ or personal injury. 5. Swing up before driving. Always check to be sure that the Jack is properly swung up into its raised position before driving. Driving with the Jack lowered can cause serious damage to property. This Trailer Jack is not designed for highway use. 6. Dollying on uneven surfaces. The Tire on this Jack makes moving your trailer without a vehicle convenient. However, moving the trailer on uneven or inclined surfaces can cause personal injury or potential damage to the Jack or other property. 7. Not to be used for aircraft purposes.

Assembly / 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. FIGURE 1 Handle (1) Tire (18) See detail inset in FIGURE 2.

To mount the Tire (18): Slide the Axle (10) through a Washer (9), the Inner Tube (8) Left Bracket, a Spacer (11), the Wheel, the other Spacer (11), the Inner Tube (8) Right Bracket, and the other Washer (9). Insert a Cotter Pin (12) through the axle on each side, and bend both over completely to secure. 3. Measure the trailer tongue for the best location to mount the Jack. Remember that, while in its storage position, the Jack must not interfere with the Vehicle or trailer when turning or passing over speed bumps, boat ramps, etc. 4. Pull on the Swivel Handle (15) to adjust the Swivel Plate (6), so the Jack is in the lowered position. 5. Hold the Jack against the trailer tongue while using the Jack Handle (1) to lower the Tire (18) to the ground. 6. Using the four Hardware Sets (19) and two Mounting Bars (20), 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 (not included) on the bolt threads to help secure them. 7. Test the operation of the Trailer Jack. Make adjustments if necessary. 8. Tighten the Hardware Sets (19) firmly and evenly. 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. This procedure requires at least 2 people to be present. 1. With the trailer on the hitch, pull the Swivel Handle (15), and rotate the Jack downwards. WARNING: Keep your fingers away from the Swivel Plate area (See FIGURE 2), and do not allow the Tire (18) 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 Handle (1) counterclockwise to lower the Tire (18) 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. You may need to extend the Jack further to clear the trailer hitch. 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 2 spotters watch this operation to be sure the trailer is clear of the vehicle, and that the trailer does not roll away.

Maintenance If you discover any damage, have all damaged parts repaired or replaced before using your Trailer Jack. 1. Regularly inspect the Springs (17) and Swivel Handle (15) locking pins to be sure they will properly engage and lock the Jack in both the up and down positions. Check all of the Hardware Sets (19) regularly to ensure that they are tight and the Jack is firmly attached to the trailer tongue. 2. Keep the Swivel Plate (6) lubricated with light grease. Inspect it regularly for damage. 3. Keep the crank mechanism (inside the Outer Tube (7)) and the top shaft of the Inner Tube (8) lightly greased. Ensure that this mechanism functions smoothly. 4. Inspect the Tire (18) regularly for damage. Keep the tire filled to a cold pressure of 30 PSI. Keep the axle lightly lubricated. 5. Inspect the entire unit for corrosion which may be caused by exposure to salt water or weather. Rinse thoroughly and re-lubricate promptly after being immersed in salt water. 6. Keep all moving parts lightly lubricated to prevent corrosion. If corrosion develops, you may paint exterior parts of the Jack to help arrest and prevent further damage.
