Important Note: If the top of your trailer's side rail is made of round tubing larger than 2 inches in diameter, you will need longer mounting bolts before beginning the installation process. Alternatively, you can spot-weld the Lift on the side rails instead of using mounting bolts. When mounting the Lift, ensure that your housings are straight, level, and flush to ensure proper installation. Assembly and Use STEP 1.
FIG. 1-0 That the housings are straight and level on the rail and flush against each other; Mark the center of housing B's mounting holes, as FIG1-1 and FIG1-2. In most cases, L1≈1/4 inch as FIG1-3. FIG. 1-1 FIG.
FIG. 1-3 Remove housing B from the side rail without disturbing the placement of housing A. Mark the center of housing A's mounting holes, as shown in FIG1-4 and FIG1-5 FIG. 1-4 FIG.
2) Mark the center of housing A&B's mounting holes. Drill 1/2-inch holes (which are oversized) down through the side rail where you made your marks. WARNING！L1≈1/4 inch, If you must install L1 greater than 1/4 inch, you must make sure that cables cannot rub against the end of side rails when lowering the tailgate all the way down to the ground. (0＜L2), Avoid fray and eventually break. FIG. 1-6 3)Install housing A and B.
To install, insert the bolts through the mounting holes located at the ends of housings A and B, where they come together. Then, place the housings back on the rail while guiding the bolts through the appropriate 1/2-inch holes that you have drilled into the side rail. It is crucial to ensure that the mounting bolts are seated all the way down into their square holes and remain seated when connecting and tightening to the side rail. The oversized 1/2-inch holes that you drilled will allow you to do this.

1)First, the tailgate is placed on the ground, and measure the approximate position of the hook on the tailgate. In most cases, L is between 20 inches and 35 inches. Warning!

almost any position and allow it to move up and down with minimal effort. B. If there is too much lifting power on the tailgate, and it will not go completely down or stay completely down, please refer to TROUBLESHOOTING #2.
