    2. Attach the hooks of each SST arm across the diameter of the coil spring.

      CAUTION:


      • B005O7T

        Make sure that the hooks are securely attached to the coil spring.

      • If a hook disengages from the coil spring, the coil spring may fly out, resulting in injury.

      • B005N1L

        Make sure that the hooks of the upper and lower SST arms are attached to the coil spring so that the distance between the hooks is as large as possible.

      • If a hook disengages from the coil spring, the coil spring may fly out, resulting in injury.

      • B005L5A

        Make sure that the arms of SST are parallel and the number of coils between the arms is the same on each side.

      • B005QBJ

        Do not compress the coil spring to the point where the coils touch each other.

      • If a hook disengages from the coil spring, the coil spring may fly out, resulting in injury.

      • B005OE3

        Do not use an impact wrench.

      • If an impact wrench is used, the threads of SST may be damaged, or sudden compression of the coil spring may cause a hook to disengage and the coil spring to fly out, resulting in injury.

      • B005NM6N02

        If a stopper pin touches the coil spring while using SST, remove the stopper pin and continue with the procedure.

      • If a stopper pin is removed, install a coil spring stopper belt as shown in the illustration.
