1. Before the first use, the lock fork must be adjusted according to the following steps. First, use the Allen wrench attached to the lock to loosen the Allen screw on the lock fork, so that the lock fork can rotate freely.

2. Place the unlocked lock above the steering wheel and turn the lock forks so that the distance between the two lock forks is slightly smaller than the inner diameter of the steering wheel. After the lock is tested correctly, screw the Allen wrench on the lock fork into the V-shaped locating groove on the lock beam screw with the Allen wrench.
