1.Ensure the wheel lock is in the open (unlocked position).

2.Loosen the bolt and locknut that secure the wheel lock assembly to the wheelchair frame.

4.Securely tighten the bolt and locknut securing the wheel lock to the wheelchair frame.

5.Engage the wheel lock.

6.Measure the distance the wheel lock is embedded into the tire as shown in detail ʺAʺ of FIGURE 9.1.
