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 "A" of FIGURE 4.  Any wheel lock adjustment should embed the wheel lock shoe at least 1/8-inch into the tire when engaged. 7.
