ƽ WARNING
DO NOT attempt to stop a moving wheelchair with the wheel locks. Wheel locks
are not brakes.

are inflated to the recommended psi on the side wall of tire.
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.
3. Reposition the wheel lock so that when engaged, the wheel lock shoe embeds the tire
1/8-inch (3/16-inch for pneumatic tires) and holds the wheelchair.
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 "A".
