10.3 Adjusting Patient-Operated Wheel Locks

 If wheels are pneumatic, before adjusting or replacing the wheel lock assemblies, ensure that the tires are inflated to the recommended psi
on the side wall of tire. The recommended tire pressure is located on the side wall of the tire.
1. Disengage the wheel locks.
2. Loosen the bolt and locknut that secure the wheel lock 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
occupied wheelchair in place when pushed.
4. Securely tighten the bolt and locknut or socket screws 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.
 Any wheel lock adjustment should embed the wheel lock
shoe at least 1/8-inch (3/16-inch if pneumatic tire) into the
tire when engaged.
7. Repeat STEPS 1-6 until the wheel lock shoe embeds the tire 1/8-inch
(3/16-inch for pneumatic tires) and holds the occupied wheelchair in
place when pushed.
8. If the measurement of 1/8-inch (3/16-inch for pneumatic tires) can not
be achieved, remove the bolt and locknut that secure the wheel lock
to the wheelchair frame and mount the wheel lock in the remaining
mounting position.
9. Repeat STEPS 1-8 for the opposite wheel lock.
10. Engage both wheel locks and ensure the occupied wheelchair is held in
place when pushed.
WARNING
If wheel locks DO NOT hold the occupied wheelchair in
place, contact a qualified technician. Otherwise injury or
damage may occur.
