WARNING

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

NOTE: If wheels are pneumatic, before adjusting the wheel lock assemblies, ensure that the tires are inflated to the recommended psi on the side wall of 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 11/8 inch ( inch for pneumatic tires) and holds the occupied wheelchair in place when pushed.

4.Securely tighten the bolt and locknut attaching 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 .

NOTE: 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 other tires) and holds the wheelchair in place when pushed.

8.Repeat STEPS 1 ‐ 7 for the opposite wheel lock.

9.If the measurement of 1/8 inch (3/16 inch for other 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.

10.Repeat STEPS 1 ‐ 8.
