SECTION 9—ANTI-TIPPERS/WHEEL LOCKS

Adjusting Patient-Operated Wheel Locks

WARNING

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

NOTE: For this procedure, refer to FIGURE 9.5.

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.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” of FIGURE 9.5.

NOTE: Any wheel lock adjustment should embed the wheel lock shoe at least 1/8-inch (3/16-inch for pneumatic tires) 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 wheelchair.

8.If the measurement of 1/8-inch (3/16-inch for pneumatic tires) cannot 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 1-7.

10.If the wheel lock is unable to properly engage the wheel, it may be necessary to install wheel lock shoe extensions.

Refer to Installing Wheel Lock Shoe Extensions on page 56.

11.Repeat STEPs 1-7.

12.Repeat STEPS 1-9 for the opposite wheel lock.

13.Engage both wheel locks and ensure the occupied wheelchair is held in place when pushed.
