Adjusting Wheel Locks

After any adjustments, repair or service and before use, make sure all attaching
hardware is tightened securely. Otherwise injury or damage may occur.
DO NOT attempt to stop a moving wheelchair with the wheel locks. WHEEL
LOCKS ARE NOT BRAKES.
NOTE: For this procedure, refer to FIGURE 8.1.
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 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 ʺAʺ
of FIGURE 8.1.
NOTE: Any wheel lock adjustment should embed the wheel lock shoe at least 1/8-inch into the tire
when engaged.
7. Repeat the STEPS 1-6 until the wheel lock shoe embeds the tire 1/8-inch and holds the
wheelchair.
8. Repeat STEPS 1-7 for the opposite wheel lock.
9. If the measurement of 1/8-inch cannot be achieved, remove the bolt and locknut that
secure the wheel lock to the wheelchair frame and mount the wheel lock in one of two
mounting positions.
10. Repeat STEPS 1-9 until the wheel lock holds the wheelchair. If the correct
measurement still cannot be achieved, contact a qualified technician.
