10 ANTI-TIPPERS/WHEEL LOCKS Adjusting Patient Operated Wheel Locks ƽ WARNING DO NOT attempt to stop a moving wheelchair with wheel locks. Wheel locks are not brakes. If wheel locks do not hold the occupied wheelchair in place, contact a qualified technician; otherwise injury or damage may occur.  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 the tire. Position wheelchair on a flat, level surface to perform this procedure. 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 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 "A".  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 the STEPS 1-6 until the wheel lock shoe embeds the tire 1/8 inch (3/16 inch for pneumatic 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) 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. 10. Repeat STEPS 1-8. 11. Engage both wheel locks and ensure the occupied wheelchair is held in place when pushed. Part No 1110546 55 Invacare® Tracer™ EX2 Wheelchair
