

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.



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.



If wheel locks DO NOT hold the occupied wheelchair in 
place, contact a qualified technician. Otherwise injury or 
damage may occur.
