IV. WHEELCHAIR USE & CONFIGURATION
O. Wheel Locks
WARNING: Underinflated or worn tires may cause your wheel locks to not function
properly. Failure of the wheel locks to hold your chair could cause a loss of control or fall
resulting in serious injury or death.
How to Adjust Your Wheel Locks
NOTE: Always loosen and tighten wheel hardware by alternating between the two bolts
while loosening/tightening a little at a time. This prevents overclamping on one set of
hardware which leads to binding of the fasteners and increased difficulty in removal.
1. Use a 5mm Allen wrench to turn one of the screws in the clamp until it runs easily (less than
one turn).
2. Repeat step 1 with the second screws so the clamp can be adjusted on the frame.
3. Adjust the clamp along the frame so the wheel lock properly compresses the tire and
prevents any wheel movement. See Fig. 13.
4. Retighten the screws.
5. Always test new wheel lock positioning on a flat level surface. Once wheel locks are
engaged, the wheels should not slip or move. If the wheel locks are not fitted properly
readjust wheel lock again. See Fig. 14.
