maintenance of your wheelchair. Regular maintenance is essential for
your safety and continued operation of your wheelchair.
Check tire wear
Examine tires at least once a week for surface wear and cracks and
replace them as needed. Replace solid rubber tires when they become
loose on the rims or cracks appear.
Check handrims
Check handrims at least once a week. Inspect each handrim for rough or
sharp edges and, if any are found, replace handrims (or wheels, if
equipped with integral handrims) immediately. Ensure that all hardware
is properly aligned and secure.
Check wheel lock engagement
Check wheel lock engagement at least once a week. See Adjust wheel
locks in Part V to adjust wheel lock engagement. If a wheel lock is worn
or damaged, replace it immediately. Inspect the hardware for looseness
or signs of wear.
Ensure that the locking mechanism operates smoothly. The locking
assembly should be tight enough so that the wheel can not rotate or the
lock slip. Check that the locking shoe does not press against the tire
when in the unlocked position. Excessive force should not be required to
either engage or release wheel locks. Oil the wheel lock pivot points with
one or two drops of 30 weight oil. Remove excess oil and dirt.
Check anti-tippers
Check the anti-tippers at least once a week. Ensure that the anti-tippers
are securely fastened and properly positioned.
Check handgrips and push handles
Check handgrips and push handles at least once a week. Ensure that
they are tight and securely fastened.
