General care
Always evaluate the overall operation of your Transport Chair. It should function with ease and
should travel straight without excessive drag or pull to one side.
Remember, your Graham-Field dealer knows your Transport Chair best when it comes to ser-
vice and repairs. Contact your dealer with any questions or concerns regarding the safe opera-
tion and maintenance of your Transport Chair. Regular maintenance is essential for your safety
and continued operation of your Transport Chair.
Check caster tire wear
Examine caster tires at least once a week for surface wear and cracks and replace them as
needed. Always replace tires when they become loose on the rims or cracks appear.
Check wheel lock engagement
Check wheel lock engagement at least once a week. If a wheel lock is worn or damaged, have
your Graham-Field dealer 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 hand grips
Check hand grips at least once a week. Ensure that they are not ripped. Ensure that they are
tight and securely fastened.
Check upholstery and carrying handles
Check upholstery and carrying handles at least once a month. Inspect for rips, tears and worn
spots. Ensure that all upholstery-attaching and carrying handle-attaching screws are present,
properly aligned, and well-secured. Use a Phillips screwdriver to tighten mounting screws.
Check attaching screws for sharp edges or stripped screws, and replace if found.
WARNING: Worn or torn upholstery, or upholstery with loose hardware, must be replaced imme-
diately. It may not support body weight.
Check arms
Check arms at least once a month. Inspect for sharp edges or cracks which could weaken the
arm, and replace if found. Use a Phillips screwdriver to tighten arm pad mounting screws.
Check for burrs on the screw heads and replace if found. Ensure that screws do not extend into
the padding.
Check backposts / push handles
Check backposts at least once a month. Ensure that all mounting hardware is securely fastened
and that the backposts are not bent or damaged. Ensure that back folding mechanisms are
secure, work correctly, and that there is no play in back fold points. Contact your dealer if you
observe back play, cracking or peeling paint or plating.
