Check wheel lock engagement
Check wheel lock engagement at least once a week. If a wheel lock is worn or dam-
aged, 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 lock-
ing 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 (optional)
Check the anti-tippers at least once a week. Ensure that the anti-tippers are securely
fastened and properly positioned.
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
Check upholstery at least once a month. Inspect for rips, tears and worn spots.
Ensure that all upholstery-attaching screws are present, properly aligned, and well-
secured. Use a Phillips screwdriver to tighten upholstery 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 re-
placed immediately. It may not support body weight.
Check rear wheel adjustment
Inspect the wheels at least once a month. Check alignment by elevating the rear of
the Transport Chair on a stable object until the rear wheels clear the ground, or plac-
ing the Transport Chair upside down in a stable position such that the wheels can
spin freely. Spin the wheels; there should be no wobble or sideplay, and the wheels
should spin freely without binding. The bearings should be clean and rotate smooth-
ly. Check rim sideplay to verify that bearings are not too loose. If there is a problem,
contact your Graham-Field dealer. If adjustment is required, this should be done by
your Graham-Field dealer only.
