Inspect the wheels at least once a month. Check alignment by elevating
the rear of the wheelchair on a stable object until the rear wheels clear
the ground, or placing the wheelchair 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 smoothly. Check rim sideplay
to verify that bearings are not too loose. If there is a problem, contact
your Graham-Field authorized distributor. If adjustment is required, this
should be done by your Graham-Field authorized distributor only.
Check arms at least once a month. Inspect for sharp edges or cracks
which could weaken the arm, and replace if found. Ensure that all
attaching screws are present and tight. 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 at least once a month. Ensure that all mounting
hardware is securely fastened and that the backposts are not bent or
damaged. Contact your dealer if you observe cracking or peeling paint or
plating.
Check elevating legrests and footrests at least once a month. Inspect
the locking mechanisms to confirm sure fit. Check for cracks, burrs, or
sharp edges, and replace if found. Ensure that the legrest or footrest will
automatically lock securely in place and will not accidentally unlock. If
equipped with heel loops, ensure the anchor bolts are tight and secure.
