Check tires
Examine the tires periodically for wear, and replace as required.
Check wheel lock engagement
Check wheel lock engagement weekly. See Part VI, Adjust wheel locks, to adjust wheel locks.
Warning: If a wheel lock becomes worn or damaged, replace it immediately.
Clean & check upholstery
Clean the upholstery with a mild soap and water solution monthly. Ensure that all upholstery secur-
ing hardware is tight. If upholstery mounting screws are loose, use a Phillips screwdriver to tighten
them. Inspect upholstery mounting grommets to ensure that they are all properly aligned and se-
cured. Inspect for rips, tears and worn spots.
Warning: Replace worn or torn upholstery immediately. It may not support body
weight.
Clean Batteries
Perform this at least every three months. See Part VII, BATTERIES, BATTERY MAINTENANCE,
Clean batteries,
for this procedure.
Clean wheelchair
Clean and wax all chrome or painted parts at least every three months. Clean the metal parts with
a wax that contains a cleaner (auto wax). Do not use abrasive cleaners such as chrome cleaner or
scouring cleaners; these will scratch the finish. Never use steam or high pressure cleaners to clean the
wheelchair; they will remove protective coatings and lubricating oils.
Check caster forks
Check the caster stems/forks for proper rotation at least every three months. e caster fork must
swivel freely to facilitate steering and handling. Adjusting the stem nut varies the amount of force
required to turn the caster. If the nut is too loose, the caster will flutter or shimmy; if the nut is too
tight, the wheelchair will be difficult to steer. If the caster stem requires adjustment, or the caster
stem bearing requires replacement, visit a qualified Graham-Field dealer. Ensure that stems are firmly
attached to forks, and that forks and stems are not bent. Evaluate all threads, locking nuts and bear-
ings.
Clean battery terminals
Perform this at least every six months. See Part VII, BATTERIES, BATTERY MAINTENANCE,
Clean battery terminals
, or contact your Graham-Field dealer.
