Care and Maintenance
General Care
Wipe off all metal parts at least once a week using a soft cloth. Dry
chair immediately if it is exposed to moisture. Abrasive cleaners or
materials will scratch the surface of the chair.
Tires
Minimal maintenance is required for rubber tires. Wipe with a damp
cloth occasionally. If tires become cracked or worn, replace immedi-
ately.
Front Casters
Inspect casters periodically and lubricate them when necessary. To
lubricate, remove the fork and grease the caster bearings. Remove the
wheel from the fork and grease the wheel bearings. The wheel and
fork can be reassembled by tightening the nuts until there is no play
remaining, but the wheel rolls freely. The fork will revolve freely when
adjusted correctly. The caster will flutter if the nut is too loose or be
difficult to steer if the nut is too tight.
Wheels
Inspect monthly for correct tightness. If the wheel seems to be loose
or wobbly, release the lock nut and tighten the axle bolt. Lean chair to
one side and spin adjusted wheel to check for correct adjustments.
Wheel Locks
Wheel locks should be checked for correct locking action before actu-
al use. Pushing the handle completely forward activates the wheel
locks. If the wheel locks are working correctly they will be embedded
into the tire at least 1/8". To adjust wheel locks, loosen nut on carriage
bolt. Slide clamp toward rear wheel until lock shoe is embedded at
least 1/8" into rear tire when lock handle is engaged. Tighten nut to
secure into position.
