Safety inspection & maintenance
It is highly recommended that the wheelchair be taken to a qualified dealer annually for a thorough inspection and maintenance / repair service.
General care
• Wipe off chrome / aluminum parts at least once per week using a clean, soft cloth.
• Clean all metal parts with auto wax or similar products.
• Dry the chair immediately if exposed to moisture.
• Do not use abrasive cleanser or materials that will scratch the finish of the chair.
• Clean the upholstery with a mild soap solution, rinse and wipe dry.
• Clean the hand grips with water only and dry thoroughly. Use of soap or ammonia based cleaning solutions may loosen the grips.
General
Inspect the entire wheelchair for broken parts, sharp edges and loose fasteners. Ensure that everything works and the chair rolls straight
without drag and does not pull to one side. Replace or tighten parts as needed. Inspect for bent frame and crossbars.
Frame and Cross braces:
Check that the frame and cross braces are not bent or dented. Check the tubing for cracks and rust. If such issues are found, take the wheelchair
to your local service dealer.
Upholstery
Inspect for any rips, tears or worn spots and replace as necessary. Inspect the upholstery screws and assure that all are present and tight.
Torn or worn upholstery may not support the user’s weight and could result in a fall with serious bodily injury.
Armrests
Check for cracks, looseness, or sharp edges.
Hand grips
Ensure the hand grips are tight and secure on the handles. They should not move or twist.
Footrests / legrests
Ensure the legrest assembly release works properly. Ensure the assembly automatically locks securely into place when attached and will not
accidentally unlock.
Front caster forks
Verify the forks swivel freely without binding. Check to ensure the casters roll freely by lifting the chair and spinning the castor. The castor
should come to a gradual stop. If the nut is too loose, the castor will flutter or shimmy. If the nut is too tight, the chair will be difficult to steer.
Check the bearings and clean the fork stem housing.
Front casters and rear wheels
Ensure the castor/wheel axle and nuts are tight. The fork housing and the rear and front wheels are constructed with low maintenance, sealed
bearings to keep dirt out and increase the durability of the chair. Bearings are also protected with an additional bearing spacer component.
Check that the wheels are not warped, cracked or otherwise damaged and the spokes are not broken. Replace as needed. Assure that the wheels
spin freely. Replacement and maintenance of wheel bearings should be completed by a qualified wheelchair technician only.
Front and rear tires
Solid tires require minimal maintenance. They should occasionally be cleaned with a damp cloth. Replace the tires if they become cracked,
excessively worn, or have flat spots.
Recliners (for models equipped)
Inspect the reclining mechanisms to ensure they are clean and work freely. Ensure the stabilizer bar locks securely into place.
