Active wheelchair maintenance and service: a practical guide
A weekly check of an active wheelchair comes down to three things - the pressure in pneumatic tires, the tightness of the screws and play in the wheel axles. An annual service covers much more, including the condition of the bearings, frame stiffness, brake function and tire wear, and usually calls for a specialist's assessment. The two levels of checks catch different kinds of faults, so neither replaces the other.
Regular maintenance matters not only for riding comfort, but also for the life of aluminum parts such as the side guards, brakes and front casters, which make up most of the SPARX One construction. Neglecting simple weekly tasks usually leads to more expensive repairs at the annual service. That is why it is worth treating both levels of maintenance as complementary parts of the same routine, rather than as two separate chores.
In short
Tire pressure check - ideally every week with pneumatic tires, because pressure that is too low increases rolling resistance.
Annual service of a manual wheelchair - covers the bearings, play in the axles, tire condition and brake function.
Pressure washers - can damage the bearings and the paint finish, so it is better to clean the frame with a damp cloth.
SPARX One aluminum parts - the side guards, brakes and front casters should be dried after contact with moisture to avoid dirt build-up.

What should you check after every use of an active wheelchair?
After every use, wipe the frame, wheels and seat with a damp cloth to remove sand, mud and dust before they settle in the moving parts of the wheelchair. This simple task takes literally a moment, yet it significantly reduces the risk of small particles getting into the front caster bearings or the brake mechanism. Clean the upholstery with gentle, alcohol-free products, and for heavier dirt use a solution of soap and warm water. Regular cleaning after use is the simplest way to make weekly and annual checks shorter and cheaper.
How often should you check the pressure in pneumatic tires?
Check the pressure in pneumatic tires every week, because even a small drop in pressure increases rolling resistance and requires more force with every push of the wheel. Pressure that is too low also speeds up tire wear and increases the risk of damaging the inner tube when you hit a curb or a sharp edge. The check takes less time than pumping up the wheel, and regularity matters more here than the exact pressure value, because it is neglect, not a single underinflation, that leads to problems. With solid tires this task disappears completely, which is one of the main arguments for choosing them for everyday use.
What does an annual active wheelchair service include?
Manual wheelchairs should be serviced at least once a year, and the service covers the condition of the frame, wheels, brakes, upholstery and adjustable components. During such a service, the specialist checks above all the play in the axles, because this is what most quickly reduces the precision of steering the wheelchair. The check also covers tire pressure and tread wear, the stability and stiffness of the whole frame, and the function of the brakes and control mechanisms. A regular service is sometimes also a condition for keeping the manufacturer's warranty, so skipping it can have consequences that go beyond the technical condition of the wheelchair.
Why does a pressure washer damage bearings?
A pressure washer forces water under high pressure into places that normally stay dry, including the bearing seals of the front casters and the rear wheel axles. Water that gets into a bearing washes out the grease and speeds up corrosion of the internal parts, which later shows up as resistance or grinding while riding. A strong jet of water also damages the paint finish on the frame, especially at the welded joints, where the coating is thinner. Instead of a pressure washer, a gentle stream from a garden hose or simply a damp cloth works better, especially for aluminum parts that do not need intensive cleaning.
How to care for aluminum frame parts and side guards?
Aluminum parts, such as the side guards, brakes and front casters on SPARX One, resist corrosion much better than steel parts, but they still need basic care after contact with moisture. After riding in the rain, dry these parts with a cloth before moisture settles in the gaps between mounting components. Aluminum side guards also protect the frame from dirt thrown up by the wheels, so they need cleaning more often than the rest of the wheelchair. Avoiding harsh cleaning products and abrasive sponges keeps the surfaces looking good for longer.
What speeds up the wear of rubberized push rims?
Rubberized push rims, such as the GRIPY TETRA available as optional equipment for SPARX One, wear faster with frequent contact with rough surfaces, such as paving stones or coarse concrete. Regularly cleaning sand and small pebbles off the rubber reduces surface abrasion with every push of the wheel. Long exposure to strong sunlight and high temperatures also speeds up the aging of rubber, so storing the wheelchair in the shade matters not only for comfort, but also for the durability of the push rims. It is worth adding a check of the rubber surface to the same weekly routine as checking tire pressure.
When should a specialist service your wheelchair instead of you doing it yourself?
Basic tasks, such as cleaning the frame, checking the pressure or tightening visible screws, can be done yourself without specialist equipment. More advanced work, such as assessing play in the axles, adjusting the brakes or checking the stiffness of the welded frame joints, requires the knowledge and tools that a service center has. Treat the annual specialist service as a complement to, not a replacement for, your weekly home routine, because the two kinds of checks catch different problems. Combining regular care at home with an annual technical service is the most effective way to extend the life of the whole wheelchair.
Summary
Weekly routine - cleaning after use, checking the pressure in pneumatic tires and checking visible screws.
Annual service - assessment of the bearings, play in the axles, frame stiffness, tires and brakes, ideally by a specialist.
Avoiding pressure washers - protects the bearings and the paint finish from damage by high-pressure water.
Care for aluminum and rubberized push rims - drying after moisture and regular cleaning of sand extend their life.
