8.1.2 Maintenance tasks

To ensure smooth operation at all times, users or attendants with some technical skills can maintain some parts of
the product:
• Screw connections must be periodically checked for tightness, especially during the initial period of use or
after adjustments have been made to the wheelchair. If a screw connection loosens repeatedly, contact the
qualified personnel promptly.
• Particles of dirt and hair accumulate on the caster wheel axle and threaded axle of the caster fork over time.
This makes the steering stiffer. Regularly remove dirt and oil the axles. See the section "Approach in case of
stiffness".
• The rear wheels (drive wheels) may have been configured as a quick-release axle system. To keep this system
operational, ensure that no dirt adheres to the quick-release axle or receiver bushing. Periodically lubricate the
quick-release axle very lightly with thin, resin-free oil (sewing machine oil).
• Rub the product dry if it gets wet.
