7.1.2 Maintenance Tasks

To ensure smooth operation at all times, some parts of the wheelchair can be maintained by users or attendants
with some technical skills:
• Hair and dirt frequently collect between the caster forks and the caster wheels; over time, they make the caster
wheels stiff to operate. Remove the caster wheels and thoroughly clean the forks and caster wheels using a
mild household cleaner.
• The rear 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 axle housing. Periodically lubricate the quick-release
axle very lightly with resin-free sewing machine oil.
• If the product gets wet it should be rubbed dry.
• Check the screw connections on a regular basis.
Screw connections should be periodically checked for tightness, especially during the initial period of use or
after making adjustments. If a screw connection comes loose repeatedly, contact the specialist dealer
promptly.
