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 drive wheels are equipped with a quick-release axle system as standard equipment. To keep this system
operational, ensure that no dirt adheres to the quick-release axle or receiver bushing. Periodically lubricate the
quick-release axle lightly with thin, resin-free oil (sewing machine oil).
•
If the wheelchair becomes wet, it should be rubbed dry again.
8.2 Repair
WARNING
Prohibited repairs
Severe user injuries, damage to the product due to adjustment and installation errors

personnel.
8.2.1 Inner tube, rim tape and tyre replacement
CAUTION
Improper tyre replacement
Injuries to the user due to incorrect installation, product damage
► No person is permitted to sit in the wheelchair during tyre replacement
► Before removing a wheel, support the product so it cannot tip over.
► Always replace the tyres in pairs. Two differently worn tyres affect the directional stability of the wheelchair.
INFORMATION
When driving outdoors, always carry a repair kit and tyre pump (when using pneumatic tyres) in case of emer
gency.
Suitable tyre pumps are listed on the order form and are supplied with the product. An alternative is tyre foam,
which fills your tyre and then hardens (available from bicycle shops, etc.).
