(depending on frequency
of use)
10.1.2 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).
•
The drive wheels may be equipped with optional clamp axles. It is essential to ensure that particles of dirt do
not get between the axle and receiver bushing. The system is tolerance-free. Particles of dirt can prevent the
clamp axle from being removed.
•
The spokes should be lightly lubricated with petroleum jelly on occasion.
•
If the wheelchair becomes wet, it should be rubbed dry again.
10.2 Inspection
•
For reasons of product safety, an annual inspection is to be performed on this wheelchair type according to the
list below.
•
Under more severe conditions – e.g. in case of increased strain – the user should have an interim inspection of
the frame and chassis performed.
•
Product inspections may only be carried out by qualified personnel.
