Instructions for maintenance

4.2.1 Wheels and tyres

Proper working of the brakes depends on the state of the tyres, that can change due to wear
and contamination (water, oil, mud, ...).
• Keep your wheels free of wires, hair, sand and fibres.
• Check the profile of the tyres. If the tread depth is less than 1 mm, the tyres need to be replaced.
Contact your specialist dealer for this matter.
• Inflate the pneumatic tyres to the correct pressure (see pressure indication on the tyres).
• For instructions on how to change the tyres, see the installation manual.
4.2.2 Cleaning
CAUTION
• Keep the operating console clean and protect it from water and rain.
• Never use a hose or high-pressure cleaner to clean the wheelchair.
Wipe all rigid parts of the wheelchair with a damp cloth (not drenched). If necessary, use a mild
soap, suitable for varnishes and synthetics.
The upholstery can be cleaned with lukewarm water and a mild soap. Do not use abrasive
cleaning agents to clean.
Keep the ventilation openings of the battery charger clean and free of accumulated dust. Blow
away the dust and clean the battery charger enclosure with a slightly moistened cloth, if required.
