Note
First check whether the vehicle is equipped with puncture-proof tyres or

Depending on whether the vehicle is equipped with puncture-proof tyres or pneumatic
tyres, the process of disassembly and re-assembly will be different! You can recognise
puncture-proof tyres by the fact that they do not have a valve!

Injury hazard caused by uncontrolled movement of the mobility device!

If the wheelchair is fitted with pneumatic tyres, the wheel can explode if the air is
not released from the tyre before removing the wheel!
· Always release the air from the wheel before you remove it. Depress the small
tappet in the centre of the valve!
WARNING: Loss of a wheel!
If the bolts which secure the wheel are not tightened firmly enough, or if the
threaded holes in the casing are damaged by being tightened too much, the
wheel can come loose during travel!
