22.3 Wheel camber
The wheel camber increases the lateral
stability of the product but also increases the
overall width of the product.
The wheel camber will be carried out according
to the order and can be subsequently changed
on angle-adjustable caster wheel bearing
blocks by replacing the drive wheel bearings
(with integrated wheel camber). If you want to
make a change to the wheel camber, please
contact your rehabilitation specialist dealer or
PRO ACTIV.
22.4 Air pressure
Check the tyre inflation pressure at regular
intervals as well as after extreme influence of
temperature (not on solid rubber tyres). The
maximum and if applicable, minimum tyre
pressure is printed on the side of the tyre.
This should be observed.
If the tyre pressure is too low, then optimal
functionality of the knee lever brake is not
ensured. Apart from that, there is an increased
risk of a flat tyre.
The tyre pressure increases with the
temperature. If the pressure is too high, the
tyre may burst. For this reason, product tyres
may not be exposed to unusually high
temperatures such as in a sauna or under
glass in the summer.
When inflating the tyre, make sure that the
prescribed air pressure is not exceeded.
To check or correct the air pressure,
proceed as follows:
1. Secure the product to prevent it rolling
away.
2. The drive wheel is normally fitted with a car
tyre valve. Unscrew the valve cap.

3. Place the valve attachment of the
compressed air device or the compressor
onto the valve (if necessary, an adapter
must be placed on the valve attachment)
and, if a clamp lever is fitted, secure the
connection by applying the lever.
4. Now check the air pressure. If the air
pressure does not match the
specifications, now correct the air
pressure.
5. Finally release the clamp lever (if present),
pull the valve attachment off the valve and
replace the valve cap.
