If the tyre pressure is too low, the opti-
mum functional capability of the knee lever
brake and the integral brake is not guaranteed,
and an excessively low tyre pressure influ-
ences the driving behaviour negatively. 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 temper-
atures such as in a sauna or under glass in the
summer.
When inflating the tyres, make sure that
the prescribed air pressure is not exceeded.
To check or correct the tyre pressure
, pro-
ceed 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.

Figure 85: Valve without cap
3. Place the valve attachment of the com-
pressed 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 tyre pressure. If the tyre
pressure does not match the specifica-
tions, correct it.
5. Finally release the clamp lever (if present),
pull the valve attachment off the valve and
replace the valve cap.
