Adjusting the tire pressure
Dunlop valve
The tire pressure cannot be measured on the simple
Dunlop valve. The tire pressure is therefore measured
in the filling hose when pumping slowly with the
bicycle pump.
It is recommendable to use a bicycle pump with a
pressure gauge. The operating instructions for the
bicycle pump must be adhered to.
u
Unscrew and remove the valve cap.
u
Connect the bicycle pump.
u
Pump up the tire slowly and pay attention to the
tire pressure in the process.
a
The tire pressure has been adjusted as per the
data [
w
Data sheet,
page

].
u
If the tire pressure is too high, unfasten the union
nut, let off air and tighten the union nut again.
u
Remove the bicycle pump.
u
Screw the valve cap tight.
Screw the rim nut gently against the rim with the
tips of your fingers.
