Adjusting the tyre pressure
8.4.3.1
Dunlop valve
Figure 25:
Dunlop valve with union nut (1) and rim nut (2)
The tyre pressure cannot be measured on the simple
Dunlop valve. The tyre 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.
Unscrew and remove the valve cap.
Connect the bicycle pump.
Pump up the tyre slowly and pay attention to the
tyre pressure in the process.
The tyre pressure has been adjusted as per the
data [
Data sheet, page 1
].
If the tyre pressure is too high, unfasten the union
nut, let off air and tighten the union nut again.
Remove the bicycle pump.
Screw the valve cap tight.
Screw the rim nut gently against the rim with the
tips of your fingers.
