7.4.1.3 Checking and adjusting the tyre
pressure
Dunlop valve
Only applies to bicycles with this equipment
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.
1Unscrew and remove the
valve cap.
2Connect the bicycle pump.
3Pump up the tyre slowly and pay attention to
the tyre pressure in the process.
4Adjust the tyre pressure according to
specifications in the bicycle pass.
5If the tyre pressure is too high, unfasten the
union nut, let air out and re-tighten the union
nut.
6Remove the bicycle pump.
7Screw the valve cap tight.
8Screw the rim nut gently against the rim with
the tips of your fingers.

around four turns.
3Carefully apply the bicycle
pump so that the valve
insert is not bent.

instructions for the bicycle
pump must be adhered to.

6Screw the rim nut (1) gently against the rim
with the tips of your fingers.
Notice
If the tyre pressure is too low in the tyre, the tyre
does not achieve its load bearing capacity. The
tyre is not stable and may come off the rim.
If the tyre pressure is too high, the tyre may burst.
Check the tyre pressure as per specifications.
Adjust the tyre pressure as necessary.
