7.4.1.3 Checking and adjusting the tyre
pressure
Dunlop valve
Only applies to S pedelecs 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.
1
Unscrew and remove the
valve cap.
2
Connect the bicycle pump.
3
Pump up the tyre slowly and pay attention to
the tyre pressure in the process.
4
Correct the tyre pressure according to
specifications in the S pedelec pass.
5
If the tyre pressure is too high, unfasten the
union nut, let air out and re-tighten the union
nut.
6
Remove the bicycle pump.
7
Screw the valve cap tight.
8
Screw the rim nut gently against the rim with
the tips of your fingers.
Presta valve
Only applies to S pedelecs with this equipment
It is recommendable to use
a bicycle pump with a
pressure gauge. The
operating instructions for
the bicycle pump must be
adhered to.
1
Unscrew and remove the
valve cap.
2
Open the knurled nut
around four turns.
3
Carefully apply the bicycle
pump so that the valve
insert is not bent.
4
Pump up the tyre slowly and pay attention to
the tyre pressure in the process.
5
Correct the tyre pressure as per the
specifications on the tyre.
6
Remove the bicycle pump.
7
Tighten the knurled nut with your fingers.
8
Screw the valve cap tight.
9
Screw the rim nut gently against the rim with
the tips of your fingers.
7.4.1.4 Checking and adjusting the tyre
pressure – Schrader valve
Only applies to S pedelecs with this equipment
It is recommendable to use a
bicycle pump with a pressure
gauge. The operating
instructions for the bicycle
pump must be adhered to.
1
Unscrew and remove the
valve cap.
2
Attach the bicycle pump.
3
Pump up the tyre slowly
and pay attention to the tyre pressure in the
process.
The tyre pressure has been adjusted as per the
specifications.
4
Remove the bicycle pump.
5
Screw the valve cap tight.
6
Screw 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 against the
specifications.
Adjust the tyre pressure
as necessary.
