Cleaning, servicing and inspection
Dunlop valve
Only applies to pedelecs with this equipment
The tyre pressure cannot be measured on the
simple Dunlop valve. You thus measure the tyre
pressure in the filling hose while slowly pumping
the bicycle air pump.

It is recommendable to use a bicycle air pump
with a pressure gauge.
1 Unscrew and remove the valve cap.
2 Undo the rim nuts.
3 Connect the bicycle air pump.
4 Pump up the tyre slowly and pay attention to
the tyre pressure in the process.
5 Correct the tyre pressure to meet the specified
value in the Pedelec pass.
6 If the tyre pressure is too high, unfasten the
union nut, let air out and re-tighten the union
nut.
7 Remove the bicycle air pump.
8 Screw the valve cap tight.
9 Screw the rim nut gently against the rim with
the tips of your fingers.

Correct tyre pressure if necessary (see
section
6.5.7 ).

It is recommendable to use a bicycle air pump
with a pressure gauge. You must observe the
bicycle air pump operating instructions.
1 Unscrew and remove the valve cap.
2 Open the knurled nut around four turns.
3 Carefully attach the bicycle air pump so that
you do not bend the valve insert.
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 air pump.
7 Tighten the knurled nut with your fingers.
