Dynamo
The dynamo generates the required electrical
energy for the front headlight and the rear lights.
Hub dynamo
If your bicycle uses a hub dynamo, you can
switch this on and off easily on the rear side of
your front headlight with the on/off switch. The dy-
namo automatically switches on or off when the
lighting system of your bicycle has a light sensor.
In order to remove the front wheel,
you first have to remove the connec-
tion on the light cable.
To refit the light cable, the connecting terminal of
the hub dynamo has to be fitted on the right (fac-
ing forwards). Re-attach the connections correct-
ly and check that the lighting is working properly.
To do this, turn the front wheel and check if the
light comes on.
Failure of the lighting system
The lighting system is a key part
and it is vital that it is proper working
condition! Only have check-up and
servicing work done by authorized specialist
retailers after failures or temporary problems!
