Wear suitable protective clothing,
protective gloves and protective
goggles during all installation and
maintenance work. Otherwise, dirt or inju-
ries that may be caused by lubricants and
auxiliary devices for the motor among other
things may result.
Chain
Cleaning the chain
To ensure it works effectively, the pedelec chain
has to be cleaned and greased regularly (see
page 38). Dirt can be removed when washing
the rest of the pedelec. Otherwise you can clean
the chain by rubbing it with an oily cloth. If it is
clean, it should be lubricated at the joints with the
appropriate lubricant. After a while, the excess
lubricant should be wiped off.
Chain tension
To ensure that the chain and gears
work safely, the chain has to have a
certain level of tension. Derailleur
gear systems tense the chain automatically.
For gears that are mounted without a chain
tensioner, the chain must be tightened if it is
found sagging. It might otherwise jump off
the gears and lead to a fall.
In the case of pedelecs with adjust-
able dropouts, the mounting screws
of the axle housing
should be loosened and tightened, and not
the axle nuts. If the bottom bracket shell
contains an eccentric bush, please tighten
the chain according to the instructions pro-
vided by the corresponding manufacturer.
Make sure that the axle nuts are
correctly fastened!

Dirt and permanent strain wear the
chain. The chain should be replaced
as soon as it can be sig-
nificantly lifted (approx. 5 mm) from the front
chain ring. Modern chains for derailleur gear
systems no longer have chain connectors.
Specialised tools are needed to open/
change/close them. This work should be
carried out by a professional or a specialist
retailer.
Other chains are supplied/assembled with
chain connectors. In some cases, these can
be opened without the need for tools. These
chain connectors can also be used to repair
a damaged chain on a ride if they have the
correct width for the drivetrain.
