I General User Manual 31
The bike chain must not be on the smallest chainring
at the front and the small outer rear sprocket wheel
simultaneously. The bike chain must not be on the
largest chainring at the front and large inner sprocket
wheel at the rear simultaneously. Otherwise the bike
chain could jump off.
Never pedal backwards when changing gears as you
could damage the gear-shift mechanism.
Only make changes to the gear-shift system carefully
and in small increments. If settings are made incor-
rectly, the bike chain could jump off the sprocket
wheel and cause you to fall off the bike. If you are
unsure about what to do, have this work carried out
by a professional bike workshop.
Even if the gear system is perfectly adjusted, it can
produce noise if the chain is running at an extremely
sharp angle. This does not mean it is defective and
does not damage the drive. As soon as the chain is at
a more shallow angle, the noise will disappear.
Never ride without a spoke protector. If a spoke pro-
tector is not installed, you must have one retrofitted.
Otherwise the bike chain or rear derailleur could land
in the gap between the sprocket and the spokes.
You should therefore select the lowest gear (largest
sprocket wheel) via the gear-shift handle for the rear
derailleur carefully as otherwise the rear derailleur
could collide with the spokes and damage them.
