Troubleshooting, fault clearance and repair
9.1.7 Other errors
9.2 Repair
Special knowledge and tools are required for
many repairs. That is why only a specialist dealer
may perform repairs such as:
• Replacing tyres and rims
• Replacing rims and brake linings or brake discs
• Replacing and tensioning the chain.
9.2.1 Original parts and lubricants
The individual pedelec parts have been carefully
selected and matched to one other.
Only original parts and lubricants must be used for
maintenance and repair.
The constantly updated accessory approval and
parts lists are in Section 11 Documents and
Drawings.
Observe the operating instructions for the new
components.
9.2.2 Replacing the lighting
Only use components of the respective power
class for replacement.
9.2.3 Adjusting the headlight
The headlight must be set, so that its light beam
shines on the road 10 m in front of the pedelec.
9.2.4 Tyre clearance check
The tyre needs to be checked each time a
suspension fork tyre is changed to another size.
1 Release pressure from the fork.
2 Press fork together fully.
3 Measure the gap between the top of the tyre
and the crown's lower surface. The gap must
not be less than 10 mm. If the tyre is too large,
the tyre will touch the crown's lower surface if
the fork is fully pressed together.
4 Release pressure on fork and pump it up again
if it is an air suspension fork.
5 Take into account the fact that the gap will be
smaller if there is a guard. Check again to
ensure that there is sufficient clearance for the
tyre.
Symptom Cause Remedy
Two beeps will sound if a
switch is pressed but the
switch cannot be
operated.
Pressed switch mode has been
deactivated.
This is not a malfunction.
Three beeps are
sounded.
A fault or warning has occurred.
This occurs when a warning or an error is shown on the
display screen. Follow the instructions for the code indicated
on screen in Section 6.2 System Messages.
When you use an
electronic gear shift, you
can feel that pedal
assistance becomes
weaker when the gear is
changed.
This is because the computer sets the
pedal assistance to the optimum level.
This is not a malfunction.
A noise can be heard
after switching.
Contact your specialist dealer.
It is normal to hear a
noise coming from the
rear wheel when cycling
as normal.
The gear shift setting may not have
been made properly.
Contact your specialist dealer.
If you stop the pedelec,
gear transmission does
not switch to the position
pre-configured in the
functional feature.
You may have applied too much
pressure onto the pedals.
It is easier to change gears if you press onto the pedals gently.
