After A Crash; Unusual Noises - Schindelhauer Bikes Oskar Benutzerhandbuch

7.3. After a crash

After a crash or an accident, please check if parts of your e-
bike and the drive train are damaged. Potential risk of
breakage! Never try to straighten bent parts.
Have your e-bike checked by a specialised dealer. If defects
can't be ruled out completely the parts in question have to
be replaced.
If parts of the e-bike system are visibly damaged (cables,
drive unit, battery) danger of an electrical shock might be
imminent! In this case, immediately remove the battery and
contact your Bosch specialised dealer.

7.4. Unusual noises

Rattling noises:
If the cause of rattling noises can't be localised, check the following parts for
loose fasteners:
• handlebar
•
stem
• brake calipers
• kickstand
• valve nuts of the inner tubes
• mudguards
• front and rear rack
Retighten loose bolts with the appropriate torque (chapter 11, page 103).
Clicking noises:
Clicking noises can be caused by insufficient use of assembly paste. Always
apply assembly paste to the contact surfaces of the following bolted
connections:
• handlebar – stem
•
seat post – frame
• saddle rails – seat post
• pedals – crankarms
Grinding noises:
Grinding noises occur when a moving part of the e-bike rubs against a
stationary part or when debris is caught in the drive train or between tyre
and mudguard. Examine your e-bike for the following causes of noise:
• Does one or both brake discs rub against the brake pads in a
matter causing the spinning wheel to slow down?
• Does the tooth belt or the front sprocket touch the motor cover?
• Do parts of the mudguards touch the tyres?
If one or more of these things apply to your e-bike, please contact your
specialised dealer for adjustment or repair.
If unusual noises can't be stopped, contact your specialised
dealer early to avoid possible damages to your e-bike in the
long run.
