unintentionally.
CAUTION
!
Crash caused by material fatigue
If the service life of a component has expired, the 
component may suddenly fail. Such damage may 
cause you to fall from the bicycle and injure yourself. 
  
The specialist dealer must perform an inspection at least every six months. 
This is the only way to ensure that the bicycle remains safe and fully 
functional.
 Remove the battery before the service. 
 Have the specialist dealer carry out six-monthly 
basic cleaning of the bicycle, preferably at the same 
time as the required servicing work.
 The specialist dealer will inspect the bicycle for any 
signs of material fatigue during basic cleaning.
 The specialist dealer will check the software 
version of the drive system and update it. The 
electrical connections are checked, cleaned and 
preservative agent is applied. The electrical cables 
are inspected for damage.
 The specialist dealer will dismantle and clean the 
entire suspension fork interior and exterior. They 
will clean and lubricate the dust seals and slide 
bushings, check the torques and adjust the fork to 
the rider's preferred position. They will also replace 
the sliding collar if the clearance is too great (more 
than 1  mm on the fork bridge).
