Recommended Torque Settings - Centurion Backfire E 640.27 Translation Of The Original Operating Instructions

Recommended torque settings

All bolted connections of the pedelec components have to be tightened carefully and checked regularly to ensure the safe and reliable operation of
the CENTURION pedelec. This is best done with a torque wrench that disengages at the desired torque value or a click-type torque wrench. Tighten
carefully by approaching the prescribed maximum torque value in small steps (0.5 Nm increments) and check in between the proper fit of the com-
ponent. Never exceed the maximum torque value indicated by the manufacturer!
Where no maximum torque setting is given start with 2 Nm. Observe the indicated values and observe the values on the components and/or in the
operating instructions of the component manufacturers on the enclosed CENTURION CD-ROM.
