Screw connections
It is vital that all bolted connections on the
S-pedelec have the correct torque in order to en-
sure that they are secure. Too much torque can
damage the screw, nut or component. Always use
a torque spanner to tighten screw joints. You are
not able to correctly tighten these bolted connec-
tions without this specialist tool!
If a component specifies a torque for its bolt-
ed connections, then this should be strictly ad-
hered to. Please read the instructions provided by
the manufacturer, which often list the correct
mounting torques.
When a screw connection was treated with
threadlocking adhesive (screw adhesive, e.g. Loc-
tite), threadlocking adhesive must be used when-
ever this connection is opened, loosened or re-
tightened.
