Bolted connections
It is vital that all bolted connections
on the pedelec have the correct
torque in order to ensure that they
are secure. Too much tightening torque may
damage the screw, nut or component. You
must use a torque wrench. You cannot prop-
erly tighten the bolted connections without
this special tool!
Adhere to any specified torque val -
ues where indicated for compo-
nents. Please read the instructions
provided by the manufacturer, which lists
the correct mounting torques.
