C A U T I O N !
For a continuous and troublefree operation of the coupling it must be designed according to
the selection instructions (according to DIN 740 part 2) for the particular application
(see BoWex-ELASTIC
®
-catalogue).
If the operating conditions (performance, speed, changes at engine and machine) change,
the coupling selection must be checked again.
