Foreword
Good servicing requires extensive and relevant training as well as comprehensible reference
documents.
We therefore regularly offer all service technicians both basic and ongoing training courses for the
full range of our products.
In addition we produce service handbooks for the major equipment which can be used initially as
instructional material and subsequently as sources of reference.
Furthermore we regularly distribute service information bulletins that provide details about further
developments to the products.
