Guarantee and after-guarantee service of the HSW S.A. and HSW-Trading Ltd. machines is carried out countrywide by the HSW S.A. Service Office. The Office is responsible for start-up surveys, periodical inspections, as well as running guarantee repairs, and customer-ordered paid repairs. HSW S.A. also carries out technical expertises for secondhand machines for repurchase.

The experienced servicing teams of the HSW S.A. Service Office are equipped with cars with complete repair accessories and are constantly in contact with their headquarters, so they can quickly and effectively accomplish required repairs. Similarly, guarantee surveys are realized from the moment a machine is implemented to work to the end of the guarantee period. The standard guarantee for the machines extends into 12 months from the date of purchase, or covers 1,000 working hours, depending upon which circumstance occurs first. Guarantee servicing for the machines is carried out by HSW S.A. and its servicing dealers network.
