9.1 Procuring spare parts

were also certified by the manufacturer as
part of the declaration of conformity. If you

voiding the conformity of the product.
We strongly recommend that you use ori-
ginal spare parts from the manufacturer as
this guarantees fault-free and safe opera-
tion of the product. To receive information

ance or repair work, use only the spare
