the various types of material they are made from (plastic, metal sheets, polyurethane,

copper, etc.) into groups according to their features.

All recyclable materials and waste should be processed and recycled by professionals, in

compliance with the laws of the country in question.

The company responsible for recycling the materials should be registered and certiﬁed as a

waste disposal service in accordance with the speciﬁc directives of the country in question.

Attention

Illegal disposal of the product by the owner will result in administrative sanctions as required by cur-

rent laws.

Disposal of the product should comply with current laws on the disposal of coolant liquids and mineral

oils.

Important

If there is no symbol representing a barred dustbin on the equipment, this means that the manu-

facturer is not responsible for taking care of the disposal of the product. In this case, again, current

waste disposal laws should be complied with.
