SCRAPPING THE MACHINE
The machine should be consigned to an authorised disposal organisation, which will manage disposal correctly, especially with regard to the oil and
fluids, filters, and batteries. ABS and metal parts should be recycled as secondary raw materials. Rubber hoses and gaskets, and ordinary plastic and
fibreglass, must be separated and consigned to municipal waste companies.
The packing of the machine is manufactured by recycling materials. Consign the spent materials to operators authorized to dispose.
