14 Environmental Protection

Metabo packaging is 100% suitable for recycling.
Power tools and accessories at the end of their
service life still contain large amounts of valuable
raw materials and plastics which can likewise be
fed back into a recycling process.
As the dust generated during grinding/cutting may
contain harmful materials, do not dispose of it
along with domestic waste but ensure it is taken to
a collection point for special waste for proper
disposal.
These Operating Instructions are printed on paper
produced in a chlorine-free bleaching process.
