Lawn clippings should be 
composted and not disposed of 
in household waste.
The machine, its packaging and 
accessories are all produced 
from recyclable materials and must be 
disposed of accordingly.
By disposing of materials separately, and 
in an environmentally friendly manner, 
valuable resources can be re-used. For 
this reason, the machine should be 
disposed of for recycling at the end of its 
useful life. Pay particular attention to the 
information in the "Disposal" section 
during disposal (Ö 4.12).
Consult your recycling centre or your 
specialist dealer for information on the 
proper disposal of waste products.
Always dispose of batteries 
properly – observe local 
regulations. Do not dispose of 
batteries with domestic waste, 
but hand it in to a specialist 
dealer or at a hazardous waste collection 
point.
