Rechargeable Battery Pack

This long life battery pack must be recharged when
it fails to produce sufficient power on jobs which
were easily done before. At the end of its technical
life, discard it with due care for our environment:
• Run the battery pack down completely, then
remove it from the tool.
• Li-Ion cells are recyclable. Take them to your
dealer or a local recycling station. The collected
battery packs will be recycled or disposed of
properly.
