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.

WARNING: To reduce the risk of serious personal injury, turn tool off and disconnect battery pack before making any
adjustments or removing/installing attachments or accessories. An accidental start-up can cause injury.
