WARNING Read all safety notices and instructions.
Failure to follow the safety instructions and guidance may result
in an electric shock, fire and/or severe injury.
The term “grass trimmer” as it appears in these safety instructions
refers to the mains-powered grass trimmer (with mains cord) and
to the battery-powered grass trimmer (without mains cord).
a) Protect the electric parts against moisture.
While cleaning and operating, never dip them in water
or other liquids to avoid an electric shock. Never hold the
grass trimmer under running water.
b) Switch off the grass trimmer, remove the battery and allow
the grass trimmer to cool down before carrying out any
assembly, conversion, cleaning or maintenance work, or
before storing or transporting the grass trimmer.
c) Switch off the grass trimmer and remove the battery
before replacing any accessories, before cleaning it, or
when it is not in use.
Special safety instructions for cordless tools
a) Charge the rechargeable batteries only in chargers
recommended by the manufacturer. Chargers that are
only suitable for certain rechargeable battery types pose a
risk of fire if used with other rechargeable batteries. Only
use the rechargeable batteries designated for use in
power tools. Using other rechargeable batteries may
result in injury and a risk of fire.
b) Keep the unused rechargeable battery away from
paper clips, coins, keys, nails, screws or other small
metallic objects that could bridge the contacts. A short
