X
The start of the charging process is indicated by the red
control light ("X", Fig. 2) at the end of the handle. If the
battery is completely empty the charging time is about
3-5 hours. After the battery has been fully charged, the
electronic control automatically switches off the charging
process. The red control light then changes its colour to
green indicating the end of the charging process. It is not
required to monitor the charging time.
The charging unit and the handle of the tool heat up dur-
ing the charging process. This is nothing unusual.
Pull the plug of the charging unit if it is not in use.
The tool must never be switched on during the charging
process!
Recharge the battery every time you realise a consider-
able decrease of the tool's cutting performance. The
battery additionally features an electronic total discharge
protection that protects the battery from damage. This
feature switches the battery off if the discharging thresh-
old is reached. Do not switch the tool on afterwards and
make sure to recharge the battery first.

Switching the tool on/off

Always keep hands and feet away from the
cutting tools, particularly when switching on
the motor!
