English
To set up the charger:
2
1
► Insert the plug (3) into a properly installed wall outlet (4)
matching the voltage and electrical frequency stated on
the rating plate on the charger.
The charger runs a self-test immediately after it is plugged
in. The charger LED (1) will glow green for about 1 second,
then it will glow red briefly before going out. Once the LED
goes out, the self-test is complete and the charger is ready
to charge the battery.
► Position the power supply cord (2) so that it will not be
stepped on, tripped over, come in contact with sharp
objects or moving parts or otherwise be subjected to
damage or stress.

1
► Push the battery (2) into the charger (3) until it stops.
The LED on the charger (4) glows green when the battery
is charging.
The LEDs (1) on the battery glow green and show the

process is complete and the charger will shut itself off. The
battery can be removed from the charger.
► Disconnect the power supply cord from the electrical
outlet when the charger is not in use.
A battery is not fully charged when it ships from the factory.
STIHL recommends that you fully charge the battery before
using it the first time.
Operate the charger only indoors, in dry rooms and within an
ambient temperature range of 41 °F to 104 °F (5 °C to
40 °C).
The battery heats up during operation of the blower. If a hot
battery is inserted into the charger, it may be necessary for
it to cool down before charging starts. The charging process
begins only after the battery has cooled down sufficiently.
Charging time depends on a number of factors, including
battery condition and the ambient temperature. For a
complete list of approximate charging times, see
