► 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 backpack
battery before using it the first time.
Operate the charger indoors in a dry room. For optimum
performance, STIHL recommends operating the charger
within an ambient temperature range of 41 °F to 104 °F
(5 °C to 40 °C).
The battery heats up during operation of the power tool. If a
hot battery is connected to 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
www.stihl.com/charging-times.
9.1 Battery Status
Six LEDs and an acoustic signal indicate the status of the
battery.
1 A short beep
The acoustic signal works as it should.
2 Three short beeps
The Bluetooth® signal is switched on or off.
3 Six long beeps
The battery's charge is low. Recharge the battery.
4 Rapid succession of short beeps
There is a malfunction in the battery. The signal stops
automatically after a few seconds. Do not attempt to
charge, use or store the battery. Replace the battery.
These LEDs can glow or flash green, red or blue.
If the first LED on the right side glows blue for about three
seconds and three short beeps are emitted: the Bluetooth
®
interface is turned on.
If the first LED on the right side flashes blue six times and
three short beeps are emitted: the Bluetooth
®
interface is
turned off.
► Be aware that your ability to hear the acoustic signal may
be reduced when wearing hearing protection.
9.2 Power Tool Status
When the battery is connected to the power tool, the same
LEDs on the battery will indicate the status of the power tool.
If three LEDs glow red continuously: the power tool motor is
too hot. Allow the motor to cool down.
If three LEDs flash red when you activate the trigger switch:
the power tool has an electrical malfunction. Do not operate
the power tool. Have it checked by an authorized STIHL
servicing dealer before use or storage.

If one LED glows red continuously: the battery is
either too hot or too cold. Allow the battery to
warm up or cool down gradually at an ambient
temperature of about 50 °F to 68 °F (10 °C to
20 °C).
If the four right side LEDs flash red and a rapid
succession of several short beeps is emitted: the
battery has a malfunction and must be replaced.
Do not attempt to charge, use or store the
battery.
