1 A short beep
This means that the acoustic signal works as it should.
2 Four long beeps
This means that the battery's state of charge is low.
Recharge the battery.
3 Rapid succession of short beeps
This means that there is a malfunction in the battery. The
Signal stops automatically after a few seconds.
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.

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.
