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.
► Be aware that your ability to hear the acoustic signal may
be reduced when wearing hearing protection.
12.2.2 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
