11.1 LEDs on the Battery

11.1.1 Battery Status

Four LEDs show the status of the battery. These LEDs can
glow or flash green or red.
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 all 4 LEDs flash red: the battery has a
malfunction and must be replaced. Do not
attempt to charge, use or store the battery.
11.1.2 Trimmer Status
When the battery is inserted in the trimmer, the same LEDs
on the battery will indicate the status of the trimmer.
If three LEDs glow red continuously: the trimmer motor is too
hot. Allow the motor to cool down.
If three LEDs flash red when you activate the trigger switch:
the trimmer has an electrical malfunction. Do not operate the
trimmer. Have it checked by an authorized STIHL servicing
dealer before use or storage.
