Acoustic Signals
12.1 STIHL AP Battery
12.1.1 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 tempera‐
ture 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.
12.1.2 Power Tool Status
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.
For troubleshooting information,
12.1.3 Charge Status
