13 LED Diagnostics and Acoustic Signals

13.1 STIHL AP Battery

13.1.1 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.
13.1.2 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.
