13 Assembling the Power Tool
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.
12.2.2 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, @ 24.
12.2.3 Charge Status
The LEDs on the battery also show the battery's state of
charge.
To determine the battery's state of charge:
1
0458-805-8621-A
► Press the button (1) on the battery.
The LEDs on the battery will glow or flash green for about
5 seconds and indicate the state of charge (see
illustration).
For example:
If four green LEDs glow continuously: full charge.
If one green LED is flashing: less than 20 % charge.
