12 LED Diagnostics
12.1 LEDs on the Battery
12.1.1 Battery Status
Four LEDs show the status of the battery. These LEDs can
glow or flash green or red.
12.1.2 Blower Status
When the battery is inserted in the blower, the same LEDs
on the battery will indicate the status of the blower.
If three LEDs glow red continuously: the blower motor is too
hot. Allow the motor to cool down.
If three LEDs flash red when you activate the trigger switch:
the blower has an electrical malfunction. Do not operate the
blower. Have it checked by an authorized STIHL servicing
dealer before use or storage.
For troubleshooting information, @ 23.
12.1.3 Charge Status
The LEDs on the battery also show the battery's state of
charge.
To determine the battery's state of charge:
► 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.
12.2 LED on the Charger
One LED shows the status of the charger. The LED can glow
green or flash red.
12 LED Diagnostics
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.
If the LED glows green continuously: the battery
is being charged.
