7.10 Reading the charge status LED display on Li­ion bat-
teries 7
NOTE
The charge status cannot be indicated while the power tool is in
operation. LED 1 blinks when the battery is fully discharged or
when it is too hot (temperature above 80°C). The battery must then
be inserted in the charger. If all 4 LEDs blink, this indicates that
the power tool has been overloaded or has overheated.
CAUTION
If the battery gets too hot to touch, this may indicate that it is
faulty. Place the tool in a location where it can be kept under
observation, well away from flammable materials, and allow it
