What to do if 3 LEDs flash red on my Stihl HTA 66?

If 3 LEDs flash red on your Stihl Pole Saw, it indicates a malfunction. Remove the battery, clean the electrical contacts in the battery compartment, and reinsert the battery. Then, switch on the pole pruner. If the issue persists, do not use the pole pruner.
