What does the red LED indication on the side mean while activating the tool?
The display lights when the battery has passed the 75% depletion level. The LED display will light when the trigger is depressed to indicate the battery is almost spent. It may also light when the cut or compression reaches the top cycle. The flashing display serves as a reminder to have a spare battery on hand. Continue to operate the tool until it does not respond to the pull of the trigger. Remember to let the battery cool before charging.
