CAUTION:
When operating the tool by pulling the trigger, there may be a momentary lag before rotation starts. This does not signal a malfunction.
*This lag occurs as the tool’s circuitry starts up when the trigger is pulled for the first time after installing a new battery pack or after the tool has not been used for at least 1 minute (or at least 5 minutes when the LED is on). Rotation will start without any lag during second and subsequent operations.
