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.
