Variable Speed Control Trigger
To set the center of a hole, pull the
trigger slightly to start the drill rotation
slowly.
The more the speed control trigger is
pulled, the higher the speed becomes.
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.
