WARNING

Risk of Injury

Do not start the tool before assuring that the drill head is correctly assembled to the drive unit. An incorrectly assembled drill head may come loose with high speed and cause bodily injury and/or property damage.

Check that you hear a click sound to ensure that the units have been correctly assembled.
Check that the lock ring is flush with the nut.
