Neck Replacement

NOTE: Remove consumables (retaining head, nozzle and contact tip) before installing the neck. Failure to do so will result in improper installation.

1. Twist the hand nut clockwise to UNLOCK. IMPORTANT: To prevent damage to the neck, ensure that the hand nut is always in the UNLOCK position when inserting a neck.
2. Insert the neck into the connector housing. IMPORTANT: The neck is fully inserted only when the neck bottoms out and the insertion depth guide (INSERT TO HERE) on the neck meets up with the connector housing.
3. Release the hand nut allowing it to return to the LOCK position. IMPORTANT: Do not release the hand nut unless the neck has been fully inserted or damage to the neck may result.
