How do I replace the needle on the XH2164-001?

Turn off the machine before changing the needle to prevent injury if the foot controller is accidentally pressed. Place fabric or paper under the presser foot to prevent the needle from falling into the needle plate hole, then turn the needle clamp screw counterclockwise to remove the old needle. Insert the new needle with the flat side toward the back of the machine until it touches the stopper, then tighten the needle clamp screw with a screwdriver without using excessive force. (Page 1)
