How do I replace the needle on the XH2177-001?

Always turn off the machine before changing the needle to prevent injury if the foot controller is accidentally pressed. Turn the needle clamp screw counterclockwise to loosen it, then insert the new needle with the flat side toward the back of the machine until it touches the stopper. Tighten the needle clamp screw with a screwdriver, and place fabric or paper under the presser foot beforehand to prevent the needle from falling into the needle plate hole. (Page 1)
