Juki Pro 2000 noise

You can chase a noise by using a screwdriver with a plastic hand grip (not rubber) place the handle  just behind the ear and use the tip of the driver to place on expected parts a longer screwdriver is better

"Pull the cone off the tip and lousy move the hose end around if you don’t have one most auto parts stores or drug stores sell cheap ones."
you don't need a stethoscope..just a piece of vinyl tube ( like aquarium hose ) about 50 cm long.put one open end ( flat against the machine, so that it "seals" to the part you want to listen to ) the other end , you put loosely into your ear ( like "in ear" headphones ) ..Move the machine end around until you can "zoom in" on the area the noise is coming from..The "diaphragm" ( cone end ) of a stethoscope just acts as a sonic concentrator , the tubes act as the magnifying channels to get the sound to your ear..The "screwdriver" "trick" ( old mechanic's "lore" ) does much the same thing, but, it works better with a large handled screwdriver ( where the shaft goes right through the handle ) resting against the open part of the ear( not behind the ear) like headphones.Behind the ear works OK for low pitch noises ( via "bone inductance" ) but not so well for higher pitched sounds as if you put the handle end to the ear..without actually sticking it in your ear far enough to damage your ear :)

Make sure that your hair does not get caught in any moving parts, and that any moving parts do not hit you in the eye , nose, or elsewhere on the face , head, fingers etc..
