I have one of those. They don't typically need lubing. The screw on the front has a point inside that rubs across the teeth of a gear when the plunger is pressed. The tip of that screw wears out from use. To adjust put a screwdriver in the slot to hold the screw and loosen the nut. Then adjust the screw in a try the plunger. Too far out and there will be no sound. Too far in and there will be too much resistance. Once the screw is in the correct spot and the desired sound is attained tighten the nut against the diaphragm.

If I remember correctly this one is a Seiss brand.
