Before use, be sure to turn the steel ball with the fingers about the axis of the shaft 2 or 3 times
both clockwise and counterclockwise so that the steel ball rests properly on the end of the shaft.

Note
•
Do not turn the steel ball more than 180
°
in either direction since a spring is connected to it.
•
Do not pull the steel ball and let it spring back sharply against the end of the shaft.
