bumping Contact arm against workpiece with the Trigger being pulled.
*2: One screw is driven first by pushing Contact arm against workpiece, then by pulling
Trigger with the Contact arm kept pushed; screw cannot be driven when the steps are
reversed. Another one can be driven by releasing Trigger, then by repeating the steps;
however, cannot be driven if Trigger is not released before repetition of the steps.
