The downward motion continues as long as the start button is pressed. The processis completed when the set depth is reached (position 7, illustration 4-004-01) or when the depth gauge hitsan obstruction. If the start button is released or the depth gauge meets an obstacle, the vertical bore headgoes back up.Horizontal bore head:In order for the horizontal bore head to work, the workpiece must be clamped down with the swinging insertiondie arm. The selector switch “3” (illustration 4-004-01) must be turned to the right. Activating the startbutton “4” (illustration 4-004-01) initiates a movement of the horizontal bore head towards the front until theset drilling depth is reached by means of a revolver stop “12: (illustration 4-004-01). Releasing the startbutton makes the horizontal bore head move back again.The star in your cabinet37
