8.4 Adjusting the height of the table
Ȝ Slacken the tightening screw (6).
Ȝ Move the table (7) to the required position by
lifting or lowering and turning to the left or right
as required.
Ȝ Position the table (7) so there is still a big
enough gap between the workpiece and the tip
of the bit for you to start up the drill in idle.
Ȝ Re-tighten the tightening screw (6).
If you want to drill a hole all the way through the
workpiece, make sure that the hole in the table (7) is
centrally positioned relative to the bit.
When working with large workpieces you can swing
the table (7) completely to the side in order to place
the workpiece directly on the base plate.
