Mark the screw positions on the top of the board. The hole should not be in a groove or notch on the board.

Place the drilling template on the floorboards and use the side notch to adjust the rear drill bushing exactly to the corresponding marking line.

In the same way, adjust the front drill bushing to the second line using the side adjustment notch. Then place the floorings exactly on the wooden beams. Caution: Use the long holes on the first board

Insert a spacer between the boards every 80 cm. Use the tab to align the drilling template with the existing row of screws and drill the screw holes briefly.

Then drill and lower holes without drilling template. The lowering depth can be precisely adjusted with the push-on sink.

If all holes are drilled in the entire floorboard, screw the floorboards in the center onto the wooden beams. With the terrace-building clamp, even curved floorboards can be straight drawn without any problems.
