The initial stage of work is the cycle of parquet. To do this, use coarse -grained abrasive No. 40. The first thing to do is to walk around the perimeter of the room along the walls in both directions, while installing the width of the drum for 200 mm. After that, by half reducing the capture of the drum, you should walk along the diagonals, and then move around the room in the direction of the Parquet pattern.
