Polishing

When polishing to HiPERFLOOR Premium with PG820 RC, follow the process described in the 'HiPERFLOOR
Premium' product sheet up until the polishing steps with 3000 grain. When changing the polishing discs in this case, the
number of polishing discs should be 9 under the machine as the PG820 RC is heavier than the PG820 and has more
friction on the surface.
