Grinding of surfaces
Only perfect sanding sheets yield good sanding per-
formance and prevent the machine from damage.
– Make sure the grinding pressure is even. Low grind-
ing pressure leads to increased grinding perform-
ance and prevents the machine and the grinding
tools from damage.
– Depending on the surface to be processed, differ-
ent rubber backing pads or sanding sheets are to
be used.
