The SO-206 machine is designed for polishing parquet and other wooden floors, as well as cleaning them from old paint, varnish and dirt.
The machine has two models:

• SO-206 with a single-phase drive (a. c. mains, 220 V, 50 Hz).
• SO-206.1 with a three-phase drive (a. c. mains, 380 V, 50 Hz).

All assemblies and mechanisms of the machine are mounted on the body representing a box-type monoblock aluminum-alloy casting with a suction pipe and a spiral casing of the fan.
The grinding drum is a working member of the machine and is cantilever-wise fastened on the taper section of the shaft with a special nut. By rotating this nut in the direction opposite to that of tightening the drum is easily removed from the shaft without use of any special devices The elastic surface of the grinding drum increases the life term of the sanding paper and the quality of floor treatment. The clamping rolls of the drum ensure good tightening and reliable fastening of the sanding paper. The sanding papers are available in a variety of grain sizes depending on the requirements for the surface to be polished.
The pressure of the drum onto the surface to be polished is adjusted with a nut and a compression spring. The parallel positioning of the drum with respect to the surface to be polished is achieved by setting the lateral wheels at equal height with the help of an eccentric.
Sawdust produced in the process of polishing is exhausted by the fan into a dust collector. The machine offers a possibility to polish the floor in close proximity to the walls. The front cover is fitted with a guard roller, which prevents hitting of the drum against the wall or plinth during operation.
The front cover is easy to raise and can be fixed in its extreme positions, thus providing free access to the drum.
