However it is advised to keep the machine constantly in movement for an optimum grinding result.
For soft floors it is recommended to work on high disc speed, for hard floors and the first steps of polishing it is
recommended to grind with low speed of the tools.
On hard floors and during polishing it is recommended to have a low grinding pressure.
In case of emergency or operating trouble, like vibrations or strong noises, switch the machine off
immediately!
