Assure that the sums of the two angles depart from the balancing mass should be less
than 180 degree.
Stop the machine, fix balancing mass on the rotor according to the result
presented by HG904. The balancing mass is removed or remained should consist with
the settings. Restart the machine. When the rotation speed becomes steady, press
