A method for using a SWING-type mixing device, the method comprising: - turning a main turning axle of the mixing device back and forth around its axis, that is in turns to a first direction all the way to a first turning point and to a second direction all the way to a second turning point for getting other turning axes fixed to the main turning axle and a container (5, 20) of mixable substance into a SWING-type movement; characterised by - monitoring the turning of the main turning axle by one or several sensors (18, 19, 25); - turning the main turning axle back and forth around its axis in accordance with the following steps a) - d): a) subjecting the main turning axle to a force turning it to the first direction until the sensor (18, 19, 25) detects the main turning axle having turned at a certain distance from the first turning point, whereby the force turning into the first direction is terminated, b) allowing the main turning axle to turn to the first turning point and back therefrom by mass inertia of the mixing device until the sensor (18, 19, 25) detects the main turning axle having turned at a certain distance from the first turning point; c) subjecting the main turning axle to a force turning it to the second direction until the sensor (18, 19, 25) detects the main turning axle having turned at a certain distance from the second turning point, whereby the force turning into the second direction is terminated, d) allowing the main turning axle to turn to the second turning point and back therefrom by mass inertia of the mixing device until the sensor (18, 19, 25) detects the main turning axle having turned at a certain distance from the second turning point. - turning a main turning axle of the mixing device back and forth around its axis, that is in turns to a first direction all the way to a first turning point and to a second direction all the way to a second turning point for getting other turning axes fixed to the main turning axle and a container (5, 20) of mixable substance into a SWING-type movement; - monitoring the turning of the main turning axle by one or several sensors (18, 19, 25); - turning the main turning axle back and forth around its axis in accordance with the following steps a) - d): a) subjecting the main turning axle to a force turning it to the first direction until the sensor (18, 19, 25) detects the main turning axle having turned at a certain distance from the first turning point, whereby the force turning into the first direction is terminated, b) allowing the main turning axle to turn to the first turning point and back therefrom by mass inertia of the mixing device until the sensor (18, 19, 25) detects the main turning axle having turned at a certain distance from the first turning point; c) subjecting the main turning axle to a force turning it to the second direction until the sensor (18, 19, 25) detects the main turning axle having turned at a certain distance from the second turning point, whereby the force turning into the second direction is terminated, d) allowing the main turning axle to turn to the second turning point and back therefrom by mass inertia of the mixing device until the sensor (18, 19, 25) detects the main turning axle having turned at a certain distance from the second turning point. a) subjecting the main turning axle to a force turning it to the first direction until the sensor (18, 19, 25) detects the main turning axle having turned at a certain distance from the first turning point, whereby the force turning into the first direction is terminated, b) allowing the main turning axle to turn to the first turning point and back therefrom by mass inertia of the mixing device until the sensor (18, 19, 25) detects the main turning axle having turned at a certain distance from the first turning point; c) subjecting the main turning axle to a force turning it to the second direction until the sensor (18, 19, 25) detects the main turning axle having turned at a certain distance from the second turning point, whereby the force turning into the second direction is terminated, d) allowing the main turning axle to turn to the second turning point and back therefrom by mass inertia of the mixing device until the sensor (18, 19, 25) detects the main turning axle having turned at a certain distance from the second turning point.
