Claim 5:
6. The method as claimed in claim 1, wherein the device is further equipped with a second drive cylinder for receiving hydraulic fluid, a second drive piston, which is movably arranged in the second drive cylinder, a second delivery cylinder for receiving and releasing thick matter, a second delivery piston, which is movably arranged in the second delivery cylinder, and a second piston rod, which is fastened to the second drive piston and to the second delivery piston for coupled movement of the second drive piston and the second delivery piston,
wherein the first drive piston separates a drive-pump-side volume from a swing volume in the first drive cylinder,
wherein the second drive piston separates a drive-pump-side volume from a swing volume in the second drive cylinder, and
wherein the swing volume in the first drive cylinder and the swing volume in the second drive cylinder are connected to one another via a swing connection for exchanging hydraulic fluid in such a way that the first drive piston moves in phase opposition to the second drive piston,
the method further comprising:
determining a speed of the second drive piston, wherein the expected speed of the first drive piston is the same as the determined speed of the second drive piston.
